Studies on role of Enterobacteriace in newlyborn friesian calves diarrhoea in Assiut and Quena governorates with special reference to their sensitivity to some antibacterial agents [electronic resource].

Includes references.

A total of 60 faecal samples were collected from newlyborn Friesian calves (age from 1 day old to 2 months) suffering from diarrhoea from different farms in Assiut and Quena Governorates. The study aimed to throw some light on the role played by Enterobacteriaeceae as a causative agent of diarrhoea in newlyborn calves. The study explained that 28 out of 60 (46.66%) calves were bacteriologically positive for Enterobacteriaeceae. 32 bacterial strains were isolated and identified biochemically as followed: 8 (25%) strains of E. coli, three of them were serotyped as 044:K74, 5 strains (15.62%) of Proteus vulgaris, 4(12.50%) of Proteus mirabilis, 4 strains (12.50%) of Morganella morgani, 2 strains (6.25%) of Enterobacter aerogenes, 3 strains (9.37%) of Enterobacter cloacae, 4 strains (12.50%) of Citrobacter diversus, 2 strains (6.52%) of Kliebseilla oxytoca. Sensitivity testing by using nine antibiotics was done against isolated strains resulting that the most of these bacterial strains were resistant. Also the public health and economic importance of that field problem was discussed.
