“…35 Blood smear evaluation is insensitive for diagnosis and also lacks specificity, and thus the diagnostic test of choice for screening blood donors is PCR. PCR testing for 'Candidatus Mycoplasma haemominutum' (which may survive for a week in stored blood 35 ) and 'Candidatus Mycoplasma turicensis' can also be considered; however, as these agents are of lower pathogenicity, 36 donors may not be excluded if positive for these organisms if the donor pool is very limited. Ideally, how ever, cats should be negative for these agents, too.…”

Practical relevance: Blood and blood products are increasingly available for practitioners to use in the management of haematological conditions, and can be lifesaving and therapeutically useful for patients with anaemia and/or coagulopathies. It is important for feline healthcare that donors are selected appropriately, and transfusions of blood or blood products are given to recipients that will benefit from them. Complications can occur, but can be largely avoided with careful donor management and recipient selection, understanding of blood type compatibility, and transfusion monitoring. Clinical challenges: Feline blood transfusion, while potentially a lifesaving procedure, can also be detrimental to donor and recipient without precautions. Cats have naturally occurring alloantibodies to red cell antigens and severe reactions can occur with type-mismatched transfusions. Blood transfusions can also transmit infectious agents to the recipient, so donor testing is essential. Finally, donors must be in good health, and sedated as appropriate, with blood collected in a safe and sterile fashion to optimise the benefit to recipients. Transfusion reactions are possible and can be mild to severe in nature. Autologous blood transfusions and xenotransfusions may be considered in certain situations. Evidence base: These Guidelines have been created by a panel of authors convened by the International Society of Feline Medicine (ISFM), based on available literature. They are aimed at general practitioners to provide a practical guide to blood typing, cross-matching, and blood collection and administration.

“… 1 , 3 Ctenocephalides felis is the principal arthropod vector for multiple Bartonella species (including Bh , Bk and Bc ). 1 , 4 , 5 Disease expression following Bh infection is largely dependent on host immunocompetence, the presence of comorbidities or coinfections, and strain virulence. After infection with a host-adapted Bartonella species, healthy cats commonly experience subclinical bacteremia that persists for months to years.…”

Case summary A 1-year-old male intact domestic shorthair cat was evaluated for acute onset non-weightbearing left forelimb lameness and generalized peripheral lymphadenopathy. CT identified a monostotic aggressive bone lesion with an incomplete fracture of the left radial metaphysis. Bone aspirates yielded osteoblasts with minimal nuclear atypia. Abdominal ultrasound revealed a nodular spleen and lymphadenopathy; cytologically, both contained lymphoid hyperplasia. A urine histoplasma antigen test was negative. Bartonella henselae and Mycoplasma haemominutum DNA was amplified by PCR from peripheral blood. Indirect immunofluorescence documented strong B henselae immunoreactivity, with lower Bartonella vinsonii subspecies berkhoffii and Bartonella koehlerae antibody titers. After the administration of doxycycline and pradofloxacin for suspected Bartonella -induced osteomyelitis, lameness resolved rapidly. Six-week post-treatment radiographs identified healing of the affected bone, and Bartonella species enrichment blood culture was negative. B henselae antibody titers decreased four-fold over a year, supporting seroreversion. Relevance and novel information B henselae is a flea-transmitted, host-adapted species, not previously implicated as a cause of osteomyelitis in cats. B henselae subclinical bacteremia is highly prevalent among cats; however, bacteremia has been associated with lymphadenopathy and febrile illness in cats. This report describes a unique clinical presentation in association with B henselae infection in a cat.

“…Three haemoplasmas (i.e. Mycoplasma haemofelis , “ Candidatus Mycoplasma haemominutum”, and “ Candidatus Mycoplasma turicensis”) are mostly found infecting cats ( Barker, 2019 ; Do et al., 2020 ), whereas Mycoplasma haemocanis and “ Candidatus Mycoplasma haematoparvum” are commonly found in dogs ( Huggins et al., 2019 ; Soto et al., 2017 ). The natural transmission routes of haemoplasmas in dogs and cats remain unclear, though the vector competence of R. sanguineus ( s.l. )…”
