1. The prevalence of enterotoxigenic E. coli isolated from the stools of children aged 0-10 years with diarrhea in mid-anatolia region, Turkey
The stool samples from 245 patients with diarrhea were tested for heat labile toxin (LT) and heat stable toxins (ST) by passive latex agglutination and enzyme immunoassay methods respectively. Twelve (4.9%) enterotoxigenic E. Coli ETEC strains were isolated. Five strains (2%) expressed ST, and 7 (2.8%) expressed LT.

2. ENAGIS-MAY: an indirect agglutination assay to detect immunoglobulins against the Mayaro virus in whole blood / ENAGIS-MAY: uma proposta de ensaio de aglutinação indireta para detectar no sangue imunoglobulinas contra o vírus Mayaro
O vírus Mayaro (MAYV) foi isolado inicialmente em Trinidad em 1954. No Brasil foi isolado em 1955 durante surto ocorrido no estado do Pará. Surtos têm sido descritos nas regiões da floresta amazônica, no norte do Brasil, onde pode ser considerado endêmico, e cujo ecossistema tem sido profundamente perturbado. Os sintomas causados pela infecção do MAY

3. Ocorrência de Staphylococcus aureus e Escherichia coli O157:H7 em rebanhos leiteiros do Estado de São Paulo / Staphylococcus aureus and Escherichia coli O157: H7 occurrence in dairy herds located in São Paulo State
The aim of this study was to verify the occurrence of S. aureus and E. coli O157: H7 in the milk from dairy cows with subclinical mastitis and in the bulk milk from 42 dairy farms located in two regions of São Paulo State (Region 1: São Carlos, Region 2: Ribeirão Preto). Among the S. aureus strains isolated, the aim was to identify the toxin producers and

4. Active and passive immunity in swine vaccinated against leptospirosis. Use of an experimental subunit vaccine and two commercial whole culture bacterins / Imunidade ativa e passiva em suínos vacinados contra a leptospirose. Emprego de vacina experimental de subunidade e duas bacterinas comerciais de bactérias completas
It was evaluated the performance of a subunit and whole culture bacterin vaccines against leptospirosis in sows by the analysis of agglutinating and neutralizing antibodies level. The intensity and duration of passive immunity in the offspring and active immunity in sows were investigated with microscopic agglutination test (MAT) and leptospira growth inhibi

5. "Contribuição ao imunodiagnóstico da leptospirose humana: ênfase ao uso de anticorpos monoclonais" / Contribution to the immunodiagnosis of human leptospirosis: emphasis to monoclonal antibodies.
The best serological test for leptospirosis laboratory diagnosis remains the microscopic agglutination test (MAT). Because of the complexity of MAT, we have been developed some rapid screening tests for leptospiral antibodies detection in the acute phase of infection. In the decade of 80, a passive hemagglutination test employing polysaccharide fractions of

6. COMPORTAMENTO DE ESTAFILOCOCOS COAGULASE NEGATIVOS PAUCIPRODUTORES DE ENTEROTOXINAS, EM ALIMENTOS EXPERIMENTALMENTE INOCULADOS
Linhagens de estafilococos coagulase negativos e pauciprodutores de enterotoxina de A a E, com capacidade de síntese variando de 1,4 a 16ng/mL oriundas de sítios anatômicos de cabras sadias, procedentes da Espanha, foram estudadas com o intuito de se avaliar a capacidade de desenvolvimento e produção de enterotoxina estafilocócica ("SE"), em alimentos

7. Estafilococos coagulase negativos pauciprodutores de enterotoxinas e relato de um surto por especie coagulase positiva
Linhagens de estafilococos coagulase negativos e pauciprodutores de enterotoxinas de A a E, com capacidade de síntese variando de 1,4 a 16,8ng/mL oriundas de sítios anatômicos de cabras sadias, procedentes da Espanha, foram estudadas com o intuito de se avaliar comparativamente desenvolvimento e quantidade de enterotoxina estafilocócica ("SE") produzida,

8. Comparison of enzyme-linked immunosorbent assay, hemagglutination inhibition, and passive latex agglutination for determination of rubella immune status.
Hemagglutination inhibition, enzyme-linked immunosorbent assay (ELISA), and passive latex agglutination were used to test 495 human serum samples for determination of rubella immunity. Overall agreements for immune status were as follows: hemagglutination inhibition versus ELISA, 94.7% (469 of 495); hemagglutination inhibition versus passive latex agglutinat

9. Evaluation of passive bacterial agglutination for the diagnosis of typhoid fever.
We evaluated the reliability of a passive bacterial agglutination test to detect Salmonella typhi somatic antigen(s) in the sera of patients with typhoid fever. It was positive in 32 of 33 bacteriologically proven typhoid fever cases. Among 13 patients with a presumptive diagnosis of typhoid fever, 11 were positive by passive bacterial agglutination. The ser

10. Evaluation of a reversed passive latex agglutination test for detection of Escherichia coli heat-labile toxin in culture supernatants.
One hundred strains of Escherichia coli were tested for the production of the heat-labile enterotoxin by the Y1 adrenal cell test and a commercially available reversed passive latex agglutination test. The strains were grown in Casamino Acids-yeast extract broth, and filtered culture supernatants were tested for the presence of heat-labile enterotoxin. There

11. Detection of Legionella antigenuria by reverse passive agglutination.
A reverse passive agglutination method was developed to detect soluble antigens of Legionella spp. By this method Legionella antigens were detected in urine specimens from 14 of 15 antigenuric patients with clinically diagnosed Legionnaires disease and in none of 263 urine samples from healthy subjects or patients with urinary tract infections. Intra-genus c

12. Sensitivity of passive bacterial agglutination for detection of hepatitis B surface antigen.
The sensitivity of passive bacterial agglutination (PBA), i.e., the agglutination of Staphylococcus aureus coated with antibodies to hepatitis B surface antigen by hepatitis B surface antigen, was assessed by testing reference panel no. 3A sera (Bureau of Biologics, U.S. Food and Drug Administration). Of the 23 samples containing hepatitis B surface antigen,
