Trombiculiasis in a dog with severe neurologic disorders spain
Emerging Infectious Diseases, 2020Co-Authors: Paula Santibanez, Eva Gallo, Ana M Palomar, Aranzazu Portillo, Jose A Carrillo, Jose A OteoAbstract:Chiggers, the larvae of trombiculid mites, parasitize a wide variety of terrestrial vertebrates worldwide. Their bites cause seasonal Trombiculiasis in humans and animals. Affected canines can have a variety of digestive and systemic clinical signs. We describe a case of canine Trombiculiasis in a dog exhibiting severe neurologic symptoms.

Neotrombicula inopinata (Acari: Trombiculidae) – a possible causative agent of Trombiculiasis in Europe
Parasites & Vectors, 2014Co-Authors: Alexandr A. Stekolnikov, Paula Santibanez, Ana M Palomar, Jose A OteoAbstract:Background For over a decade, the presence of trombiculid mites in some mountain areas of La Rioja (Northern Spain) and their association with seasonal human dermatitis have been recognized. This work aimed to establish the species identity of the agent causing Trombiculiasis in the study area. Methods Trombiculid larvae (chigger mites) were collected from vegetation in the Sierra Cebollera Natural Park and in Sierra La Hez during an outbreak of human Trombiculiasis in 2010. Three specimens collected from a bird were also examined. Identification was made using morphological and morphometric traits based on the most recent taxonomic sources. A comparison of those mites with specimens of the same species collected throughout Europe was performed by means of cluster analysis with multiscale bootstrap resampling and calculation of approximately unbiased p-values. Results All collected mites were identified as Neotrombicula inopinata (Oudemans, 1909). Therefore, this species is the most likely causative agent of Trombiculiasis in Spain, not Neotrombicula autumnalis (Shaw, 1790), as it was generally assumed. No chigger was identified as N. autumnalis in the study area. Neotrombicula inopinata clearly differs from N. autumnalis in the presence of eight or more setae in the 1st and 2nd rows of dorsal idiosomal setae vs. six setae in N. autumnalis . Comparison of N. inopinata samples from different locations shows significant geographic variability in morphometric traits. Samples from Western and Eastern Europe and the Caucasus formed three separate clusters. Conclusion Since the taxonomical basis of many studies concerning N. autumnalis as a causative agent of Trombiculiasis is insufficient, it is highly possible that N. inopinata may be hiding behind the common name of “harvest bug” in Europe, together with N. autumnalis .

trobiculidos y Trombiculiasis en la rioja
2015Co-Authors: Paula SantibanezAbstract:Los trombiculidos son acaros de distribucion mundial pertenecientes a la familia Trombiculidae. Algunos generos tienen gran importancia en medicina humana y veterinaria. En America y Europa se asocian a cuadros clinicos de dermatitis pruriginosas estacionales (Trombiculiasis). En el Sudeste Asiatico e Islas del Pacifico son los vectores reconocidos del tifus de los matorrales. Su potencial papel en la transmision de otras enfermedades infecciosas se desconoce. Los objetivos de este trabajo fueron: 1) Descripcion de la epidemiologia de la Trombiculiasis en La Rioja; 2) Identificacion del agente causal y su ciclo biologico; 3) Estudio de la presencia de Rickettsia spp., Anaplasma phagocytophilum, Borrelia spp., Coxiella burnetii, Bartonella spp. y Orientia tsutsugamushi en trombiculidos y 4) Descripcion clinica de la Trombiculiasis en La Rioja. Nuestros datos han puesto de manifiesto la coincidencia de la estacionalidad de los cuadros de Trombiculiasis humana y canina con la presencia de larvas de trombiculidos en la vegetacion de zonas definidas en La Rioja. Se ha descrito la presencia de N. inopinata por primera vez en Espana. La identificacion de esta especie de trombiculidos en la epoca y lugar donde se producian los casos de Trombiculiasis, implica epidemiologicamente a N. inopinata como agente causal de esta afeccion. En la zona de estudio, se encontraron larvas de N. inopinata en la vegetacion desde mediados de verano hasta finales de otono. Los ejemplares adultos de esta misma especie se detectaron en el suelo durante la primavera. Las larvas de trombiculidos retiradas de aves, potencialmente migratorias, se clasificaron tambien como N. inopinata. En nuestro medio, no tenemos evidencia de que los trombiculidos esten infectados por Rickettsia spp., A. phagocytophilum, Borrelia spp., C. burnetii, Bartonella spp. ni O. tsutsugamushi. No obstante, su papel como causantes de Trombiculiasis humanas y caninas ha de ser tenido en cuenta desde el punto de vista de la Salud Publica. En las personas, los trombiculidos producen cuadros clinicos molestos de dermatitis muy pruriginosas, mientras que los perros sufren parasitaciones masivas con procesos graves que pueden llegar a ser fatales. La unica medida de prevencion eficaz es evitar el contacto con la vegetacion en aquellas zonas donde se ha documentado la presencia de trombiculidos. Por tanto, se deben impulsar campanas que informen a la poblacion del riesgo de sufrir Trombiculiasis en La Rioja.

Chigger mites of the genus Ericotrombidium (Acariformes: Trombiculidae) attacking pets in Europe
Veterinary Parasitology, 2016Co-Authors: Alexandr A. Stekolnikov, Helga Waap, Jacinto Gomes, Tânia AntunesAbstract:Abstract Diversity of chigger mites causing Trombiculiasis of domestic animals and humans in Europe is greatly underestimated. A number of reports on the attacks of “harvest mite” (Neotrombicula autumnalis) could be based on misidentified chiggers from other species and genera. In this study descriptions of two cases of Trombiculiasis are presented, which constitute the first report on the pets’ parasitism by the chigger genus Ericotrombidium in Europe. The species Ericotrombidium ibericense is for the first time reported in Portugal as a causative agent of the Trombiculiasis entailed extensive alopecic lesions and pruritus in a cat. Ericotrombidium geloti is for the first time reported as a cause of canine Trombiculiasis in Crimea. Presence of other Ericotrombidium species on man and domestic animals is highly probable in countries of the Mediterranean basin.

Trombiculiasis caused by chigger mites eutrombicula acari trombiculidae in peruvian alpacas
Veterinary Parasitology, 2012Co-Authors: Luis A Gomezpuerta, Juan Olazabal, Maria T Lopezurbina, Armando E GonzalezAbstract:Trombiculiasis is an infestation caused by larvae members of the family Trombiculidae, common called chigger mites. In this study is presented the first case of Trombiculiasis caused by the infestation of chigger mite Eutrombicula in alpacas from Peru. Twenty-two alpacas of a total of 130 animals were infested by Eutrombicula sp. The chigger mite location was only in the face skin folds and around the eyes. In addition, all alpacas infested had alopecia and dermatitis in the infected zone.
