Molecular Identification and Genotyping of Cryptosporidium spp. and Blastocystis sp. in Cattle in Representative Areas of Shanxi Province, North China.

ABSTRACT: Both Cryptosporidium spp. and Blastocystis sp. are common intestinal protozoa, which can cause zoonotic diseases and economic losses to livestock industry. To evaluate the prevalence and genetic population structure of Cryptosporidium spp. and Blastocystis sp. in beef and dairy cattle in Shanxi Province, north China, a total of 795 fecal samples were collected from beef and dairy cattle in three representative counties in Shanxi Province, and these fecal samples were examined using molecular approaches based on 18S small-subunit ribosomal RNA (SSU rRNA) of Cryptosporidium spp. and Blastocystis sp., respectively. Among 795 cattle fecal samples, 23 were detected as Cryptosporidium-positive and 103 were detected as Blastocystis-positive, and the overall prevalence of Cryptosporidium spp. and Blastocystis sp. in cattle in Shanxi Province was 2.9% and 13.0%, respectively. For Cryptosporidium spp., DNA sequence analysis indicated that all 23 positive samples were identified as C. andersoni. Furthermore, five known subtypes (ST1, ST10, ST14, ST21 and ST26) and three unknown subtypes of Blastocystis sp. were detected among 103 positive samples using DNA sequence analysis. This study reported the occurrence and prevalence of Cryptosporidium spp. and Blastocystis sp. in cattle in Shanxi Province for the first time, which extends the geographical distribution of these two zoonotic parasites and provides baseline data for the prevention and control of these two important zoonotic parasites in cattle in Shanxi Province.

Project description:BackgroundThe intestinal protozoa Entamoeba spp. can infect humans and various animals, including donkeys, causing diarrhea and malabsorption and presenting significant risks to animal husbandry and public health. Most Entamoeba species are not pathogenic except for Entamoeba histolytica. China has among the highest rates of donkey farming worldwide. Donkey (Equus asinus) farming is increasingly important in China because of their draft and medicinal value; however, epidemiological data on Entamoeba spp. in donkeys remains limited globally. This study aimed to investigate the prevalence of Entamoeba in donkeys in Shanxi Province, North China, and assess associated risk factors using a molecular approach.MethodsFecal samples of 815 donkeys from three representative geographical locations in Shanxi Province were collected to investigate the presence of Entamoeba spp. A portion of the small-subunit rRNA gene (SSU rRNA) was amplified and sequenced to determine the prevalence and species/genotypes of Entamoeba spp. Statistical analysis of possible risk factors was performed using Statistical Product and Service Solutions (SPSS) 26.0 software. The phylogenetic relationship of Entamoeba spp. was reconstructed using the neighbor-joining (NJ) method in Molecular Evolutionary Genetics Analysis (Mega) 7.0 software.ResultsThe overall prevalence of Entamoeba spp. in donkeys in Shanxi Province was 7.12% (58/815). Two species (Entamoeba sp. RL9 and Entamoeba equi) were identified by sequence analysis; of these, Entamoeba sp. RL9 was the most prevalent species in donkeys in this study. Statistical analysis revealed that the donkeys' sex, region, age, and altitude are the risk factors associated with Entamoeba spp. prevalence (P < 0.05). Phylogenetic analysis indicated that the sequences of Entamoeba sp. RL9 and E. equi isolated from donkeys in this study were clustered with previously reported animal-derived Entamoeba sp. RL9 and E. equi sequences, respectively.ConclusionsThis study reports the occurrence and prevalence of Entamoeba spp. in donkeys worldwide for the first time to our knowledge. This not only expands the geographical distribution but also broadens the host range of Entamoeba spp., addressing the knowledge gap regarding the prevalence of Entamoeba spp. in donkeys, providing baseline data for carrying out prevention and control of Entamoeba spp. in donkeys in China.
