Blood samples from 426 healthy and sick cats in the UK were tested in a PCR assay for
‘Candidatus
Mycoplasma haemominutum’ and
Mycoplasma haemofelis
(basonym
Haemobartonella felis
). Seventy‐two of the cats (16·9 per cent) were positive for
‘Candidatus
M haemominutum’ alone, six (1·4 per cent) were positive for
M haemofelis
alone and one (0·2 per cent) was positive for both. Logistic regression analysis indicated that older male cats were significantly more likely to be infected with
‘Candidatus
M haemominutum’, but there was no significant association between it and any of the haematological variables measured.
M haemofelis
infection was uncommon in the anaemic cats sampled, and there were too few positive cases for multivariable analysis to be performed for
M haemofelis
‐positive status.
