Genetic diversity, frequency and concurrent infections of picobirnaviruses in diarrhoeic calves in Turkey.

Calf diarrhoea is one of the major problems in cattle farming with high morbidity and mortality in herds. Two enteric viruses, bovine rotavirus (BRV) and bovine coronavirus (BCoV), are the leading cause of gastroenteritis in young calves, whereas picobirnaviruses (PBVs) are often associated with diarrhoea. In the present study, the faecal specimens of 127 diarrhoeic bovines (less than 1-month-old) were employed to investigate the infection frequencies of these three pathogens.

Determination of VP2 sequence-based virulence motifs and phylogenetic analysis of domestic Turkish IPNV ısolates.

Infectious pancreatic necrosis (IPN) is a highly contagious disease of young salmonid fish and is one of the most severe economic diseases in aquaculture. In Turkey, an increase in infectious pancreatic necrosis virus (IPNV) outbreaks in freshwater rainbow trout have been reported in recent years. This study aimed to analyze the VP2 gene from recent IPNV isolates from Turkey to determine whether there are epidemiological links between IPNV isolates from rainbow trout (Oncorhynchus mykiss; 62) and sea bass (Dicentrarchus labrax; 1), wild turbot (Scophthalmus maximus; 1) and the environment in order to investigate potential wild and farmed fish interactions.

Inactivated infectious pancreatic necrosis virus (IPNV) vaccine and E.coli-expressed recombinant IPNV-VP2 subunit vaccine afford protection against IPNV challenge in rainbow trout.

Infectious pancreatic necrosis (IPN) is a highly contagious disease causing high mortality in juvenile trouts. Since there is no effective way to treatment against IPNV, early diagnosis and prevention play an important role in combating the disease. The different types of IPNV vaccines (inactive, live, recombinant, DNA, etc) have been produced from local isolates and have been used in developed countries.

Molecular analysis of goose parvovirus field strains from a Derzsy's disease outbreak reveals local European-associated variants.

Since its first recognition in the early 1960s, Derzsy's disease has caused significant economic losses in the goose meat industry through the world. Today, Derzsy's disease still maintains its importance for small-scale waterfowl farming, despite not having a significant impact on public health. In the present study, we investigated the distribution of goose parvovirus (GPV) and its potential variants from a 2019 outbreak in Turkey.

GENETIC DIVERSITY of OVINE HERPESVIRUS 2 STRAINS OBTAINED FROM MALIGNANT CATARRHAL FEVER CASES in EASTERN TURKEY.

Malignant Catarrhal Fever (MCF) is a generalized, definitive lethal disease affecting the epithelial and lymphoid tissues of the respiratory and digestive tract, mainly cattle and some wild ruminants such as deer, buffalo or antelope. The sheep-related form of MCF is known to be present in Turkey and is caused by ovine herpesvirus 2 (OvHV-2). The aim of this study was to reveal the genetic diversity of OvHV-2 strains obtained from MCF cases in Eastern Turkey where the livestock industry has an important impact on economic activities.

Detection and first molecular characterisation of three picornaviruses from diarrhoeic calves in Turkey.

The involvement of picornaviruses in calf diarrhoea was evaluated by the analysis of 127 faecal samples collected from diarrhoeic calves during 2014-2016. Virus detections were carried out by PCR using generic or specific primer pairs. One-third of the faecal samples (33.

Detection and Molecular Analysis of Bovine Enteric Norovirus and Nebovirus in Turkey.

Introduction: Bovine Norovirus (BoNeV) which has been confirmed in Asia, America, and Europe, seems to be distributed worldwide, even though only reported from a number of countries. Bovine noroviruses are predominantly detected in diarrhoeic animals rather than neboviruses. The study reveals the importance of noro- and neboviruses in early age diarrhoea of calves.

The diagnostic value of two commercially available human cTnI assays in goat kids with myocarditis.

Background: Cardiac troponin I (cTnI) is a peripheral blood marker for myocardial damage. Because of the unavailability of goat-specific cTnI assays human cTnI assays may be validated for detection of myocarditis in goat kids.

Objectives: The purpose of the study was to evaluate 2 commercially available human cTnI assays in goat kids with myocardial damage, and to determine the cTnI expression in cardiac muscle.

Detection of bovine torovirus in fecal specimens from calves with diarrhea in Turkey.

Bovine torovirus (BToV), a member of the family Coronaviridae, is an established gastrointestinal infectious agent in cattle. In this study, we performed a survey to detect BToV in Turkey between 2009 and 2011 using 235 fecal samples from neonatal calves with diarrhea that were analyzed by the nested reverse transcription (RT) PCR method using primers located in the consensus sequences of the BToV membrane (M) gene. The BToV M gene was detected in 4.

Genotyping and pathogenicity of viral hemorrhagic septicemia virus from free-living turbot (Psetta maxima) in a Turkish coastal area of the Black Sea.

Viral hemorrhagic septicemia (VHS) is one of the most serious fish viral diseases for cultured rainbow trout (Oncorhynchus mykiss), although VHS virus (VHSV) seems to be ubiquitous among marine fishes. In the present study, VHSV isolation was performed with free-living and cultured turbot (Psetta maxima) in the Trabzon coastal area of the Black Sea to evaluate participation of VHSV in mass mortalities of seed-produced turbot larvae. VHSV was detected in 14 of 66 free-living spawners (positive ratio, 21.
