Leptospirosis en el ganado y matarifes de Tumbes, Peru

Abstract

Agglutination-lysis tests and kidney cultures in Vervoorst's medium has been used to investigate the prevalence of leptospirosis in 98 swine from the department of Tumbes, Peru and 202 cattle (110 from the department of Tubes and 92 from Ecuador) slaughtered in the abbatoir of Tumbes city. The main results were:

1) Out of 98 swine kidney cultures four were positive, three were identified as pomona and one as canicola. Out of 109 kidney cultures of cattle from Tumbes, one strain was isolated (V-42) and identified as a new serotype of Leptospira. None of the 92 kidney cultures of cattle from Ecuador was positive

2) Out of 94 swine sera, 22 (23.4 percent) were positive, most of them to pomona. Out of 110 sera of cattle from Tumbes, 32 (29.2 percent) were positive, most of them to pomona and sejroe-hebdomadis. Out of 92 sera of cattle from Ecuador, 25 (27.2 percent) were positive, most them to sejroe-hebdomadis

3) Out of 103 serological reactions using the strain of Leptospira V-42 as antigen, two sera were positive, one of swine and other of cattle from Tumbes

These results, added to those obtained by other investigators, would show that leptospirosis is a zoonosis widespread in Peru and also that it is urgent to make an extensive national investigation to know, as exactly as possible, the epidemiology of leptospirosis in this country. In this investigation the use of at least one sero. ...(AU)
