Climate change, landuse modifications, and increasing interactions between domestic animals, wildlife, and humans have resulted in changes in tick-host dynamics and the emergence of novel pathogens worldwide. Therefore, describing the host and geographic ranges of vector species is essential in assessing disease risk, especially in understudied areas, and should be conducted in a One Health context. In sub-Saharan Africa, previous work on ticks has focused primarily on those species most relevant to domestic livestock or humans, highlighting a significant knowledge gap concerning species of ticks that infest domestic animals in rural areas. The objective of this study was to investigate the species diversity of ticks on domestic dogs in rural areas of Chad, Africa. From 2019 to 2022, we collected 3412 ixodid ticks from 435 domestic dogs from 23 villages in Chad, Africa during both dry and wet seasons. Ticks were identified to species using morphological techniques and/or molecular analyses of the 16S rDNA, 12S rDNA, and cytochrome oxidase I gene regions. We identified 11 species of ticks from dogs including <em>Amblyomma variegatum</em>, an <em>Amblyomma marmoreum</em> complex species, <em>Haemaphysalis leachi,</em> a <em>Haemaphysalis</em> sp., <em>Hyalomma impressum, Hyalomma truncatum, Rhipicephalus decoloratus, Rhipicephalus guilhoni, Rhipicephalus muhsamae, Rhipicephalus linnaei</em> (=<em>R. sanguineus</em> ‘tropical lineage’), and a <em>Rhipicephalus</em> sp. Several of these tick species are known vectors for important canine and zoonotic pathogens and some are more commonly associated with cattle hosts.

The present study aimed to detect and characterize cases of sarcoptic mange in herds of llamas (<em>Lama glama</em>) raised in the high plateau region (Puna) of the province of Jujuy, Argentina. Mange-compatible lesions were found in 2 out of 45 examined llama herds, in which 7 and one affected animals were detected.

Histopathology of skin biopsies revealed scarce mixed inflammatory infiltrate in the dermis and few acari in the epidermis, or abundant infiltrate and numerous acari, accompanying these two presentations, respectively.

Microscopic screening and 18S rRNA gene-targeted PCR identified 0.25 % (1/401) and 0.5 % (2/401) of samples, respectively, as positive for <em>Cryptosporidium</em> spp. The genetic sequences of the 18S rRNA, HSP-70, actin, and GP60 genes showed genetic similarity to <em>Cryptosporidium wrairi</em> sequences of 99.07 %, 99.69 %, 99.57 %, and 91.51 %, respectively. Genetic sequencing and phylogenetic analyses identified the novel GP60 subtype family VIIbA13 of <em>C. wrairi</em>. In conclusion, we report in this study a low prevalence of the novel GP60 subtype family VIIbA13 of <em>C. wrairi</em> in free-living capybaras from urban areas of the state of Mato Grosso do Sul, Brazil. We propose that capybaras act as a novel host for <em>C. wrairi</em>.</div></div>","PeriodicalId":23600,"journal":{"name":"Veterinary parasitology, regional studies and reports","volume":"57 ","pages":"Article 101152"},"PeriodicalIF":1.4,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142652779","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}

This parasite affects dogs, and infections may lead to neuromuscular problems in them. Likewise, dogs can act as sentinels for toxoplasmosis, providing valuable information on the prevalence of the parasite in a given area. Therefore, the aim of the present study was to determine the seroprevalence of <em>T. gondii</em> in dogs from Lima City in Peru. A total of 120 sera from domestic dogs were used to detect IgG antibodies using the modified agglutination test (MAT). Forty dogs tested positive for the MAT, indicating a seroprevalence of 33.3 % (CI<sub>95%</sub> 24.9–41.8 %). Only the variable sex demonstrated a statistical association with exposure to <em>T. gondii</em> in dogs, with males exhibiting odds of 2.40 (CI<sub>95%</sub> 1.10–5.37) compared to females. Since dogs are the main human pet, they could act as sentinels to estimate the situation of toxoplasmosis in humans. Our findings highlight the need to continue epidemiological surveillance of <em>T. gondii</em> in canine populations in various localities of Peru.</div></div>","PeriodicalId":23600,"journal":{"name":"Veterinary parasitology, regional studies and reports","volume":"57 ","pages":"Article 101153"},"PeriodicalIF":1.4,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142652778","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}
