Bovine viral diarrhea virus (BVDV) is a diverse group of viruses responsible for causing disease in ruminants worldwide. Since the first description of BVDV as a cause of disease, it has undergone surges and lulls in importance. Epizootics of disease caused by BVDV are described. Although naming of the virus and illness implies gastrointestinal disease in cattle, BVDV is a pathogen that affects...

Pulmonary infectious diseases afflict millions of people annually, with significant morbidity and mortality associated with bacterial, viral and fungal infections. Patients with respiratory disease are particularly susceptible to infection, where respiratory infections are associated with exacerbations of disease and worsening lung function. The impact of infectious diseases and the growing thr...

The bovine and human respiratory syncytial viruses cause severe lower respiratory tract infections. Effective vaccines against the respiratory syncytial viruses have been lacking since vaccine failures in the 1960s and 1970s. In this report, we describe a bovine respiratory syncytial virus (bRSV) challenge model in which both classical bRSV respiratory infection and vaccine-enhanced immune path...

BACKGROUND The prevention of bovine respiratory disease complex (BRD) in beef cattle is important to maintaining health and productivity of calves in feeding operations. OBJECTIVE Determine whether BRD bacterial and viral pathogens are susceptible to the lactoperoxidase/hydrogen peroxide/iodide (LPO/H2 O2 /I- ) system in vitro and to determine whether the oral administration of sodium iodide ...

Contagious bovine pleuropneumonia (CBPP) is a severe disease caused by Mycoplasma mycoides subsp. mycoides (Mmm). Knowledge on CBPP pathogenesis is fragmented and hampered by the limited availability of laboratory animal and in vitro models of investigation. The purpose of the present study is to assess respiratory explants as useful tools to study the early stages of CBPP. Explants were obtain...

three subheadings including treatment, prevention and control and diagnosis methods got the most priorities, respectively. although about half of the priorities are related to two subheadings including treatment and diagnosis methods, research priorities of prevention and control methods (22% of all priorities) indicate the importance of prevention for clinicians who gave scores to the titles. ...

Bovine respiratory disease complex, remains an important economic disease affecting food animals in North America and worldwide, despite improvements in production management, approval of new medications and continuing research in this area. Production losses due to pneumonia remain nearly constant, adding millions of dollars in industry costs annually. Bovine respiratory disease complex result...

Human adenoviruses are a common cause of diseases. While epidemic diseases caused by adenoviruses were observed throughout the first half of the 20th century, the viruses were first noted in explant cultures of human adenoidal surgical specimens in 1953; this finding, plus the observation of their apparent general affinity for lymphatic tissue, led to naming designation [1, 2]. More than 50 ser...

Currently, the whole world is facing a life-threatening novel coronavirus 2019 (COVID-19) pandemic. Natural products are well-known for their potential role against viral disease, and some anti-viral agents have been developed to combat these diseases. Herein, authors investigated possible effects of this Holy plant Nigella sativaL. (NS), coronavirus, using evidence-based mechanistic approaches...

more than one percent of the labor force in each country consists of welders exposed to various damages caused by welding. the number of studies conducted in this field is low, especially in iran. in this paper, we tried to discover any temporary and reversible obstructive effect of welding fumes on the respiratory systems of welders. in this cross-sectional study, peak expiratory flow rates an...
