“…The present seroprevalence was higher than that reported in new states of Federal Republic of Germany (3%, n=1620) (Kramer, 1991), North Italy (0.87%, n=802) (Baldelli et al,1992), New Zealand (0%, n=12556) (Hilbink et al, 1993) and Canada (0%, n=447) (Marrie et al, 1985), but lower than reported seropositivity in Australia (11.4%, n=201) (Cooper et al, 2011), Southern Croatia (12%, n=51) (Punda-Polić et al, 1994), Japan (15%, n=632) (Htwe et al, 1992), Nigeria (29%, n=786) (Addo & Bale, 1981), Switzerland (31%, n=388) (Metzler et al, 1983) and California (66%, n=316) (Willeberg et al, 1980). Although there is no information about Q fever in dogs population in Iran, Asadi et al (2012) reported 19.5% and 27.2% seroprevalence of C. burnetii in sheep and goats respectively (Asadi et al, 2012).…”

Coxiella burnetii is an important zoonosis at a global scale. The epidemiological role of dogs in transmission of Q fever has recently been demonstrated, but there is still a dearth of information on the subject. The aim of present study was to evaluate the occurrence and seroprevalence of Coxiella burnetii infection among companion dogs population in Fars province, South Iran. Blood samples were collected from 181 asymptomatic dogs, mostly referred to Veterinary Hospital of Shiraz University for regular vaccination. The IgG antibody detection against C. burnetii was made by indirect Enzyme-linked Immunosorbent Assay (ELISA), employing C. burnetii phase I and II antigens. A logistic regression model was developed to analyse multiple risk factors associated with seropositivity. Specific antibodies against C. burnetii were detected in 14 (7.7%) cases, 12 with S/P% of 20-50% and 2 with S/P% greater than 80%. Prevalence was significantly higher in adult dogs above 5 years (18.18 %; 2 out of 11) compared with dogs between 1 and 5 years (7.86 %; 7 out of 89) and less than 1 year (6.17%; 5 out of 81) (P=0.043). Prevalence was also higher in male dogs (11.21 %; 12 out of 107) than in female (2.7 %; 2 out of 74) (P=0.035). Breed, type of housing, type of food and exposure to other farm animals showed no significant differences between positive and negative cases (P>0.05). The results of this study showed the presence of C. burnetii infection among the companion dogs population in Iran, which could be a public health concern for humans. In areas like Iran, where human cases of Q fever are not common or remain unreported, the public health implications of Q fever seroprevalence in dogs are quite significant.

“…Serological studies testing for the presence of C. burnetii in cattle have found prevalence rates around the world varying from 3.4% to 84% (Adesiyun et al 1984;Behymer et al 1985;Marrie et al 1985;Houwers and Richardus 1987;McQuiston et al 2002). However, studies on the presence of C. burnetii in bovines in Turkey remain somewhat limited (Seyitoglu et al 2006;Kirkan et al 2008).…”

This study was aimed at detection of Coxiella burnetii in bovine foetuses using polymerase chain reaction (PCR) and immunohistochemistry (IHC) and at an estimation of its frequency in Eastern Turkey. Stamp, Giemsa, and Gimenez stains were used in addition to PCR and IHC to determine the presence of C. burnetii in samples from 70 bovine foetuses. While the staining methods did not detect the agent by direct visualisation of C. burnetii on smears, PCR and IHC identified its presence in two of the foetuses. The distribution of antigens in these two foetuses was, in decreasing order of concentration, in the spleen, the thymus, the lungs, the liver, and the kidneys. We conclude that C. burnetii diagnosis in bovine foetuses can be reliably performed using PCR and IHC. In addition, the frequency of 1.42% of C. burnetii positivity in bovine foetuses reported here was the first time that the presence of this agent was determined in Eastern Turkey.

“…In maritime Canada, exposure to parturient cats and newborn kittens has been identified as a significant risk factor for Q fever 16 , with seroprevalence of C. burnetii infection in cats in these regions varying from 6.2 to 32% [17][18][19] . In other countries (such as South Africa, Japan and the USA), seroprevalence has ranged from 1.9 to 42% [20][21][22][23] .…”
