【 摘 要 】

From 1984 to 1997 15.558 sorologic tests to leptospirosis were performed (MAT with 24 leptospires serovars) in 284 sheeps, 879 boffaloes, 983 dogs, 1.941 goats, 2.903 horses and 8.568 swines. The distribuition of animals examined by species and state were: sheeps – SP (100%); buffaloes – SP (100%); dogs – SP (80.7%), RS (0.10%), SC (0.10%) and PI (19.0%); goats – SP (33.1%), PB (63.7%) and CE (3.2%); horses – SP (79.3%), RS (9.98%), SC (0.62%), PR (2.5%), RJ (0.17%), MG (1.96%), MT (3.99%), PB (1.3%) and PI (0.03%); swines – SP (61.91%), RS (0.3%), SC (5.95%), PR (3.67%), RJ (0.88%), MG (24.38%), GO (1.12%), SE (0.2%), PE (0.90%), CE (0.34%) and MA (0.1%). From the sheeps tested, 54.5% were examined between 1996 and 97. 33.3% between 1989 and 1990 and 12.2% in the other years; buffaloes – 21.7% from 1984 to 95 and 78.83% between 1996 and 97; dogs – 16.91% from 1984 to 92 and 83.09% from 1993 to 97; goats – 6.97% from 1984 to 91 and 93.09% from 1992 to 97, althought 49% were concerning to 1992; horses – 18.1% from 84 to 90 and 81.9% from 1991 to 97; swines – 61.16% concerning 1990, 91, 95 and 96. The proportion of reactors to at least one leptospira serovar presented the following average and most frequent serovars: sheeps – 0.70% and icterohaemorrhagiae like most frequent serovar; buffaloes – 43.7% and serovars hardjo and pomona; dogs – 17.7% and serovar icterohaemorrhagiae in SP and pyrogenes in PI; goats – 4.17% and icterohaemorrhagiae and grippotyphosa in CE, icterohaemorrhagiae in PB and pyrogenes in SP; horses – 29% and serovar icterohaemorrhagiae in PR, SC, SP, RJ e MG, grippotyphosa in MT, pyrogenes in PB and patoc in RS; swines –24.46% and serovar grippotyphosa and icterohaemorrhagiae in MG, pomona in RS, pomona and icterohaemorrhagiae in PE and RJ, autumnalis in CE and icterohaemorrhagiae in GO, PR, SC e SP.
