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... |

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... |

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... |

The bovine tick Rhipicephalus (Boophilus) microplus is found in several tropical and subtropical regions of the world. This parasite transmits pathogens that cause disease, such as babesiosis ( Babesia bovis and B . bigemina ) and anaplasmosis (Anaplasma marginale). Tick infestations cause enormous livestock losses, and controlling tick infestations and the transmission of tick-borne diseases remains a challenge for the livestock industry. Because the currently available commercial vaccines offer only partial protection against R. (B.) microplus, there is a need for more efficient vaccines. Several recombinant antigens have been evaluated using different immunization strategies, and they show great promise. This work describes the construction and... |

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>0.05), greater positivity was observed in dogs<1 year of age, male sex, those with free... |

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... |

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. |

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... |

The aim of the present study was to determine the prevalence of Babesia bovis and Babesia bigemina in dairy cattle from São Luis Island in the state of Maranhão, Brazil. A total of 281 blood samples were collected. In total, 275 (97.9%) animals were B. bovis-reactive and B. bigemina-reactive in the Enzyme-Linked Immunosorbent Assay (ELISA). The microscopy examination detected 22 (7.8%) animals that were positive for Babesia sp. and the Polymerase Chain Reaction (PCR) analysis showed that 91 animals (32.38%) and 23 animals (8.18%) were positive for B. bovis and B. bigemina, respectively, while 17 animals (6.04%) were co-infected. There is a high level of transmission of these protozoa in Maranhão, and the animals were naturally exposed. Therefore, it is... |

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... |

Babesia bovis, a tick-transmitted apicomplexan protozoon, infects cattle in tropical and subtropical regions around the world. In the apicomplexans Toxoplasma gondii and Plasmodium falciparum, rhomboid serine protease 4 (ROM4) fulfills an essential role in host cell invasion. We thus investigated B. bovis ROM4 coding genes; their genomic organization; their expression in in vitro cultured asexual (AS) and sexual stages (SS); and strain polymorphisms. B. bovis contains five rom4 paralogous genes in chromosome 2, which we have named rom4.1, 4.2, 4.3, 4.4 and 4.5. There are moderate degrees of sequence identity between them, except for rom4.3 and 4.4, which are almost identical. RT-qPCR analysis showed that rom4.1 and rom4.3/4.4, respectively, display 18-fold... |
