13. Leptospirose letal aguda em Hamster: caracterização de perfis bioquímicos, histopatológicos e celulares renais, relacionada a ensaios terapêuticos / Reversal of renal tubule transporter down-regulation during severe leptospirosis with antimicrobial therapy
Leptospirosis is a zoonosis of worldwide distribution. About 5-10% of all human infections presents with severe forms. Weils syndrome, the most common presentation of severe forms of leptospirosis, may courses either as a single monophasic disease or as a disease with prolonged course, characterized by a combination of hemorrhage, particularly in the lung, r

14. Avaliação da resposta imune em cães após imunização com dois antígenos recombinantes de Leishmania chagasi/L. infantum em associação a interleucina 12 (il-12) canina. / Immune response of dogs immunized with two Leishmania chagasi/L. infantum recombinant antigens in combination with recombinant canine 12 (il-12).
Visando contribuir para o desenvolvimento de uma vacina contra leishmaniose visceral canina, no presente trabalho, foi avaliada a resposta imune de cães após a imunização com dois antígenos recombinantes de L. chagasi/L. infantum (denominados Lc9 e Lc13) misturados a saponina em associação ou não com plasmídeo codificando IL-12 canina de cadeia úni

15. Anaplasma marginale : análise da variabilidade do gene msp1 a e avaliação imunogênica da vacina de DNA contendo genes para MSP1a, MSP1b e MSP5 em camundongos BALB/c
Anaplasma marginale is an important tick-transmitted rickettsial pathogen of cattle that invades and multiplies within erythrocytes, causing severe hemolytic anemia during acute infection. Immunization with purified outer membrane proteins (OMP) induces protection against acute A. marginale disease. Of 21 OMP described six major surface proteins (MSPs 1a, 1b

16. Infecção por Toxoplasma gondii e Neospora caninum em cães e lobos-guará: soroepidemiologia e imunodiagnóstico / Infecção por Toxoplasma gondii e Neospora caninum em cães e lobos-guará: soroepidemiologia e imunodiagnóstico
Toxoplasma gondii and Neospora caninum are two closely related apicomplexan parasites, even though phylogenetic, ultrastructural, antigenic and biological differences have been already described. Seroepidemiological studies have demonstrated that T. gondii infection is often in domestic and sylvatic canids, whereas N. caninum infection is less common, but it

17. Humoral response to low molecular weight antigens of Mycobacterium tuberculosis by tuberculosis patients and contacts
Much effort has been devoted to the identification of immunologically important antigens of Mycobacterium tuberculosis and to the combination of target antigens to which antibodies from serum of tuberculous patients could react specifically. We searched for IgG antibodies specific for antigens of 45 to 6 kDa obtained after sonication of the well-characterize

18. Combined use of Western blot/ELISA to improve the serological diagnosis of human tuberculosis
Two recombinant antigens and a crude bacterial antigen of a wild M. tuberculosis strain were used to detect specific IgG antibodies in sera from 52 patients with pulmonary tuberculosis, confirmed by an acid-fast smear and serum culture of these patients and that of 25 contacts. The patients were not infected with HIV. We evaluated the sensitivity and specifi

19. Study of the antibody response against Mycobacterium tuberculosis antigens in Warao Amerindian children in Venezuela
This study was aimed at investigating alternate methods for serodiagnosis of tuberculosis (TB), which are needed because bacteriologic diagnosis of childhood TB is difficult. A selection of 80 serum and saliva samples were tested from Warao indigenous children under 15 years of age; 34 high TB suspects (28 positive and 6 negative for the tuberculin skin test

20. Induction of oral tolerance and the effect of interleukin-4 on murine skin allograft rejection
We studied the effect of oral and portal vein administration of alloantigens on mouse skin allograft survival. Graft receptor BALB/c mice received spleen cells (30, 90, 150 or 375 x 10(6)) from donor C57BL/6 mice intragastrically on three successive days, starting seven days before the skin graft. Allograft survival was significantly increased with the feedi

21. Protective immunity of single and multi-antigen DNA vaccines against schistosomiasis
We evaluated the usefulness of the combination of three plasmids encoding tegumental (pECL and pSM14) and muscular (pIRV5) antigens of the Schistosoma mansoni on improving the protective immunity over the use of a single antigen as DNA vaccines. Female BALB/c mice were inoculated twice with 25 µg DNA plasmid within two weeks interval. The challenge was perf

22. Laboratory diagnosis of Schistosomiasis in areas of low transmission: a review of a line of research
After 57 years of successful control of schistosomiasis in Venezuela, the prevalence and intensity of infection have declined. Approximately 80% of the individuals eliminate less than 100 eggs/g of stools, therefore morbidity is mild and the majority are asymptomatic. The sensitivity of Kato-Katz decreases to approximately 60%. Available serological methods

23. Occurrence, distribution, and associations of O and H serogroups, colonization factor antigens, and toxins of enterotoxigenic Escherichia coli.
Enterotoxigenic Escherichia coli (ETEC) is a leading cause of infectious diarrhea worldwide. Four categories of antigens have been commonly studied: O serogroup, H serogroup, colonization factor antigens (CFA), and toxins. A database has been complied from published reports of nearly 1,000 ETEC isolates from 18 locations and analyzed to determine the occurre

24. Evaluation of a Combination Rapid Immunoassay for Detection of Giardia and Cryptosporidium Antigens
A combination cassette format nonenzymatic rapid immunoassay for detection of Giardia and Cryptosporidium antigens was evaluated by using 556 patient stool specimens from three clinical laboratories. This assay (Genzyme Diagnostics Contrast Giardia/Cryptosporidium), which can be used with fresh or formalin-fixed specimens, had unadjusted sensitivities and sp
