garbage collectors are occupationally exposed to a variety of airborne contaminants. the main objective of this study was to evaluate the respiratory health of garbage collectors. this study was carried out in fars province, south of iran. a group of 105 garbage collectors and 93 referent subjects were investigated. a standard questionnaire was administered to both groups. furthermore, subjects...
prolonged cough occurs in a large proportion of the 2 million pilgrims who participate in the annual hajj in saudi arabia. there is no unique cause for pilgrims’ respiratory involvement, but several studies suggest a high incidence of influenza as a cause of the disease. to determine influenza vaccine efficacy against respiratory disease in pilgrims, we conducted two similar cohort studies on 5...
Infectious bovine rhinotracheitis (IBR) is worldwide disease affecting both domesticated and wild ruminants However, it has a significant economic impact on animal industry. Bovine herpes virus 1 (BoHV-1) can infect different organs of an animal. The current work aims to investigate the prevalence BoHV-l in cattle Mosul city, Iraq. In this study, 184 animals 6 months – 2 years old, were sampled...
Bovine reproductive disease attributable to bovine herpes virus-1 (BoHV-1) was first described in Germany in the 19th century, being recognised primarily as the cause of infectious vulvovaginitis and balanoposthitis until the mid-1950s when a more virulent strain of the virus (BoHV-1.1) associated with respiratory disease (infectious bovine rhinotracheitis; IBR) emerged in the western United St...
Bovine herpesvirus 1 (BHV-1) causes a variety of diseases and is globally distributed. It infects via mucosal epithelium, leading to rapid lytic replication and latent infection, primarily in sensory ganglia. Large amounts of virus can be excreted by the host on primary infection or upon recrudescence of latent infection, resulting in disease spread. The bovine immune response to BHV-1 is rapid...
Background and Aims: The role of BK and JC polyomaviruses (BKV and JCV) in the causation of respiratory disease and the natural route of transmission has not well been established. The aim of study was to determine the prevalence of BK and JC viruses in 280 respiratory samples and evaluate their contribution to respiratory disease. Materials and Methods: PCR was used to screen specimens for BK...
Abstract Cattle feed yards routinely track and collect data for individual calves throughout the feeding period. Using such operational from nine U.S. years 2016–2019, we evaluated scalability economic viability of using machine learning classifier predicted mortality as a culling decision aid. The expected change in net return per head when predictions aid compared to status quo protocol havin...
