“…The male preponderance in our study conforms with other Australian [ 18 ], and international studies [ 19 ]. Demographic profiles including education and usual place of residence based on the IRSAD decile, indicate Australian livestock farmers' modest overall socioeconomic status and possibly highlights the cost of vaccination as a barrier [ 18 ].…”

Q fever prevention and vaccination: Australian livestock farmers' knowledge and attitudes to inform a One Health approach

Background Livestock farmers are at risk of Q fever, a zoonotic disease transmitted to humans from animals such as cattle, sheep and goats. Australia bears substantial Q fever burden, particularly among farmers. A One Health approach engages cross-sectoral collaboration among animal, human and environmental health and is the preferred framework for Q fever prevention. Methods Cattle, sheep and goat farmers were invited to participate in an online survey in 2019 to gauge perceptions about Q fever and its prevention. Participants were recruited via membership newsletters and social media. Descriptive analyses and logistic regressions were performed. Results A total of 351 farmers completed the survey. Most respondents (80%) had been farming for ≥20 years, with sheep and beef cattle their primary stock. 71% reported knowledge of Q fever, and 85% identified transmission through contaminated dust inhalation was highly likely. The majority of respondents (97%) were aware of Q fever vaccine, and 95% agreed it was effective in preventing disease, yet 42% remained unvaccinated. Reported barriers to vaccination included poor access to a trained doctor and time and cost related to vaccination. Most farmers (≥91%) believed that subsidized vaccination and improved awareness would promote higher uptake. Conclusion While Q fever knowledge among respondents was good, their practices related to airborne transmission prevention were poor. Livestock farmers would benefit from adherence to dust and aerosol transmission prevention practices. One Health partnership between government and industry is needed to promote Q fever awareness and address low vaccination rates among livestock farmers by funding vaccination programs.

Coxiella burnetii is a highly infectious zoonotic pathogen infecting wide range of mammals, including humans. In the present study, a total of 711 blood samples from bovines [cattle (n = 543) and buffaloes (n = 168)] from eight farms at different geographical locations in India were screened for C. burnetii targeting the IS1111 and the com1 genes. The anti-C. burnetii antibodies in serum samples were detected using indirect-ELISA kits. Also, a total of 21 parameters pertaining to animal health and farm management were identified to assess their role as possible risk factors for coxiellosis among the targeted farms. The apparent prevalence (positive for PCR and/or ELISA) for coxiellosis was reported to be 24.5% in cattle and 8.9% in buffaloes. In cattle, the detection rate of C. burnetii employing the IS1111 gene (8.5%) was found to be significantly higher (p<0.05) as compared to the com1 (6.5%) gene. The seropositivity by ELISA was higher among cattle (17.7%) than in buffaloes (8.3%). Further, on univariable analysis of risk factors, species (cattle) (

“…Furthermore, Sun et al (2016) reported that the seroprevalence rate of anti-C. burnetii phase II IgG antibodies was higher 43.21% (105 out of 243) among cattle farmers and farm residents with a history of consumption of raw cow milk in China versus a seroprevalence rate of 20.17% (24 out of 119) among those who hadn't. In addition, Park et al (2018) declared that the seroprevalence rate of anti-C. burnetii phase II IgG antibodies was higher 13.46% (7 out of 52) among dairy cattle farmers who had the habit of consumption of raw cow milk in Korea versus a seroprevalence rate of 10.88% (127 out of 1,167) among those who didn't ever consume raw cow milk. As well, Mostafavi et al (2019) showed that the Iranian humans who consumed unpasteurized milk and dairy products had a higher seroprevalence rate of anti-C. burnetii phase II IgG antibodies 37.43% (67 out of 179) in comparison with a seroprevalence rate of 28.18% (51 out of 181) among those who didn't.…”

Q fever is a major anthropozoonotic disease infecting animals and man all over the world except in the Antarctic and New Zealand. This study aimed to highlight the public health significance of Q fever among dairy cattle and the potential role of raw milk products in transmitting the infection to humans in Menoufia governorate. A total of 60 raw milk samples were collected from 60 apparently healthy Baladi dairy cows of different ages from 3 localities in Menoufia governorate (20 from Shebein El-Kom, 20 from Tala and 20 from Menouf) and examined for presence of C. burnetii DNA by PCR. Results revealed that 25% (15/60) of milk samples had C. burnetii DNA. No significant association was revealed between PCR positivity and the cattle age or selected localities. Moreover, the current study involved estimation of seroprevalence of anti-C. burnetii phase II IgG antibodies by ELISA test among 184 attendants of Shebein El Kom fever and chest hospitals in Menoufia governorate in relation to the habit of consumption of unpasteurized milk products. 41.85% (77/184) of the examined individuals were positive for phase II IgG antibodies. A highly significant association was found between increased seroprevalence and the pattern of consumption of unpasteurized milk products per week since the patients with the habit of usual consumption (5-7 days/week) had the highest seroprevalence rate 56.10% (23/41) versus 47.14% (33/70) and 28.77% (21/73) among those with moderate (2-4 days/week) and rare (0-1 days/week) patterns of consumption, respectively. In conclusion, presence of C. burnetii DNA in milk of cattle and C. burnetii phase II IgG in contact human being could confirm the role of food from animal origin in transmission of Q fever to man.
