Comparative trial of the canine parvovirus, canine distemper virus and canine adenovirus type 2 fractions of two commercially available modified live vaccines.

The results of vaccinating two groups of puppies with commercial vaccines, both of which claimed to provide adequate protection with a final vaccination at 10 weeks of age, were compared. Groups of 19 and 20 puppies with similar titres of maternally derived antibodies against canine parvovirus (cpv), canine distemper virus (cdv) and canine adenovirus type 2 (cav-2) at four weeks of age were vaccinated at six and 10 weeks of age and their responses to each vaccination were measured by comparing the titres against cpv, cdv and cav-2 in the serum samples taken immediately before the vaccination and four weeks later. After the vaccination at six weeks of age, all 19 of the puppies in group 1 had responded to cpv and cdv, and 14 had responded to cav-2; in group 2, 17 of the 20 had responded to cpv, 19 to cdv and 15 to cav-2. In both groups the puppies that did not respond to the first vaccination had responded serologically to cpv, cdv and cav-2 at 10 weeks of age.

Brazilian spotted fever in Espirito Santo, Brazil: description of a focus of infection in a new endemic region.

Although Brazilian spotted fever is known to occur in several adjacent states, infection with spotted fever group (SFG) rickettsiae has not previously been documented in the Brazilian state of Espirito Santo. We report a cluster of two proven and four suspected cases of Brazilian spotted fever in a small valley near Colatina, Espirito Santo. Four patients died without confirmatory serologic or pathologic studies. The two surviving patients had serologic and/or pathologic evidence of infection with SFG rickettsiae. Results of a survey done in 1991 confirmed the presence of antibodies reactive with SFG rickettsiae in the serum of dogs living in this region. Two of 25 dogs had elevated microimmunofluorescent antibody titers (1:64 and 1:256). Both seropositive dogs were pets of the index cases and lived in the valley where all six human cases were presumed to have acquired their infections. These cases and the results of the canine serosurvey suggest that a focus of virulent disease exists in an area not previously known to be endemic for SFG rickettsiae.
