“…The estimated prevalence of Q fever in Latvian dairy cows is close to the 8% herd level prevalence reported for Sweden [32] and considerably lower than the herd level prevalence reported in countries of western Europe (82% in The Netherlands [18], 79% in Denmark [16], 72% in Germany [33] or 70% in Spain [34]) or central Europe (40% in Poland [35]). Other countries of northern Europe have reported even lower levels of prevalence in dairy cattle herds -0% in Norway [36] and 0•24% in Finland [37] suggesting that in northern Europe C. burnetii infections of dairy cattle are significantly less common as opposed to western and central Europe.…”

The purpose of this study was to describe prevalence and spatial distribution of Coxiella burnetii infections in dairy cow sheds in Latvia and to investigate risk factors contributing to C. burnetii infections. Blood serum samples from abortion cases from 1010 sheds have been tested by ELISA for the presence of C. burnetii antibodies and bulk tank milk (BTM) samples from 252 sheds have been tested by real time polymerase chain reaction and ELISA for the presence of C. burnetii DNA and antibodies. Prevalence of C. burnetii antibody-positive sheds in cases of abortion was 13·4%. A total of 10·7% and 13·2% of dairy cow sheds tested positive for the presence of C. burnetii DNA and antibodies in BTM, respectively. Two distinct areas of clustering of test-positive dairy cattle sheds were identified by spatial scan statistics of abortion cases and randomly sampled BTM samples. Three factors were identified as significantly contributing to the risk of C. burnetii DNA presence in BTM - number of cattle in shed (>200 animals/shed) (OR 3·93), location of the shed within risk area in Northern Latvia (OR 8·29) and for the first time, purchasing cattle from abroad has been shown to significantly increase risk (OR 2·68) of C. burnetii infection in dairy cows in Latvia.

“…Therefore, it is not surprising that cattle were the primary source of the Q fever outbreaks in Poland, whereas in general, the small ruminants are considered to be the main source of infection for humans (Chmielewski and Tylewska-Wierzbanowska, 2013). The seroprevalence among cattle herds in this study was significantly lower than reported in the previous survey (Jodełko et al, 2015) when samples were tested by CFT (Siemens Healthcare, Germany). The cause of decrease of seroprevalence has not yet been determined, but we speculate that it may be related to differences in diagnostic method.…”

Summary. -Coxiella burnetii is the causative agent of Q fever. The cases of the disease are recorded in various species, including domestic animals. The aim of this investigation was to estimate the seroprevalence of C. burnetii in ruminants including cattle, sheep, goats, and horses. Totally, 2082 serum samples from 936 goats, 933 cattle, 89 sheep, and 124 horses, including various horse breeds, were tested by ELISA or complement fixation test. The examination revealed that Polish horses are seronegative while in the populations of cattle and small ruminants, seropositive animals are presented. The percentage of seropositive cattle, goats and sheep was 4.18, 6.30, and 13.48, respectively.

“…Also in Poland a serological monitoring programme for cattle and small ruminants has been implemented [9] since 2010. According to recently published data, herd-level seroprevalence in Polish cattle was estimated at 40.41%, which corresponds with European averages [10]. However, there is lack of information about current prevalence of C .…”

Q fever is a worldwide zoonotic disease reported in humans and many animal species including cattle. The aims of this study were to evaluate the prevalence of Coxiella (C.) burnetii shedding in Polish dairy cattle herds and to identify the pathogen’s genotypes and sequence types (STs) using multiple-locus variable number tandem repeat analysis (MLVA) and multispacer sequence typing (MST) methods. The presence of C. burnetii DNA was detected using a commercial real-time PCR kit, targeting the IS1111 element. Overall, 1,439 samples from 279 herds were tested including: 897 individual milk specimens, 101 bulk tank milk samples, 409 genital tract swabs and 32 placentas. Furthermore, 30 consumer milk samples, including 10 from vending machines and 77 dairy products were also analyzed. C. burnetii shedding was confirmed in 31.54% of tested cattle herds as well as in 69.16% of consumer milk and dairy products. Among real-time PCR–positive samples, 49 specimens obtained from 49 cattle herds and 8 samples of purchased dairy products were selected for genotyping. Overall, five previously known MLVA genotypes (I, J, BG, BE, and NM) and three new ones (proposed as PL1, PL2, and PL3) were identified. Two MST sequence types were recorded: ST16 and a novel sequence (ST61). The new genotypes and sequence types need further research particularly into their pathogenicity to humans.
