“…To date A. ovis has never been reported infecting small ruminants in Brazil. Despite the high host specificity of Rhipicephalus microplus to cattle (Dantas-Torres et al, 2009;Ma et al, 2016), this tick species may be found parasitizing small ruminants (Brito et al, 2005;Da Silva et al, 2018).…”

Although anemia has been historically linked to Haemonchus contortus infection, other infectious agents, such as hemotropic mycoplasmas and tick-borne disease pathogens, may also lead to anemic crisis in sheep. This study has aimed to investigate infections related to anemia in a sheep herd from Bandeirantes City, Paraná State, southern Brazil. Seven out of forty-two (16.6%; 95% CI: 8.32–30.6%) sheep were positive for hemoplasmas by a PCR targeting the 16S rRNA gene and all tested negative for A. marginale/A. ovis and Babesia/Theileria spp. by PCR based on msp4 and 18S rRNA genes, respectively. Two (4.7%; 95% CI: 1.32–15.79%) animals were infested with Rhipicephalus microplus ticks. Fecal egg counting was performed in 38 sheep and 24 (63.15%; 95% CI: 47.2–76.6%) presented > 500 eggs per gram. Phylogenetic analysis of partial sequences of the detected hemotropic Mycoplasma sp. 16S and 23S rRNA genes confirmed that the animals were infected with Mycoplasma ovis. Polymorphism analysis of partial 16S rRNA sequences showed three different genotypes of M. ovis infecting sheep assessed in the present study. Mycoplasma ovis and gastrointestinal nematodes occurs in sheep from the northern region of Paraná State.

“…China has a relatively high tick species diversity, and over 120 species (about 13% of world species) have been described across its geography and infesting different hosts (Bush & Robbins, ; Chao, Hsieh, & Shih, ; Chao, Lu, Lin, & Shih, ; Z. Chen et al, ; Deng & Jiang, ; Duan, ; T. Guo, Sun, Xu, & Durden, ; Y. Guo, Sun, & Xu, ; W. Li, Sun, Zhang, & Xu, ; Wen & Chen, ; Yin & Luo, ; X. Yu, Ye, & Gong, ). Owing to the medical and economic importance of ticks, increasing studies have paid more attention to tick biology (Z. Chen, Yu, Yang, Zheng, & Liu, ; J. Li et al, ; J. Liu, Liu, Zhang, Yang, & Gao, ; Ma et al, ), tick ecology (T. Wang et al, ; Zheng, Yu, Zhou, Yang, & Liu, ), and tick‐borne disease (Chu et al, ; Fang et al, ; Wu, Na, Wei, Zhu, & Peng, ; Z. Yu et al, ), especially reports of the new emergence of tick‐borne pathogens in recent years (H. Li et al, ; Y. Z. Zhang & Xu, ).…”

Ticks are obligate blood‐sucking ectoparasites, which not only directly damage through bites but also transmit many pathogens. China has a high diversity of tick species, 125 species have been reported, including 111 hard tick and 14 soft tick species. Many of the ticks are important vectors of pathogens, resulting in zoonoses. The dynamics of ticks are affected by both the host and habitat environment. However, systematic studies on the geographical distribution, host diversity, and specificity of ticks are limited in China. To achieve this goal, the relevant available data were summarized and analyzed in this study. Ticks are distributed in all parts of China and Xinjiang has the most records of ticks. The distribution of ticks in adjacent areas is similar, indicating that the habitat environment affects their distribution. Most ticks are widely distributed, whereas some species are endemic to their distributed regions. Ticks are parasitic on mammals, birds, and reptiles, of which mammals are the main host species. Overall, most ticks parasitize different hosts, only a few ticks have strict host specificity, such as ticks that are specifically parasitic on reptiles and bats. In addition, environmental changes and control efforts also influence the dynamics of ticks. These results can better reveal tick biological traits and are valuable for tick control.

First report of Anaplasma marginale infection in goats, Brazil

et al. 2018

Anaplasma marginale, the causative agent of bovine anaplasmosis, is a tick-borne bacterium that causes significant economic losses for cattle industries and is increasingly being detected in other animal species. Rhipicephalus microplus is the main vector of this bacterium and may be found parasitizing small ruminants. In northeastern Brazil, multispecies grazing is a common family subsistence practice on smallholder farms possibly facilitating interspecies transmission of pathogens. Considering that A. marginale infection has been previously molecularly described in sheep, this study has aimed to estimate the prevalence of A. marginale and factors associated with the infection in goats from northeastern Brazil. A total of 403 goat blood samples were included in the study. An epidemiological questionnaire was applied to each farm owner addressing age, gender, presence of ticks and multispecies grazing. All samples were screened for A. marginale- and A. ovis-infection using primers targeting the Anaplasma spp. msp4 gene. The identity of A. marginale in the blood was confirmed by PCR amplification of msp5 followed by sequencing. Anaplasma spp. were differentiated by sequencing of the repeat region of the msp1α gene. For the statistical analysis the Chi-square or the Fisher’s exact test was used to verify association of the individual factors (age, gender, presence of ticks, and multispecies grazing) with Anaplasma spp. infection. We report the first molecular detection of A. marginale in goats from northeastern Brazil, based on msp1α, msp4 and msp5 gene sequencing analysis. Sequencing of the detected A. marginale msp1α gene revealed the F repeat. Amblyomma parvum and R. microplus were found feeding on animals.
