Abstract. This study was conducted from September 2011 to March 2014 to address the occurrence and genotypes of Coxiella burnetii using molecular methods in ticks collected from domestic animals in Ethiopia. Ticks were tested for C. burnetii by quantitative real-time polymerase chain reaction (qPCR) targeting two different genes followed by multispacer sequence typing (MST). An overall prevalence of 6.4% (54/842) of C. burnetii was recorded. C. burnetii was detected in 28.6% (14/49) of Amblyomma gemma, 25% (31/124) of Rhipicephalus pulchellus, 7.1% (1/14) of Hyalomma marginatum rufipes, 3.2% (2/62) of Am. variegatum, 3.1% (4/128) of Am. cohaerens, 1.6% (1/63) of Rh. praetextatus, and 0.6% (1/153) of Rhipicephalus (Boophilus) decoloratus. Significantly higher overall frequencies of C. burnetii DNA were observed in Am. gemma and Rh. pulchellus than in other tick species (Mantel-Haenszel [MH], P 0.0001). The overall frequency of C. burnetii was significantly higher (MH, P 0.0001) in ticks from southeastern districts (Arero, Moyale, and Yabelo) than that from other districts. This study demonstrated the presence of C. burnetii genotype MST 18 in ticks in southeastern districts and genotype MST 20 in ticks in central districts. This study highlights the importance of ticks in the epidemiology of C. burnetii in Ethiopia.

“…However, in ticks removed from the dogs, most of which belonged to the brown dog tick, C. burnetii DNA was not detected [29]. Similarly, although human Q fever infection related to the dogs had been previously described in Japan [11], later studies did not show the presence of C. burnetii in ticks removed from pet dogs in urban environments [30].…”

Molecular Evidence of Q Fever Agent Coxiella Burnetii in Ixodid Ticks Collected from Stray Dogs in Belgrade (Serbia)

Q fever is a zoonotic disease caused by Coxiella burnetii, a gram-negative coccobacillus, which has been detected in a wide range of animal species, mostly domestic ruminants, but also in wild mammals, pets, birds, reptiles, arthropods (especially ticks), as well as in humans. Although the exposure to domestic animals in rural areas is regarded as the most common cause of the disease in humans, recent studies have shown that the role of pets in the epidemiology of Q fever has been increasingly growing. Although the primary route of infection is inhalation, it is presumed that among animals the infection circulates through ticks and that they are responsible for heterospecifi c transmission, as well as spatial dispersion among vertebrates. The aim of this study was to determine the presence and prevalence of C. burnetii in ticks removed from stray dogs, as well as to examine the distribution of tick species parasitizing dogs on the territory of Belgrade city. A PCR protocol targeting IS1111 repetitive transposon-like region of C. burnetii was used for the detection of C. burnetii DNA in ticks and the results were confi rmed by sequence analysis. In total, 316 ticks were collected from 51 stray dogs - 40 females (78.43%) and 11 males (21.57%). Three species of ticks were identifi ed: Rhipicephalus s anguineus (72.15%), Ixodes ricinus (27.53%) and Dermacentor reticulatus (0.32%). Out of 316 examined ticks, C. burnetii DNA was detected only in the brown dog tick R. sanguineus, with a total prevalence of 10.53% (24/228) . The high prevalence of C. burnetii in R. sanguineus, which is primarily a dog tick, indicates the importance of dogs in the epidemiology of Q fever in the territory of Belgrade.

“…The main route of C. burnetii transmission to humans is inhalation of contaminated aerosols, but it may occur through the consumption of raw infected milk and dairy products (Khalili & Sakhaee, 2009;Andoh et al, 2013;Sykes, 2013). Dogs and cats might be infected by consumption of placenta or milk from infected ruminants, or by the aerosol route.…”

“…Dogs and cats might be infected by consumption of placenta or milk from infected ruminants, or by the aerosol route. Contact with infected wildlife reservoir such as rodents, rabbits and tick bites is considered to have a low potential for C. burnetii transmission (Angelakis & Raoult, 2010;Andoh et al, 2013;Sykes, 2013;Meredith et al, 2015). Q fever infection in animals is mainly subclinical, though some reproductive tract diseases including late abortions, stillbirth, infertility and metritis have been reported (Buhariwalla et al, 1996;Porter et al, 2011;Sykes, 2013).…”

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.
