Prevalence of subclinical coccidiosis in river buffalo calves of southwest of Iran

Abstract

Despite the importance of buffalo farming in Iran, little is known in this country about the abundance and distribution of Eimeria spp. in the animal species. The present study was designed to investigate the prevalence and species characterization of Eimeria oocysts in river buffalo calves of Khuzestan province, southwest of Iran. Of the total 108 fecal samples examined for Eimeria, 108 (100%) were found infected with 11 species of the parasite. Among the identified species of Eimeria, E. bovis was found to be the predominant etiological agent (76.85%), followed in order by E. canadensis (62.96%), E. zuernii (47.2%), E. ellipsoidalis (26.85%), E. subspherica (25.92%), E. brasiliensis (19.4%), E. auburnensis (18.51%), E. alabamensis (14.81%), E. pellita (11.1%), E. illinoisensis (5.5%) and E. bukidnonensis (2.7%). In most calves multiple infections with three species were present. While, 20.7% of calves showed heavy infection, 50.4 and 24.8% of calves showed weak and moderate infection, respectively. There was no significant difference in the OPG values between the calves of different localities. There was also no significant difference between the prevalence rate of infection in males and females. A total of 16.6% of all faecal samples were found to be diarrheic. A highly significant relationship could be identified between the occurrence of diarrhea and the level of E. bovis and E. zuernii oocysts excretion. Considering the pervasive occurrence and negative effects of the infection on the health condition and the growth performance of buffalo calves, infections should receive increased attention by both farmers and veterinarians.

Eimeria species in dairy and beef cattle of different ages in Goiás state, Brazil

“…identified in different regions occurred even though E. subspherica, E. pellita and E. bukidnonensis were not diagnosed in the Nelore cattle examined in the present study. In studies conducted in Brazil (REBOUÇAS et al, 1994;ALMEIDA et al, 2011;BRUHN et al, 2011;RODRIGUES, 2014) and other regions of the world (CHIBUNDA et al, 1997;CICEK et al, 2007;REHMAN et al, 2011;BANGOURA et al, 2012;BAHRAMI & ALBORZI, 2013;LUCAS et al, 2014), Eimeria bovis was the most frequent species. These results led these researchers to describe E. bovis as the most frequent species worldwide.…”

Molecular Typing of Eimeria ahsata and E. crandallis Isolated From Slaughterhouse Wastewater

“…These parasites invade epithelial tissues of the intestine, causing severe damage in the host and result in significant economic losses ( 2 ). At least twelve species of bovine Eimeria , ten species of ovine Eimeria and nine species of caprine Eimeria occur in Iran ( 3 - 5 ). Eimeria ahsata and E. crandallis are two of a group of ovine coccidia of what might be called the arloingi type ( 6 ).…”

Subclinical Bovine Coccidiosis in Al -Baha Area, Saudi Arabia

“…Bovine coccidiosis is considered to be of considerable importance for the productivity and health of cattle. Coccidiosis in cattle commonly occurs as subclinical, without typical signs of the disease but may though causes great economic losses due to damage in intestine lining, resulting in malabsorption [1]. Infected calves are also more susceptible to secondary diseases, such as pneumonia, bacterial enteritis and viral infections [1][2][3].…”
