Mannheimia haemolytica isogenic capsular and LPS-sialylation gene deletion mutants are attenuated in a calf lung challenge model [PDF]

Microbiology Spectrum
Bovine respiratory disease complex (BRDC) is a multifactorial syndrome that involves complex interactions between environment, bacterial/viral pathogens, and the host. Mannheimia haemolytica is the most significant bacterial pathogen associated with BRDC.

Differential identification of Mannheimia haemolytica genotypes 1 and 2 using colorimetric loop-mediated isothermal amplification [PDF]

BMC Research Notes, 2023
Objective Mannheimia haemolytica is the primary bacterial pathogen associated with bovine respiratory disease complex (BRDC). While M. haemolytica has been subdivided into 12 capsular serotypes (ST), ST1, ST2 and ST6 are commonly isolated from cattle ...

Tulathromycin metaphylaxis increases nasopharyngeal isolation of multidrug resistant Mannheimia haemolytica in stocker heifers. [PDF]

Front Vet Sci, 2023
Bovine respiratory disease (BRD) is a leading cause of disease in feedlot and stocker calves with Mannheimia haemolytica (MH) as one of the most common etiologies. One of the most effective means of controlling BRD is through metaphylaxis, which involves
