The prevalence of bovine respiratory disease complex (BRDC) has remained unchanged for decades despite efforts to suppress the disease through prevention programs aimed at vaccination and metaphylaxis. An additional approach that focuses on host response to infection by the pathogens responsible for BRDC, through the selection of animals that are less susceptible to the disease, has been undert...

conclusions to reduce the impacts of particulate matter on health status of people in ilam, necessary training by health systems should be conducted for people, especially those with chronic lung and heart diseases, the elderly and children to reduce their activities on the dusty days. methods pm10 data was taken from the ilam environmental protection agency. the annual morbidity including hosp...

Susceptibility to bovine respiratory disease (BRD) is multi-factorial and is influenced by stress in conjunction with infection by both bacterial and viral pathogens. While vaccination is broadly used in an effort to prevent BRD, it is far from being fully protective and cases diagnosed from a combination of observed clinical signs without any attempt at identifying the causal pathogens are usu...

83 gram-negative bacterial pathogens, resulting in increased drug potency. Tulathromycin has shown high efficacy against the common bacterial causes of respiratory disease in cattle and swine: It is rapidly released from the injection site, promoting early achievement of inhibitory concentrations in lung tissue. Furthermore, extensive tissue penetration and slow release from tissue provide exte...

Bovine herpesvirus type 1 (BoHV-1) causes respiratory and reproductive disorders in cattle. Recently, bovine herpesvirus type 5 (BoHV-5) and bovine herpesvirus type 4 (BoHV-4) have been identified to be associated with genital disease. In this study, the presence of the genome of BoHV-1, BoHV-4 and BoHV-5 in bovine semen of Argentinean and international origin was analyzed by PCR assays. The mo...
