Background Rapid etiological diagnosis has a very important role in the clinical management of respiratory viral infections. Using a multianalyte point-of-care detection system, based on a fully automated immunoassay method, we can detect 8 respiratory viruses (influenza A and B viruses, parainfluenza 1, 2 and 3 viruses, respiratory syncytial virus, human metapneumovirus and adenovirus) and the...

Infection of cattle by bovine herpesvirus type 1 (BHV-1) can lead to upper respiratory tract disorders, conjunctivitis, genital disorders and immune suppression. BHV-1-induced immune suppression initiates bovine respiratory disease complex (BRDC), which costs the US cattle industry approximately 3 billion dollars annually. BHV-1 encodes at least three proteins that can inhibit specific arms of ...

In general, members of the Alphaherpesvirinae use the epithelium of the upper respiratory and/or genital tract as a preferential site for primary replication. Bovine herpesvirus type 1 (BoHV-1) may replicate at both sites and cause two major clinical entities designated as infectious bovine rhinotracheitis (IBR) and infectious pustular vulvovaginitis/balanoposthitis (IPV/IPB) in cattle. It has ...

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...

BACKGROUND Viral infections play a significant role as cause of Acute Respiratory Infections (ARIs) and exacerbations of chronic diseases. ARIs are now the leading cause of mortality in children worldwide, especially in developing countries. Recently human rhinovirus (HRV) infection has been emerged as an important cause of pneumonia and asthma exacerbation. OBJECTIVES To determine the role o...

Feline Viral Upper Respiratory Tract Disease Feline viral upper respiratory tract disease is typified by signs of rhinosinusitis, conjunctivitis, lacrimation, salivation, and/or oral ulcerations. The principal causative agents are feline herpesvirus type 1 (FHV-1 ) and feline calicivirus (FCV). These viruses are host-specific and pose no known human risk. Other infectious agents (e.g. Bordetell...

Infectious bronchitis, Newcastle disease, infectious laryngotracheitis, avian influenza, and pneumovirus are the viruses that more frequently affect the respiratory tract of chickens, because of their tendency to change its antigenic properties Infectious laryngotracheitis has appeared in the broiler industry as a serious disease. Newcastle is a highly contagious, disease in which all birds in ...

Pneumonia is a leading cause of loss to the sheep and cattle industry throughout the world. Mannheimia (Pasteurella) haemolytica is one of the most important respiratory pathogens of domestic ruminants and causes serious outbreaks of acute pneumonia in neonatal, weaned and growing lambs, calves, and goats. M. haemolytica is also an important cause of pneumonia in adult animals. Transportation, ...
