Potential involvement of gelatinases and their inhibitors in Mannheimia haemolytica pneumonia in cattle.
Mannheimia haemolytica infection of the lower respiratory tract of cattle results in a bronchofibrinous pneumonia characterized by massive cellular influx and lung tissue remodeling and scarring. Since altered levels of gelatinases and their inhibitors have been detected in a variety of inflammatory conditions and are associated with tissue remodeling, we examined the presence of gelatinases in...
متن کاملPhenotypic characterisation of Australian sheep and cattle isolates of Mannheimia haemolytica, Mannheimia granulomatis and Mannheimia varigena.
OBJECTIVE To perform a comprehensive phenotypic characterisation of 35 isolates of bacteria previously identified as haemolytic Pasteurella-Actinobacillus and obtained from cattle and sheep. DESIGN The 35 isolates that had been obtained from Australian animals, 30 from cattle and five from sheep, were compared with reference strains of the five recognised species of the genus Mannheimia--M. h...
متن کاملBacteriological and serological studies on Mannheimia haemolytica infection in cattle slaughtered at Ahvaz (southwestern Iran) abattoir
In order to investigate the prevalence of Mannheimia haemolytica infection in cattle, nasal andnasopharyngeal swabs and blood samples were obtained from 250 cattle after slaughter at Ahvaz(southwestern Iran) abattoir. Nasal and nasopharyngeal swabs were cultured on blood agar and incubated at37°C for 24-48 h. The suspected bacterial cultures were processed for isolation of M. haemolytica follow...
متن کاملAntimicrobial susceptibility testing of Mannheimia haemolytica and Pasteurella multocida isolated from calves with dairy calf pneumonia
This study evaluated the nasopharyngeal microbial flora and antimicrobial susceptibility patterns of the one hundred and thirty Holstein calves with dairy calf pneumonia from dairy farms of Mashhad Suburb between September 2002 and August 2003 . The most common micro-organisms isolated were Pasteurella multocida 80 (61.54%), Mannheimia haemolytica 41 (31.54%), Bacillus sp. 15 (11.54%), Staphy...
متن کاملBacteriological and therapeutic studies on Mannheimia haemolytica and Pasteurella multocida in bovine respiratory disease at dairy cattle farms in Tehran
In this study, we performed a bacteriological investigation on bovine respiratory infections. Additionally, the study evaluates the efficacy of florfenicol 30 µg produced by Rooyan Darou Company (test group) as compared to a similar drug produced by Aboraihan Company (control group). Sampling was carried out on 30 calves at two farms with 30-55% incidence rate of respiratory disorders. Nasophar...
