“…Contact with ticks may explain the high seropositivity of the group [ 34 ]. For most researchers, the potential for transmission from dogs to humans is low [ 35 ]. In addition to cattle, dogs and cats that are in close contact with humans are important potential reservoirs of C. burnetii during urban outbreaks of Q fever.…”

Background: Although the Coxiella burnetii infection has been investigated in dogs, its role in human transmission remains to be fully established, particularly in close and daily human–dog contact settings, such as in Police K-9 Units. Methods: Accordingly, this study aimed to assess anti-C. burnetii antibodies in clinically healthy police officers by an in-house indirect immunofluorescence assay (IFA), and working dogs by a commercial IFA Kit, from the State Special Operations Battalion, Paraná, Southern Brazil. Results: Overall, 1/18 (5.5%) police officers and 9/30 (30.0%; CI 95% 16.66–47.88) dogs tested seropositive to anti-C. burnetii IgG antibodies. Conclusions: To date, this is the highest prevalence of Q fever seropositivity among military dogs worldwide. Despite the low sampling rate, a statistically significant association was found between seropositivity and female dogs (p = 0.0492). Further studies with larger sample sizes should be conducted to establish the prevalence of Q Fever in other Brazilian K-9 Units. In summary, this study is the first to conduct a concomitant serosurvey of police officers and working dogs, and its findings should be considered a warning for cross-exposure and transmission of Coxiella burnetii among Police K-9 Units in Brazil and worldwide.

“…To reduce the risk of infection in domestic ruminants, preventive farm management measures must be effected. Identification and slaughter of herds and the control of animal movements can influence transmission to humans (Souza et al, 2022). In Nigeria, some of the factors associated with infection with C. burnetiii n ruminant herds include sources of water for the livestock, the watering system and method of handling of aborted foetuses.…”

Q fever, a neglected zoonotic disease in Nigeria- a review

Q fever still remains a neglected zoonotic disease in several developing countries including Nigeria. The aetiologic agent Coxiella burnetii is a resistant intracellular bacterium which causes long-lasting infections in both human and animals. The infection is usually asymptomatic in animals but can affect reproduction such as abortion in animal herds resulting in the disease mostly remaining undiagnosed leading to economic consequences. In humans, the infection can lead to severe endocarditis and vascular infection in chronic cases. Data is still limited on the molecular epidemiology such as genomic studies and evolution of this pathogen especially in humans and this has to be explored. Awareness programs on the public health importance of this disease, it’s preventive and control measures in Nigeria would help in Q fever management.

Coxiella burnetii Infection in Livestock, Pets, Wildlife, and Ticks in Latin America and the Caribbean: a Comprehensive Review of the Literature

Purpose of the Review Q fever , a bacterial zoonosis caused by Coxiella burnetii, is reported very heterogeneously in humans in Latin America. The objective of this study was to review the data on Coxiella burnetii Infection in animals in Latin America and the Caribbean. Recent Findings A comprehensive literature review was carried out in the 47 countries and territories of Latin America on various search engines and grouped into four groups: livestock, pets, wildlife, and ticks. Summary Thus, 113 studies were selected between 1950 and 2022. Among the 47 countries, only 25 (53%) had at least one publication related to C. burnetii infection in animals. The most productive country was Brazil (N = 51), followed by French Guiana (N = 21), and Colombia (N = 16). Studies in livestock from 20 countries have shown widely varying country-to-country rates of seroprevalence, ranging from 0 to 67%. Some studies from seven countries, especially French Guiana and Brazil, found antibodies and sometimes positive PCR in dogs and cats, generally in the context of investigations around human clustered cases. Knowledge remained fragmented about infection in wildlife from only five countries (Chile, Colombia, Brazil, French Guiana, and Uruguay). C. burnetii infection was identified by PCR in Chiroptera (7 species), Rodentia (6 species), Suina (2 species), Xenartha (1 species), Cingulata (1 species), and Perissodactyla (1 species). Studies on Coxiella sp. in ticks have been performed in 11 countries, mostly in Brazil, and mainly found Coxiella-like endosymbionts. Thus, data on C. burnetii infection in animals are sparse and incomplete in Latin America and the Caribbean, and more research is warranted.
