RESUMEN

El objetivo del presente trabajo fue evaluar la pediculosis infantil y otras ectoparasitosis en los hospedadores susceptibles, presentes en el ámbito doméstico de Santa Ana de los Guacaras, Corrientes, Argentina. Se encuestaron 44 hogares. Se evaluaron parasitológicamente 148 niños entre 1 y 14 años de edad y 80 animales domésticos (54 perros, 21 gatos, tres conejos y dos cerdos). Se estableció el grado de contacto de los niños con los animales. La toma de datos ambientales se realizó a través de observación directa del entorno y de la aplicación de encuestas semiestructuradas. La frecuencia global de ectoparasitosis infantil fue 58,8% (87/148). El ectoparásito mas frecuente fue Pediculus capitis, presente en el 56,8% de los niños seguido por Tunga penetrans en el 12,2% y Pulex irritans en el 4,3%. Se observaron dos niños infestados con Ctenocephalides felis y dos con Rhipicephalus sanguineus. Los animales presentaron infestación con R. sanguineus, C. felis, Amblyomma tigrinum, T. penetrans y P. irritans. Todos los niños con piojos presentaron pediculosis activa confirmada. Se destaca el carácter antropo-zoonótico de las pulgas y garrapatas al comprobar la infestación humana y de los animales de compañía con las mismas especies de éstos artrópodos. Los ectoparásitos hematófagos hallados, no solamente en niños en edad escolar sino también en menores de cinco años, demuestra la necesidad de desarrollar estrategias de control a corto plazo.

Englished translated title: PEDICULOSIS AND OTHER PARASITOSIS IN A NORTHEAST ARGENTINE CHILDREN POPULATION

Abstract: The aim of the present investigation was to evaluate infant pediculosis and other ectoparasitosis in susceptible hosts, presents in the domestic environment of Santa Ana de los Guacaras town, in Corrientes, Argentina. Forty four houses were polled. One hundred and forty eight children between 1 and 14 years-old and eighty domestic animals were parasitological evaluated (54 dogs, 21 cats, three rabbits and two pigs). A range degree of contact between children and animals was established. Direct observation of the environment and the application of semi structured polls were performed to collect the data. The global frequency of infant ectoparasitosis was 58.8% (87/148). Pediculus capitis was the most frequent ectoparasite, present in 56.8% of the population, Tunga penetrans in 12.2% and Pulex irritans in 4.3%. Two children infested with Ctenocephalides felis and two with Rhipicephalus sanguineus were observed. The animals presented infestation with R. sanguineus, C. felis, Amblyomma tigrinum, T. penetrans and P. irritans. All the children with lice presented confirmed active pediculosis. Same fleas and ticks species infested human and domestics animals to prove the antropozoonotic character of these arthropods. The infestation was verified in scholar an in less than five years-old, it's necessary to develop control strategies in a short term.

El problema de la pediculosis capitis en escolares del área metropolitana de San José, Costa Rica. (paper in Spanish)

El problema de la pediculosis capitis fue estudiado en 7.312 niños procedentes de 28 escuelas del Area Metropolitana de San José, Costa Rica., mediante observación al ojo desnudo (NEO). De los casos presuntivos se tomó un muestra de cabello o de los supuestos parásitos. Este material fue aclarado y montado en medio Hoyer para su posterior observación microscópica. Se encontraron, 730 (10,0%) niños positivos al menos por una de las siguientes formas parasitarias: huevos eclosionados o no eclosionados, ninfas y adultos de P. humanus capitis. 590 (80,8%) de los positivos fueron niñas y 140 (19,2%) fueron niños. Las tasas de prevalencia observadas en las escuelas estudiadas mostraron valores entre el 3,2 y el 27,2%. Los datos obtenidos sugieren que la pediculosis capitis es uno de los problemas de salud pública más comunes en nuestros niños el cual puede interferir con los procesos de aprendizaje y el bienestar general de la población infantil.

Abstract in English

The problem of pediculosis capitis was studied in 28 schools of the metropolitan area of San José, Costa Rica. 7.312 children were evaluated by naked eye observation (NEO) and a sample of hair or presuntive parasite forms was collected in all the suspected cases of pediculosis capitis. This material was cleared and mounted in Hoyer’s medium for microscopic observation. 730 (10.0%) of the testedchildren were positive at least for one of the following parasite forms: hatched or non-hatched eggs, nymphs and adults. 590 (80.8%) of the positive children were girls and 140 (19.2%) were boys.The prevalence rates observed in the studied schools showed values between 3.2 and 27.2%. These data suggest that pediculosis capitis is one of the most common public health problems in our children, that can interfere with their learning processes and general welfare.

Six species of lice (Phthiraptera: Philopteridae, Menoponidae) were collected from four marine bird species belonging to the family Laridae from the Chilean coast. Saemundssonia sternae (Linnaeus, 1758) and Quadraceps sellatus (Burmeister, 1838) collected from the boreal sea gull (Sterna hirundo, Linnaeus,1758), Saemundssonia lari (O. fabricius, 1780), Quadraceps punctatus (Burmeister, 1838) and Q. ornatus (Grube, 1851) found on the Dominican sea gull (Larus dominicanus, Lichtenstein, 1832); Q. punctatus collected from garuma sea gull (L. modestus Tschudi, 1843) and S. lari and Actornithophilus piceus lari (Packard,1870) found on Franklin sea gull (L. pipixcan Wagler,1831). All these species of Phthiraptera are first reports in Chile.

The parasites of 40 Lepus europaeus (hares) were analyzed (20 of the Ñuble Province and 20 of Ultima Esperanza) caught between January 2003 and August 2004. In the Ñuble province three endoparasites species were isolated: Trichostrongylus retortaeformis (60%), Passalurus ambiguus (5%) and Eimeria spp. (45%). In Ultima Esperanza only T. retortaeformis was isolated with 60% of infection. The ectoparasite species isolated corresponded to the Phthiraptera Haemodipsus lyriocephalus in a hare of the Ñuble Province. No significant differences in the presence of gastrointestinal parasites were found with respect to sex and age of the hare. Nor was there any significant difference between parasitism of T. retortaeformis in the two studied zones.

...An 87.5% of birds were parasitised by one or more of the following louse species: Holomenopon brevithoracicum, Anaticola marginella, Anatoecus dentatus and Anatoecus icterodes, all of them belonging to the Order Phthiraptera. All these species represent new louse records from Magellan geese for Chile, as well as a new host-louse record for A. dentatus on C. picta.
