“…C. burnetii has been detected in different biological fluids like urine, feces, milk, and placenta of infected animals; tropism of this microbial agent by cells of the reproductive system has been evidenced, thus affecting consumers of unpasteurized milk 43 . Corroborating these results, C. burnetii has been previously detected in bovine milk from Colombia 44 . In addition, serological evidence of exposure to this zoonotic agent in people engaged in livestock activities has also been reported in the departments of Córdoba and Sucre, in towns like La Ceja, Envigado and Caracoli, also being found in other Antioquia regions 45 .…”

Bacteria belonging to Anaplasma, Ehrlichia, Rickettsia and Coxiella genera are considered emerging pathogens and livestock is one of the contexts where the transmission of these microorganisms can occur. The goal of this study was to determine serological evidence for the exposure to these bacteria in cattle and humans with occupational exposure to livestock in the subregions North and Magdalena Medio, Antioquia, Colombia, and to explore related factors. A cross-sectional study was conducted in 48 livestock farms distributed in six municipalities from both subregions: Belmira, Entrerríos and San Pedro de los Milagros (North), and Puerto Berrío, Puerto Nare and Puerto Triunfo (Magdalena Medio). Blood samples from 332 people and 384 bovines were evaluated by serology (IgM and IgG) screening for bacteria from the Anaplasma, Ehrlichia, Rickettsia, and Coxiella genera. Seropositivity in humans from both regions was 42.4% (95%CI: 31.2-55.1) for Anaplasma, 74.2% (95%CI: 66.0-84.4) for Ehrlichia, 72.5% (95%CI: 62.1-82.0) for Rickettsia, and 60.7% (95%CI: 59.7-69.1) for Coxiella burnetii. In cattle, seropositivity was 31.6% (95%CI: 19.9-44.2), 66.8% (95%CI: 55.2-78.1), 64.6% (95%CI: 53.8-74.5), and 61.6% (95%CI: 51.9-69.2), respectively. History of biting by ticks, milking, vaccination, having dogs and hens in the residence, as well as the consumption of raw milk derivatives were some factors associated with the infection by the bacteria studied. The results suggest a previous and recent exposure to these zoonotic bacteria genera in people with occupational exposure to livestock, as well as in cattle in the two studied subregions.

“…Possible sources of heterogeneity were investigated through the analysis of moderators. The evaluated moderators included: i) geographic region: Europe vs non-Europe; ii) average herd size; iii) local legislation for Q fever: mandatory notification vs non-mandatory notification [ [29] , [30] , [31] , [32] , [33] , [34] , [35] , [36] , [37] ], and iv) gross national income (GNI) per capita classification from the year the study was conducted, based on the Atlas method [ 38 ]. A subgroup analysis was performed for the categorical moderators.…”

Molecular prevalence of Coxiella burnetii in bulk-tank milk from bovine dairy herds: Systematic review and meta-analysis

et al. 2021

Coxiella burnetii is an obligate intracellular zoonotic bacterium that causes Q fever. Ruminants, including cattle, are broadly known to be reservoirs for this bacterium. Since 2006, many research groups have evaluated the herd-level prevalence of C. burnetii in cattle by molecular techniques on composite milk samples. This study explored the global C. burnetii herd-level prevalence from studies done on bovine bulk-tank milk (BTM) samples using PCR-based analysis. Also, moderators were investigated to identify sources of heterogeneity. Databases (CAB Abstracts, Medline via Ovid, PubMed, Web of Science and Google Scholar) were searched for index articles on C. burnetii prevalence in BTM samples by PCR published between January-1973 and November-2018. Numerous studies (1054) were initially identified, from which seventeen original publications were included in the meta-analysis based on the pre-defined selection criteria. These studies comprised 4031 BTM samples from twelve countries. A random-effects model was used because of considerable heterogeneity ( I 2 = 98%) to estimate the herd-level prevalence of C. burnetii as 37.0%(CI 95% 25.2–49.5%). The average herd size appeared to account for a high level of the heterogeneity. No other moderators (geographic location, gross national income or notification criteria for Q fever) seemed to be determinant. This systematic evaluation demonstrated a high molecular prevalence of C. burnetii in BTM samples both in European and non-European countries, evidencing a widespread herd-level circulation of this agent in bovine dairy farms around the world. Meta-regression showed herd size as the most relevant moderator with the odds of a BTM sample testing positive doubling with every unit increase.

“…In Turkey, C. burnetii was detected in milk by immunomagnetic separation-PCR [ 50 ]. Near Paraguay, in Montería in Colombia, C. burnetii was detected by PCR in milk from bulk tanks on 5/11 dairy farms (45%) [ 51 ]. In a study carried out in dairy sheep flocks in the Basque Country, Spain, the elimination of C. burnetii through milk was observed in several flocks 10 years after its first detection [ 52 ].…”
