Background: Poultry enteritis is an important multifactorial disease. Chicken Astrovirus (CAstV) usually associated with enteritis. The aim of this study was to investigate the occurrence of CAstV in poultry enteritis cases, its molecular characterization, phylogenetic analysis and gross and microscopic examination of intestine and liver specimen affected with CAstV. Methods: Total 604 dead poultry birds from commercial poultry farms affected with enteritis were examined for presence of CAstV. Intestinal samples of four birds were pooled to make one biological sample. CAstV was detected by reverse transcriptase PCR (RT-PCR) using ORF-1b gene specific primers. Molecular characterization was carried out by partial gene sequencing. Result: CAstV was detected in 20.52% (31/151) of samples. Highest prevalence (49.29%) was observed in 0-1 week old chicks. The partial molecular characterization revealed high similarity of the nucleotide sequence from India (97% to 93%) and from USA, Brazil, Poland and Korea (94 to 92%). Further similarity of amino acid sequences of CAstV from India (100% to 98%) and from USA, Brazil, Poland and Korea (98 to 97%) was observed. Histopathological examination revealed villous atrophy, congestion and atrophic cystic glands in sub-mucosa of intestine. Further severe congestion and hemorrhages along with infiltration of inflammatory cells in liver parenchyma was observed.

A Prospective Study

Background: Purpose of autopsy is to learn the truth about the person’s health during and how the person died. Thus, autopsy study provides valuable information about the disease. The main aim of the study was to know the spectrum of morbid anatomical changes in liver autopsy.Methods: A prospective study was carried out on 100 liver specimens of autopsy cases comprising of 37 cases of roadside accidents, 17 of poisoning, 13 of burns, 10 of chronic illness, 7 each of hanging and head injury, 4 of myocardial infarction and 5 of death due to miscellaneous causes. Representative microsections of liver were evaluated for histopathological parameters like congestion, ballooning degeneration, hepatocellular necrosis, sinusoidal dilation, fatty change, bile stasis, fibrosis, lobular inflammation and portal inflammation.Results: Out of total 100 cases, 77 were males and 23 females. Male to female ratio was 3.34:1. Hepatomegaly was seen in 15% of cases. Chronic venous congestion was the main histopathological diagnosis seen in 61% of the cases followed by chronic hepatitis in 12%, normal liver histology in 9%, hepatic steatosis and cirrhosis in 6%, granulomatous hepatitis in 2%, and sinusoidal congestion, portal triaditis and secondary neoplasm in 1% each.Conclusions: Chronic venous congestion, chronic hepatitis, cirrhosis and hepatic steatosis were the common liver diseases identified. Autopsy study is useful to monitor the cause of death and to plan medical strategy. Histopathological examination of the liver is specialized learning tool to study the various diseases of liver which is a great value in improving the diagnosis.
