Genomic DNA was extracted from a single sandfly, and &lt;i&gt;COI&lt;/i&gt; gene was amplified. The amplification product was subjected to bidirectional sequencing. Following sequence assembly, the species of sandflies was characterized through sequence alignment using the BLAST tool. The intra-specific and inter-specific genetic distances of sandflies were estimated among different areas using the software Mega 11, and phylogenetic trees were created. The polymorphisms of nucleotide sequences in the sandflies &lt;i&gt;COI&lt;/i&gt; gene were estimated using the software DnaSP. The fixation index (&lt;i&gt;F&lt;sub&gt;ST&lt;/sub&gt;&lt;/i&gt;) of different geographical isolates of sandflies was calculated using the Arlequin software, and the gene flow value (&lt;i&gt;Nm&lt;/i&gt;) was used to measure the gene flow in the sandflies populations.

In addition, the positive amplification products were sequenced and subjected to genetic evolutionary analysis.</p><p><strong>Results: </strong>The overall prevalence of <i>Anaplasma</i> infections was 17.5% (62/355) in sheep and goats in Anhui Province, and the prevalence of <i>A. bovis</i>, <i>A. phagocytophilum</i>, <i>A. ovis</i> and <i>A. capra</i> infections was 2.8% (10/355), 2.5% (9/355), 2.5% (9/355), and 7.0% (25/355), while the prevalence of <i>A. bovis</i> and <i>A. phagocytophilum</i>, <i>A. phagocytophilum</i> and <i>A. ovis</i>, <i>A. phagocytophilum</i> and <i>A. capra</i> and <i>A. bovis</i>, <i>A. phagocytophilum</i> and <i>A. ovis</i> co-infections was 0.8% (3/355), 1.1% (4/355), 0.3% (1/355) and 0.3% (1/355), respectively. No <i>Anaplasma</i> was detected in the sheep and goat farms in Fengyang County, while at least three <i>Anaplasma</i> species were detected in other sheep and goat farms, with co-infections of multiple <i>Anaplasma</i> species identified. The prevalence of <i>Anaplasma</i> infections was 14.7% (24/163) in goats and 19.8% (38/192) in sheep, and the prevalence of <i>Anaplasma</i> infections was 31.0% (31/100) in goats and sheep under 6 months of age, and 12.2% (31/255) in goats and sheep at ages of 6 months and older, respectively. <i>A. bovis</i>, <i>A. phagocytophilum</i>, <i>A. ovis</i> and <i>A. capra</i> were identified in sheep and goats of different breeds and ages.</p><p><strong>Conclusions: </strong>Multiple <i>Anaplasma</i> species infections were commonly prevalent in goats and sheep in Anhui Province in 2020, notably <i>A. phagocytophilum</i>, <i>A. ovis</i> and <i>A. capra</i>, which have zoonotic risks. Improved surveillance and prevention and control of <i>Anaplasma</i> infections are required in sheep and goats in Anhui Province.</p>","PeriodicalId":38874,"journal":{"name":"中国血吸虫病防治杂志","volume":"36 6","pages":"620-625"},"PeriodicalIF":0.0,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143013507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
