• Article: Sensitivity pattern and beta-lactamase production in clinical isolates of Aeromonas strains.

  ABSTRACT: Of the 43 Aeromonas spp. isolated from various clinical samples 94% isolates were Beta-lactamase producers. The isolates were tested for sensitivity by disc diffusion method which is commonly used in Pakistan. MIC was determined by using Epsilometer test (E-test) method. More than 80% isolates were sensitive to cephalosporins and quinolones. However, resistance to commonly used antibiotics was very high, 94% isolates were resistant to ampicillin which corresponds to the betalactamase production. More than 60% of the isolates were resistant to cotrimoxazole and 40% to chloramphenicol, hence quinolones and cephalosporins appear to be the drugs of choice for treating serious Aeromonas infections. The MIC range of Aeromonas was best for cefotaxime < 0.06 - 1.0 ug/ml. MIC 90 for cefotaxime was 0.50 ug/ml, for imipenem 0.25 ug/ml and for ciprofloxacin 2.0 ug/ml.

  ABSTRACT: One thousand and three diarrhoeal stool samples were processed in our laboratory during the period 1996/1997 for the presence of enteric pathogens especially Aeromonas spp., which has emerged as a new agent causing diarrhoea. Ampicillin sheep blood agar was found to be the best medium for the isolation of Aeromonas spp. from stool specimens. Enteric pathogens were found in 200 (20%) stools, of which Aeromonas spp. was the second commonest pathogen isolated amounting to 21% of isolates. This study clearly indicates that Aeromonas spp. must be looked for in every diarrhoeal stool samples, specially in children below 10 years of age. Isolation and identification is cost effective and easy, if the given protocol is observed.

  ABSTRACT: Trauma and non-traumatic insults can cause muscle damage to such an extent that serious sequelae to other organs may result. Myoglobinuria and subsequent acute renal failure (ARF) is a well known and widely studied fact of such sequelae. Twelve cases of ARF (between 1990-1993) who have developed renal dysfunction after prolonged muscular exercise e.g., squat jumping, sit-ups and blunt trauma from sticks or leather belts mainly given by law enforcing personnel for certain issues were studied. None of them had previous history of myopathy, neuropathy or renal disease. All were critically ill on presentation and required renal support in the form of dialysis. Although morbidity was high in all, eleven of them recovered and one expired due to sepsis.

  ABSTRACT: Beta Haemolytic Streptococci(BHS) carriage rate in pregnant women during labour and its acquisition by their newborns just after birth was investigated in 60 mother baby pairs. The carriage rate of group B Streptococci (GBS) was 11.6%, acquisition rate by newborns of carrier and non-carrier mothers was 85.7% and 1.8% respectively. A total of 28.5% newborns were carrying GBS on all the skin sites and were heavily colonized and therefore, at higher risk of developing early onset of Streptococcal infections. Penicillin G and Ampicillin were most effective antibiotics against GBS.

• Article: Frequency of Chlamydia trachomatis in pregnant women.

  ABSTRACT: Frequency of chlamydia trachomatis infection was investigated in eighty-five pregnant women by direct immunofluorescence (IF) and iodine staining methods. The overall frequency of true positive by both methods was 8.2%. Direct immunofluorescence method alone detected chlamydia infection in 16.5% women with 50% sensitivity and 93% specificity and by iodine method in 14.1% women with 58.3% sensitivity and 90.4% specificity. This shows that as compared to IF iodine method is more sensitive and less expensive and easier to perform. The frequency of chlamydia trachomatis infection in our study population appears to be age dependent with younger patients being more likely to be infected than the older patients.

• Article: Epidemiology of salmonellosis and its sensitivity in Karachi.

  ABSTRACT: Over the past five years 25,000 blood cultures were screened for septicaemia. Of these 6.7% were positive for salmonella species, the commonest being salmonella typhi accounting for 92% of total salmonella isolates. Over the years, S. typhi showed a gradual decline ranging from 96.7 to 87%. While salmonella paratyphi A has shown a gradual increase ranging from 2.5% to 11.4%. Salmonellosis peaked in the year 1990 suggesting an epidemic. The antibiotic sensitivity pattern showed a gradual increase in resistance over the years and even resistance to the new quinolones has emerged. Thus salmonellosis poses a major threat to the community and we must look into the alternative antibiotics to combat the threat.

• Article: Significance, isolation, identification and sensitivity of Branhaemella (moraxella) catarrhalis.

  ABSTRACT: In a study lasting over two years the frequency and sensitivity of moraxella catarrhalis causing respiratory tract infections were studied. Sputum samples from patients with lower respiratory tract infections were screened for moraxella catarrhalis. The organisms isolated identified and their sensitivity determined by simple methods which are practicable. The study shows that 22.4% of the infections were due to moraxella catarrhalis and 98% of the isolates were sensitive to amoxicillin-culvanalic acid (augmentin). The paper signifies the importance of reporting moraxella catarrhalis and its treatment.
