Rotavirus Diarrhea Outbreaks in Arabian Thoroughbred Foals in a Stud Farm, Turkey

Abstract

SummaryIn this study, the aetiological agent of diarrhea in Arabian thoroughbred foals housed in a stud farms and it's molecular characterization were reported. Out of sampled seven foals with diarrhoea, five were detected positive by RT-PCR depending on the amplification of the VP6 gene of rotavirus. Then the aetiological agent was characterized genetically by sequence analysis of the genome segments encoding VP6, VP7, VP4 and NSP4 of rotavirus. Findings revealed that the Turkish equine rotavirus circulating within this stud farm belongs to G3 and P[12] genotype with E2 NSP4 and I6VP6. This is the first study to report the G and P genotypes of equine group A rotaviruses in Turkey.

İshal semptomlu yedi taydan sağlanan materyallerin beşinde RT-PCR tekniği ile rotavirus VP6 geni yönünden pozitiflik saptandı. Daha sonra enfeksiyona neden olan virusun VP6, VP7, VP4 ve NSP4 gen bölgelerini kodlayan gen bölgelerinin dizi analizi yapıldı. Elde edilen verilere dayanılarak söz konusu at yetiştiriciliği işletmesinde enfeksiyona neden olan ERV saha suşunun E2 NSP4 ve I6VP6 ile ilişkili G3P[12] genotipinde olduğu belirlendi. Bu çalışma, Türkiye'de atlardaki grup A rotavirusların G ve P genotiplerinin bildirildiği ilk çalışmadır.

Tek tırnaklı hayvanlarda Kırım Kongo Hemorajik Ateşi Virusu'na spesifik antikorların tespiti

“…These mentioned events are very common in rural areas, which increases the chance of being exposed to vectors like ticks. Thus, it is crucial to study infectious agents that can be detected in or transmitted by these animals, for the benefit of both animal and human health (Alkan et al 2013, Aydin et al 2020, Gilbride et al 2021Timurkan et al 2019). The reason that the seroprevalence of CCHFV infection is so high in this study is due to a number of factors, including hot weather conditions, global warming, the existence of asymptomatic animals, a continuous movement of hosts in and out of these regions, their living conditions, and the fact that horses or donkeys are kept together with other livestock.…”

Studies on Neonatal Calf Diarrhea in Kuwait

“…The Rotavirus was the major viral causes of the diarrhea recognized in neonatal calves and was originally referred to as neonatal calf diarrhea virus (Geletu et al, 2021). Globally, it was detected as the well-known the most important diarrheic pathogen for children and others mammals (Alkan, 1998). However, the vaccinations for rotavirus over a decade ago, rotavirus infections resulted in > 200,000 deaths annually, mainly in lowincome countries (Crawford et al, 2017).…”

The Molecular Characterization and Detection of Group A Rotavirus From Calves with Diarrhea in Turkish Republic of Northern Cyprus

“…Bu proteinleri kodlayan gen bölgelerinin farklılıkları esas alınarak, rotaviruslar sırasıyla G ve P genotipleri olarak sınıflandırılırlar [2] . Bugüne kadar insan ve farklı hayvan türlerinde 27 G ve 37 P genotip bildirilmiştir [3][4][5][6][7][8][9][10][11] . Sığırlarda sıklıkla bildirilen G genotipleri G6, G10 ve G8; P genotipleri ise P [1], P [5] ve P [11] [ [5][6][7][8][9] olmakla birlikte, bunların dışında G ve P genotipe sahip rotaviruslar da saptanmıştır [2,3,10,11] .…”
