37. Efficacy of an enzyme-linked immunosorbent assay as a diagnostic tool for schistosomiasis mansoni in individuals with low worm burden
IgM-ELISA is an immunoenzymatic method useful for detection of IgM antibodies against a fraction of Schistosoma mansoni adult worm antigen (AWA) that is soluble in trichloroacetic acid (AWA-TCA). This method was applied to three groups of individuals with different clinical and epidemiological characteristics, and the results compared with those obtained by

38. Evaluation of enzyme-linked immunosorbent assay using crude Leishmania and recombinant antigens as a diagnostic marker for canine visceral leishmaniasis
The performances of ELISA assays with different antigen preparations, such as Leishmania amazonensis or L. chagasi lysates and the recombinant antigens rK-39 and rK-26, were compared using sera or eluates from dried blood collected on filter paper to detect anti-Leishmania antibodies in dogs from a visceral leishmaniasis-endemic area in Brazil. Of 115 IFAT-r

39. Dengue: a review of the laboratory tests a clinician must know to achieve a correct diagnosis
Dengue is the most important disease caused by an arbovirus (1, 2, 3 and 4 serotypes) worldwide, especially in the tropical and sub-tropical regions. Its clinical manifestations range from asymptomatic infections to a severe disease characterized by hemorrhage and shock. The incidence of dengue virus activity in the Americas has substantially increased from

40. Cytokine profile and nitric oxide levels in sera from patients with brucellosis
The aims of this study were to investigate the serum levels of some cytokines [tumor necrosis factor-alpha (TNF-alpha), interleukin 1ß (IL-1ß), IL-2R, IL-6, and IL-8] and nitric oxide (NO) levels in patients with untreated brucellosis and to test the correlation of these parameters with each other. The study was conducted on 67 subjects, 37 patients with b

41. 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

42. ESTUDO DA INFECÇÃO E DOENÇA NO CÃO (Canis familiares) POR Leishmania (Leishmania) chagasi EM UMA ÁREA ENDÊMICA NA ILHA DE SÃO LUÍS-MARANHÃO, BRASIL / STUDY OF INFECTION AND DISEASE IN DOG (Canis family) BY Leishmania (Leishmania) chagasi in an endemic area on the island of St. Louis-Maranhão, Brazil
A cohort prospective study was carried with 350 dogs of various ages at localities Vila Nova and Bom Viver in the municipality of Raposa-MA, from March of 2002 to December of 2003. The objective is to avaluate the behavior of L. (L.) chagasi infection. The chosen areas are a result of the disordered occupation process, contributing with 60% of LVH and LVC ca

44. Utilidade da determinação da avidez dos anticorpos IgG anti-citomegalovirus humano (HCMV) para o imunodiagnostico da citomegalovirose
The infection caused by human cytomegalovirus (HCMV) is generally asymptomatic or is associated with mild non-specific clinical symptoms in immunocompetent subjects. The virus can, however, cause serious illness in congenitally infected infants and in immunocompromised patients. The serological diagnosis of a recently acquired HCMV infection is usually based

45. Determinação serica de marcadores de fibrose hepatica em portadores de esquistossomose mansoni : avaliação de colageno tipo IV e laminina
The aim of this study was to evaluate liver fibrosis in schistosomiasis mansoni, measunng serum levels of type IV collagen and laminin, components of the basal membrane. Eighty-two individuals were studied, 64 of them presenting schistosomiasis and 18 as normal controls. In schistosomiasis, 18 patients the presented intestinal form, 17 hepatointestinal, 12 c

46. Otimização da nested-PCR em turbo unico na detecção do RNA-HCV
In the present study a methodology was optimized to a nested PCR in single tube for the detection of RNA-HCV. The sequences of primers were chosen allowing different optimum annealing temperature between the first and second PCR reaction in single tube. PCR conditions were established using an control produced by amplification of 5 NCR from genome that is hi

48. Associação de acido clavulanico a cefalosporinas frente a Staphylococus aureus produtores de beta-lactamase
Since the 40 s decade, with the coming of the clinical chemotherapy, there are already reports of bacterial resistance to drugs. This resistance is preoccupying, since it becomes more and more difficult the treatment certain infections associated to the those microrganisms. Countless attempts take place in the sense of finding new drugs or associations, or s
