| The present study was conducted on six healthy early neonatal and six prepubertal buffalo calves to study the location, gross morphology, histomorphology and histochemistry of lymphoglandular complexes in proximal colon. In very proximal part of colon of buffalo calves, an irregular oval mucosal lymphoid patch was found grossly as a proximal colon (PC) patch. Histologically, in proximal colon patch of early neonates (3-4 weeks), an extensive invasion of mucosal glands was observed towards lymphoid nodules that were present in submucosa. The structure as a whole thus formed a complex known as lymphoglandular complex (LGC). Large number of such complexes i.e., LGCs were observed in submucosa of proximal colon at this age. At some places, invasion of mucosal... |

| Faecal samples of 106 buffalo calves aged 3 to 45 days were collected sequentially, once a week, during six weeks for parasitologic examination. For bacteriologic and virologic exams, faecal samples were collected from all diarrhoeic and the same amount on non-diarrhoeic calves. Blood samples from calves were collected at 3 to 10 days of age for serum IgG determination. Eimeria spp, Strongyloides papillosus and Toxocara vitulorum were the most common parasites. E. coli, Enterobacter cloacae and Klebsiella pneumoniae were the enteropathogens most frequently found (alone or in association with other microrganisms). Heat-stable (STa) enterotoxin was detected in 5 out of 34 samples of E. coli isolated from diarrhoeic calves. Among the antimicrobials tested... |

| ABSTRACT: This study aimed to determine the virulence factors, phylogenetic groups, and the relationships between pathovars and phylogenetic groups of E. coli strains isolated from feces of buffalo calves. A total of 217 E. coli strains were obtained from feces after culture and were screened by PCR for detection of virulence factors EAST-1, enterohemolysin, Saa, CNF2, F41, F5, STa, intimin, Stx1 and Stx2. One hundred and thirty-four isolates were positive for one or more virulence factors: eighty-four from diarrheic animals, and fifty from non-diarrheic calves. The pathovars of E. coli identified in diarrheic feces were ETEC (F5+) (2/84), NTEC (16/84), STEC (20/84), EPEC (3/84), EHEC (3/84), and EAEC (EAST-1+) (33/84). Pathovars identified in... |
