Special Issue Information

Dear Colleagues,

The pathogens parasitosis, helminth, protozoan, and other parasites are of significance in the health of animals and human beings. Once animals become infected, these pathogens cause mechanical injury, robbing nutrition from the hosts, seriously affecting product performance, and bringing serious economic losses to animal husbandry. For example, fasciolosis is the most widely distributed trematodiasis reported in over 81 countries around the world, which causes annual losses estimated at USD 3.2 billion. Moreover, some important zoonotic parasites such as Toxoplasma gondii and Cryptosporidium are distributed all over the world and threaten both animals and human.

For the sake of animal and human health, studying the epidemic situation of parasites and taking corresponding measures to prevent various parasitic diseases is important, which is a benefit for animal husbandry and public health.

In this Special Issue, we aim to show the most recent research and developments in the epidemiology, disease treatment, control, and prevention strategies of parasitic infection or disease in domestic and wild animals. We welcome both original research papers and reviews dealing with this topic.

This study investigated tick species and spotted fever group rickettsiae (SFGR) infection rates in ticks from yaks in Jiulong County, Sichuan Province, China. Firstly, ticks collected from yaks were meticulously classified through morphological identification. Subsequently, the total DNA of ticks was extracted, and specific partial sequences of their ITS-2 region, as well as the ompA and ompB genes of SFGR, were amplified using PCR. The positive PCR products were sequenced and compared thoroughly against the NCBI database. A phylogenetic analysis was conducted for ITS-2, ompA, and ompB to determine the species of tick and the SFGR. The results revealed that a total of 585 ticks were collected, with the most abundant species being R. microplus, which accounted for 52.65% (308/585) of the total and was followed by I. ovatus (32.99%, 193/585), I. acutitarsus (8.89%, 52/585), and D. everestianus (5.50%, 32/585). Furthermore, SFGR was detected in 63.93% (374/585) of the ticks. Notably, the infection rate of SFGR in semi-agricultural and pastoral areas was significantly higher at 70.60%, compared to 45.10% in pastoral areas (p < 0.01). Overall, this study marks the first investigation into the prevalence of SFGR in Jiulong County and highlights the high infection rate of SFGR in ticks, with R. raoultii being the predominant species.

Giardia duodenalis is a zoonotic parasite that causes gastrointestinal diseases in both humans and animals. To evaluate the prevalence and genetic diversity of G. duodenalis in black goats, we collected 539 fecal samples from nine districts in Fujian Province, China. The presence of G. duodenalis was confirmed through nested PCR targeting the SSU rRNA gene, and genotyping was performed at the beta-giardin, glutamate dehydrogenase, and triosephosphate isomerase loci. Among the samples, 115 tested positive, yielding an overall infection rate of 21.34%. Assemblages A and E were identified, with assemblage E being predominant. Statistical analysis revealed significant regional differences in infection rates (p < 0.01), with Zhangzhou exhibiting the highest infection rate (39%) and Fuzhou the lowest (3.13%). No significant differences in infection rates were observed based on age: 24.56% (56/228) for goats <1 year, 14.92% (27/181) for goats 1–2 years, 26.8% (26/97) for goats 2–3 years, and 18.18% (6/33) for goats ≥ 3 years. Similarly, no significant differences were found between sexes: 24.84% (40/161) for males and 19.84% (75/378) for females. Notably, assemblage A, a zoonotic genotype, was detected, indicating a potential risk of cross-species transmission. This study contributes to a deeper understanding of G. duodenalis in black goats and provides critical data for the development of targeted control strategies in Fujian Province. Full article

Coccidiosis is one of the most significant diseases affecting the rabbit industry and is caused by Eimeria. In a previous study, we identified a new species of Eimeria kongi (E. kongi-ZJK) from the northern region of China (Zhangjiakou, Hebei Province) and studied its pathogenicity and immunogenicity. The aim of this study was to evaluate the pathogenicity, immunogenicity, and cross-immunogenicity from different geographical isolates of E. kongi for vaccine development. Two geographical isolates of E. kongi-QD from Qingdao, Shandong Province (eastern China), and E. kongi-CD from Chengdu, Sichuan Province (southwestern China), were isolated and identified. The pathogenicity, immunogenicity, and cross-immunogenicity among the three geographical isolates were evaluated. The pathogenicity results showed that after infecting rabbits with doses of 1 × 103 or fewer sporulated oocysts of E. kongi-QD and E. kongi-CD, the rabbits exhibited clinical symptoms but recovered quickly, indicating lower pathogenicity. Immunogenicity studies revealed that after immunizing rabbits with 1 × 103 sporulated oocysts of E. kongi-QD and E. kongi-CD for 14 days, followed by challenge with 1 × 104 homologous sporulated oocysts, the oocyst reduction rates in the immunized groups were 99.39% and 99.12%, respectively, compared with the non-immunized groups, demonstrating good immunogenicity. In cross-immunogenicity studies, rabbits were immunized with 1 × 103 sporulated oocysts of E. kongi-ZJK, E. kongi-QD, or E. kongi-CD and then challenged with 1 × 104 sporulated oocysts of heterologous isolate. The immunized groups showed no significant clinical symptoms, and the oocyst reduction rates ranged from 55.9% to 98.4%. E. kongi-CD exhibited cross-protection against E. kongi-ZJK and E. kongi-QD, making it an ideal candidate formulation for vaccine development. Full article

Vector-borne diseases play a significant role in veterinary health, impacting both wild and domestic animals and posing a major constraint on the development of animal husbandry worldwide. The current study aimed to highlight some of the factors involved in the appearance and dissemination of these emerging and re-emerging diseases, as well as the prevalence rate of certain species of pathogens, in cattle throughout Europe. Considering the complexity of vector–host systems, ticks can be mentioned as the first and most common vector involved in the transmission of pathogens in cattle. The highest prevalence was reported for two vector species: Ixodes ricinus and Haemaphysalis punctata. Another factor that contributes to the rapid identification of these diseases is the employed diagnostic method; thus, the most frequently employed techniques in Europe are: PCR, ELISA, and phylogenetic analysis of sequences. The prevalence of tick-borne infections in cattle is continuously increasing. The most frequent associations are Anaplasma spp., Babesia spp., Theileria spp., and Borrelia burgdorferi. Overall, this study highlights a rising occurrence and prevalence of vector-borne diseases in European cattle, underscoring the need for thorough monitoring of farms and vector hotspots—ideally within a “One Health” framework.
