“…It has been reported in many studies that the percentage of seropositive animals in groups of cows and bulls was comparable and did not differ statistically; also animal sex had no influence on BVDV spread (Polak and Zmudzinski 1999;Mockeliuniene et al 2004). Therefore, only female cows were tested for antibodies against BVDV in this study.…”

A cross-sectional study was carried out to determine the seroprevalence and to identify risk factors associated with bovine viral diarrhea virus (BVDV) infection in 62 non-vaccinated dairy herds (671 cows) in Jordan between January and June 2007. Information regarding herd management was recorded through a personal interview with farmers. Antibodies against BVDV were detected using an indirect ELISA test. Chi-square analysis and multivariable logistic regression model were used to identify risk factors for BVDV seropositivity. The true prevalence of antibodies against BVDV in individual cows and cattle herds was 31.6% and 80.7%, respectively. The seroprevalence of BVDV in medium and large size herds was significantly higher than that in smaller herds. There was no significant difference in BVD seroprevalence between different age groups. Random-effects logistic regression model revealed two major factors associated with seropositivity to BVDV; exchange of visits between adjacent farm workers and not isolating newly purchased animals before addition to the herd. The seroprevalence of BVDV in cows located in the northern Jordanian governorates was significantly higher than that in other studied governorates. Results of this study indicated that BVDV is highly prevalent in Jordan and BVDV infection could be controlled by livestock-trade control, and applying strict biosecurity measures in the dairy farms.

“…4 Persistently infected calves basically are immunotolerant to the virus strain and perfect carriers that keep shedding the virus for their entire lives. 5 Infection to BVDV during the pregnancy period may also lead to early embryonic death where the animal will return to estrus cycle, calf born with congenital diseases, or born weakened. If naive non-pregnant cattle with no vaccination for BVDV come in contact with the agent, it may result in transient viremia that leads to short-term leucopenia, immunosuppression, agalactia, lymphopenia, pyrexia, and diarrhea.…”

Research ABSTRACTThe aim of this study was to investigate Seroprevalence of Bovine Viral Diarrhea Virus (BVDV) infection in cattle in the state of Selangor, Malaysia and associated risk factors. A total of 407 blood samples were collected from five selected farms within Selangor. Sampled animals were identified for their breed, age, lactation and pregnancy status. The plasma extracted from blood samples were used for detection of antibody against BVDV using an ELISA test kit (Prio-CHECK ® BVDV antibody) following the manufacturer's protocol. Results demonstrated an overall 33.2% (135/407) prevalence of BVDV antibody; with four of the farms tested positive. Prevalence in one farm reached 75.9% (66/87) which was higher than the other four farms with a prevalence of 26.0% (66/254), 13.3% (2/15), 2.8% (1/36) and 0% (0/15). Animals grouped according to breed, age, lactation and pregnancy status showed significant variation in BVDV prevalence. Higher number of adults (36.7%) than young calves (15.2%), pregnant (42.9%) than non-pregnant (31.1%) and more lactating (51.1%) than non-lactating (25.8%) cows, were affected (p<0.05). Friesian-Sahiwal and Jersey cattle were the most affected while the local Kedah-Kelantan cattle were the least affected. In conclusion, the study revealed immense exposure of cattle in Selangor to BVDV infection that varied with breed, age, lactation, and pregnancy status of the animals. As to our knowledge, this is the first report on BVDV status in cattle in Malaysia and the seroprevalence result would serve as a baseline data for further investigation on the disease.

“…In Poland, prevalence of PI animals is similar to other geographic regions of Europe. In the late 1990s', 0.9% of bulls in artificial insemination centres in Poland were persistently infected with BVDV (23), while at the moment all the bulls at the stations are free from the virus after introducing the compulsory testing.…”

“…Their study, however, did not include measurement of the impact of colostral antibodies. In countries like Poland where the BVDV seroprevalence is high (23), and the cattle production is still rather extensive or semi-industrial, maternal immunity is an important consideration when establishing a testing method for BVDV control programmes. Our results confirm also the finding of Zimmer et al (28), who demonstrated that conventional RT-PCR identifies PI animals more accurately than antigen capture ELISAs in the presence of antibodies circulating in the blood of a PI calf.…”

Two issues concerning virus detection and identification of persistently infected (PI) cattle were analysed in the study: 1) interference by maternal antibodies and 2) discrimination between PI and transiently infected (TI) animals. Antigen ELISA and RT-PCR based methods were compared using serum samples from natural and experimental PI and TI calves. RT-PCR and realtime RT-PCR using primers within 5'UTR region were more sensitive in detecting PI animals than E rns and NS3 antigen capture
