Air Sac Nematode ( Serratospiculum tendo) Infection in an Austral Peregrine Falcon ( Falco peregrinus cassini) in Argentina.
(Comité editorial Journal of Wildlife Diseases, 2019-01)We report a case of air sac nematode (Serratospiculum tendo) infection in an adult male Austral Peregrine Falcon (Falco peregrinus cassini) admitted to a rehabilitation center in Mendoza Province, Argentina, in September 2017. This case of air sac nematodes reported in an Argentine raptor is only the second report of S. tendo in South America. We recommend examination of all raptors, especially those falcon species that include insects in their diet and inhabit open lands and those in rehabilitation centers or kept for falconry, education, or captive breeding. Fecal analysis and ... -
Dissemination of visceral leishmaniasis to Western Argentina: When will imported canine vector-borne zoonotic diseases start being local?
(Comité Editorial Journal of Microbiology, Immunology and Infection, 2015-12-15)Visceral leishmaniasis (VL), caused by Leishmania infantum (syn. chagasi), is expanding at an alarming rate in Argentina. In Argentina, VL was first diagnosed in the Northeastern province of Misiones in May 2006,1 with previous reports recording this infection in the neighboring Paraguay much earlier. Since its first diagnosis in Argentina, thousands of cases in dogs and over 100 cases (many fatal) in humans have been diagnosed in several regions of the north and northeastern provinces of Argentina (Figure 1).2,3 The disease has traveled over 1000 km, and so has its vectors and main reservoir, ... -
A Single Nucleotide Polymorphism Translates into a Radical Amino Acid Substitution at the Ligand-Binding Site in Fasciola hepatica Carboxylesterase B
(Comite editorial GENES, 2022-10-19)Fasciola hepatica anthelmintic resistance may be associated with the catalytic activity of xenobiotic metabolizing enzymes. The gene expression of one of these enzymes, identified as car boxylesterase B (CestB), was previously described as inducible in adult parasites under anthelmintic treatment and exhibited a single nucleotide polymorphism at position 643 that translates into a radical amino acid substitution at position 215 from Glutamic acid to Lysine. Alphafold 3D models of both allelic sequences exhibited a significant affinity pocket rearrangement and different ligand-docking modeling ... -
Situación de la fasciolasis en Mendoza: nuevos desafíos de una enfermedad desatendida
(Dirección de Investigación, Ciencia y Técnica. Ministerio de Salud. Mendoza, 2013-03)La fascioliasis es una enfermedad producida por los trematodos Fasciola hepatica y Fasciola gigantica, transmitida por caracoles acuáticos de la familia Lymnaeidae. Tradicionalmente era considerada una enfermedad de importancia veterinaria por el impacto que produce sobre el ganado, únicamente afectando a humanos en forma esporádica. Sin embargo, en años recientes, esta situación ha cambiado en forma drástica: de 2000 casos humanos reportados a nivel mundial entre 1970-1990, actualmente se ven afectados 17 millones de personas y otros 91 millones se encuentran en riesgo. La fascioliasis se ha ... -
Vector Borne Diseases in Mid Western Argentina, First Report of Setaria Equina [Nematoda: Onchocercidae] in A Horse [Equus caballus]
(Comité editorial Austin Journal of Vector Borne Diseases, 2017-12-05)Vector borne diseases are spreading worldwide. Companion animals can be useful as sentinels for disease surveillance. Setaria spp. are filarial nematodes transmitted by Aedes spp. and Culex spp. Setaria equina has been reported in Asia, Africa and North America. This zoonotic nematode is frequently asymptomatic in horses, except during its erratic migrations. Filarial worms have a tropism for ocular and nervous tissues, having important implications in veterinary and public health. In mid west Argentina, Dirofilaria immitis has already been described affecting a woman and dogs. There are no ...
