Resposta imune humoral de cäes à vacina inativada, de cérebro de camundongos lactentes, utilizada nas campanhas anti-rábicas no Brasil / Humoral immune response of dogs to the inactivated suckling mouse brain vaccine utilized in anti-rabies campaigns in Brazil

A campanha anti-rábica no Brasil é realizada anualmente utilizando a vacina de cérebro de camundongos lactentes Fuenzalida-Palacios. A resposta imune humoral de cäes vacinados durante as campanhas foi analisada objetivando avaliar se os cäes apresentavam título protetor (0,5 UI/ml), 12 meses após a vacinaçäo, e quantos deles alcançam esse título 30 dias após o reforço vacinal. Foram analisadas 341 amostras de soro de cäes domiciliados (259 do município de Säo Paulo e 82 do município de Paulínia), através da Técnica de Inibiçäo de Focos de Fluorescência Rápida. A resposta imune foi avaliada considerando o estado nutricional do animal e o número de vacinaçöes anteriores. A maioria dos cäes näo tinha título de 0,5 UI/ml após 12 meses, independentemente do estado nutricional, e a resposta humoral ao reforço vacinal mostrou-se melhor em cäes com duas ou mais vacinaçöes prévias. Säo discutidos o referencial de 0,5 UI/ml como título protetor para a espécie canina e a influência do estado nutricional e condiçäo de saúde do animal como responsável pela resposta imune humoral

Engano na administração de soro-vacinação para raiva. Emprego de esquema improvisado e sua avaliação: apresentação de um caso / An error in the administration of rabies serum vaccination. The use of an improvised schedule and its evaluation: report of a case

We report on a female patient attacked by a dog that died 4 days later, who sought treatment 11 days after the accident. A serum vaccination schedule was indicated, to be started immediately with the administration of anti-rabies serum (9 ml, corresponding to 40 IU/Kg body weight) and a series of 10 doses of vaccine applied on consecutive days plus 3 booster doses applied at 10-day intervals, according to the regulations of the Health Secretariat of the State of São Paulo. However, due to an error, 9 vaccine doses were initially applied at 3 different anatomical sites. The error was immediately discovered and it was decided to interrupt treatment for a few days and to restart and complete it later; this was done only 8 days later. Serologic follow-up by the serum-neutralization test in cell culture revealed a fully satisfactory response greatly exceeding WHO recommendations in terms of levels, precocity and duration. The patient continued to be healthy by the 240th day after the accident, when she was observed for the last time before this publication.

Immunomodulatory effect of glucan on the response to experimental antirabies vaccination

The objective of the present study was to determine the stimulatory response to antirabies vaccination promoted by glucan in mice. Glucan increased both resistance to infection and antibody titres and this effect was more evident when glucan was used at dose of 0.5 mg, administered intraperitoneally before, during and after immunization and when the challenge virus was applied to the foot-pad.
