The hypothalamic-pituitary-thyroid axis is suppressed by pro-inflammatory mediators in systemic disease, which affects the thyroid hormone level. Canine parvovirus is one of the important infectious diseases which causes profound morbidity as well as mortality in dogs. It is found that canine parvovirus infection can result in non-thyroidal sickness syndrome. The relation between thyroid pathology and canine parvovirus infection will pave the way for therapeutic and preventive measures for this infectious disease. This study was conducted on 61 dog carcasses brought to the Department of Veterinary Pathology, College of Veterinary and Animal Sciences, Pookode during one year period. Among 61 cases, nine were found to be positive for canine parvovirus which constitutes an incidence of 14.75 per cent. Analysis of gross and histopathological lesions in canine parvovirus positive cases was the goal of this investigation. The gross lesions observed were paleness and nodular growth and histopathological lesions encountered were lymphocytic thyroiditis, colloidal goiter, c cell hyperplasia, severe fibrotic changes and neoplastic lesions. Further research is required to understand the pathophysiology of the euthyroid sick syndrome in canine parvoviral infection.
Testicular atrophy is a condition impairing the reproductive health of male chicken. Lithiasis or stone formation in testicles or epididymis adds to the gravity of the problem. The present study describes a case of unilateral testicular atrophy with epididymal lithiasis in a one-year-old male Gramasree cock. The carcass, was brought to the Department of Veterinary Pathology, College of Veterinary and Animal Sciences, Pookode, for postmortem examination. The lesions were recorded and tissues for histopathology were collected in 10% neutral buffered formalin, sectioned, and stained using routine hematoxylin and eosin staining procedure. Grossly, there was diffused congestion of the testicular tunic with atrophy of right testis. The epididymis was congested with multifocal white spots. Histologically, seminiferous tubules were severely degenerated. The efferent ductules of epididymis were dilated with basophilic amorphous and granular liths in multiple locations. Sperm stasis was evident in a few ductules and rete testes. The lith formation might have caused sperm stasis and degeneration and atrophy of the testis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
