The present study was carried out for the assessment and detecting of the Escherichia coli and Staphylococcus aureus bacteriophages and their bacterial host's proteins includes visual inspection and comparison of their molecular weight mass. Systematic methods that use microorganisms (viruses and bacteria) to test samples from the local sewage wate...
Article
The research aimed to study the diastatic power (PD) of sorghum malt , to purify the α and β-amylase s and to characterize these enzymes. In this study the amylolytic activity initiated during the germination of sorghum was determined. Fourth day of germination of sorghum grains showed the highest of the amount of Diastatic Power (DP) (62.0 IOB), n...
Article
This study aimed to investigate the hygienic conditions of air at delivery and nursing rooms at some hospitals located in Khartoum district Sudan. Out of seventy-nine randomly collected air samples from delivery rooms at the four largest hospitals (Khartoum Teaching Hospital, Al Ribat Hospital, Ahmed Fadul Hospital and Omdurman Maternity Hospital),...
Article
This study was aimed to evaluate the microbial quality of drinking water distributed at Khartoum state- the capital of the Sudan. Water distributed at piped system was investigated using two different standard methods (MPN and chromogenic media- based techniques), 47.5-90% showed positive isolation of bacteria. The results revealed isolation of fae...

Enterobacteriaceae were isolated from gills, skin, muscles and the intestine of 83 out of 150 (55%) randomly collected fishes, the most dominants isolates were E. coli, Citrobacter spp, Enteriobacter spp and Klebsiella spp. This together with the highly pathogenic Enterobacteriaceae including Salmonella spp and Shigella spp. Proteus spp, and Alkleg...
Article
The petroleum ether, ethanol and aqueous extracts of the Tamarindus indica and Adansonia digitata were screened for the presence of possible anti-microbial activity using the cup plate agar diffusion method. They were tested against Escherichia coli that isolated from urine and water sources. Each extract was used in concentration of 100, 75, 50 an...

The aim of present study was to investigate the seroprevalence of brucellosis among cattle and cattle-owners at selected area of Khartoum state. This research was carried out in Gubul Awliaa area farms, out of 175 unvaccinated cattle 84 (48%) were shown positive agglutination reaction towards Br. melitensis while 44 (26.4%) showed positive reaction...
Article
The antimicrobial activity of three types of Bees honey (Sidir, Sunflower and Sunut) were examined against (Staphylococcus aureus, Escherichia coli, Klebsiella aerugenes, Pseudomonas aeruginosa and Candida albicans) at concentration 100, 75, 50 and 25%. Sidir honey showed antimicrobial activity against Staphylococcus aureus, Klebsiella aerogenes, P...

The integration of crop and livestock production in the Sudan is necessary to maximize economic returns, provide more diversification, reduce cost of production, maximize efficiency of resource use, use crop residues efficiently, improve soil physical properties by use of manure, and improve food supply and nutritional status. Farming systems in th...
Article
Petroleum ether, methanol and water extracts of Psidium guajava leaves were tested to determine their possible antimicrobial activity against Gram-positive (Staphylococcus aureus and Bacillus subtilis) and Gram-negative bacteria (E. coli and Salmonella typhi) and fungi (Aspergillus niger and Candida albicans). Each extract was used in concentration...
Article
One hunderd and sixty three 14-82 year old women hospitalized at the Departments of Surgery and Medicine, Khartoum Teaching Hospital and co-patients women, nurses and workers were investigated for urinary tract infection. The number of women who had significant bacteriuria (10 5) was 94; 53 of them were symptomatic while 41 were asymptomatic. From...

This study was done to investigate the presence of Salmonellae in Sudanese white cheese at Khartoum State. Two hundreds cheese samples were purchased from restaurants, retailers and shops, distributed in Khartoum and Omdurman. The isolated Salmonella paratyphi (6%) were equally identified as paratyphi A and paratyphi B. The sensitivity to antibioti...
