The first case report of canine trypanosomiasis, a consequence of Trypanosoma evansi infection, is presented in this Peruvian study. The dog, displaying severe clinical symptoms, passed away at a veterinary clinic situated in the Peruvian Amazon region of San Martín. A microscopic analysis of blood and bone marrow samples confirmed the presence of trypomastigotes, and postmortem histological evaluation indicated damage to the heart, lungs, kidneys, and spleen. Collected specimens, subject to nested-PCR testing, demonstrated the presence of Trypanosoma spp., yet were devoid of T. cruzi. The infecting species, as identified by high-throughput sequencing, demonstrated a close kinship to *T. equiperdum/evansi*, a conclusion bolstered by subsequent phylogenetic analysis, which established a relationship with *T. evansi*. The discovery of *T. evansi* in this region underscores the critical need for enhanced surveillance measures to assess the impact of surra on this area and to establish preventive strategies to mitigate the socio-economic consequences of animal infections, both in domesticated and farmed animals, as well as to prevent potential transmission to humans.

For agricultural productivity, the black-faced ibis, Theristicus melanopis, is recognized for its role in eliminating a wide range of invertebrate and vertebrate pests. Though it is a frequent occurrence in Chilean ecosystems, details about its parasitic organisms are restricted. The research's principal objective was to retrieve data on the diversity of ectoparasites and gastrointestinal helminths affecting black-faced ibises in the communes of Valdivia and Panguipulli, Los Rios region. Mycobacterium infection The Centro de Rehabilitacion de Fauna Silvestre (CEREFAS-UACh), located at the Universidad Austral de Chile in Valdivia, provided 74 specimens for examination between 2011 and 2015. To ascertain the presence of ectoparasites, black-faced ibises were visually inspected, and necropsies were undertaken to identify internal parasites in their respiratory and digestive organs. Epigenetic outliers Across each taxonomic classification, the parasite prevalence, mean intensity, mean abundance, and range were ascertained for each bird. The observed species comprised five ectoparasites and six helminths. Representing four different species, a total of 298 lice (Insecta Phthiraptera) were collected. These included Ardeicola melanopis (1351%), Colpocephalum trispinum (2027%), Ibidoecus fissisignatus (405%), and Plegadiphilus mamillatus (946%). Of particular interest was the isolation of a feather mite species, Diodochaetus melanopis, categorized under Acari Pterolichoidea. This represented 1756% of the total. Within 48 black-faced ibis (comprising 6486% of the population), a substantial 1229 gastrointestinal helminths were detected. These included two nematodes, Porrocaecum heteropterum (5541%) and Baruscapillaria obsignata (2432%); one tapeworm, Eugonodaeum nasuta (2027%); two digeneans, Echinoparyphium recurvatum (135%) and Strigea bulbosa (676%); and the acanthocephalan, Sphaerirostris sp. The JSON schema is designed to return a list of sentences. BMS-986449 mouse New host-parasite relationships are unveiled by the findings concerning the parasites P. mamillatus, D. melanopis, B. obsignata, E. recurvatum, S. bulbosa, and Sphaerirostris sp. The Chilean animal community now boasts the louse P. mamillatus, the feather mite D. melanopis, the platyhelminths E. nasuta, E. recurvatum, and S. bulbosa, and the acanthocephalan Sphaerirostris sp. as newly documented species.

This study investigated the prevalence and contributing factors of gastrointestinal parasite infections in horses managed under diverse systems within Santa Catarina, Brazil, aiming to comprehensively assess the impact of parasitism on equine health and the broad spectrum of parasitic species involved. Samples from 208 horses were stratified as follows: 91 horses from extensive systems, 64 from semi-extensive systems, and 53 horses from intensive systems. The identified helminth species, including those from the Strongylida order (80.29% of the total), comprised Parascaris equorum (336 specimens), Oxyuris equi (433 specimens), and the Anoplocephala spp. The JSON schema produces a sentence list as output. By scrutinizing coproculture results, a variety of Strongylida order parasites, including Strongylus vulgaris, S. edentatus, S. equinus, Triodontophorus spp., Trichostrongylus axei, and members of the Cyathostominae subfamily, such as Gyalocephalus capitatus and Poteriostomum species, were characterized. A positive protozoa sample was present only in the Cryptosporidium spp. group. This JSON schema returns a list of sentences. Within the animal husbandry model, the extensive system yielded a larger percentage of infected horses and a greater likelihood of infection compared to the other rearing approaches. Only cyathostomin infections displayed a noteworthy difference in co-grazing scenarios with cattle, which also showed a relatively low infection risk. This study demonstrated a substantial occurrence of equine gastrointestinal parasites, primarily strongylids, emphasizing the prevalence of small strongylids. Beyond the infection factors, horse management procedures were found to be indispensable in controlling parasite problems.

For the global livestock industry, gastrointestinal parasites in small ruminants represent a substantial economic and animal welfare challenge, causing severe problems. Anthelmintic resistance in *H. contortus* affecting small ruminants is a grave concern, as it jeopardizes parasite management efforts and diminishes animal productivity. Resistance to benzimidazoles (BZ) within Haemonchus populations infecting goats and sheep in Uganda remains poorly documented. To gauge the prevalence of gastrointestinal parasites and pinpoint the presence of benzimidazole resistance mutations within the α-tubulin isotype 1 gene of Haemonchus contortus in goats from selected Ugandan districts was the objective of this study. For H. contortus adult worm analysis, 200 goats from 10 districts within Uganda were sampled after being slaughtered at the Kalerwe abattoir in Kampala. The collection of faecal samples was also performed to identify the presence of any additional intestinal parasites. By employing flotation and sedimentation techniques, microscopic analysis and examination of the faeces were accomplished. To identify *H. contortus* species and ascertain the presence of mutations linked to anthelmintic resistance, DNA was extracted from adult worms, followed by PCR and sequencing of the ITS-2 region and β-tubulin isotype 1 gene. Intestinal parasite analysis via faecal microscopy revealed a significant prevalence of coccidia (98%), followed by strongyles (975%), Strongyloides (82%), Paramphistomum (745%), Moniezia (46%), Fasciola (15%), and Trichuris (1%). Goats generally displayed a substantial intestinal burden of coccidia (5000 oocysts per gram) and strongyles (1000 eggs per gram), with percentages of 65% and 675% respectively. A significant proportion, 63% (126 specimens out of a total of 200), of the studied samples exhibited the presence of adult H. contortus worms. Analysis of the partial -tubulin isotype 1 gene in 54 Haemonchus contortus adult male isolates exhibited mutations indicative of anthelmintic resistance. In samples possessing adequately sequenced beta-tubulin, the most prevalent mutation was F200Y, affecting 13% of the samples. E198A and E198K mutations followed, both present in 9% of the sequenced samples. In none of the examined samples was mutation F167Y detected, nor were there any heterozygous individuals carrying the SNPs linked to BZ resistance that our research uncovered. The significance of this research lies in its emphasis on the need for careful anthelmintic application, specifically benzimidazoles, to maintain effective H. contortus control in Uganda, and its call for further investigation into parasite resistance observed in other species studied.

Myianoetus, classified within the Histiostomatidae mite family, has a phoretic relationship with flies. Forensic investigations may find value in the connection between flies and phoretic mites, with the associated development of flies on decomposing human bodies. In summary, these elements might be valuable for determining when an individual died. In this Iranian research, the first recordings of Myianoetus muscarum deutonymph phoretic relationships with adult Musca domestica are presented. Exploring any connection between phoretic mites and flies requires further investigation.

At the Veterinary Teaching Hospital of the School of Veterinary Medicine in Trinidad and Tobago, a 3-year-old domestic shorthair female cat was examined, exhibiting a swollen nose and multiple, differently sized small tumors on both ears. The initial diagnostic suite included a comprehensive blood panel, a serum chemistry profile, cytological assessments of the ear and nasal masses, and the determination of FeLV/FIV status. The CBC and biochemistry results demonstrated no significant findings, other than the presence of hyperproteinaemia and hyperglobulinemia. Examination of the nose and ear lesions through cytology revealed a mixed inflammatory condition along with a significant count of intracellular and extracellular organisms, implying Leishmania amastigotes. Regarding the cat's FeLV/FIV status, the test indicated no infection. Subsequently, histopathology, Leishmania IFA, and PCR analysis were conducted, validating the Leishmania diagnosis. Through the process of PCR, DNA sequencing, and phylogenetic tree analysis, L. amazonensis was definitively identified. Trinidad's first observed case of L. amazonensis infection in a domestic animal, with molecular characterization, demonstrates the parasite's presence and potential for sandfly-mediated transmission.

In tropical and subtropical regions, the globally distributed insect Telmatoscopus albipunctata is recognized as a member of the Psychodidae family. While not possessing hematophagous behaviors, it plays a crucial role in veterinary medicine, due to its ability to mechanically transmit protozoa and bacteria, many of which subsequently cause nosocomial infections. A rare case of accidental urinary myiasis caused by T. albipunctata, a dipteran, is detailed in this report, specific to Brazil. This report's objective is to describe this occurrence, considering that this species, implicated in human myiasis in other countries, had not yet been registered in South America.
