Suitability of wild decapods from an alluvial valley in South America for human nutrition as derived by amino acid composition
(Elsevier, 2025-01)Decapods are abundant in freshwater environments of tropical and subtropical rivers and could be considered a good resource for human feeding. The present study evaluated the nutritional quality of decapods in relation to ... -
Tick-borne pathogens in raccoons (Procyon lotor) from Germany
(Elsevier, 2025-03)Germany is harbouring the majority of Europe's raccoon population, which are considered as invasive neozoa. Many zoonotic pathogens are found in wild raccoons worldwide, but there is a lack of eco-epidemiological data for ... -
Theileria cervi in Amblyomma neumanni (Acari: Ixodida, Ixodidae) collected on horses from North-western Argentina
(Springer, 2025-01)Amblyomma neumanni ticks collected on horses from the North-West of Argentina were analyzed for the presence of the Piroplasm agents Babesia and Theileria. A total of 97 adult ticks from four different provinces (Jujuy, ... -
Failure of doramectin and ivermectin in preventing Cochliomyia hominivorax myiasis in a subtropical region: A pharmacokinetic-pharmacodynamic study
(Elsevier, 2025-02)The aim of this work is to present a case study where the failure of IVM 3.15 % and DRM 1 % to prevent natural infestations of C. hominivorax larvae in Argentina is investigated based on field efficacy tests and a ... -
Evaluation of the transmission of Anaplasma marginale by Amblyomma tonelliae
(Elsevier, 2025-02)This study aimed to evaluate A. marginale transstadial (TST) and transovarial transmission (TOT) by Amblyomma tonelliae through vector competence assays and analysis of natural infection in free-living ticks. This three-host ... -
