A babesiose bovina, causada pelos protozoários intraerotrocíticos Babesia bovis e B. bigemina tem como principal vetor Rhipicephalus (Boophilus) microplus, sendo este o único vetor biológico dos parasitas da família Babesiidae no Brasil. Clinicamente as babesioses caracterizam-se por febre, anemia, hemoglobinemia, hemoglobinúria e fraqueza, podendo evoluir para a morte em casos graves da doença, estando a gravidade da enfermidade diretamente relacionada à reação do hospedeiro frente à infecção. B. bovis e B. bigemina, espécies que ocorrem simultaneamente em várias regiões do mundo acompanhando a presença do vetor. As perdas ocasionadas pela babesiose bovina são atribuídas ao menor ganho de peso dos animais, decréscimo na produção de leite, infertilidade de...

Tristeza parasitária dos bovinos: quando vacinar é preciso.
Provedor de dados: 14
Autores: KESSLER, R. H.; SOARES, C. O.; MADRUGA, C. R.; ARAÚJO, F. R. de.
A tristeza parasitária dos bovinos (TPB), causada por Babesia bovis, Babesia bigemina e Anaplasma marginale, é conhecida desde o final do século XIX. A premunição (infecção/tratamento), como método de profilaxia, tem sido usada desde o início do século XX. A partir dos anos 60 e 70, pesquisadores australianos publicaram vários trabalhos sobre o desenvolvimento de vacinas atenuadas de B. bovis e B. bigemina, que associadas ao isolado de Anaplasma centrale, organismo naturalmente pouco patogênico, promoviam imunidade contra a babesiose e a anaplasmose. Esta metodologia foi difundida para outros países, entre eles o Brasil, onde se encontra à disposição de veterinários e pecuaristas. Dois tipos de vacinas atenuadas contra a TPB estão sendo utilizados no...

Prevalence and chemotherapy of babesiosis among Lohi sheep in the Livestock Experiment Station, Qadirabad, Pakistan, and environs
Provedor de dados: 80
Autores: Rashid,A; Khan,JA; Khan,MS; Rasheed,K; Maqbool,A; Iqbal,J.
A total of 310 blood smears were collected from sheep of the Livestock Experiment Station, Qadirabad, Sahiwal district, Pakistan, and surrounding areas. The samples were examined microscopically and 30 (9.67%) were positive for babesiosis. The animals were divided into two groups (A and B) for chemotherapy. Group A sheep were treated with diminazene diaceturate while group B animals received imidocarb dipropionate. Drug efficacy was determined by negative blood smear examination. Diminazene diaceturate effectiveness against babesiosis was 80% while that of imidocarb dipropionate was 100%. Hematological studies revealed a significant decrease in hemoglobin concentrations and hematocrit values for Babesia-positive animals compared to healthy controls.

Protective immunity of blood plasma fraction containing Babesia rodhaini exoantigens in mice
Provedor de dados: 19
Autores: Kamiya, Shiho; Takabatake, Noriyuki; Fujii, Kei; Okamura, Masashi; Iseki, Hiroshi; Yokoyama, Naoaki; Igarashi, Ikuo.
Babesia spp. are major hemoprotozoan parasites in animals. Exoantigens, which are soluble antigens released by the parasites during their asexual development, have been successfully applied for the development of a vaccine against babesiosis. In this study, we examined the ability of exoantigens to induce protective immunity in mice against a rodent Babesia parasite, Babesia rodhaini. The BALB/c mice immunized with the blood plasma fraction of B. rodhaini-infected mice (B. rodhaini exoantigens) showed a significant decrease in the lethal rate when challenged with B. rodhaini. Western blot analysis with anti-B. rodhaini exoantigen immune serum specifically detected at least eleven proteins in the lysate of B. rodhaini-infected erythrocytes. Next, a cDNA...

Provedor de dados: 19

Oligomannose-coated liposome (OML)-based vaccines have been reported to induce Th1-based immunity against entrapped antigens in immunized animals and to show protective effects against several protozoal diseases. In the present study, we produced a recombinant Babesia rodhaini ribosomal phosphoprotein P0 (rBrP0) that showed immunological cross reactivity with another rodent Babesia parasite, B. microti. We evaluated the efficacy of vaccination with OML-entrapped rBrP0 on B. rodhaini and B. microti infections in mice. Prior immunization with the OML-based rBrP0 vaccine, or with a Freund’s adjuvant-based rBrP0 vaccine, failed to demonstrate any protective effect against lethal infection with B. rodhaini, but the OML-based vaccine did induce protective...

Informe de tres casos de rabia paralítica y babesiosis bovina en el municipio de Aldama, Tamaulipas
Provedor de dados: 108
Autores: Ramírez Romero,Rafael; González Báez,Andrea; Nevárez Garza,Alicia Magdalena; Rodríguez Tovar,Luis Edgar.
Se presentan los antecedentes, las manifestaciones clínicas, los hallazgos patológicos e histopatológicos, así como los resultados de los estudios complementarios de tres animales representativos de un problema de mortalidad en ganado de carne en un rancho localizado en el municipio de Aldama, Tamaulipas, durante el primer trimestre de 2008. El diagnóstico presuntivo en dos casos fue babesiosis y en el otro fue rabia. La zona es considerada endémica para ambas enfermedades. Los resultados demostraron que el problema primordial fue rabia (3/3); sin embargo, en dos de ellos (2/3) también se registró la presencia de Babesia bovis. En zonas endémicas, la presencia de ambas enfermedades, rabia paralítica bovina y babesiosis ocurre simultáneamente haciendo...

Occurrence of congenital in Theileria equi Lusitano pure blood foals, diagnosed by RT-PCR
Provedor de dados: 195
Autores: Roncati, Neimar V.; Baccarin, Raquel Yvonne Arantes; Massoco, Cristina de Oliveira; Fernandes, Wilson Roberto.
In order to determine the occurrence of transplacentary transmission of Theileria equi in equine neonates, 50 foals of the Lusitano breed, both colts and fillies, along with their respective mothers were evaluated shortly after parturition. Total blood samples were collected from the mothers and the neonates within the first five hours after parturition for the detection of Theileria equi, through use of the RT-PCR technique. The detection kit based on the intercalating dye of DNA SYBERgreen was used. A total of 46% of the mares presented a positive result for Theileria equi and 54% presented negative ones, while 66% of the foals presented positive results, seeing as 73.9% of them were born from also positive mothers. The remaining 34% of foals presented...

ABSTRACT: Canine babesiosis is a common haemoparasitosis in Brazil. Caused by parasites of the genus Babesia, it is transmitted by ixodid ticks and affects domestic and wild canids. The objective of this study was to verify the prevalence of Babesia species (spp.) using molecular methods in dogs living in urban and rural areas of Cuiabá, Mato Grosso State, Brazil, and to identify the main factors associated with infection. A total of 407 samples from 407 dogs were evaluated using a polymerase chain reaction (PCR) technique, among which Babesia species (spp.) was amplified in 10 (2.5%). Although, no statistical association was found among the variables studied (p&gt;0.05), greater positivity was observed in dogs&lt;1 year of age, male sex, those with free...
