Résumé
E. canis infection of the canine cell line DH82 is a routine in studies with this bacteria. A protocol for isolation of host cell free bacteria was developed based on the use of glass beads. Improvement of infection with E. canis isolated by this method was detected by real-time PCR.

The partial DNA sequences of the 18S rRNA gene of Babesia canis and the 16S rRNA gene of Ehrlichia canis detected in dogs from Ribeirão Preto, Brazil, were compared to sequences from other strains deposited in GenBank. The E. canis strain circulating in Ribeirão Preto is identical to other strains previously detected in the region, whereas the subspecies Babesia canis vogeli is the main Babesia strain circulating in dogs from Ribeirão Preto.
As sequências parciais dos genes RNAr 18S de Babesia canis e RNAr 16S e Ehrlichiacanis detectados em cães de Ribeirão Preto, Brasil, foram comparadas à sequências de outras linhagens depositadas no GeneBank. A linhagem de E. canis circulando em Ribeirão Preto é idêntica a outras detectadas previamente na região, enquanto a sub-espécie B. canis vogeli é a principal linhagem de Babesia circulando em cães de Ribeirão Preto.

Comparison of the partial DNA sequence of the 16S rRNA gene of Anaplasma platys detected in dogs from Ribeirão Preto, Brazil, to sequences of other strains previously deposited in GenBank showed that there are at least three A. platys strains circulating in South America.
A comparação de sequências parciais do gene 16S RNAr de Anaplasma platys detectadas em cães de Ribeirão Preto, Brasil, com sequências de outras linhagens previamente depositadas no GenBank indicam que existem pelo menos três linhagens de A. platys circulando na América do Sul.
