“…Herd seroprevalences are highly variable. In Austria, the average flock prevalence was reported to be 31.3% [24] but may be as high as 83% [27]. In several studies, the seroprevalence in goats was found to be significantly higher in herds that had contact to cattle [22,24,27].…”

In several studies, the seroprevalence in goats was found to be significantly higher in herds that had contact to cattle [22,24,27]. Interestingly, compared to sheep where BDV antibodies are most prevalent, pestivirus antibodies in goats are more often not clearly specifiable or are rather directed against BVDV [25,27].…”

Bovine viral diarrhoea virus (BVDV) is an economically important pathogen of cattle worldwide. Infection of a pregnant animal may lead to persistent infection of the foetus and birth of a persistently infected (PI) calf that sheds the virus throughout its life. However, BVD viruses are not strictly species specific. BVDV has been isolated from many domesticated and wild ruminants. This is of practical importance as virus reservoirs in non-bovine hosts may hamper BVDV control in cattle. A goat given as a social companion to a BVDV PI calf gave birth to a PI goat kid. In order to test if goat to goat infections were possible, seronegative pregnant goats were exposed to the PI goat. In parallel, seronegative pregnant goats were kept together with the PI calf. Only the goat to goat transmission resulted in the birth of a next generation of BVDV PI kids whereas all goats kept together with the PI calf aborted. To our knowledge, this is the first report which shows that a PI goat cannot only transmit BVD virus to other goats but that such transmission may indeed lead to the birth of a second generation of PI goats. Genetic analyses indicated that establishment in the new host species may be associated with step-wise adaptations in the viral genome. Thus, goats have the potential to be a reservoir for BVDV. However, the PI goats showed growth retardation and anaemia and their survival under natural conditions remains questionable.

Transmission of Bovine Viral Diarrhea Virus to Adult Goats from Persistently Infected Cattle

et al. 2007

Abstract. The transmission of bovine viral diarrhea virus (BVDV) from persistently infected (PI) heifers to adult seronegative goats was examined in this study. Ten seronegative adult goats were exposed to 4 PI heifers. None of the goats developed any clinical signs but all goats seroconverted by 42 days after exposure to the PI cattle. Results indicate that goats are susceptible to BVDV infection when housed with PI cattle.Key words: Abortion; border disease; bovine viral diarrhea; goats.Bovine viral diarrhea virus (BVDV) is a significant cause of morbidity and mortality among cattle in the United States, causing respiratory and reproductive disease, both of which lead to decreased productivity. The most damaging effect of BVDV infection is the establishment of a persistently infected (PI) animal; these cattle may appear to be asymptomatic while shedding the virus and infecting other animals. 5,10 The goat population in North America has increased dramatically in the past few years, in part as a result of increased demand for goat meat from ethnic populations. 25 In addition, livestock producers are encouraged to commingle goats with cows to efficiently use forage that cattle eat less preferentially and to control internal parasites by reducing the parasite load in the environment. 20 Pasturing goats with cattle, however, may increase the risk of BVDV infection in goats. The potential for BVDV transmission from cattle to goats and the generation of PI goats would have practical implications, such as BVDV abortions in goats and propagating PI goats that can serve as sources of BVDV infection for cattle and goats.Pestiviruses and their natural hosts include BVDV of cattle, border disease virus (BDV) of sheep, and classical swine fever virus (CSFV) of pigs. These viruses are typically isolated from primary host species, but are capable of infecting other species. 17 The 4 recognized pestivirus species, BVDV 1, BVDV 2, BDV, and CSFV are genomically and antigenically very similar to each other. and wild deer. 6,26 Of these species, BVDV infection of sheep and goats could be of the most importance in transmission to cattle because of the frequent pasturing of these species in common. Several outbreaks of BVDV infection in sheep have been reported, 2 where the most common manifestation of disease is reproductive losses. Inoculation of pregnant ewes at different points of gestation results in abortions and PI lambs.23 Bovine viral diarrhea virus infections in nonpregnant goats are also subclinical. Disease in goats due to BVDV infection differs in sheep in that abortions are more commonly reported than PI offspring. 4,18 Goats have been reported to be infected with BVDV by natural transmission. 7,14,15,27 Seropositivity among goat populations varies around the world: 1.8% 7 to 16% in North America (1982-1983) 15 ; 31.4% in Africa (1998) 27 ; and 11.5% in Europe, 2006. 14 Review of the current literature indicates that goats can be experimentally infected with BVDV by direct inoculation. 4,16,19 In a previous s...

“…Em seis propriedades positivas houve apenas um animal soropositivo, e apenas um rebanho apresentou três animais soropositivos entre oito testados, com títulos de 40, 80 e 160 (dados não apresentados), o que sugere a infecção prévia destes animais por um pestivírus e possivelmente de animais com infecção aguda. Levando-se em consideração que nessa propriedade há criação consorciada de caprinos e bovinos, a transmissão pode ter ocorrido entre as espécies (LOKEN, 1995;KRAMETTER-FROETSCHER et al, 2010), e acredita-se que provavelmente os bovinos estejam atuando como fontes de infecção.…”

“…Em caprinos, a ocorrência de casos clínicos da infecção por Pestivirus é baixa, no entanto, a doença pode apresentar-se de forma branda a severa (KRAMETTER-FROETSCHER et al, 2006). Por outro lado, a ocorrência de animais PI garante a persistência do vírus nos rebanhos.…”

ResumoO objetivo do presente trabalho foi determinar a prevalênciade anticorpos anti-pestivírus em caprinos leiteiros do semiárido do Estado da Paraíba, Nordeste do Brasil, bem como identificar fatores de risco associados à prevalência de rebanhos positivos. Foram utilizados 1.092 cabras leiteiras de 110 propriedades selecionadas aleatoriamente no Município de Monteiro, Estado da Paraíba, no período de março de 2009 a março de 2010. Em cada propriedade selecionada foi aplicado questionário epidemiológico para verificar a ocorrência de possíveis fatores associados à ocorrência da infecção. Para o diagnóstico sorológico da infecção por Pestivírus, foi utilizada a prova de soroneutralização com a estipe de BVDV-1 NADL. A prevalência de propriedades positivas foi de 6,36% (IC 95% = 2,60% -12,67%) e a prevalência de animais soropositivos foi de 0,82% (IC 95% = 0,38% -1,56%). Não realizar vermifugação (odds ratio= 10,49; p = 0,035) e realizar corte e desinfecção de umbigo (odds ratio= 12,73; p = 0,034) foram identificados como fatores de risco. Os resultados obtidos indicam a circulação viral em caprinos leiteiros do semiárido da Paraíba. Palavras-chave: Caprinocultura leiteira, sanidade animal, Pestivirus, epidemiologia AbstractThe aim of this survey was to determine the prevalence of anti-pestivirus antibodies in dairy goats from the semiarid region of the Paraíba state, Northeastern Brazil, as well as to identify risk factors associated with the flock-level prevalence. A total of 1,092 dairy goats from 110 flocks randomly selected in the county of Monteiro, Paraíba state, during March 2009 to March 2010, were used. In each selected flock a epidemiological questionnaire was applied to verify the occurrence of possible factors that could be associated with the flock-level prevalence. For the serological diagnosis of Pestivirus infection the serum neutralization test, using the BVDV-1 NADL strain, was carried out. Flock-level prevalence was 1 Parte integrante da Tese de Doutorado do primeiro autor.
