Varroa destructor, a parasitic mite of the Western honey bee Apis mellifera L., is a serious threat to colonies and beekeeping worldwide. Population genetics of the mite has provided information of two mitochondrial haplotypes infecting honey bee colonies, named K (Korea) and J (Japan). In the American continent, the K haplotype was most frequently found. The aim of this research was to study the genetic diversity of V. destructor populations from the major beekeeping region of Argentina, previously unexplored. Phoretic mites were collected from managed A. mellifera colonies in ten localities, and four mtDNA regions (cox1, nad4, nad4L, and nad5) were analyzed. Based on cox1 sequence, the exclusive presence of K haplotype was detected. Two sub-haplotypes (KArg-N1 and KArg-N2) were identified from a variation in nad4 sequence. The frequency of these sub-haplotypes significantly correlates with the geographic latitude. The occurrence of site heteroplasmy was also evidenced for this gene. The nad4 mtDNA marker appears to be a sensitive marker to detect genetic variability in mite populations. The site heteroplasmy emerges as a phenomenon that could be relatively frequent in V. destructor.

“…The tick Haemaphysalis flava Neumann is an important ectoparasite, which not only damages its hosts directly but also serves as a vector for various infectious pathogens in China (Cheng et al 2013, Lu et al 2013, Li et al 2017. Recent studies have also reported Haemaphysalis longicornis Neumann and Haemaphysalis hystricis Supino in China (Lu et al 2017, Wang et al 2018, Zhang et al 2018, Li et al 2019b, Yang et al 2019, Zheng et al 2019. Haemaphysalis bispinosa Neumann has been believed to occur in China, especially in the southern part.…”

A three-year-old male South China tiger died in the tiger enclosure of the China Tiger Park in the Meihua Mountains on December 2018 after being bitten by a tick. This tiger presented clinical symptoms like whole-body severe jaundice, hepatosplenomegaly, kidney, and lymph node hemorrhages. The Colpodella sp.-specific 18S rRNA gene was detected using nested PCR. Interestingly, the DNA isolated from the blood of the tiger was found to be 100% similar to that of the tick by NCBI BLAST analysis. However, the DNA fragments isolated from the tiger's blood were 90.1% similar to the Colpodella sp. strain human erythrocyte parasite (HEP, MH208621) and 90.4% similar to the Colpodella sp. strain Heilongjiang (HLJ, KT364261). To investigate the species of ticks and ticks-carried Colpodella parasites in this region, the species of ticks obtained from the grasses outside the tiger enclosure and the species of Colpodella carried by ticks were identified. The DNA from ticks as well as that from the tick-borne Colpodella sp. were amplified from each tick using PCR followed by amplicon sequencing. In total 402 adult ticks samples were collected, among which 22 were positive for Colpodella sp. (5.5%), and the species were further determined by morphology, DNA sequencing and phylogenetic analyses. Interestingly, one Colpodella sp. was found to have 94.2% sequence similarities to the Colpodella sp. strain HEP (MH208621). This strain was previously reported to infect a woman in Yunnan, China. In addition, three Colpodella sp. showed 87-91% sequence similarities to the Colpodella sp. strain HLJ (KT364261), which was previously reported to infect human in Heilongjiang, China. This study disclosed the possibility of zoonotic transmission of Colpodella sp. by ticks in China. Finally, it provides a basis for urgently determining and monitoring the repertoire of ticks-borne piroplasmid pathogens, with the ultimate aim of strategic control.
