Antimicrobial 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 کاملCombinations of macrolide resistance determinants in field isolates of Mannheimia haemolytica and Pasteurella multocida.
Respiratory tract infections in cattle are commonly associated with the bacterial pathogens Mannheimia haemolytica and Pasteurella multocida. These infections can generally be successfully treated in the field with one of several groups of antibiotics, including macrolides. A few recent isolates of these species exhibit resistance to veterinary macrolides with phenotypes that fall into three di...
متن کاملMacrolide resistance conferred by rRNA mutations in field isolates of Mannheimia haemolytica and Pasteurella multocida.
OBJECTIVES To determine how resistance to macrolides is conferred in field isolates of Pasteurella multocida and Mannheimia haemolytica that lack previously identified resistance determinants for rRNA methylation, efflux and macrolide-modifying enzymes. METHODS Isolates of P. multocida and M. haemolytica identified as being highly resistant (MICs >64 mg/L) to the macrolides erythromycin, gami...
متن کاملProximity-dependent inhibition of growth of Mannheimia haemolytica by Pasteurella multocida.
Mannheimia haemolytica, Pasteurella multocida, and Bibersteinia trehalosi have been identified in the lungs of pneumonic bighorn sheep (BHS; Ovis canadensis). Of these pathogens, M. haemolytica has been shown to consistently cause fatal pneumonia in BHS under experimental conditions. However, M. haemolytica has been isolated by culture less frequently than the other bacteria. We hypothesized th...
