Efficacy of two diagnostic tests for the detection of infectious bursal disease viruses in chicken from different types of bursal samples
Infectious Bursal Disease (IBD) is an economically important irreversible immunosuppressive disease of young birds. The present study was designed to confirm the efficacy of two common diagnostic tests for the detection of Infectious Bursal Disease Virus (IBDV) from the three types of bursal samples collected from a recent outbreak in layer and broiler chickens of Gazipur district, Bangladesh. This study compared the...
Microbiological and parasitological contamination of vegetables, water and soil in rural communities
Microbiological and parasitological contamination of vegetables, water and soil in rural communities of a municipality in the state of Bahia, Brazil, was assessed. Samples of Lactuca sativa, L., Coriandrum sativum and Solanum lycopersicum, soil, and irrigation water were analyzed between August and October, 2015. Total coliforms (TC), Escherichia coli, molds and yeasts on vegetables, soil and water, heterotrophic...
Studies on optimization of L-glutaminase production under submerged fermentation from marine Bacillus subtilis JK-79
In the current study, a marine strain Bacillus subtilis JK-79 capable of producing L-glutaminase enzyme, was analyzed for maximal L-glutaminase production. The Plackett-Burman design (PBD) was applied to determine the significant variables. Optimum conditions of the significant variables on L-glutaminase production were determined by the Central Composite Design (CCD) of response surface methodology. Maximum...
Seroprevalence of contagious bovine pleuropneumonia and contagious caprine pleuropneumonia in the Middle-Belt of Nigeria
The aim of the study was to establish the seroprevalence of contagious bovine pleuropneumonia (CBPP) and contagious caprine pleuropneumonia (CCPP) among cattle and small ruminants received at abattoirs in Ilorin, Nigeria. A total of 643 blood samples were taken from 324 cattle and 319 sheep and goats. These samples were screened for CBPP and CCPP using rapid latex agglutination tests. The majority were from the north of...
Comparative bacteriological analysis of stored borehole water sources in Oyo town, Oyo State, Nigeria
Water contamination is one of the leading causes of deaths and diseases worldwide, accounting for the deaths of more than 14,000 people daily, majority being children under 5 years old, therefore periodic monitoring of municipal water supplies are necessary. Comparative bacteriological analyses of twenty five samples of stored borehole water from five hostels in a tertiary institution in Oyo, Oyo State, was carried out...
Antimicrobial susceptibility of Flavobacteriaceae isolates from Nile Tilapia (Oreochromis niloticus) in Tanzania
This study aimed to assess antimicrobial susceptibility of members of the family Flavobacteriaceae isolated from Nile tilapia (Oreochromis niloticus). Antimicrobial susceptibility of 67 Flavobacteriaceae isolates originating mainly from ponds and Lake Victoria against 19 antimicrobial agents was determined by the broth micro dilution method. Overall, most isolates were susceptible to enrofloxacin (97%; MIC90 2 μg/ml)...
