Isolation of Coxiella burnetii from the Vagina of Feline Clients at Veterinary Clinics.

The bacterium Coxiella burnetii has been detected in the fetal membranes, birth fluids and vaginal mucus, as well as in the milk and other excretions of several domestic mammals. The finding of C. burnetii in association with abortion, parturition and in the postpartum period has led to the hypothesis that C. burnetii causes a range of reproductive diseases. This review critically evaluates the scientific basis for this hypothesis in domestic mammals.The review demonstrates a solid evidence for the association between C. burnetii infection and sporadic cases of abortion, premature delivery, stillbirth and weak offspring in cattle, sheep and goats. C. burnetii induced in-herd epidemics of this complete expression of reproductive failure have been reported for sheep and goats, but not for cattle. The single entities occur only as part of the complex and not as single events such as generally increased stillbirth rate. Studies show that C. burnetii initially infects the placenta and that subsequent spread to the fetus may occur either haematogenous or by the amniotic-oral route. The consequences for the equine, porcine, canine and feline conceptus remains to the elucidated but that infection of the conceptus may occur is documented for most species. There is no solid evidence to support a hypothesis of C. burnetii causing disorders such as subfertility, endometritis/metritis, or retained fetal membranes in any kind of domestic animal species.There is a strong need to validate non-pathology based methods such as polymerase chain reaction for their use in diagnostic and research in relation to establishing C. burnetii as the cause of abortion and to adapt an appropriate study design and include adequate control animals when linking epidemiological findings to C. burnetii or when evaluating effects of vaccination in production herds.

“…However, seroepidemiology of companion animals shows the presence of C. burnetii in urban residential areas of Japan; 60 of 589 (10%) and 95 of 632 (15%) dogs [6,16] and 16 of 100 (16%), 23 of 150 (15%) and 44 of 310 (14%) cats [8,14,16] were reported as seropositive. Also, the DNA of the bacteria was detected in 2 dogs [9] and 4 of 310 (0.3%) companion cats [8], and the bacteria was isolated from 9 of 29 (31%) companion cats [15].…”

ABSTRACT. For a survey of Coxiella burnetii, the Q fever agent, ticks infesting companion dogs were collected in Aomori, Tochigi, Gifu and Okinawa Prefectures, Japan. A total of 261 ticks were collected, and their species were identified morphologically. Five tick species were identified: Ixodes ovatus, Haemaphysalis concinna, H. flava, H. longicornis and Rhipicephalus sanguineus. Total DNA was extracted from them individually followed by real-time PCR to detect a C. burnetii-specific gene. The results of real-time PCR were all negative, which might suggest a low risk of C. burnetii infection via these ticks and their hosts in urban residential areas in Japan.

“…Prevalence data are variable and likely depend on region, study population, and laboratory technique. 344 There are fewer studies in dogs. 339 A PCR -based study of uterine biopsies identifi ed C. burnetii DNA in 8.5% of cats in Colorado, USA, 343 while a study of cat serum in Korea and Japan detected C. burnetii DNA in 1.4% of samples.…”
