“…Q fever is a widespread zoonosis with pandemic potential caused by the intracellular bacterial pathogen Coxiella burnetii (C. burnetii) [1]. In some regions of the world, especially in islands such as American Samoa and Tahiti, the bacteria have not yet been detected, either because of its absence or its sporadic presence [1][2][3]. The estimates for C. burnetii antibody-positive humans in Europe varies between geographical regions and population groups, ranging from 2.4% in the Netherlands (2006)(2007) [4] and 5.35% in France (1995) [5] to 38% in Bulgaria (1995) [6].…”

Coxiella burnetii Antibody Prevalence and Risk Factors of Infection in the Human Population of Estonia

Q fever is an emerging health problem in both humans and animals. To estimate the prevalence of Coxiella burnetii (C. burnetii) antibodies in the Estonian population, we analyzed plasma samples from 1000 individuals representing the general population and 556 individual serum samples from five population groups potentially at a higher risk (veterinary professionals, dairy cattle, beef cattle, and small ruminant stockbreeders and hunters). Additionally, 118 dairy cow bulk tank milk samples were analyzed to establish the infection status of the dairy cattle herds and the participating dairy cattle keepers. Questionnaires were used to find the potential risk factors of exposure. The effects of different variables were evaluated using binary logistic regression analysis and mixed-effects logistic analysis. The prevalence in veterinary professionals (9.62%; p = 0.003) and dairy cattle farmers (7.73%; p = 0.047) was significantly higher than in the general population (3.9%). Contact with production animals in veterinary practice and being a dairy stockbreeder in C. burnetii positive farms were risk factors for testing C. burnetii seropositive (p = 0.038 and p = 0.019, respectively). Results suggest that C. burnetii is present in Estonia and the increased risk of infection in humans is associated with farm animal contact.Microorganisms 2019, 7, 629 2 of 12 estimates should be compared with caution as different approaches to determine seropositivity for Coxiella burnetii infection have been used in these studies. In most studies, indirect immunofluorescent assay (IFA) [2,3,7,11] or enzyme-linked immunosorbent assay (ELISA) [4,13] has been used, and less frequently the complement fixation test (CFT) [13]. The IFA has been shown to be the most sensitive and specific test for C. burnetii antibody detection, but since IFA testing is more laborious, combining ELISA as a primary screening test and IFA as a confirmatory test has been suggested for large-scale population studies [14].Domestic ruminants are considered one of the main infection sources for humans [13,[15][16][17][18][19][20]. The infection transmits to humans mainly through the inhalation of aerosols containing C. burnetii [13,15,19,21] or via direct contact with infected animals [22,23]. In lactating animals, the bacterium is excreted in the milk [24][25][26], and consuming unpasteurized goat's milk, cow's milk, or raw milk products is a risk factor for acquiring the infection [18,23,27]. Coxiella burnetii produces small spore-like forms [28] that enable the pathogen to survive in the environment for long periods of time [29,30]. Some environmental and meteorological conditions increase the risk of infection, such as higher wind speeds, soil, and landscapes being more sensitive to wind erosion and low rainfall [15,21,31]. A number of animal species, including pets [32][33][34][35], horses [36,37], birds [38], wildlife, and arthropods (mainly ticks) [39][40][41][42], might also play a role in spreading C. burnetii.The main risk factors for human infection are dire...

“…En 1955, Kaplan et Bertagna ont rapporté l'existence de la fièvre Q dans 51 pays des 5 continents, principalement chez les bovins, moutons, chèvres, et les humains (Kaplan et Bertagna 1955). Actuellement, C. burnetii a une distribution mondiale, excepté la Nouvelle-Zélande (Maurin et Raoult 1999) et probablement la Polynésie française (Musso et al 2014).…”

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.

Les bartonelloses et les rickettsioses sont des infections à transmission vectorielle souvent graveschez l'homme, mais asymptomatiques chez les animaux. Afin d'identifier de potentiels réservoirs et/ou vecteurs d'infections dues à Bartonella spp. et à Rickettsia spp. en Nouvelle-Calédonie, nous avons effectué des prélèvements de sang sur : 64 chiens, 8 chats, 30 bovins, 25 chevaux et 29 cerfs rusa (Rusa timorensis). Trois cent vingt neuf parasites externes hématophages (tiques, puces, mouches piqueuses) ont été collectés sur ces mêmes animaux. Quatre souches de Bartonella henselae ont été isolées chez les chats (50 %) et six de B. chomelii chez les bovins (20%). Bartonella aff. schoenbuchensis a été détectée chez 31% des cerfs ; Rickettsia felis chez 81% des 21 puces récoltées sur les chiens et B. clarridgeiae dans 1% des puces. Nos études confirment que les infections à bartonelles et rickettsies pourraient devenir une préoccupation croissante de santé publique en Océanie et montrent l'intérêt des nouveaux outils de diagnostic moléculaire pour la compréhension de ces maladies.
