Winter Habitat Influences the Number of Feather Mites of Two Species Living on European RobinsErithacus rubecula

Ardeola (2011)

Ana Regina Nascimento Campos Paulo Catry Manuel de Rojas Stuart Bearhop Jaime A. Ramos

Winter habitat influences the number of feather mites of two species living on European robins Erithacus rubecula.Plumicolous feather mites are a little-known but diverse and abundant group of symbionts of birds. The nature of the feather mite versus bird relationship is controversial, with reports ranging from suggestions of parasitism to evidence supporting commensalism or even mutualism. In addition, little is known as to why enormous inter-individual variation in mite loads is observed within bird species. In this study we show that migrant European robins Erithacus rubecula differ in their load of Proctophyllodes rubeculinus and Trouessartia c.f. rubecula by a factor of 2 to 3 depending on the winter habitat that they occupy. Such variation cannot be explained as being due to robins from different geographic origins wintering in different habitats, as wing shape and stable hydrogen isotope ratios (inferring breeding origin) in feathers of those robins did not explain variation in mite loads. Furthermore, there were no age or sex effects on the number of mites, but abundance increased as winter progressed. Robins wintering in the best putative habitat had higher mite numbers and the fact that there was no correlation between mite infestation levels and either muscle or fat scores indicates minimal costs to the host and hints at a commensal or mutualistic relationship. More research is needed to better understand the factors underlying differences between habitats. Meanwhile, habitat must be taken into consideration in future studies of the relationships between feather mites and birds.

Epidemiology of the children's intestinal parasitism in the Guadalquivir Valley (Spain)

Revista Española de Salud Pública (1997)

Cristina Pérez Armengol Concepción Ariza Astolfi José Manuel Úbeda Ontiveros Diego Benítez Manuel de Rojas

Intestinal parasitism represents a public health problem that should be periodically assessed in each region. In the present paper, a study about prevalence of intestinal parasites, has been carried out in children from the natural region of the Guadalquivir Valley.During the period 1994-1996, 1,917 children without symptoms, aging between 6 and 10, were studied by means of coprological analysis and Graham method, all of them living in 20 villages in the Guadalquivir valley.The overall prevalence of intestinal parasitism have been of 27.12%. The reported parasites and their prevalence are as follows: Enterobius vermicularis (20.44%), Giardia lamblia (5.05%), Entamoeba coli (2.45%), Endolimax nana (1.61%), Entamoeba histolytica (0.31%), Entamoeba hartmanni (0.05%), Iodamoeba bütschlii (0.05%).The overall prevalence of intestinal parasites is similar to that found in other spanish region, if only a little bit more favourable probably due to the long lasting drought and the improvements in health resources, no geohelminths have been detected unlike other protozoan infections, giardiasis maintains a relatively high prevalence.
