“…There is no report of an urban Q fever outbreak in Japan. 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.

“…In present study, breed, type of housing, type of food and presence of clinical signs showed no significant differences between positive and negative cases. Based on the literature, high prevalence of C. burnetii has been reported in the urine of dogs and human infection has been directly linked to the pet dogs (Komiya et al, 2003;Tozer et al, 2014). Therefore, no clinical signs of positive cases might have a decisive role in human infections.…”

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.

“…Les chiens et les chats peuvent aussi être infectés par C. burnetii et être associés avec des infections humaines dans les régions rurales et urbaines . Ainsi, au Japon, les chats sont considérés comme l'un des plus importants réservoirs de C. burnetii (Komiya et al 2003). Il faudrait des investigations plus poussées pour vérifier la transmission inter-espèce et exclure la circulation indépen-dante de différentes souches spécifiques d'espèce comme cela a déjà été démontré chez les ruminants domestiques (Roest et al 2013b).…”

Résumé : La fièvre Q est une zoonose de répartition mondiale excepté la Nouvelle-Zélande. Elle est due à une bactérie intracellulaire : Coxiella burnetii. Cette infection passe souvent inaperçue car la manifestation principale de la forme aiguë de la maladie est un syndrome pseudogrippal spontanément résolutif. C'est l'épidémie qui a eu lieu aux Pays-Bas qui a attiré l'attention sur cette maladie qui était moins étudiée auparavant. Cette synthèse résume la description de la bactérie (taxonomie, cycle intracellulaire et génomique) mais également la maladie (description, diagnostic, pathogénie et épidémiologie). Enfin, la vaccination de l'humain et des animaux est également analysée. Mots-clés : Coxiella burnetii, fièvre Q, épidémiologie, description, génomique.Abstract: Q fever is a zoonosis of worldwide distribution with the exception of New Zealand. It is caused by an intracellular bacterium, Coxiella burnetii. The disease often goes underdiagnosed because the main manifestation of its acute form is a general self-limiting flu-like syndrome. The Dutch epidemics renewed attention to this disease, which was less considered before. This review summarizes the description of C. burnetii (taxonomy, intracellular cycle, and genome) and Q fever disease (description, diagnosis, epidemiology, and pathogenesis). Finally, vaccination in humans and animals is also considered.
