Sero-prevalence of hepatitis b surface antigen (hbsag) among blood donors attending ahmadu bello university teaching hospital (Abuth), Zaria, Nigeria

A study on the sero-prevalence of Hepatitis B surface Antigen among 100 blood donors attending Ahmadu Bello University Teaching Hospital Shika, Zaria, Kaduna Nigeria was carried out in June, 2008 using hepatitis B surface Antigen latex. Higher prevalence rate was observed between the age range of 30 – 39years. No prevalence was observed between 15 – 19 and 45-54years. The findings revealed high prevalence in males as compared to females (p < 0.05)

Hydrocarbon degradation by autochthonous species of Bacillus cereus and Pseudomonas aeruginosa Isolated from Kaduna Refinery Effluents

The present work was undertaken to assess the extent of crude oil degradation by Bacillus cereus and Pseudomonas aeruginosa isolated from effluents collected from Kaduna Refining and Petrochemical Company, Kaduna, Nigeria. The samples were analyzed microbiologically using standard microbiological techniques. The isolates of Bacillus cereus and Pseudomonas aeruginosa were studied to determine their biodegrading capacities on varying concentrations of crude oil as the sole carbon source using minimal medium. The bacterial growth (increase in cell number cfu/ml) was used as indices of biodegradation. The test on the degrading activity of isolates on crude oil from effluent samples revealed that Bacillus cereus and Pseudomonas aeruginosa were the potent degraders of crude oil. There was statistically significant association between time and the increase in bacterial cell numbers (P = 0.00 < 0.05). The implication of the study in relation to biodegradative activity has been discussed

Isolation and Characterization of some Hydrocarbon Utilizing bacteria from Refinery Effluents

The present work was undertaken to isolate and characterize the hydrocarbon degrading bacteria associated with effluent samples collected from Kaduna refinery and petrochemical company (KRPC). The samples were analyzed microbiologically using standard microbiological techniques. Bacillus cereus and Pseudomonas aeruginosa were successfully isolated from the refinery effluents. However, following treatment before the effluents are discharged, the levels of most parameters were brought within permissible limits. From the study, it was apparent that Bacillus cereus and Pseudomonas aeruginosa have the ability to grow and survive in refinery effluents

ANTIBIOTIC SUSCEPTIBILITY OF PYOGENIC STREPTOCOCCI IN CATFISH AND TILAPIA FROM FRESH WATER DEMONSTRATION FISH PONDS, MANDO, KADUNA

International audienceA total of three hundred (300) fish samples comprising of 150 samples each of Catfish (Clarias gariepinus Trewavas) and Tilapia (Oreochromis niloticus Teugels) were obtained from six fish ponds located in Demonstration Fish Ponds and Training Center, Mando, Kaduna. The samples were screened for pyogenic streptococci between August 2012 and January 2013. Physico-chemical parameters such as temperature, pH, conductivity, turbidity, nitrate, and biochemical oxygen demand were assessed in wet and dry seasons and the values were compared. The values obtained were further subjected to statistical analysis. The difference in values for temperature was only significant in pond 6 (p 0.05). The pH values in the six ponds were significantly different (p 0.05) in conductivity of pond 5 but ponds 1-4 showed significant difference (p 0.05) in values for nitrate, turbidity, and B.O.D across the ponds. Of the three hundred fish samples screened for pyogenic streptococci, 9 (42.2%) Streptococcus pyogenes were isolated from the body of catfish and tilapia in ponds: [P2, 2 (7.7%); P3, 3 (14.3%); P4, 2 (9.1%) and P6, 2 (11.1%)]. Streptococcus pyogenes isolates were resistant to ampiclox, amoxicillin and erythromycin but sensitive to pefloxacin, gentamycin, cotrimoxazole, cefuroxime, ceftriaxone, ciprofloxacin and streptomycin. Minimum antibiotic resistant (MAR) index was high (0.3). The implications of the findings are discussed
