Introduction Arboviruses are an important public health problem in Brazil, especially flaviviruses, including the Saint Louis encephalitis virus (SLEV) and Rocio (ROCV), problematic. These viruses transmitted to humans or other vertebrates through arthropod bites may cause diseases with clinical manifestations that range from asymptomatic infection, viral hemorrhagic fever encephalitis. Methods A serological survey of horses various regions Brazil using enzyme-linked immunosorbent assay...
Bovine leptospirosis causes economic losses and raises public health concerns. It is possible that there are peculiarities in the epidemiology of regions with a semiarid climate, such as Caatinga biome Brazil, where climate hot dry, etiological agent require alternative routes transmission. This study aimed to close knowledge gaps diagnosis Leptospira spp. infection cows from biome, Brazil. Samples blood, urinary tract (urine, bladder kidney) reproductive (vaginal fluid, uterus, uterine...
Para determinar as doenças que ocorrem no sistema nervoso de bovinos semiárido nordestino, foi realizado um estudo retrospectivo em 411 necropsias realizadas Hospital Veterinário da Universidade Federal Campina Grande, Patos, Paraíba, entre janeiro 2000 a dezembro 2008. Dos casos analisados 139 (33,81%) apresentaram alterações clínicas do e fichas foram revisadas para os principais achados referentes à epidemiologia, aos sinais clínicos às macroscópicas microscópicas. Em 28 (20,14%) o...
The objective of this study was to determine the seroprevalence leptospirosis and predominant serogroups in serological tests ruminants performed at Transmissible Diseases Laboratory Federal University Campina Grande, Patos, Paraíba, northeastern Brazil, between 2010 2017. This research included records for from 5594 animals, including 1527 cattle, 1761 goats, 2170 sheep, 136 buffaloes four Brazilian states (Paraíba, Pernambuco, Maranhão, Rio Grande do Norte). Of serum samples, 662 were...
The Caatinga biome occurs only in Brazil; however, there is no survey on leptospirosis using direct and indirect diagnostic tests this region with goats maintained field conditions. We conducted a prospective paired sampling to evaluate the importance of carrier maintenance disease. Based calculation, 60 (30 confined 30 extensively reared) were randomly selected monitored for three months during rainy season monthly biological sample collections. animals underwent urine vaginal fluid...
Outbreaks of eastern equine encephalitis observed from May 2008 to August 2009 in the Brazilian states Pernambuco, Ceará, and Paraíba are reported. The disease occurred 93 farms affecting 229 equids with a case fatality rate 72.92%. Main clinical signs were circling, depression or hyperexcitability, ataxia, progressive paralysis manifestation period 3-15 days. histologic lesions diffuse lymphocytic encephalomyelitis neuronal death, satellitosis, neuronophagia, hemorrhages being more severe...
A cross-sectional study based on a planned sampling was carried out to determine flock-level risk factors associated Leptospira spp. infection in dairy goat flocks semiarid region of Northeastern Brazil. Serum samples from 975 adult goats 110 were examined for antibodies by MAT using 24 serovars. structured questionnaire focusing leptospirosis completed each flock. Of the 48 (43.6%; 95% CI: 34.2–53.4%) presented at least one seropositive animal, and most frequent serovar Autumnalis (10.9%)....
ABSTRACT: Leptospirosis is a zoonotic infection caused by bacteria of the genus Leptospira spp. global importance, and in recent years efforts to isolate leptospires have intensified due importance using these isolated strains elucidate phylogenetic behavior genus. In this survey, efficiency transport medium (LTM) for leptospire isolation was evaluated 139 urine samples collected from bovine, goat, sheep swine slaughtered Caatinga biome, Brazil. DNA found 41/139 (29.5%) cultures pigs,...
Since the emergence of West Nile virus (WNV) in North America 1999, there have been several reports WNV activity Central and South American countries. To detect Brazil, we performed a serological survey horses from different regions Brazil using recombinant peptides domain III WNV. Positive samples were validated with neutralisation test. Our results showed that 79 ELISA-positive horses, nine expressed WNV-specific neutralising antibodies. Eight infected state Mato Grosso do Sul one was...
Leptospirosis is an infectious disease that affects domestic animals, wild and humans. It represents a public health problem has important economic impact on livestock. This study aims to investigate the importance of genital transplacental infection in epidemiology leptospirosis cows maintained Caatinga biome conditions, Northeastern Brazil, as well reporting organs colonized by Leptospira spp. embryos fetuses. Blood, urinary tract (urine, bladder, kidney), reproductive (vaginal fluid,...
Madariaga virus (MADV), the new species designation for South American isolates of eastern equine encephalitis (EEEV), is genetically divergent and substantially different in ecology pathogenesis from North EEEV strains. We isolated characterized a MADV isolate obtained horse Brazil. Our results support previous phylogenetic studies showing there are three distinct lineages. The Paraíba State belongs to lineage III closely related Peruvian, Colombian Venezuelan isolates.
To determine the presence of rabies virus in parotid salivary glands, 12 road-killed rabies-positive hoary foxes (Pseudoalopex vetulus) were tested by using fluorescent antibody test (FAT) and mouse inoculation (MIT). All glands positive for both tests, although some cases several passages required. The findings this study support importance fox as reservoir sem-iarid region Paraíba State, Northeastern Brazil.
Foi realizado um levantamento soroepidemiológico da leptospirose em caprinos microrregião do Seridó Oriental, Estado Rio Grande Norte, com o objetivo de determinar a prevalência anticorpos anti-Leptospira spp. e identificar fatores risco associados à infecção. Foram colhidas amostras soro sanguíneo 366 cabras idade reprodutiva 12 rebanhos. Para diagnóstico sorológico infecção por Leptospira spp., foi utilizada Soroaglutinação Microscópica (SAM) uma coleção 24 sorovares leptospiras vivas como...
Este trabalho teve como objetivos determinar a prevalência de propriedades caprinos leiteiros positivas e animais soropositivos para leptospirose no semiárido paraibano. A amostragem foi delineada determinação da (focos) infecção por Leptospira spp. No total, foram colhidas amostras sangue 975 procedentes 110 leiteiras localizadas Munícipio Monteiro, microrregião do Cariri Ocidental, Estado Paraíba. Para o diagnóstico spp., utilizado teste soroaglutinação microscópica (SAM), utilizando...
