%X Canine visceral leishmaniasis (CVL) is caused by the protozoan Leishmania infantum, which infects dogs and humans in many regions of Brazil. The present study involved an indirect fluorescent antibody test (IFAT) to analyze L. infantum, Ehrlichia spp., Babesia canis, Toxoplasma gondii and Neospora caninum infection rates in serum samples from 93 dogs in a rural settlement in Ilha Solteira, SP, Brazil. The seroprevalence rates of anti-L. infantum, anti-Ehrlichia, anti-B. canis, anti-T. gondii and anti-N. caninum antibodies were 37.6%, 75.3%, 72%, 47.3% and 6.4%, respectively. In addition to IFAT, direct microscopic examination of popliteal lymph node aspirates revealed 26.9% of CVL positive dogs. Serological tests revealed that 17.2% of the dogs were seropositive for a single parasite, 29% for two parasites, 33% for three, 16.1% for four, and 1.1% for five parasites, while 3.2% were seronegative for five parasites. The presence of antibodies against these parasites in serum samples from dogs confirmed their exposure to these parasites in this rural area. Because of the potential zoonotic risk of these diseases, mainly leishmaniasis, ehrlichiosis and toxoplasmosis, special attention should focus on programs for the improvement of diagnostic assays and control measures against these parasites. Leishmaniose Visceral Canina (LVC) ¨¦ causada pelo protozo¨¢rio Leishmania infantum, podendo infectar c es e humanos em v¨¢rias regi es do Brasil. O presente estudo teve por objetivo realizar a rea  o de imunofluoresc¨ºncia indireta (RIFI) para analisar os ¨ªndices de infec  o parasit¨¢ria para L. infantum, Ehrlichia spp., Babesia canis, Toxoplasma gondii e Neospora caninum, em 93 amostras de soro de c es de um assentamento rural no munic¨ªpio de Ilha Solteira, SP, Brasil. A taxa de soropreval¨ºncia de c es com anticorpos anti-L. infantum, anti-Ehrlichia, anti-B. canis, anti-T. gondii e anti-N. caninum foi de 37,6%, 75,3%, 72%, 47,3% e 6,4%, respectivamente. Pelo exame microsc¨®pico direto dos parasitas nos esfrega os de aspirados de linfonodos popl¨ªteos dos c es, a positividade para LVC foi de 26,9%. Pelos exames sorol¨®gicos, 17,2% dos c es estavam positivos com um ¨²nico parasita, 29% com dois, 33% com tr¨ºs, 16,1% com quatro e 1,1% com cinco parasitas. Al¨¦m disso, 3,2% eram soronegativos para todos os cinco agentes parasit¨¢rios. A presen a de anticorpos aos parasitos em amostras sorol¨®gicas confirmam a exposi  o dos c es ¨¤s doen as parasit¨¢rias nesse assentamento rural. Devido ao potencial risco zoon¨®tico destas doen as, principalmente leishmaniose, erliquiose e toxoplasmose
