BACKGROUND Antimicrobial usage is considered the most important factor promoting the emergence, selection and dissemination of antimicrobial-resistant microorganisms in both veterinary and human medicine. The aim of this study was to investigate the prevalence and genetic basis of tetracycline resistance in faecal Escherichia coli isolates from healthy broiler chickens and compare these data wi...

Background: Several health problems may be occurred due to consumption of mycotoxin-contaminated foods and feeds. The maize and oilseeds, as the main components of poultry feeds are susceptible to mould contamination and mycotoxin production. The aim of this study was to determine the presence of toxigenic Aspergillus spp. in poultry feeds from Ilaro, Nigeria. Methods: A total of 60 poultry fe...

Campylobacter, mainly Campylobacter jejuni and C. coli, are worldwide recognized as a major cause of bacterial food-borne gastroenteritis (World Health Organization 2010). Epidemiological studies have shown handling or eating of poultry to be significant risk factors for human infections. Campylobacter contamination can occur at all stages of a poultry meat production cycle. In summer 1999, eve...

US Department of Agriculture Food Safety and Inspection Service (FSIS) data on Salmonella enterica serotype Enteritidis in broiler chicken carcass rinses collected from 2000 through 2005 showed the annual number of isolates increased >4-fold and the proportion of establishments with Salmonella Enteritidis-positive rinses increased nearly 3-fold (test for trend, p<0.0001). The number of states w...

23 Avian leukosis virus subgroup J (ALV-J) was first isolated from meat-type 24 chickens in 1988. No field cases of ALV-J infection and tumors in layer chickens were 25 observed worldwide until 2004. However, layer flocks in China have experienced 26 outbreaks of this virus in recent years. The molecular epidemiology of ALV-J strains 27 isolated from layer flocks was investigated. The env genes...

The presence of rotavirus infection in broiler chickens (1-2 weeks old) was studied. A total of 232 faecal specimens were collected during the period from July to September 2004 and examined by polyacrylamide gel electrophoresis and silver staining (PAGE-ss) technique for the presence of rotavirus dsRNA in the Department of Medicine, Faculty of Veterinary Science, Bangladesh Agricultural Univer...

Immunocompetence of the 2001 Ross 308 broiler strain and the 1957 Athens Canadian Randombred Control (ACRBC) strain was compared when they were given diets representative of those that were being used in 1957 and 2001. Antibody response against SRBC, in vivo lymphoproliferation against Phytohemagglutinin-P (PHA-P), and inflammatory and phagocytic responses of the macrophages were measured. The ...
