Abstract - Neosporosis and toxoplasmosis are parasitic diseases which can cause reproductive problems in goats and sheep. The current study aimed to determine the occurrence of anti-Neospora caninum and anti-Toxoplasma gondii IgG antibodies in goats and sheep from the districts of Amarante do Maranhão and Buritirana, Imperatriz microregion, western area of Maranhão State, northeastern Brazil, and to assess factors associated to infection by these etiologic agents. Blood samples from 110 animals (46 goats and 64 sheep) from five herds were collected, and indirect immunofluorescence assay was used for serological testing. Of 46 goat samples, 17.39% (n = 8) showed anti-N. caninum antibodies and 4.35% (n = 2) anti-T. gondii, while of 64 sheep samples 4.69% (n = 3) and 18.75% (n = 12) showed anti-N. caninum and anti-T. gondii antibodies, respectively. No significant difference regarding the presence of domestic cats and/or dogs on the property and veterinary care was seen for both etiologic agents studied. However, food supplementation and animal reproductive failure were significantly (p < 0.05) for N. caninum among sheep and goats, respectively. The current study showed that goats and sheep in western Maranhão are exposed to N. caninum and T. gondii. It is the first evidence of these agents in small ruminants in this region.

O objetivo deste estudo foi determinar a ocorrência de anticorpos IgG anti-Neospora caninum e anti-Toxoplasma gondii em caprinos e ovinos dos municípios de Amarante do Maranhão e Buritirana, microrregião de Imperatriz, Oeste maranhense, Nordeste do Brasil, bem como avaliar fatores associados à infecção por esses agentes etiológicos. Amostras de sangue de 110 animais (46 caprinos e 64 ovinos), provenientes de cinco propriedades, foram coletadas, e a reação de imunofluorescência indireta utilizada para o diagnóstico sorológico.

Não houve diferença significativa, considerando-se a presença de gato e/ou cão na propriedade e assistência veterinária para ambos os agentes estudados. Entretanto, suplementação alimentar e presença de animais com problemas reprodutivos diferiram significativamente (p < 0,05) em ovinos e caprinos, respectivamente. Os resultados do presente estudo demonstraram que caprinos e ovinos, da região Oeste do Maranhão são expostos aos coccídios N. caninum e T. gondii. Essa é a primeira evidência desses agentes em pequenos ruminantes nessa região.

In this study, we describe a novel putative Enamovirus member, Grapevine enamovirus-1 (GEV-1), discovered by high-throughput sequencing (HTS). A limited survey using HTS of 17 grapevines (Vitis spp.) from the south, southeast, and northeast regions of Brazil led to the detection of GEV-1 exclusively on southern plants, infecting four grapevine cultivars (Cabernet Sauvignon, Semillon, CG 90450, and Cabernet franc) with a remark-able identity of around 99% at the nucleotide level. This novel virus was only detected in multiple-virus infected plants exhibiting viral-like symptoms. GEV-1 was also detected on a cv. Malvasia Longa by RT-PCR. We performed graft-transmissibility assays on GEV-1. The organization, products, and cis-acting regulatory elements of GEV-1 genome are also discussed here. The near complete genome sequence of GEV-1 was obtained during the course of this study, lacking only part of the 3 0 untranslated terminal region. This is the first report of a virus in the family Luteoviridae infecting grapevines. Based on its genomic properties and phylogenetic analyses, GEV-1 should be classified as a new member of the genus Enamovirus .
