ABSTRACT

The widespread perception of the effectiveness of applying tests based on the detection of antibodies against foot-and-mouth disease (FMD) viral non-capsid proteins (NCPs) to assess virus circulation irrespective of vaccination triggered the demand for international standards to evaluate the comparative performance of the upcoming assays against the OIE Index test developed at the Pan American Foot-and-Mouth Disease Center, PAHO/WHO. To this end, a panel was developed composed of 34 cattle sera from animals with an unambiguous exposed/infected status, covering serotypes O, A and C, obtained either under experimental conditions or from the field in regions with different epidemiological situations. Reference values in the Index test and their reproducibility in other laboratories, data on stability as well as results in four other commercial kits and one in house test were obtained. The characteristics of the panel which comprise adequate preparation following international guidelines, a broad range of antibody reactivity, proper stability and the ability to assess comparative diagnostic sensitivity, make it suitable as a reference standard to evaluate if tests equivalent to the OIE Index method are used in support of FMD control programs and by trading partners, and also whether they maintain their standards of diagnostic performance.

ABSTRACT

Através de estudo comparativo, objetivou-se avaliar a eficiência anti-helmíntica de pamoato de pirantel, isolado ou associado ao triclorfon, no controle de estrongilídeos de equinos da raça Puro Sangue Inglês. As coproculturas realizadas antes e após os tratamentos levaram consistentemente ao encontro de populaçöes puras de ciatostomíneos com oito células intestinais. As reduçöes de ovos por grama de fezes foram avaliadas do 7§ ao 45§ dias pós-tratamento. Comparando os valores médios de OPG dos equinos tratados com pamoato de pirantel (13,2 mg/kg) associado ao triclorfon (30 mg/kg) e com pamoato de pirantel isolado (13,2 mg/kg), observou-se diferença näo significante (P<0,05) ao longo do experimento, verificando-se, 7 dias após o tratamento, reduçöes médias de OPG de quase 100 por cento e, do 7§ ao 20§ dias, reduçöes ainda superiores a 90 por cento. Os resultados indicam que os dois produtos säo eficazes na reduçäo de ovos por grama de fezes de ciatostomíneos de equinos mantidos sob condiçöes a campo

ABSTRACT

Preparou-se uma lepromina do tipo bacilar, a uma concentração de 2%/oo, com bacilos de Hansen obtidos do baço e f¡gado do cadaver de um doente lepromatoso. Os estudos feitos nos pacientes lepromatosos, tuberculóides e indiferenciados, demonstraram que esta lepromina provoca reações precoces e tardias que coincidem com as reações clássicas que se observam com a lepromina bacilar preparada com nódulos cutâneos. Esta fonte de germes permitir  preparar lepromina em quentidade muito maior do que normalmente se conseguia e torna possível um melhor abastecimento deste produto aos serviços regionais de controle de doentes, comunicantes e suspeitos, em uma campanha antileprosa que atinja amplas zonas endêmicas.
