“…Infected goats are considered the main reservoir and source of infection of CAEV (LARA et al, 2005). Transmission occurs more frequently by the ingestion of contaminated colostrum and milk by goat kids in their initial months of life.…”

Caprine arthritis encephalitis virus (CAEV) is a retrovirus that infects goats. This study evaluated the prevalence of CAEV in breeder goats from the states of Maranhão, Ceará, Piauí, Alagoas, Sergipe, Rio Grande do Norte, and Paraíba. We collected a total of 531 serum samples from 251 properties. On average, two male breeder goats were examined from each farm. Results from western blotting demonstrated that the prevalence of CAEV was 6.2% (32/513). In each state, the following prevalence values were found: Piauí, 5.9% (7/119); Maranhão, 2.0% (01/48); Sergipe, 7.1% (03/42); Alagoas, 17.6% (03/17); Rio Grande do Norte, 4.7% (05/105); Paraíba, 2.1% (02/94); and Ceará, 12.5% (11/34). We also conducted a univariate analysis to determine the risk factors that are associated with CAEV. This analysis revealed that breeding season, records of herd data, criteria adopted for the first mating of females, castration of male goats, origin of breeders, and identification of the animal were associated with CAEV. Adopting control measures to identify CAEV-positive animals and avoid virus transmission to females, especially during breeding seasons, is crucial since, males carrying CAEV can be sources of infection for the entire herd.

“…In addition to the mentioned bacteria other microorganisms can cause intramammary infections in goats. Caprine Arthritis-Encephalitis Virus (CAEV) is classified as RNAvirus of the Retroviridae family and Lentivirus genus [56] and has a tropism for the udder. The CAEV infections are characterized by interstitial and clinical indurative mastitis ("hard udder") in dairy goats.…”

Background: Intramammary infections constitute a major animal health and economic problem in commercial dairy goat farms, being responsible for decreases in milk yield, for alter milk composition, and lower milk quality. Objectives: This paper reviews the published literature during last three decades, highlighting the multiplicity of non-infectious and infectious factors that influence somatic cells count (SCC). Besides that, it intends to contributes to understand the conventional diagnostic methods and its limitations, and supports the implementation of new technologies for an efficient mastitis control, including the use of infrared thermography and ultrasonography. Methods: A search on Medline, ScienceDirect and University Institutional Repositories databases was performed using “goats AND mastitis OR intramammary infections OR somatic cells count” for publications from 1990 to present (2020). Results: A total of 144 publications were selected. The SCC is the most important criteria to evaluate the inflammatory status of the mammary glands in goats, but several non-infectious factors (e.g., phenotypic, reproductive, lactational factors) should be taken in consideration for it interpretation. Bacteria and fungi as well lentivirus are commonly responsive for intramammary infections. Intermittent secretion or environmental contamination of milk pathogens, costs and time delay pose challenges using conventional diagnosis methods. Ultrasonographic and thermographic techniques applied to the udder seems to be diagnostic value in acute and chronic mastitis. Conclusions: Unlike other ruminants species, non-infectious factors have a major impact on SCC which should be taken in account for mastitis diagnosis, and according to milk pathogens detection. Further research in imagological techniques is need to accurately contributes to implant new mastitis control strategies.
