Pathology and molecular characterization of chicken infectious anemia virus and antigen prediction.

The present study investigated five poultry flocks (size 142-600 birds) suspected of chicken infectious anemia (CIA) from Maharashtra, India. The necropsy of dead birds revealed severe atrophy of the thymus, gelatinization of bone marrow, subcutaneous hemorrhages, growth impairment, and severe anemia. Specific PCR targeting, 1390 bp fragment of the CIAV, VP1 gene was used in this study.

Molecular detection and patho-morphological study of enteric pathotypes in diarrheic neonatal calves.

To understand the pathology of natural cases of pathotypes infection in bovine calves, 45 cases of bovine calves, below one month of age, died due to enteritis were studied. Total seventeen cases (37.77%) turned positive for different pathotypes of by RT-PCR.

Patho-morphological and immunohistochemical diagnosis of fibrous tissue pulmonary hamartoma in young buffaloes.

Hamartoma is a developmental disorder characterized by the presence of well-differentiated tissue, of multiple types, in excess at its normal location. The present study describes a fibrous tissue pulmonary hamartoma in two buffaloes. Grossly, there were large pale white masses present on the left diaphragmatic lobe in both cases.

Immunofluorescence and molecular diagnosis of bovine respiratory syncytial virus and bovine parainfluenza virus in the naturally infected young cattle and buffaloes from India.

Pneumonia in bovines is a multifactorial disease manifestation leading to heavy economic losses. Infections of bovine respiratory syncytial virus (BRSV) and bovine parainfluenza virus-3 (BPI-3) are among the important contributing factors for the development of pneumonia in young animals. These viral agents either primarily cause pneumonia or predispose animals to the development of pneumonia.

Immunohistochemical and molecular detection of natural cases of bovine rotavirus and coronavirus infection causing enteritis in dairy calves.

Bovine rotavirus (BRoV) and bovine coronavirus (BCoV) are major enteric viral pathogens responsible for calve diarrhoea. They are widespread both in dairy and beef cattle throughout the world and causing huge economic losses. The diagnosis of these agents is very difficult due to non-specific nature of lesions and the involvement of some intrinsic and extrinsic risk factors.

Comparative investigations of infectious runting and stunting syndrome in vaccinated breeder chicks by inactivated reovirus and chicks from non-vaccinated breeders.

Reoviruses are important pathogens responsible for poor growth performance and silent losses in the poultry industry. They are associated with many disease and syndromes such as malabsorption (runting and stunting syndrome), respiratory diseases and immunosuppression. Broiler birds are most susceptible to viral infections during the early post hatching period.

Molecular characterization of chicken anemia virus outbreaks in Nagpur province, India from 2012 to 2015.

Chicken anemia virus (CAV) is one of the important poultry pathogen. CAV infection can cause immunosuppression, aggravation of co-infections, vaccination failures and mortality. We are reporting the CAV outbreaks from the Nagpur province of India, between the years 2012-2015.
