Snakebites are a serious public health problem due their high morbi-mortality. The main available specific treatment is the antivenom serum therapy, which has some disadvantages, such as poor neutralization of local effects, risk immunological reactions, cost and difficult access in regions. In this context, search for alternative therapies relevant. Therefore, aim study was to evaluate antiophidic properties Jatropha gossypiifolia, medicinal plant used folk medicine treat snakebites....
This article studied the integration of active methodologies in teaching activities. As such, problem aimed to determine what extent can be adapted different educational contexts and levels teaching. Aware this, main objective was analyze effective use activities, focusing on problem-based learning, project-based flipped classroom. a methodology, qualitative literature review explored. In results, it observed that application has shown significant improvements understanding retention...
The resistance of gastrointestinal nematodes (GINs) small ruminants to anthelmintics has required the investigation new alternatives. aim present study was evaluate in vivo anthelmintic activity an aqueous extract from sisal waste (Agave sisalana) (AESW) against GINs goats and observe animals for toxic effects. Thirty that were naturally infected with distributed into three groups: group I, treated daily doses AESW (1.7 g/kg) eight days; Group II, positive control, a single dose levamisole...
This study was conducted in order to evaluate the transmission of caprine lentivirus sheep using different experimental groups. The first one (colostrum group) formed by nine lambs receiving colostrum from goats positive for small ruminant lentiviruses (SRLV). second group (milk established that received milk these goats. Third a control group, consisting suckled and negative mothers. Another (contact eight adult sheep, confined with two naturally infected groups were monitored...
A artrite-encefalite caprina (CAE) é diagnosticada rotineiramente pela técnica de imunodifusão em gel agarose (IDGA), que considerada pouco sensível. Objetivou-se com este estudo padronizar testes Elisa-i e Western Blot (WB) para diagnóstico precoce anticorpos caprinos contra CAEV comparar os resultados obtidos nesses a prova IDGA. Para padronização dos WB, utilizaram-se diferentes concentrações diluições antígeno, soros conjugado. No Elisa-i, adotaram-se microplacas rígidas 96 poços, sendo...
ABSTRACT: Caprine arthritis encephalitis causes considerable losses in goat production. The main form of the caprine virus transmission is through ingestion colostrum or milk from infected females. However, some transmissions cannot be explained this manner. Therefore, study aimed to evaluate transplacental virus. Blood samples were collected 283 newborn kids Anglo-Nubian and Saanen breeds born seropositive seronegative goats. Samples immediately after birth analyzed with agarose gel...
The introduction of new breeds, aiming at increasing productivity, caused the change in health profile herds. Among diseases introduced Brazil lentiviroses small ruminants (LVPR) stand out, represented by caprine arthritis encephalitis (CAE) and maedi-visna (MV). In order to obtain data concerning presence maedi visna (MV) sheep herds microregion Juazeiro, Bahia, 919 serum samples were evaluated agar gel immunodiffusion (AGID). collected eight cities that make up this (Juazeiro, Sento Sé,...
Este trabalho teve como finalidade verificar a prevalência sorológica da lentivirose caprina (LVC) na microrregião de Juazeiro, Bahia, por meio técnica imunodifusão em gel agar (IDGA), bem caracterizar os sistemas criação região. Para tal, foram avaliadas 693 amostras soros sanguíneos caprinos 46 propriedades rurais diferentes localidades, pertencentes aos 8 municípios formadores (Campo Alegre Lourdes, Casa Nova, Curaçá, Pilão Arcado, Remanso, Sento Sé e Sobradinho). Na realização das...
Com o objetivo de analisar a ocorrência anticorpos contra Brucella ovis em ovinos no semiárido baiano, este inquérito foi conduzido rebanhos da microrregião Juazeiro, Bahia. O teste imunodifusão gel ágar (IDGA) utilizado para examinar 694 amostras soro 58 rebanhos. Anticorpos B. foram observados cinco (0,72%) dos animais investigados. Acredita-se que baixo número soropositivos deva-se às características sistemas produção, com predominância do tipo exploração extensiva localmente adaptados,...
ABSTRACT With the objective of detecting presence caprine lentivirus (CLV) in ewe milk and ram semen, ten matrixes four reproducers experimentally infected with CLV were used. Samples collected during months lactation, five collections per animal, totaling 50 samples. Regarding rams, eight semen made one year experimentation, 32 The samples submitted to DNA extraction nested polymerase chain reaction test (nPCR) detect proviral DNA. Eight (16%) positive nPCR originating from two ewes. Only...
A artrite-encefalite caprina (CAE) e a Maedi-Visna (MV) sao doencas de curso progressivo, que acometem caprinos ovinos, respectivamente. Durante anos, o agente etiologico viral dessas enfermidades era considerado como especifico cada especie. Entretanto, analises filogeneticas tem demonstrado heterogeneidade desse virus, reunindo diferentes genotipos subtipos em um grupo denominado lentivirus pequenos ruminantes (LVPR). Alem disso, diversos estudos revelaram ocorrencia da infeccao ovinos por...
O objetivo do presente trabalho foi a realização de um inquérito soroepidemiológico Brucella ovis em rebanhos ovinos da Microrregião Feira Santana, Estado Bahia, Brasil. Foram selecionados os dez municípios maior efetivo ovino: Antônio Cardoso, Ipecaetá, Ipirá, Itatim, Pintadas, Rafael Jambeiro, Santa Teresinha, Santo Estévão e Serra Preta,. tamanho amostra calculado com base nos parâmetros: nível significância, 99%; erro amostral, 5%, prevalência estimada, 50%. A total fracionada segundo...
O objetivo deste trabalho foi avaliar a ocorrência de ovinos soropositivos para o vírus da língua azul (VLA) no Estado do Ceará, Brasil, e analisar as proteínas imunogênicas das cepas virais circulantes nesses rebanhos. teste imunodifusão em gel agarose (IDGA) utilizado pesquisar 271 amostras soro oriundas 16 Os resultados demonstraram que 27,3% (74/271) analisadas apresentaram anticorpos contra agente 68,8% (11/16) propriedades tiveram animais positivos. immunoblotting (IB) VLA partir dos...
O objetivo deste trabalho foi descrever um surto de intoxicação por ionóforo em rebanho ovinos, onde vinte animais morreram após o uso monensina sódica na dieta. Os sinais clínicos apresentados pelos incluíram hipertermia, anorexia, diarréia, taquicardia, resistência a exercícios e marcha irregular. Na necropsia animal, foram constatadas áreas pálidas musculatura esquelética no miocárdio, hemorragias epicárdio edema pulmonar. exame histopatológico revelou degeneração necrose hialina...
It was analyzed the occurrence of failure passive transfer (FTIP) immunity 45 born lambs healthy and pluriparous ewes. These animals were accompanied from birth to wean (90 days), when clinical evaluations accomplished, hemogram, determination total serum proteins their electrophoretic fractions, 24-72h after birth, 7, 15, 30, 60 90 days age (at same time wean). Adopting cut point for order 4.5g/dL, it obtained FTIP 24.4% (11 animals). The with presented lowers values (p<0.05) proteins,...
In order to evaluate the passive immunity against small ruminant lentiviruses (SRLV) in lambs, this study was conducted from two experimental groups. The first one (G1) established by nine lambs subjected artificial feeding of colostrum goats positive for SRLV. second (G2) control group, consisting ten suckling their negative mothers. Blood samples were obtained before feeding, after 24 hours birth and at 7, 15, 30, 50, 70, 90 120 days age. concentrations total serum protein (TSP), albumin...
ABSTRACT: This study was conducted to evaluate caprine arthritis encephalitis virus (CAEV) transmission among sheep using 15 lambs that were distributed in 2 experimental groups. The exposed group consisted of 10 remained with their mothers, who experimentally infected CAEV. non-exposed characterized as the control and comprised 5 CAEV-negative mothers. Blood samples collected monthly from birth until 1 year life. To transmission, an agar gel immunodiffusion test (AGID), enzyme immunoassay...
