13. Prevalência de endo e ectoparasitas em cracídeos criados em cativeiro no Parque Dois Irmãos, Recife -PE. / Prevalence of endo and ectoparasitas in Cracídeos created in captivity in the Park Dois Irmãos, Recife-PE
Entre os vários problemas sanitários que afetam as aves silvestres, as enfermidades parasitárias estão entre as mais freqüentes, podendo causar desde infecções sub-clínicas até a morte. Os endoparasitos são muito comuns em aves mantidas em cativeiro, principalmente em casos de alta densidade populacional. Os ectoparasitos provocam danos diretos que

14. Imunomodulação e ação anti-Leishmania (Viannia) braziliensis por Ouratea cuspidata (Ochnaceae) / Immunomodulation and action anti-Leishmania (Viannia) braziliensis promastigotes by Ouratea cuspidata (Ochnaceae)
Ouratea cuspidata (Ochnaceae) crude extracts were added to experimental systems containing either host macrophages, or Leishmania braziliensis promastigotes (L566). The biological effect by the use of the hexane (OCH), methanol (OCMeH) and ethyl-acetate (OCAcEt) extracts added at different concentrations: 2mg/mL; 4mg/mL; 8mg/mL, 16mg/mL e 32mg/mL. The OCMeOH

15. The study of ionizing radiation as a tool for select promastigotes forms of Leishmania amazonensis, and the immunological response in experimental models / Estudo do uso da radiação ionizante como ferramenta de seleção de formas promastigotas metacíclicas de Leishmania amazonensis e a indução de resposta imunológica em modelos experimentais
Actually, millions of people around the globe are under the risk of infection by a protozoan transmitted by a bit of a sand fly. This parasite is a Leishmania spp. This causes a wide spectrum disease, since a coetaneous disease to a visceral one. The coetaneous form is the major clinical manifestation (above 90%). The ionizing radiation, produced in a 60Co f

16. Identification of Anopheles (Nyssorhynchus) albitarsis complex species (Diptera: Culicidae) using rDNA internal transcribed spacer 2-based polymerase chain reaction primes
Anopheles (Nyssorhynchus) marajoara is a proven primary vector of malaria parasites in Northeast Brazil, and An. deaneorum is a suspected vector in Western Brazil. Both are members of the morphologically similar Albitarsis Complex, which also includes An. albitarsis and an undescribed species, An. albitarsis "B". These four species were recognized and can be

17. Haematozoan parasites of the lizard Ameiva ameiva (Teiidae) from Amazonian Brazil: a preliminary note
Three different haematozoan parasites are described in the blood of the teiid lizard Ameiva ameiva Linn. from North Brazil: one in the monocytes and the other two in erythrocytes. The leucocytic parasite is probably a species of Lainsonia Landau, 1973 (Lankesterellidae) as suggested by the presence of sporogonic stages in the internal organs, morphology of t

18. Epidemiological and clinical features of Leishmania (Viannia) braziliensis American cutaneous and mucocutaneous leishmaniasis in the State of Espírito Santo, Brazil
Between 1985 and 2000, epidemiological surveys of the American tegumentary leishmaniasis (ATL) were carried out in several rural and urban communities in Espírito Santo, Brazil. A total of 100 stocks of Leishmania (comprising isolates from both human and canine hosts with ATL) were identified by two methods of molecular characterization, using specific mono

19. Pathoecology of Chiribaya parasitism
The excavations of Chiribaya culture sites in the Osmore drainage of southern Peru focused on the recovery of information about prehistoric disease, including parasitism. The archaeologists excavated human, dog, guinea pig, and llama mummies. These mummies were analyzed for internal and external parasites. The results of the analysis and reconstruction of pr

20. Genetic diversity of Colombian sylvatic Trypanosoma cruzi isolates revealed by the ribosomal DNA
American trypanosomiasis is a common zoonosis in Colombia and Trypanosoma cruzi presents a wide distribution throughout the country. Although some studies based on enzyme electrophoresis profiles have described the population structure of the parasite, very few molecular analyses of genotipic markers have been conducted using Colombian strains. In this study

21. Caracterização de dois genes contíguos de Trypanosoma cruzi que codificam antígenos com repetições de epitopos imunodominantes / Characterization of two contiguous antigen genes of Trypanosoma cruzi presenting immunodominant repetitive domains
Characterization of two contiguous antigen genes of Trypanosoma cruzi presenting immunodominant repetitive epitopes A genomic library of T. cruzi in the vector λgt11 was screened with antitrypomastigote serum. Two clones, named B12 and B13, were isolated and shown to express proteins which contain tandemly repeated units of 20 amino acids (B12) and 12 a

23. Lysis of Plasmodium falciparum by ferriprotoporphyrin IX and a chloroquine-ferriprotoporphyrin IX complex.
Ferriprotoporphyrin IX (FP) and a chloroquine-FP complex lysed isolated Plasmodium falciparum parasites as judged by decreases in the turbidity of parasite suspensions and by ultrastructural changes. Exposure of parasite suspensions to 50 microM FP or to a complex formed from 50 microM FP and 20 MicroM chloroquine reduced the number of identifiable parasites

24. Rapid invasion of host cells by Toxoplasma requires secretion of the MIC2–M2AP adhesive protein complex
Vertebrate cells are highly susceptible to infection by obligate intracellular parasites such as Toxoplasma gondii, yet the mechanism by which these microbes breach the confines of their target cell is poorly understood. While it is thought that Toxoplasma actively invades by secreting adhesive proteins from internal organelles called micronemes, no genetic
