Respiratory infection in bovine is most important cause of morbidity and mortality and also leads to economic losses of farmers in terms of low productivity of affected animals. The infection mostly observed in viral bacterial interaction with other stress factors plays key role in development of sub clinical to clinical disease(s). It is generally accepted that the viruses are the primary path...

Introduction Bibersteinia trehalosi has been associated with respiratory disease in ruminants particularly in wild and domestic sheep. Recently, there has been an increased interest in B. trehalosi isolates obtained from diagnostic samples from bovine respiratory disease cases. This study evaluated the role of B. trehalosi in the bovine respiratory disease complex using an intra-tracheal inocul...

BHV-1 is an important pathogen of cattle. Because of its ability to induce immune suppression, BHV-1 is an important agent in the multifactorial disorder, bovine respiratory disease complex (BRDC). BHV-1 encodes several proteins that inhibit various arms of the immune system suggesting that these proteins are important in the development of BRDC.

Multiple factors have been identified as elements of the respiratory disease complex in Rocky Mountain bighorn sheep (Ovis canadensis canadensis). We hypothesized that differences in health factors and Pasteurellaceae in the upper respiratory tracts could exist between populations of bighorn sheep with and without histories of pneumonic epizootics. We evaluated bighorn sheep in the Big Creek ar...

background: many epidemiological studies reported significant associations between air pollution and respiratory hos­pital admissions. proximity of industries to the residential areas may have considerable impacts on air quality and sub­sequently public health. this paper describes the indirect impacts of closing a large steel industry, broken hill proprie­tary (bhp), in the lower hunter region...

In this study, we determined the prevalence of bovine respiratory disease (BRD)-associated viral and bacterial pathogens in cattle and characterized the genetic profiles, antimicrobial susceptibilities, and nature of antimicrobial resistance determinants in collected bacteria. Nasopharyngeal swab and lung tissue samples from 68 BRD mortalities in Alberta, Canada (n = 42), Texas (n = 6), and Neb...

Cattle farming is an ancient practice, with roots in the early Neolithic era that has retained a major status food industry, global beef market revenue amounting to $385.7B (as of 2018). Hence, cattle maintenance essential for catering nutritional requirements modern civilization. This extensive review aims provide holistic overview microbiome, analyzing native microbial composition within resp...

This work develops a loop-mediated isothermal amplification (LAMP) assay that detects the presence of bacterial pathogens (Pasteurella multocida, Mannheimia haemolytica, and Histophilus somni) for bovine respiratory disease complex (BRD) in crude nasal samples. Diagnosing BRD involves physical examination cattle expressing symptoms linked to disease. Unfortunately, these are not unique alone do...
