| A total of 250 blood samples were collected from clinically healthy cattle in five provinces of Philippines. DNA was extracted from the samples and analyzed by nested PCR assays for an epidemiological survey of Babesia bovis and Babesia bigemina infections. Out of the 250 samples, 27 (10.8%) and 16 (6.4%) were positive for B. bovis infection and B. bigemina infection, respectively. Mixed infections were detected in a total of 4 samples (1.6%). Our data provide baseline information regarding the epidemiology of B. bovis and B. bigemina infections in cattle in Philippines, which can be utilized in developing proper strategies for disease control and management. |

| A fragment of a novel gene, designated as the BboP67 gene, of Babesia bovis, which had been recently reported as a homolog of the gene encoding a sporozoite-specific P67 antigen of Theileria parva, was isolated from the genomic DNA of B. bovis and expressed as a recombinant (rBboP67) in E. coli. The antigenicity of rBboP67 was evaluated using 102 and 68 field serum samples collected from cattle in Ghana and Mongolia, respectively. All of the B. bovis- and B. bigemina-infected sera, which had been identified by the species-specific antigens, rRAP-1/CTs, for B. bovis and B. bigemina in the standard ELISA, positively reacted with the rBboP67 in ELISA. While B. bovis-infected field serum samples recognized the rBboP67 in Western blot analysis, sera collected... |

| The in vitro inhibitory effect of fosmidomycin was evaluated against the asexual growth of bovine Babesia parasites (Babesia bovis and Babesia bigemina). In the cultures with these parasites, severe reduction of parasite growth was observed by the addition of 1.25 μg/ml of the final drug concentration. Under these conditions, B. bigemina was completely cleared until the third day of cultivation. On the other hand, B. bovis was completely eliminated on the fourth day when the concentration was 6.25 μg/ml in the culture. These parasites failed to grow again when a drug-free medium was substituted for the subsequent cultivation. The IC50 values of fosmidomycin against B. bovis were determined as 0.88 and 0.63 μg/ml in the in vitro cultures with... |

| High rise of temperature (41.3℃), hemoglobinurea, anorexia, decrease milk production, anemia and diarrhea were observed in a cross-bred cow of aged 4 years, maintained in the dairy farm of ICAR research complex for North Eastern Hill Region, Umiam, Meghalaya, India, in its 3 months of lactation. After examination of Giemsa stained blood smears and molecular diagnosis using polymerase chain reaction, the disease was diagnosed as babesiosis caused by Babesia bigemina. The animal was treated successfully with a single injection of 4,4' diamidine diazoamine benzene diaceturate in recommended dose. No parasite was detected by examination of Giemsa stained blood smears after a period of 48 hours post treatment onwards. A total loss of 51.6 liter milk production... |

| A ação da diidroxitetraciclina de longa duração foi testada em bezerros experimentalmente inoculados com Babesia bigemina e em desafio natural em área endêmica. Em uma propriedade de gado de leite, 18 bezerros foram inoculados com 10(8) hemácias parasitadas por B. bigemina. Dez animais foram tratados com 20 mg/kg de diidroxitetraciclina de longa ação, sete dias após o inóculo, e oito foram deixados como controle. Todos os animais do grupo controle e apenas três dos tratados apresentaram parasitemia, sendo que dois já estavam infestados no dia do tratamento. Em um segundo experimento, dez bezerros receberam dois tratamentos de 20 mg/kg de diidroxitetraciclina de longa ação aos 15 e 36 dias após serem liberados em piquetes e oito bezerros foram deixados como... |

| Babesia bovis, B. bigemina, Trypanosoma evansi, and Anaplasma marginate infections cause serious diseases in cattle, and are primarily transmitted by arthropod vectors (ticks for B. bovis, B. bigemina, and A. marginate and various types of flies for T. evansi). In the last few years, there have been many reports of a high prevalence of certain protozoan infections in northern Egypt, but no accurate or adequate data are available for the southern regions. Therefore, in this study, we screened for evidence of such diseases in economically important cattle species using serum samples. The seroprevalence of protozoan infections in cattle was determined with enzyme-linked immunosorbent assays using species-specific diagnostic antigens. In a total of 301 cattle... |

| A babesiose bovina é uma hemoparasitose causada, no Brasil, pelos protozoários B. bovis e B. bigemina, as quais apresentam como único vetor biológico o carrapato Boophilus microplus. Foram avaliadas amostras dos animais da Estação Experimental de Estudos de Bovinos Curraleiros (EEEC) colhidas nos anos de 2001 (n=117) e 2003 (n=113). A detecção de anticorpos anti-B. bovis e anti-B. bigemina foi realizada pelo ELISA-indireto. O objetivo deste trabalho foi estudar a soroepidemiologia da babesiose bovina em rebanho Curraleiro, obter informações sobre a situação da doença na população e relacionar os resultados obtidos com informações edafoclimáticas e de manejo disponíveis. A taxa de ocorrência em 2001 foi de 92,3% para B. bovis e de 83,8% para B. bigemina e,... |
