Ocorrência de aglutininas anti- Leptospira spp. em feirantes e cães de dez feiras do município de São Luís-MA

Abstract

Leptospirosis is an illness caused by an Espiroqueta of the genus and has serious consequences for human and animal`s health. The infection occurs by different serovars that can be maintained for a long period, in one or more hosts with different levels of adaptation. The studying was realized, from December 2006 to May 2007, objetiving to verify the occurrence of agglutinins anti# spp. and the more frequent serovars in marketers and dogs of ten conventional fairs of São Luís town of MA. The technique used in this research was Microscopic Agglutination (SAM) with the use of 20 live antigens of spp. It was examined about 163 samples of the marketers, 103 (63.19%) were reagents, being most frequently the serovars Icterohaemorrhagiae, 32 (11.03%), Sensot, 27 (9.31%), Patoc, 25 (8.62%) and Butembo, 22 (7.59%). The maximum title was 200 for serovars Castellonis, Icterohaemorrhagiae, Pomona and Sensot. Among 38 samples`s dogs that has been examined, 29 (76.32%) were reagents and the serovars most frequent were: Icterohaemorrhagiae 13 (10.25%), Pomona, 12 (9.45%), Hardjo, ten (7.87%), Castellonis, nine (7.08%) and Butembo, Canicola, Whitcombi and Copenhageni, eight (6.29%). It was verified the title of 400 to serovars Cynopteri and Pyrogenes and 200 to Cynopteri, Icterohaemorrhagiae, Panama, Pyrogenes, Hardjo and Shermani. The others serovars reacted with title maximum of 100. It was important to emphasize that the fairs with 21 (12, 88%), with 18 (11, 04%), e with 14 (8, 59%) were those that showed higher frequencies in marketers, and this last one presented 100.00% the samples reagents. While the fairs with seven (18, 42%) followed by fairs , and with four (10, 53%) showed higher frequencies in dogs. The fairs , , and had been presented 100.00% of the samples reagents. It wasn’t verified expressive associations between the variables studied and the frequencies of reagents observed (p> 0.05)
