Molecular epidemiology and phylogenetic analysis of diverse bovine astroviruses associated with diarrhea in cattle and water buffalo calves in China
Astroviruses are the principal causative agents of gastroenteritis in humans and have been associated with diarrhea in other mammals as well as birds. However, astroviral infection of animals had been poorly studied. In the present study, 211 rectal swabs collected from cattle and water buffalo calves with mild to severe diarrhea were tested for bovine astrovirus (BAstV) by RT-PCR. Results: 92/...
متن کاملIsolation of small viruses resembling astroviruses and caliciviruses from acute enteritis of calves.
Small round viruses (SRV) were isolated from the faeces of diarrhoeic calves from three farms. All three SRV preparations caused diarrhoea experimentally in gnotobiotic calves. Each preparation contained viral particles of two morphological types, "astrovirus-like" and "calicivirus-like", and from one preparation the two particle types were separated from each other. The calicivirus-like agent ...
متن کاملDetection and Identification of Enzootic Bovine Leukosis (EBL) in Calves in Iran
Enzootic bovine leukosis (EBL) is known as bovine lymphosarcoma and normally affects the old cattle. EBL is caused by bovine leukemia virus (BLV), which is generally spread all around the world. This virus is transmitted via bovine blood products within and between cattle herds. Glycoprotein GP51 in the blood is responsible for cattle immune responses to BLV. This virus has been previously dete...
متن کاملVibrionic Enteritis in Calves
An intestinal disorder of calves has been described. The clinical manifestations are usually observed in calves 2 or more weeks old. Our experiments indicate that infection may take place relatively early in life and may for a time produce only a mild reaction, but as the disease becomes more chronic the clinical manifestations become more pronounced. The anterior portion of the jejunum is the ...
متن کاملIdentification of a Bovine Enteric Calicivirus, Kırklareli Virus, Distantly Related to Neboviruses, in Calves with Enteritis in Turkey.
A calicivirus was detected in neonatal calves with enteritis in Kırklareli, Thrace, Turkey. In the full-length genome, Kırklareli virus was related (48% nucleotide identity) to bovine enteric caliciviruses (Nebovirus genus). The virus was also detected in a herd in Ankara, Central Anatolia, but not in other Turkish prefectures.
