Pathogenecity of aspergillus fumigatus in young broiler chicks

A total of 450 out of 5000 chicks of two-old with a history of repiratory symptoms followed by death 1 to 4 days from onset of signs. From which sixteen of freshly dead chicks were examined at postmortem and mycologically. In addition, experimental infection with isolated Aspergillus fumigatus from naturally infected chicks via contaminated litter were carried out. The clinical findings were recorded including respiratory signs, droopiness, anorexia, watery diarrhea of offensive odour and lack of equilibrium. Also, 0, one, seven, one, two, four and six chicks died on 1, 2, 3, 4, 5, 6, and 7 days post infection respectively. Post mortem examination of freshly dead experimentally infected chicks revealed pneumonia, white yellowish caseous nodules on the lungs and air sac. Mycologically, the cases were diagnosed as infection with Aspergillus fumigatus

Air and water as sources of bacterial contamination of beef carcasses

Specimens swabs [75] were obtained from the surface of cattle carcasses after evisceration. Also 50 samples from each of air and water were collected from different location of slaughter halls at Alexandria abattoirs. Total bacterial count, enterobacteriaceas, coliform [MPN], enterococci count [MPN] and staphylococcus aureus were carried out in the examined samples. In addition, the obtained results revealed the isolation of various kinds of bacteria. The role of air and water as a source for bacterial contamination of beef carcasses as well as the public hazard of each isolate were discussed
