RESUMO
A new serovar of Leptospira interrogans was isolated from a dog in Barbados. The proposed name of the new serovar is bim, and the designated type strain is 1051. The serogroup of the new serovar is the Autumnalis serogroup. The new serovar was subsequently isolated from six patients with leptospirosis in Barbados.

Six new serovars of Leptospira interrogans were isolated from opossums (Didelphis marsupialis and Philander opossum) trapped in the Peruvian jungle. The proposed names, type strain designation, and serogroup of the serovars, respectively, were: huallaga, strain M-7, Djasiman serogroup; luis, strain M-6, Tarassovi serogroup; machiguenga, strain MMD-3, Icterohaemorrhagiae serogroup; rioja, strain MR-12, Bataviae serogroup; rupa rupa, strain M-3, Sejroe serogroup; and tingomaria, strain M-13, Cynopteri serogroup.

Among 116 stray dogs in Puerto Rico surveyed for leptospiral agglutinins, 73 (62.9%) has significant titers to one or more leptospiral serotypes. The most common serogroup identified serologically was icterohaemorrhagiae accounting for 53 (72.6%) of the infections. Although the infection rates were comparable for male and female dogs the older were found to be more frequently infected. The significance of the canine in the epidemiology of leptospirosis in Puerto Rico is probably of paramount importance due to the extensive direct and indirect contact dogs have with rats and the human population.

A hyperendemic malaria focus, found in 1973 in a secluded valley in South-eastern Peru, was restudied in 1975. Tests for antibodies to Plasmodium and Leptospira were performed on blood serum and blood slides collected at three locations on the Rio Ene and confluent streams and at two locations in the neighbouring highlands. The hyperendemic focus of P. vivax-P. malariae found at Mission Cutivirini in 1973 was confirmed in this study. Another hyperendemic focus of predominantly P. vivax was found at the village of Saoreni. Lesser amounts of malaria were found at other locations. Serology indicated past or present contact with Leptospira of from 50 to 75% of individuals at all locations. The two hyperendemic malaria foci therefore were embedded in a much larger hyperendemic focus of leptospirosis. The value of the indirect immunofluorescence test for malarial antibodies as a sero-epidemiological tool was emphasized by this study.
