Intranasal Bacterial Therapeutics Reduce Colonization by the Respiratory Pathogen Mannheimia haemolytica in Dairy Calves

mSystems, 2020
Six Lactobacillus strains originating from the nasopharyngeal microbiota of cattle were previously characterized in vitro and identified as candidate bacterial therapeutics (BTs) for mitigating the bovine respiratory pathogen Mannheimia haemolytica.

Mannheimia haemolytica serovars associated with respiratory disease in cattle in Great Britain

BMC Veterinary Research, 2022
Background Mannheimia haemolytica is commonly associated with respiratory disease in cattle worldwide as a cause of fibrinous pneumonia, bronchopneumonia and pleuritis. M. haemolytica is further subdivided into 12 serovars, however not all are considered

The effects of inoculation of Mannheimia haemolytica into the teat of lactating ewes [PDF]

Veterinary Research, 2005
The objectives of the work described in this paper were: (i) to study the outcome of challenging ewes with Mannheimia haemolytica, at different sites of their teats, (ii) to compare the effects of two different isolates of the organism and (iii) to describe the features of the resulting lesions. Thirty-two ewes were used in the study and allocated into

Enhanced phagocytosis and complement-mediated killing of Mannheimia haemolytica serotype 1 following in-frame CMP-sialic acid synthetase (neuA) gene deletion

Microbiology Spectrum, 2023
Mannheimia haemolytica is the most significant bacterial pathogen associated with the bovine respiratory disease complex. Although sialic acid is a known virulence factor in other members of Pasteurellaceae, such as Histophilus somni and Pasteurella ...

Molecular identification and characterisation of Mannheimia haemolytica

Veterinary Microbiology
Mannheimia haemolytica is known as one of the major bacterial contributors to Bovine Respiratory Disease (BRD) syndrome. This study sought to establish a novel species-specific PCR to aid in identification of this key pathogen. As well, an existing multiplex PCR was used to determine the prevalence of serovars 1, 2 or 6 in Australia.

A Preliminary Field Study to Evaluate the Efficacy of Spiramycin and Paromomycin Against Cattle Cryptosporidiosis

Zoonoses and Public Health, EarlyView.
ABSTRACT Introduction Cryptosporidium is responsible not only for large economic losses in the livestock sector, but also for high mortality in infants and immunocompromised people all over the world. Although multiple treatments have been tested in both animals and humans, no drug has yet been found to be 100% effective.

Prebiotic Bimuno® GOS reduces illness symptoms and supports gut barrier function and immunity after intermittent exercise in the heat

Experimental Physiology, EarlyView.
Abstract Exercise in hot climates increases the risk of gastrointestinal (GI) disruption and respiratory illness. We investigated the effects of a 42 day prebiotic intervention on markers of intestinal epithelial injury, GI discomfort and immunity following football specific exercise in the heat and daily upper respiratory illness.

Susceptibility to tulathromycin in Mannheimia haemolytica isolated from feedlot cattle over a three-year period

Frontiers in Microbiology, 2013
Mannheimia haemolytica isolated from feedlot cattle were tested for tulathromycin resistance. Cattle were sampled over a three-year period, starting 12 months after approval of tulathromycin for prevention and treatment of bovine respiratory disease ...
