Natural Intrauterine Infection with Schmallenberg Virus in Malformed Newborn Calves

ثبت نشده
چکیده

The Body as a Whole Schmallenberg virus (SBV)–positive calves were significantly lighter than SBV-negative calves (32 ± 15 vs. 49 ± 4 kg, p<0.05). The large deviation between SBV cases denotes a heterogeneous deficit of body weight. Notably, there was an obvious correlation between the body mass deficit and the severity of deformations in whole-body conformation (Table 1). Also, most deformed animals died spontaneously within 24 hours after birth (scores wholebody deformity score [WBD]–2 and −3). Among the least affected, the majority was euthanized. No significant morphologic changes were noted in the thoracic and abdominal cavities and organs.

Natural Intrauterine Infection with Schmallenberg Virus in Malformed Newborn Calves

We surveyed morphologic alterations in calves in Belgium that were naturally infected in utero by Schmallenberg virus (SBV) and born with deformities during January-March 2012. SBV-specific RNA was distributed unevenly in different tissues. Natural intrauterine SBV infection of calves might cause serious damage to the central nervous system and muscles.

Natural Infection of Pregnant Cows with Schmallenberg Virus – A Follow-Up Study

Schmallenberg virus (SBV), an orthobunyavirus discovered in European livestock in late 2011 for the first time, causes premature or stillbirth and severe fetal malformation when cows and ewes are infected during pregnancy. Therefore, cattle of two holdings in the initially most affected area in Germany were closely monitored to describe the consequence for fetuses and newborn calves. Seventy-on...

Congenital Malformations of Calves Infected with Shamonda Virus, Southern Japan

In 2015 and 2016, we observed 15 malformed calves that were exposed to intrauterine infection with Shamonda virus, a Simbu serogroup orthobunyavirus, in Japan. Characteristic manifestations were arthrogryposis and gross lesions in the central nervous system. Our results indicate that this arbovirus should be considered a teratogenic virus in ruminants.

Arthrogryposis, hydranencephaly and cerebellar hypoplasia syndrome in neonatal calves resulting from intrauterine infection with Aino virus.

To determine the teratogenic potential of Aino virus (AINOV) in cattle, pregnant cows and fetal cattle were infected with a fresh isolate of AINOV. Five pregnant cows were inoculated intravenously with the virus at 122 to 162 days of gestation and allowed to give birth. All of the cows developed neutralizing antibodies to the virus, indicating that the cows had been infected with the virus; how...
