1. Assessing bovine babesiosis in Rhipicephalus (Boophilus) microplus ticks and 3 to 9-month-old cattle in the middle Magdalena region, Colombia
Babesia sp. is a protozoan hemoparasite that affects livestock worldwide. The Colombian Middle Magdalena is an enzootic region for babesiosis, but there is no previous research providing detail on its transmission cycle. This study aims to assess some Babesia sp. infection indicators in cattle and ticks from the area, by using direct microscopic and molecula

2. Apoptotic-like activity of staurosporine in axenic cultures of Trypanosoma evansi
Trypanosoma evansi is a blood protozoan parasite of the genus Trypanosoma which is responsible for surra (Trypanosomosis) in domestic and wild animals. This study addressed apoptotic-like features in Trypanosoma evansi in vitro. The mechanism of parasite death was investigated using staurosporine as an inducing agent. We evaluated its effects through several

4. Produção das proteínas recombinantes AM254, VirB9 e VirB10, de Anaplasma marginale e avaliação preliminar de sua antigenicidade. / Production of recombinant proteins AM254, VirB9 and VirB10 of Anaplasma marginale and preliminary evaluation its antigenicity.
Anaplasma marginale (Ricktsialles: Anaplasmataceae) is a ricketsial hemoparasite responsible for causing great economic losses in cattle from tropical and subtropical regions. The objectives of this work were to produce the recombinant membrane proteins AM254, VirB9 and VirB10 and to evaluate its possible antigenicity. The genes am254, virB9 and virB10 were

5. Referências hematológicas para a jararaca de rabo branco (Bothrops leucurus) recém capturadas da natureza
The hematological values for the specie Bothrops leucurus, recently captured from nature, were determined from blood samples of 29 snakes (11 males and 18 females). The performed hematological tests were: total red blood cell count (TRBCC), total white blood cell count (TWBCC), total trombocyte blood cell count (TTBCC); packed cell volume (PCV); hemoglobin c

6. Clinical, laboratory and epidemiological aspects of naturally acquired Babesia equi infection (Laveran, 1901) in equines from the Academia Militar das Agulhas Negras / Aspectos clínicos, laboratoriais e epidemiológicos da infecção natural por Babesia equi (Laveran, 1901) em eqüinos da Academia Militar das Agulhas Negras
This study was conducted with the purpose to evaluate the clinical, laboratory and epidemiological aspects of naturally acquired Babesia equi infection in 178 horses handled in a semi-intensive system, property of the Academia Militar das Agulhas Negras Brazilian Army, situated in the city of Resende, in the Rio de Janeiro State. Babesia equi is a species of

7. Habitat, world geographic range, and embryonic development of hosts explain the prevalence of avian hematozoa at small spatial and phylogenetic scales
The factors explaining interspecific differences in prevalences of blood parasites in birds are poorly known. We simultaneously assessed 20 social, ecological, life history, and sampling-related variables that could influence hemoparasite prevalences among diurnal birds of prey in Spain. Our results show that multiple factors are responsible for the stu

8. Competitive Enzyme-Linked Immunosorbent Assay Based on a Rhoptry-Associated Protein 1 Epitope Specifically Identifies Babesia bovis-Infected Cattle
The competitive enzyme-linked immunosorbent assay (cELISA) format has proven to be an accurate, reliable, easily standardized, and high-throughput method for detecting hemoparasite infections. In the present study, a species-specific, broadly conserved, and tandemly repeated B-cell epitope within the C terminus of the rhoptry-associated protein 1 of the hemo

9. Babesia divergens and Plasmodium falciparum Use Common Receptors, Glycophorins A and B, To Invade the Human Red Blood Cell
Babesiosis has long been recognized as an economically important disease of cattle, but only in the last 30 years has Babesia been recognized as an important pathogen in humans. Invasion of erythrocytes is an integral part of the Babesia life cycle. However, very little information is available on the molecules involved in this process, in contrast to anothe

10. Cell-mediated immune responses to Babesia bovis merozoite antigens in cattle following infection with tick-derived or cultured parasites.
Peripheral blood mononuclear cells from cattle experimentally infected with Babesia bovis were examined for parasite-specific cell-mediated immune responses. Unfractionated merozoites and soluble and membrane fractions derived from merozoites were all antigenic for immune cattle, although the membrane fraction was the most stimulatory. Cattle responded to di

11. Paternal investment affects prevalence of malaria.
Both reproduction and parasite defense can be costly, and an animal may face a trade-off between investing in offspring or in parasite defense. In contrast to the findings from nonexperimental studies that the poorly reproducing individuals are often the ones with high parasite loads, this life-history view predicts that individuals with high reproductive in

12. Detection and quantitation of Anaplasma marginale in carrier cattle by using a nucleic acid probe.
Cattle which have recovered from acute infection with Anaplasma marginale, a rickettsial hemoparasite of cattle, frequently remain persistently infected with a low-level parasitemia and serve as reservoirs for disease transmission. To fully understand the role of these carriers in disease prevalence and transmission, it is essential that low levels of parasi
