A rare case of cerebral hydatidosis caused by a G1 genotype of Echinococcus granulosus in a cow from Iran

Abstract

Hydatidosis is a medically and veterinary important parasitic disease that is endemic in many parts of the world. Unilocular hydatid cysts may develop in almost any part of the body. Up to 70% of hydatid cysts are located in the liver, followed by 25% in the lungs. Cerebral hydatidosis is an uncommon manifestation of the disease, occurring in less than 1/1000 infected hosts, yet diagnosis does pose a problem. We have reported an exceptionally rare case of cerebral hydatidosis in cattle. This is the first report to describe the characteristic pathological features of the cerebral hydatidosis in cattle caused by the G1 genotype of Echinococcus granulosus. Genotypic analysis was performed on a hydatid cyst from a cow originating from southern Iran, based on the sequence analysis of the cox1 mitochondrial gene.

The effect of cystic echinococcosis (hydatid disease) on carcase weight in cattle in eastern Australia

“…Although cattle are considered accidental hosts and infection is generally subclinical, hydatid cysts are frequently found in the viscera at processing 1 , 3 , where they are primarily reported in the liver and lungs 3 , 4 . Cysts are less frequently reported in the heart, kidney, spleen 1 , 3 , 5 and occasionally the brain and skeletal muscle 1 , 6 .…”

The effect of echinococcosis (hydatid disease) on carcase weight in cattle

“…Although cattle are considered accidental hosts and infection is generally subclinical, hydatid cysts are frequently found in the viscera at processing (Baldock et al, 1985;, where they are primarily reported in the liver and lungs (Banks et al, 2006;. Cysts are less frequently reported in the heart, kidney, spleen (Baldock et al, 1985;Regassa et al, 2010; and occasionally the brain and skeletal muscle (Baldock et al, 1985;Moazeni et al, 2015).…”
