BACKGROUND Avibacterium paragallinarum, the causative agent of infectious coryza, is a highly contagious respiratory acute disease of poultry, which affects commercial chickens, laying hens and broilers worldwide. METHODOLOGY In this study, we performed the whole genome sequencing, assembly and annotation of a Peruvian isolate of A. paragallinarum. Genome was sequenced in a 454 GS FLX Titaniu...
Avian Infectious coryza, a highly opportunistic respiratory tract infection caused by Avibacterium paragallinarum is now believed to be evolving as a reemerging disease of poultry birds. Albeit adoption of strong precautionary/ prophylactic measures i.e. vaccine/vaccination practice, the infection continues as complicated pattern of disease course worldwide that results in massive economic and ...
avibacterium paragallinarum is gram-negative bacteria that cause infectious coryza (ic), an acute respiratory disease of chickens. despite vaccination of layer and breeder farms of iran against ic, they are still experiencing the disease clinically and there is no knowledge of serotypes prevalence of this bacterium in this country. this study designed to determine serovar identity by molecular ...

This study designed to determine serovar identity by molecular ...
Infectious coryza (IC) is an infectious disease caused by Avibacterium (Av.) paragallinarum. IC is known to cause economic losses in the poultry industry via decreased egg production in layers. Between 2012 and 2013, Av. paragallinarum was isolated from seven chicken farms by Chungbuk National University. We identified Av. paragallinarum, the causative pathogen of IC by polymerase chain reactio...
AIM This study was carried out for the detection of Avibacterium paragallinarum from outbreaks of infectious coryza of poultry. MATERIALS AND METHODS The polymerase chain reaction (PCR) was standardized for the diagnosis of infectious coryza by using infectious coryza Killed vaccine, ventri biologicals, Pune as source of DNA of A. paragallinarum. Five outbreaks of infectious coryza from Andhr...
A molecular technique based on the restriction fragment length polymorphism of the 16S ribosomal genes amplified by a polymerase chain reaction (PCR), referred to as amplified 16S ribosomal DNA restriction analysis (ARDRA), was designed to identify 19 Avibacterium paragallinarum strains isolated from infraorbital sinus and nasal turbinate bone samples of broiler chickens, breeders, and laying h...
This study was carried out for the isolation and identification of Avibacterium paragallinarum, the etiological agent of infectious coryza (IC). Pathological changes were also investigated that occurred in organs in layer chickens obtained from some selected areas of Bangladesh. A nasal swabs (n=30) from dead chickens and four swabs from live chickens were collected aseptically. The organisms f...
