    ABSTRACT: This prospective study was evaluated the role of TH agglutinins and reevaluate the diagnostic value of Widal test in the diagnosis of typhoid fever by identifying the S. typhi specific antibody. The study was carried out in the department of Microbiology, Mymensingh Medical College, Mymensingh between July 2010 and June 2011, including 200 individuals of different ages and sexes. Widal test and blood culture were performed for each of the cases and controls. Among 150 blood samples from the suspected cases, 23(15.3%) were culture positive for S. typhi and 67(44.7%) had high titres of ≥1:160 for 'O' or 'H' or both agglutinins. Out of 23 culture positive cases, 3(13%) had TO ≥:160, 5(21.7%) had significant TH ≥1:160. Based on the above findings, it was concluded that judicious interpretation of Widal test play an essential role in diagnosis of typhoid fever, especially in the resource poor countries like Bangladesh.

    ABSTRACT: Campylobacteriosis is a collective term, used for infectious, emerging foodborne disease caused by Campylobacter species comprising Gram negative, curved, and microaerophilic pathogens. The true incidence of human campylobacteriosis is unknown for most countries of the world including Bangladesh. But campylobacteriosis is not uncommon in our country. Due to its increasing incidence in many countries of the world, it is an important issue now a day. Animals such as birds are the main sources of infection. Farm animals such as cattle, poultry are commonly infected from such sources and raw milk, undercooked or poorly handled meat becomes contaminated. Transmission of campylobacteriosis to human occurs through consumption of infected, unpasteurized animal milk and milk products, undercooked poultry and through contaminated drinking water. Contact with contaminated poultry, livestock or household pets, especially puppies, can also cause disease. Due to variability of clinical features and limited availability of laboratory facilities, the disease remains largely under-reported. Early and specific diagnosis is important to ensure a favourable outcome regarding this food borne disease. Antibiotic treatment is controversial, and has only a benefit on the duration of symptoms. Campylobacter infections can be prevented by some simple hygienic food handling practices.

    ABSTRACT: Extended spectrum β-lactamases (ESBLs) are produced by Gram negative bacteria showing resistance to new generations of antimicrobial agents. This study was undertaken to characterize ESBL producing bacteria from 222 urinary isolates. Antimicrobial resistance was screened by disc diffusion test. The ESBL status was confirmed by double disc diffusion test (DDDT) and minimum inhibitory concentration (MIC) by agar dilution method by standard procedure. The study revealed the following distribution of ESBL producing isolates: Klebsiella spp (81.6%), Proteus spp (78.1%) E. coli (72.3%) and Pseudomonas spp (66.7%). All the isolates were sensitive to imipenem and nitrofurantoin followed by amikacin 92.9%. A relatively higher rate of resistance to gentamicin, co-trimoxazole, azithromycin and quinolones were also observed for ESBL producers. The study suggested routine detection of ESBL and avoidance of irrational use of third generation cephalosporins to reduce the emergence of multidrug resistance bacteria following an antibiotic policy.

    ABSTRACT: This cross sectional descriptive study was to measure the thyroid angle and to establish the difference between sexes of different age groups in Bangladeshi cadaver. A total 60 human larynges were collected by purposive sampling from October 2008 to March 2009. Among them 45(male 23 and female 22) were collected from Bangladeshi cadavers (9 to 60 years) at the autopsy laboratory of Department of Forensic Medicine and 15 (male 6 and female 9) from stillborn infants of viable age (28 to 40 weeks of gestation) from Gynaecology and Obstetrics Department of Mymensingh Medical College, Mymensingh. The thyroid angle was measured and significant differences of the dimensions between different age and sex groups were observed. In the present study observed findings was compared with those of other researchers. The mean±SD thyroid angle was found as 65.00±11.65 degree in age Group A (28 to 40 weeks of gestation), 73.69±6.56 degree in age Group B (9 to 16 years) and 77.76±7.76 degree in age Group C (17 to 60 years). The mean thyroid angle was higher in female (83.1667±5.78220 degree) than that in male (73.9412±7.09460 degree) and statistically moderately significant in Group C, where t = 3.853 and p = 0.001. In statistical analysis, differences between age and sex groups were calculated by using Students (unpaired) 't' test. The present study revealed that the value was significantly greater in adult female than male and the value increased with age.

    ABSTRACT: Pre-eclampsia along with its complications seems to be one of the major causes of maternal morbidity and mortality. Despite numerous studies, the etiology of pre-eclampsia has not yet been fully elucidated. The present study prospectively determines and evaluate whether maternal serum levels of calcium has any association with pre-eclampsia. It was a cross sectional study carried out in the department of Biochemistry, Mymensingh Medical College from July 2009 to June 2010. A total of 76 subjects were selected with the duration of pregnancy from 28th wks to term. Among them 42 were normal pregnant women and 32 were pre-eclamptic, admitted in the department of obstetrics and gynaecology Mymensingh Medical College Hospital. The mean±SD serum calcium of normal pregnant women and that of the pre-eclamptic were 7.62±0.24 and 7.32±0.28mg/dl respectively. There was significant (p<0.001) decrease in serum calcium in subject with pre-eclampsia in comparison to that of the normal pregnancy. So, level of calcium may be significantly decreased in pre-eclampsia.

    ABSTRACT: The development of antibiotic resistance in bacteria following introduction of antimicrobial agents has emerged as an important medical problem everywhere in the world including Bangladesh. Extended spectrum β-lactamases (ESBLs) are rapidly evolving group of β-lactamase enzymes produced by the Gram negative bacteria. This study was undertaken to characterize ESBL producing gram negative bacilli from urine, skin wound (pus and wound infection). A total of 300 gram negative bacilli were screened for resistance to third generation Cephalosporins (3GCs) by disc diffusion test. The ESBL status was confirmed by double disc diffusion test (DDDT), minimum inhibitory concentration (MIC) by agar dilution method as recommended by Clinical Laboratory Standard Institute 2010 (CLSI) and multiplex PCR for TEM, SHV and CTX-M, CTX-M-3, CTX-M-14 genes. The present study revealed a higher occurrence of multi drugs resistant ESBLs production among gram negative isolates where Klebsiella spp. were the leading bacteria 36/45 (80%), followed by Proteus spp. 40/55 (72.7%), Esch. coli 105/156 (67.3%) and others 25/35 (71.4 %). Rate of TEM, SHV and CTX-M genes present in study population were 50.46%, 18.69% and 46.72% respectively. Among the CTX-M positive genes CTX-M-3 and CTX-M-14 were 78.0% (39/50) and 80.0% (40/50) respectively. Results indicate that routine ESBL detection should be made mandatory and irrational use of third generation cephalosporins must be discouraged to reduce multi drugs resistance bacteria, to increase patients' compliance and to make an antibiotic policy.

    ABSTRACT: This case control study was carried out in the Department of Biochemistry, Mymensingh Medical College, Bangladesh in cooperation with the Outpatient Department and Medicine Units of Mymensingh Medical College Hospital, Fulbaria Upazilla Health Complex, Mymensingh and some DOTS centers of BRAC, a non-government organization during the period of July 2006 to June 2007. The aim of the study was to explore the status of serum calcium level in smear positive Bangladeshi pulmonary tuberculosis patients. A total of 120 people of different age groups were included in this study. Subjects were divided into two groups - Group I (Control; n=60) apparently healthy people selected matching by age, sex and socioeconomic status with the cases and Group II (Case; n=60) people with smear positive pulmonary tuberculosis. Serum calcium was estimated by colorimetric principle. Serum calcium was adjusted by serum albumin concentration. Statistical analysis was done by using SPSS windows package. Among the groups, mean±SD of adjusted serum calcium in Group II (2.41±0.15mmol/L) was significantly higher (p<0.001) than that in Group I (1.85±0.11mmol/L). It is evident from the study that serum calcium level significantly increases in smear positive Bangladeshi pulmonary tuberculosis patients.

    ABSTRACT: The antimicrobial susceptibility of 80 coagulase-negative staphylococci (CoNS) isolates from surgical wound, pus from infected skin lesions, burn exudates and diabetic ulcer exudates of patients in Mymensingh Medical College Hospital, Bangladesh, was evaluated in order to see their pattern of antimicrobial resistance. The study was carried out in the department of Microbiology, Mymensingh Medical College during the period from July 2009 to May 2011. The 80 CoNS isolates were subjected to antimicrobial susceptibility to relevant antibiotics including oxacillin by disk diffusion method. Out of 80 CoNS isolates, the highest number were resistant to oxacillin 36(45%), followed by gentamicin 32(40%), cefuroxime 25(31%), ceftriaxone 24(30%) and ciprofloxacin 18(22%). All isolates of CoNS were sensitive to imipenem and vancomycin. As MRCoNS were found multidrug resistant, therefore, antibiotic sensitivity must be done prior to treatment in infections caused by these species.

    ABSTRACT: Typhoid fever is a severe systemic infection endemic in many developing countries, including Bangladesh. Present study evaluated immunochromatographic test (ICT) and Widal test in the early diagnosis of typhoid fever cases. The study was carried out in the department of Microbiology, Mymensingh Medical College, Mymensingh between July, 2010 and June, 2011, including 200 individuals of different age and sex. Of them, 150 were clinically suspected cases of typhoid fever and 50 age-sex matched controls. Among 150 blood samples from the suspected cases 106(70.7%) were positive for IgM of Salmonella typhi by ICT and 67(44.7%) were positive by Widal test. Whereas, among the 50 controls 4(8%) were positive by ICT and 6(12%) were positive by Widal test. The sensitivity, specificity, positive and negative predictive value of the ICT was found as 83.3%, 92.00%, 91.9% and 83.6% respectively. On the other hand corresponding values for Widal test were of 44.4%, 88%, 80% and 59.5% respectively. Thus, The ICT (IgM) is better alternative to Widal test for early and accurate diagnosis of typhoid fever. The ICT (IgM) is rapid, easy to perform, applicable for field use and highly sensitive and specific for detection of antibodies in patients with typhoid fever.

    ABSTRACT: Acute diarrheal diseases are great concern throughout the world, as they are responsible for considerable morbidity and mortality, especially in developing countries. The present study was carried out during the period from January' 2011 to December' 2011 in the Department of Microbiology, Mymensingh Medical College. A total of 300 stool specimens were examined by standard laboratory methods for identification of enteropathogens. Rotavirus was detected by Polyacrylamide Gel electrophoresis (PAGE). Different diarrheagenic E. coli (DEC) were detected by Multiplex PCR following standard methods. Of the 300 stool specimens examined, Enteropathpgens were detected in 160(53.5%) cases. Rota virus was detected in 82(27.5%) cases, followed by DEC in 54(18%), Shigella spp. in 8(2.4%), Salmonella spp. in 5(1.6%), Entameoba histolytica in 4(1.5%) and Giardia lamblia in 3(1.0%) cases. Among the DEC, the Enterotoxigenic E. coli (ETEC) was most prevalent (72%, 39/54). The present study revealed a high prevalence of rotavirus and DEC as the predominant causes of diarrhea in this region.

    ABSTRACT: Despite the fact that diarrhaegenic Escherichia coli (DEC) has been identified as a major etiologic agent of childhood diarrhea which represent a major public health problem in developing countries, only a few studies have been performed in Bangladesh to identify these organisms. To detect DEC in patients with acute diarrhea, a total of 300 stool specimens were tested by multiplex polymerase chain reaction (PCR). The multiplex PCR was designed for the detection of target genes of "eae" for enteropathogenic E. coli (EPEC), "stx" for enterohemorrhagic E. coli (EHEC), "ipaH" for enteroinvasive E. coli (EIEC), "aspU", "CVD432" and "aggR" for enteroaggregative E. coli (EAEC) as well as "elt" and "est" for enterotoxigenic E. coli (ETEC). Out of 300 stool specimens collected from patients with acute diarrhea, the DEC was detected in 18% (54/300) cases. The dominating strain was ETEC (13%, 39/300), followed by EAEC (5%, 15/300) and no EHEC, EIEC and EPEC could be detected. Both heat-stable toxin (ST) and heat-labile toxin (LT) genes of ETEC were detected in 66.68% (26/39) strains and only ST or LT as single gene was detected in 23.07% (9/39) or 10.25% (4/39) strains respectively. The multiplex PCR assay could be used as a rapid as well as efficient diagnostic tool for identification of DEC in the clinical laboratory settings.

    ABSTRACT: To determine the volume of spleen of Bangladeshi people by water displacement method, this cross sectional descriptive study was carried out over 120 cadaveric spleen of which 87 male and 33 female, in the department of Anatomy of Mymensingh Medical College from July 2007 to June 2008. The maximum volume of male spleen was 200ml in group D (46-60years) and female spleen was 150ml in group B (16-30years). The minimum volume was 30ml in group A (upto15years) in both male and female. The maximum mean volume of male was 84.23 ml in group B (16-30years) and minimum mean volume was 47.75ml in group A (upto 15years). The mean volume of female spleen was highest, 78.33ml in C (31-45years) age group and lowest 45.62ml in A (upto 15years) age group. From this study it was evident that the volume of spleen increases with age during childhood and adolescence remains stable in young adult and declined in older age groups. Volume of spleen shows positive correlation with age up to 60 years of age. Mean±SE volume of male spleen was 75.27±3.78ml, ranges from 30-200ml and in female; mean±SE volume was 60.51±4.90ml, ranges from 30-150ml. Here it is observed that volume of spleen was higher in male than in female but the difference was not statistically significant.

    ABSTRACT: Staphylococci are Gram positive, non motile, asporogenous bacteria that characteristically divide in more than one plane to form irregular cluster. Species are classified as coagulase-positive Staphylococcus aureus and coagulase-negative staphylococci. Coagulase-negative staphylococci (CoNS) are reported to be the third causative agent of nosocomial infections and the most frequent cause of nosocomial bloodstream infections. Strains of CoNS those are resistant to methicillin referred to as Methicillin Resistant Coagulase Negative Staphylococci (MRCoNS). Now a days, MRCoNS has been increasing as a serious nosocomial pathogen having the property of multi drug resistance. The present study was conducted to see the species distribution, antibiotic resistance patterns and some virulence factors of CoNS isolated from different clinical specimens. This cross sectional descriptive study was carried out in the Department of Microbiology, Mymensingh Medical College during the period from July 2009 to May 2011. A total of 300 clinical specimens were collected for this study of which 240 were found culture positive as single isolate. Among them 110 were from surgical wound, 80 from pus of skin infections, 30 from burn ulcer exudates and 20 from diabetic ulcer exudates. A total of 80 strains of CoNS were isolated from them. Besides CoNS other isolated bacteria were S. aureus, Pseudomonas spp and Escherichia coli. The CoNS were initially detected by coagulase test. All the strains that were either slide or tube coagulase negative were further identified by different biochemical tests using a commercial kit HiStaph™ Identification Kit (HiMedia Laboratories Ltd) which comprise a set of 12 standard biochemical tests. A total of 16 species were identified. These were S. epidermidis, S. saprophyticus, S. caprae, S. haemolyticus, S. simulans, S. xylosus, S. hyicus, S. hominis, S. warneri, S. auricularis, S. lugdunensis, S. felis, S. capitis, S. chromogenes, S. carnosus and S. gallinarum. Of them S. epidermidis was the most prevalent (17%) followed by S. saprophyticus (15%), S. caprae (11%), S. haemolyticus (9%).

    ABSTRACT: Typhoid fever, caused by Salmonella typhi, is an important cause of morbidity and mortality in many developing countries. A rapid and sensitive method for the detection of S. typhi is essential for early diagnosis. This was a study to prospectively evaluate the sensitivity and specificity of nested polymerase chain reaction (PCR) to identify the S. typhi using flagellin gene related primers. The study was carried out in the department of Microbiology, Mymensingh Medical College, Mymensingh between July, 2010 and June, 2011, including 82 individuals of different age and sex. Of them, 62 were clinically suspected cases of typhoid fever and remaining 20 were apparently healthy controls. Cultures as well as PCR of blood specimens were performed for each of the cases. Among the 62 suspected typhoid fever cases, 8(12.9%) were blood culture positive and 55(88.7%) were PCR positive for S. typhi. All culture positive cases were positive by PCR and among 54 culture negative cases, 47(87%) were positive by PCR. Neither of the healthy controls was positive by PCR or blood culture. The sensitivity, specificity, positive predictive value and negative predictive value of PCR using blood culture as gold standard were 88.7%, 100%, 100% and 74% respectively for typhoid fever. In this study, the PCR appears highly specific, very sensitive and superior to blood culture for the early diagnosis of typhoid fever.

    ABSTRACT: This cross sectional descriptive study was done to observe the mean diameter of seminiferous tubules and to determine its differences between different age groups in Bangladeshi male. Thirty human testes of different age groups were collected by purposive sampling technique. Among them 22 specimens were collected from cadavers during routine postmortem examination and 8 specimens were from dead fetuses from Gynaecology & Obstetrics Department. The specimens were grouped into three categories Group A (28 to 42 weeks of gestational age), Group B (Up to 14 years) and Group C (15 to 70 years). The mean diameter of seminiferous tubules was measured and significant differences of the dimensions between different age groups were determined. The mean±SD diameter was 85.37±15.51 μm in Group A, 144.04±63.34 μm in Group B and 227.92±22.47 μm in Group C. Statistically, differences between age groups were calculated by using Unpaired Students 't' test. The present study revealed that the diameter increased with age and mean differences were statistically significant between Groups A&C, B&C and A&B.

    ABSTRACT: This cross sectional descriptive study was carried out to determine the length, breadth & thickness of isthmus of thyroid gland of Bangladeshi people. To fulfill this aim sixty postmortem tissue blocks containing thyroid gland and its neighbouring structures were collected by convenience sampling technique from 48 male and 12 female cadavers of different age groups, age ranging from 11 to 70 years and fixed and preserved in 10% formol-saline solution. Specimens were collected from dead bodies autopsied on different dates from October'2004 to February'2005 at the autopsy laboratory of Forensic Medicine Department of Mymensingh Medical College, Mymensingh, Bangladesh. Gross and fine dissection was carried out to study the length, breadth and thickness of isthmus of thyroid gland. In the present study, observed findings were compared with those of Western and Bangladeshi researchers. It was seen that the mean±SD lengths of isthmus were 10.42±7.49 mm, 10.17±5.70 mm and 9.33±6.64) mm in Group A(upto 18 years), B(19 to 45 years) and C(>45 years) respectively. Highest length (30mm) was observed in Group A and lowest length (2mm) was observed in Group C. Variance analysis showed that there was no significant difference in mean length between the age groups (F=0.086, p=0.918). The mean±SD values of breadth were 13.66±5.06 mm, 14±5.41 mm and 12.27±3.97 mm in Group A, B and C respectively. In the ranges, there was much overlapping among the groups. In Group B breadth of the isthmus was greater than other age groups. But these differences were statistically not significant, where F=0.430 & p=0.654. It was interesting to note that in this study the mean breadth of isthmus was significantly greater than the mean length (where, t=-2.727 and p=0.01). In the present study the mean±SD thickness of the isthmus of thyroid glands were 4.91±1.78 mm, 4.72±2.68 mm and 4.45±1.36 mm in three age groups respectively & the thickness of isthmus of thyroid gland was also greater in Group B than other two groups. But the variance analysis reveals that, there was insignificant difference in the thickness (F=0.133, p=0.876) of isthmus of thyroid gland among different age groups.

    ABSTRACT: A record based descriptive type of study was carried out among the under-graduate students of Mymensingh Medical College from the session 1966-67 to 2006-07. The academic years were divided into four decades and admission was followed into three categories such as retained, cancellation and drop-out. Total number of the students was 5892. Among them 3848(65.30%) were male and 2044(34.69%) were female. Out of 5892 students drop-out was 282(4.78%) and admission cancel was 304(5.15%). It was also found that drop-out in male was 232(6.02%) and in female was 50(2.44%) and admission cancel in male was 266(5.87%) and in female was 78(3.81%). The difference was found statistically significant (p<0.001). It was observed that gradually the drop-out and admission cancel rate is decreasing from the very beginning to till now. It was also observed that all drop-out and admission cancellation were in first & second year students. There was no continuation of their class roll numbers in third year registration.
