“…In the 1920s, organisms resembling B. bacilliformis were seen in association with erythrocytes of rodents and dogs, and these organisms were also named Bartonella 20,21 . However, it became apparent that these organisms differed from B. bacilliformis in that they could not be cultured in the laboratory, and they usually caused disease in splenectomized animals.…”

Cats presenting to emergency/critical care specialists with hemolytic anemia should be tested using polymerase chain reaction assays for hemotropic mycoplasmas before instituting antimicrobial therapy. Positive test results for M. haemofelis suggest involvement of this organism in hemolytic anemia. Other differential diagnoses for hemolytic anemia should be considered in cats testing positive for 'Candidatus Mycoplasma turicensis' and 'Candidatus Mycoplasma haemominutum,' because the presence of these organisms is not always associated with anemia. Blood from infected cats should be handled with care because of the potential zoonotic nature of this infection.

“…5 To date, the only hemoplasma affecting dogs that has been identified worldwide is M haemocanis (previously Haemobartonella canis), 7 which was first reported in 1928. 6 Via light microscopy, M haemocanis appears as rods, rings, or cocci on the surface of erythrocytes of dogs, characteristically forming long chains on the erythrocyte surface (Fig 1). After IV injection of the organism in dogs, the incubation period may range from days to more than 2 weeks.…”

“…After IV injection of the organism in dogs, the incubation period may range from days to more than 2 weeks. 6,[8][9][10][11] Chronic, subclinical infection with M haemocanis may develop in immunocompetent dogs, which may subsequently develop signs of hemolytic anemia after undergoing splenectomy. Disease that develops in dogs in association with M haemocanis infection may be acute, severe, fatal, or chronic with recurrent bouts of anemia and parasitemia.…”

A 3-year-old sexually intact male Bull Mastiff underwent splenectomy for splenic thrombosis; prior to and after splenectomy, multiple blood transfusions were administered. Two weeks after the procedure, T-cell lymphoproliferative disease was diagnosed. Treatment with prednisone and chlorambucil was initiated, and 2 weeks later, cytologic examination of a blood smear revealed small (0.3 microm), coccoid basophilic bodies on the surface of approximately 70% of the RBCs. Morphologically, these resembled "Candidatus Mycoplasma haemominutum." A polymerase chain reaction assay was used to amplify a partial 16S rRNA sequence in blood obtained from the dog; the product was sequenced and compared with 16S rRNA gene sequences of other hemotropic mycoplasmas. The sequence was 98% homologous to that of "Candidatus M haemominutum", but only 77% homologous to that of M haemocanis and M haemofelis.

“…coccoides infections by infec- tious agents (Riley 1964) and by splenectomy (Thurston 1954) Splencctomy has also been shown to precipitate a patent parasitacmia in H . canis by Kikuth (1928), although non-patent infections which can causc a sub-clinical anaemia in intact dogs have also been recorded (Weinman 1944 ) . Spontaneous haemobartonellosis has been reported in intact (Benjamin and Lumb 1959) and splenectomised (Brody and Schalm 1963) dogs.…”

IntroductioiiThe cxistence of Huemobartonella canis in splenectomiscd dogs has been observed in the USA, but to datc has not been recorded in Australia.H. cunk is a small organism which parasitises thc erythrocyte envelope, but does not penetrate it. According to Schalm (1965) the organism is non-pathogenic to the intact dog, but upon splenectomy, a clinical anaemia is often produced.A cloccly rclated organism, Haemohartonella felis, which causes clinical anaemia in intact cats has also been reported in Australia (Manusu 1961(Manusu , 1962. This paper reports the finding of H . canis in a splenectomised dog during Babesiu canis isolation studies. B. canis has already been reported in Australia by Hill and Bolton (1966). Materials and MethodsFive millilitres of blood were collected from cach of ten dogs and pooled. 20 ml of this blood was then injected into a recipient dog, splenectoniised four days earlier. The donor dogs werc incumbents of the Yeronga Dog Refuge in Brisbane.Capillary blood was collected from the ear daily for one week prior to and for many days aftcr splenectomy. Thin films were prepared and stained with Giemsa stain. Each film was examined for 20 minutes under oil immersion. Rectal temperatures werc recorded daily. Results 6. cmis was first observed in capillary blood films two days after inoculation. These parasites rapidly increased in number, reaching a pcak level of about one infected erythrocyte per two oil immersion fields six days after infection.H . canis was first noticed in low numbcrs eight days after infection. This parasite rapidly increased in number until about 95% of crythrocytes were parasitised two days later. During this 'Present address: Division of Animal Health, CSIKO 12rrng Pdrket 1,abnratories. Indoorooyilly. Queensland. A u.rtralirin Veterinary Journal, Vol. 47, April, 1971 period B. canis declined to barely detectable levels. The H . canis parasitaemia persisted and fluctuated for 20 days, with four peaks, each about 5 days apart. Three peaks were manifested by B . caizis each corresponding to a period of decline in the H . canis parasitaemia. The numbers of B. canis declined rapidly to be followed by a further peak by H . canis. After this period both parasites were no longer detectable, and the experiment was terminated.H . canis was quite pleomorphic, occurring mainly as rounded organisms 0. 2-0.5 microns ( p ) in diameter, and as rings from 0.4-0.8p in diameter. Rods and dumbbell-shaped organisms were infrequent. Generally the rounded (coccoid) organisms were in chains attached to the erythrocyte surface, but ring-forms were usually single and often free in the plasma (see Figure 1 ) .An anaemia became apparent during the course of the infection, but did not appear to be severe and was not further studied. The animal appeared to be healthy at all times, although its temperature rose about 1 .O°C with each H . canis peak, with a subsequent transient depression of the animal. DiscussionThe identification of H . cmis has been based on the description of Philip (19...
