Parasites & Vectors volume 17, Article number: 249 (2024)
Abstract
Background
Multiple species of the genera Cytauxzoon and Hepatozoon can infect wild felines, but the diversity of these and other apicomplexan parasites in Eurasian lynx is scarcely known. The aim of this study was to detect Cytauxzoon and Hepatozoon species with molecular methods in Eurasian lynxes and their ticks in northwestern China.
Methods
DNA was extracted from the heart, liver, spleen, lung, and kidney samples of three Eurasian lynxes as well as from their five ixodid ticks. These DNA samples were screened with polymerase chain reactions (PCRs) for Cytauxzoon with the partial cytochrome b gene (CytB), cytochrome c oxidase subunit I gene (COI), and small subunit ribosomal RNA gene (18S rRNA), and Hepatozoon with three different fragments of small subunit ribosomal RNA gene (18S rRNA). PCR products were sequenced, aligned, and phylogenetically analyzed.
Results
One adult female of Eurasian lynx (#1, adult female) was co-infected with Cytauxzoon manul and Hepatozoon felis genotype I, while an adult male lynx (#2) was infected with C. manul. Interestingly, H. felis genotype I was both detected in a male cub (#3) and two out of five infesting Hyalomma asiaticum ticks.
Conclusions
For the first time, Cytauxzoon manul is reported here from Eurasian lynx. In addition, H. felis has not been known to occur in this host species in China and Central Asia. Thus, the findings of this study extend our knowledge on the geographical distribution and host range of these haemoprotozoan parasites. Moreover, this is also the first evidence of C. manul and H. felis co-infection in Eurasian lynx.

Background
Vector-borne pathogens are the causative agents of several emerging or re-emerging infectious diseases among felines [1, 2]. Nowadays, their epidemiological patterns undergo changes, their geographical ranges tend to expand, and their global incidence rates also increase owing to climatic change and various environmental, demographic and human-related factors [3].
Cytauxzoonosis is an emerging tick-borne disease of domestic cats and wild felids, caused by members of the genus Cytauxzoon (Apicomplexa: Aconoidasida: Piroplasmida: Theileriidae) [4, 5]. The clinic-pathologically most important species, Cytauxzoon felis was described from domestic cat [5], and was thought to be endemic only to North America, specifically in the southern, southeastern, and mid-Atlantic regions of the USA [3, 6]. In North America, the bobcat (Lynx rufus) is the most common natural host for C. felis. Bobcats usually experience a brief and mild illness upon infection, followed by a full recovery [7,8,9]. More recently, Cytauxzoon spp., infecting Eurasian lynx and wild cats in Eurasia, were reported [10].
Hepatozoonosis is a parasitic disease caused by members of the genus Hepatozoon (Apicomplexa: Conoidasida: Coccidia: Eucoccidiorida: Adeleorina: Hepatozoidae). These protozoa infect various mammals, birds, reptiles, and amphibians [11]. Among felids, Hepatozoon felis and other species can cause anorexia, pale mucous membranes, weight loss, pain, diarrhea, vomiting, gait abnormalities, fever, polyuria, polydipsia, and even death in severe cases [12,13,14]. The life cycle of Hepatozoon spp. involves a vertebrate host, which gets infected by ingesting arthropod vectors (e.g., ticks) [13, 15, 16]. The infection can also occur by predation and transplacental transmission [17,18,19].
In this study, Cytauxzoon and Hepatozoon spp. were molecularly screened from Eurasian lynx (Lynx lynx) and their ixodid ticks in northwestern China.
Methods
Sample collection
Three Eurasian lynxes were investigated in this study. According to their anatomy characteristics, body weight, and tooth wear, the sex and age of three lynxes were evaluated [20]. Two of them, an adult female (#1, 4–5 years old) and an adult male (#2, 3–4 years old), were found dead due to natural causes during our field investigation at the China–Kazakhstan border at the West Junggar Mountain in 2018 and 2019, respectively. The third one, a road-killed male cub (#3, 4–6 months old), was also collected in this region in 2019 as already reported in Liu et al. [21]. Five ticks were collected from the male cub, the latter, and molecularly identified as Hyalomma asiaticum [22].
DNA extraction
Genomic DNA was individually extracted from heart, liver, spleen, lung, and kidney samples of three lynxes. The sampled ticks were carefully surface-sterilized, and prior to processing, the exterior of all ticks was disinfected using 3% sodium hypochlorite for 1 min, 70% ethanol for 1 min, and phosphate-buffered saline (PBS) for 1 min. DNA was extracted from whole ticks using TIANamp Genomic DNA Kit (TIANGEN, Beijing, China), with an overnight following the manufacturer’s instructions. DNA extracts were eluted in 60 μL of Tris–EDTA buffer and stored at −80 °C under sterile conditions to prevent contamination until polymerase chain reaction (PCR) analysis.
Polymerase chain reaction amplification
DNA extracts (all from lynxes and five from ticks) were individually screened for the presence of Cytauxzoon and Hepatozoon spp. with PCR and sequencing. For genotyping Hepatozoon spp., 325-, 620-, and 1700-bp-long fragments of the small subunit 18S ribosomal RNA gene (18S rRNA) were chosen [23]. PCR was also performed using primer set of Cytauxzoon, targeting the partial 18S rRNA gene fragment (900bp), 1150 bp fragment of the CytB gene, and 1320 bp fragment of the COI gene [24]. The primers and PCR cycling conditions are shown in Additional file 1. A negative control (distilled water) was included in each run to validate primer-specific amplification. The PCR products were subjected to electrophoresis in 1.5% agarose gel and visualized under ultraviolet (UV) light by staining the gel with Goldview (Biotopped, Beijing, China). All PCR products were purified using the TIANgel Midi Purification Kit (TIANGEN, Beijing, China) and sequenced by Sangon Biotech Co., Ltd. (Shanghai, China) using the same primers.
Sequencing and data analyses
Sequencing data were subjected to Basic Local Alignment Search Tool (BLAST) searches (http://www.ncbi.nlm.nih.gov/blast/) and then aligned and analyzed with reference sequences downloaded from GenBank. Phylogenetic trees were constructed on the basis of the sequence distance method using the maximum likelihood algorithms implemented in the Molecular Evolutionary Genetics Analysis (MEGA) 7.0 software [25]. All sequences from this study were deposited in the GenBank (http://www.ncbi.nlm.nih.gov) database (C. manul 18S rRNA: PP033938; C. manul CytB: PP442054; C. manul COI: PP503316; H. felis 18S rRNA: PP033238, PP528680-PP528683, OR497518, and OR497519).
Results
The results of molecular analysis and sequencing indicated that (i) Eurasian lynx #1 was found to be coinfected with Cytauxzoon manul and Hepatozoon felis; (ii) Eurasian lynxes #2 and #3 were infected with a H. felis genotype I that was significantly the same from that in Hyalomma asiaticum infesting Eurasian lynx cub #3. Phylogenetic trees and BLAST analyses showed that C. manul 18S rRNA gene sequences from this study were grouped with those from Pallas’s cat (Otocolobus manul) in Mongolia (shown in Additional file 2: Fig. S1), and shared 99.89% (871/872) of identities with sequences available in GenBank (AY485690 and AY485691). To assess the genetic variability of Cytauxzoon spp., sequence analyses of mitochondrial COI gene were performed. The results of our phylogenetic analyses indicated a sister group relationship among C. manul and Cytauxzoon spp. from felines (Fig. 1), which was similar to the result based on CytB gene (shown in Additional file 3: Fig. S2). The phylogenetic tree of Hepatozoon spp. based on the partial 18S rRNA gene fragment showed that this genotype was clustered into the clade of “genogroup I”, separately from other isolates of which corresponding sequences are available in GenBank (Fig. 2), and shared 99.94% (1684/1685 bp) of identities with those from Asiatic lion in India (ON075470).

Discussion
This study provides the first evidence for the occurrence of C. manul and H. felis in Eurasian lynx, and this is the first time that infection with H. felis genotype I has been reported in Eurasian lynx and Hyalomma asiaticum ticks in China. To the best of our knowledge, this is also the first report of C. manul and H. felis co-infection in Felid.
Cytauxzoonosis, caused by C. felis, C. manul, and three recently described new Cytauxzoon European species, is an emerging infectious disease that affects wild felids as well as the domestic cat [24, 26, 27]. Cytauxzoon manul is endemic in free-ranging Pallas’s cats (Otocolobus manul) in Mongolia [28], and it was also reported from lions (Panthera leo) in Zimbabwe [29]. More recently, Cytauxzoon spp., different from C. manul, were detected in Romania in four Eurasian lynxes (Lynx lynx) and 12 wild cats (Felis silvestris) [10]. This study reports the first detection of C. manul in Eurasian lynx. Currently, study on C. manul is scarce. In the future, more research is needed to characterize the epidemiology of this species.
Three Hepatozoon species are known to infect felines, including Hepatozoon felis, Hepatozoon canis, and Hepatozoon silvestris [19, 23, 30]. Hepatozoon felis was previously detected in wild cat in the Republic of Cape Verde, in jaguar (Panthera onca) and in jaguarundi (Puma yagouaroundi) in Brazil, in leopard cat (Prionailurus bengalensis) in Korea, and in Eurasian lynx (Lynx lynx) in Turkey, as well as in Asiatic lion (Panthera leopersica), Indian tiger (Panthera tigris tigris), and Indian leopard (Panthera pardus fusca) in India [31,32,33,34,35,36]. H. felis was reported in Haemaphysalis longicornis (Acari: Ixodidae) ticks from free-ranging domestic sheep in Hebei Province, China [37]. In the present study, H. felis genotype I was detected both in a lynx cub and its infecting Hy. asiaticum ticks.
In this study, although H. felis was detected in ticks, it is still impossible determine whether these ticks are truly infected with H. felis. Given that these ticks were engorged, the detection of H. felis DNA in the blood meal was also possible. Therefore, the question of whether Hy. asiaticum ticks can be infected with H. felis still needs further research and confirmation.
Protozoan co-infections are relatively frequent in carnivores [38,39,40,41,42,43]. Although this phenomenon, as also observed in this study, is seldom reported in lynxes, Babesia sp. and H. felis were detected simultaneously in Eurasian lynx in Turkey [34]. Eurasian lynx is included in the Red List of Threatened Species by International Union for Conservation of Nature (IUCN) and is also listed on the second level of National Key Protected Wildlife in China [44]. To better understand the impact of these parasites on the health and conservation status of the Eurasian lynx, future studies should identify its complete pathogen profile by metagenomic next-generation sequencing.
Conclusions
In this study, C. manul and H. felis genotype I were molecularly identified in Eurasian lynx. These two haemoprotozoan parasites caused co-infection in a lynx. Hepatozoon felis was detected both in a lynx cub and its Hyalomma asiaticum ticks. These finding extends our knowledge on the geographical distribution and host range of C. manul and H. felis.
