The Indian poultry market is estimated to have an annual growth rate of 8.1% as today. However, infectious diseases in pose important constraint the and development this sector our region. Among diseases, viral a serious threat industry from economic point view. Several disease outbreaks been reported by various researchers different parts country. common poultry, incidences Newcastle disease, ...

An avian infectious bronchitis virus (IBV) was detected from trachea swabs of chickens in Hubei province, China, in 2016. The complete genome of the IBV strain, CK/CH/HB/2016, was characterized and analyzed to better understand IBV epidemiology in China.

We describe the emergence of a nephropathogenic avian infectious bronchitis virus (IBV) with a novel genotype in India. The Indian IBV isolate exhibited a relatively high degree of sequence divergence with reference strains. The highest homology was observed with strain 6/82 (68%) and the least homology with strain Mex/1765/99 (34.3%).

Avian coronavirus is the causative agent of infectious bronchitis in chickens, leading to multisystemic disease that might be controlled if adequate vaccine strains are used. This paper reports the first complete genome sequence of a Brazil type of this virus (27,615 nucleotides [nt]) isolated from the kidneys of a chicken.

Throughout the world, populations of scavenger birds are declining rapidly with some populations already on the brink of extinction. Much of the current research into the factors contributing to these declines has focused on exposure to drug residues, lead, and other toxins. Despite increased monitoring of these declining populations, little is known about infectious diseases affecting scavenge...

the aim of this study was to investigate the effect of commercial herbal and chemical medicines on growth performance, serum lipids, intestinal selected bacterial population and intestinal morphology of broiler chickens. in this study, 450 day-old female broiler chickens (arian strain) were divided into 10 treatments with three replicates of 15 chicks per replicate. on day 14 of the experiment,...

Aim. To determine the difference in immune responses of harderian gland clinically healthy chickens and ones with infectious bronchitis based on content, localization morphometric estimation surface markers ?- ?-lymphocytes to differentiation index as an indicator assessing body defenses. Methods. Histological, immunohistochemical, optical, statistical. Results. The histological study determine...

an indirect enzyme–linked immunosorbent assay (elisa) was developed for screening of antibody to avian infectious bronchitis virus (ibv). antigen was prepared from whole-purified ibv massachusetts serotype (br 801 strain). optimum dilution with minimum background for antigen concentration, rabbit anti-chicken conjugate and sera in developed elisa was determined 0.1μg/ml, 1:3000 and 1:100, respe...

The viral susceptibility range of a poikilothermic cell line derived from the fathead minnow (Pimephales promelas) (FHM) to infection by a number of homoiothermic viruses representing most of the presently recognized viral groups and a member of the psittacosis-lymphogranuloma-trachoma group of agents was studied. All infectious agents, except poliovirus types 1 and 3, infectious bursal agent, ...
