“…in dogs and their geographical distribution are related to the distribution of their vector species (Solano-Gallego and Baneth, 2011). Transmission can also occur from dog to dog through bite ( Jefferies et al, 2007) and transplacental transmission (Fukumoto et al, 2005).…”

“…The epidemiology of B. conradae transmission is still not fully understood; although the organism was found in the salivary glands of Rhipicephalus sanguineus ticks, attempts to transmit infection using ticks were unsuccessful 4. Vertical transmission has been proposed, as is seen in other canine babesial infections,5, 6 and a recent case series supported this as 8 dogs were descendants of a single infected dog 7. In one study, hemolytic anemia was described in 12 affected companion dogs from Los Angeles County and dogs were successfully treated with atovaquone and azithromycin.…”

Background Babesia conradae is an intraerythrocytic piroplasm infecting dogs in the southern United States. Ticks have been suspected, but unproven, as vectors. We identified B. conradae and other blood‐borne pathogens in 2 kennels of sighthounds with a history of coyote fighting.ObjectivesTo examine clinicopathologic abnormalities associated with B. conradae infection, risk factors for infection, and the prevalence of coinfections with other blood‐borne pathogens.AnimalsFifty‐five Greyhounds and Greyhound mixesMethodsBlood samples were collected from each dog for CBC, serum biochemistry panel, conventional and real‐time PCR assays (Babesia spp., hemoplasmas, Ehrlichia canis, Bartonella spp., Anaplasma spp., and Rickettsia spp.), vector‐borne pathogen ELISA, and immunofluorescent serology and culture for Bartonella spp and Francisella tularensis sero‐agglutination test. Associations between B. conradae infection and coyote fighting, age and laboratory abnormalities were investigated.ResultsTwenty‐nine dogs were PCR‐positive for B. conradae. Of these, 16 were PCR‐positive for other vector‐borne organisms including Mycoplasma haemocanis, “Candidatus Mycoplasma haematoparvum,” E. canis, and a Hepatozoon felis‐like organism. Twelve of the 20 dogs tested for seroreactivity to Bartonella spp. antigens were positive, but none were seropositive for tularemia. Infection with B. conradae was associated with a history of aggressive interactions with coyotes; lower hematocrit, leukocyte count, MCHC, platelet count and serum albumin concentration; and higher MCV, MPV, and serum globulin concentration.Conclusions and Clinical Importance Babesia conradae infection should be considered in dogs with anemia, leukopenia, thrombocytopenia, hypoalbuminemia and hyperglobulinemia. As with B. gibsoni, aggressive interactions with other canids may play a role in B. conradae transmission.

“…The transplacental transmission of B. gibsoni has been experimentally demonstrated in a bitch that delivered a litter of one stillborn and four live pups (Fukumoto et al 2005). These four pups died of congenital babesiosis between Days 14 and 39 post-birth.…”

The present study reports the possible vertical transmission of Babesia canis canis from an infected bitch to her puppies. The study concerns a bitch that had developed babesiosis in week seven of pregnancy and her litter, three puppies that exhibited symptoms of the disease in Weeks 8-9 post-partum. In all animals, the infection with protozoa was confirmed by the results of a PCR blood test. The identity of the nucleotide sequences of the amplified fragment of the gene (18S RNA) isolated from the blood of the puppies and the bitch was 100%, which indicates that all the dogs were infected with the same strain of protozoa. This result, together with the exclusion of other possible routes of babesiosis transmission in puppies, suggests that they were infected with Babesia canis canis in utero.
