Dogs are the main reservoir of cutaneous and visceral leishmaniasis. A cross-sectional study was conducted to assess leishmaniasis in blood samples from 87 stray dogs (55 without skin lesions and 32 with skin lesions) from shelters in Shiraz, southwest Iran, for the first time. Blood samples were collected from all dogs (with and without skin lesions) and skin lesions from dogs with dermatological lesions. To amplify the conserved region of the <em>Leishmania</em> kDNA minicircle, samples were subjected to a species-specific PCR assay. Skin lesion smears were also assessed by microscopic examination. The PCR amplicons were sequenced, assembled, and multiple-aligned with <em>Leishmania</em> strains retrieved from GenBank. Finally, the phylogenetic analysis was carried out. The results showed 8.05 % (7/87) leishmaniasis in all dogs (with and without skin lesions) and 21.87 % (7/32) in dogs with skin lesions. No <em>Leishmania</em> infection was detected in dogs without skin lesions by PCR. A significant association was found between skin lesions and leishmaniasis (<em>P</em> = 0.001). No significant association was found between sex and infection (<em>P</em> = 0.65). Phylogenetic analysis interestingly identified three species, including <em>L. major</em>, <em>L. tropica</em>, and L. <em>infantum</em>, with 95–98 % identities to documented sequences. Microscopic examination of skin smears confirmed the presence of amastigotes in 15.62 % (5/32) of the dogs with skin lesions. This study highlights the importance of sheltered stray dogs with skin lesions as potential reservoirs in dispersing zoonotic visceral and cutaneous <em>Leishmania</em> spp. in this region. It emphasizes the need for surveillance and control measures in shelters to prevent <em>Leishmania</em> transmission to the vectors, humans, and animal hosts. The study also elucidated that cutaneous parasites, identified more in skin lesions by circulating in dog blood, can be detected using kDNA PCR.</div></div>","PeriodicalId":23600,"journal":{"name":"Veterinary parasitology, regional studies and reports","volume":"60 ","pages":"Article 101244"},"PeriodicalIF":1.4,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143686611","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}

The present study screened dwarf Vechur (<em>Bos indicus</em>) and crossbred (<em>B. taurus</em> × <em>B. indicus</em>) cattle for natural infection to <em>Theileria</em> using peripheral blood smear and clinical and haematology evaluation. Polymorphisms in a previously identified candidate gene were screened in olfactory receptor family 51 sub-family H member-1 (<em>OR51H1</em>, single exon, 948 bp) associated with <em>Theileria</em> tolerance. The association of <em>Theileria</em> resistance/tolerance with different genotypes was also evaluated. <em>Theileria</em> was detected in 32.45 % of crossbred and 6 % of Vechur. Resistance and tolerance to <em>Theileria</em> infection varied significantly across breeds, and Vechur was found resistant (no parasites detected in the blood smear) compared to crossbred (Odds ratio-0.14, 95 % CI- 0.03–0.42, p &lt; 0.01). The <em>OR51H1</em> gene was characterised by sequencing in Vechur cattle, and putative single nucleotide variations (SNVs) were identified by pooled sample sequencing and genotyped using PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism). The five SNVs, T271C, C272T, T362C, G180A and T181G, exhibited polymorphic patterns. SNVs T271C and C272T were tolerant, while T362C, G180A and T181G were non-tolerant. The population was in Hardy-Weinberg equilibrium for SNV G180A in crossbred cattle and for SNVs T271C, C272T, and G180A in Vechur cattle. The SNVs T271C in crossbred and T362C, G180A and T181G in Vechur were significantly associated with <em>Theileria</em> tolerance.

The aim of the current study was to utilise observations on seroconversion of dairy cattle to <em>Fasciola hepatica</em> over the course of a lactation and compare their milk production with other cattle who remained serologically negative throughout the same lactation. Four spring-calving dairy herds on the West Coast of the South Island of New Zealand were selected based on prior knowledge of endemic liver fluke infection. Over the four herds, a total of 485 cows were blood sampled twice during one lactation, in early November (spring) and early March (autumn). The <em>F. hepatica</em> antibody titre of <em>F. hepatica</em> antibody was quantified using a commercial ELISA test (IDEXX Fasciolosis Verification, IDEXX Europe BV, Hoofdorp, The Netherlands). Milk production was estimated by a series of 3–4 herd tests over the lactation where each cow is individually measured during the morning and evening milking on the same day with samples analysed for milk yield, milk fat (MF), protein (MP), lactose (ML) and total milk solids (MS). Energy corrected milk (ECM) was then calculated using the formula: ECM (kg/d) = 12.55 × MF (kg/d) + 7.39 × MP (kg/d) + 0.2595 × milk yield (kg/d). At the spring sampling, 52 % of cows had antibodies detected which increased to 63 % in autumn. For the sampled cows, those that were in the <em>negative</em> IDEXX test category in autumn and spring were categorised as ‘uninfected’ while those which were negative in spring and seroconverted to the <em>strong positive</em> category in autumn were categorised as ‘infected’. Those in the intermediate categories were ignored. A total of 235 cows were categorised as ‘uninfected’ at the spring testing, being in the <em>negative</em> IDEXX diagnostic category. Of those 235, at the autumn testing, 152 remained in the <em>negative</em> diagnostic category and 50 were in the <em>strong positive</em> IDEXX diagnostic category and were categorised as ‘infected’.
