Health burdens associated with poor housing and indoor pest infestations are likely to affect young children in particular, who spend most of their time indoors at home. We completed environmental assessments in 644 homes of pregnant Latina women and their children living in the Salinas Valley, California. High residential densities were common, with 39% of homes housing > 1.5 persons per room....
Monitoring programs increasingly are used to document the spread of invasive species in the hope of detecting and eradicating low-density infestations before they become established. However, interobserver variation in the detection and correct identification of low-density populations of invasive species remains largely unexplored. In this study, we compare the abilities of volunteer and exper...
The most important ectoparasites infesting/infecting alpaca (Vicugna pacos) and llama (Lama glama) are reviewed. The clinical manifestation and the diagnosis of the different parasitic infections/infestations of Sarcoptes scabiei, Chorioptes sp., Psoroptes sp., Damalinia (Bovicola) breviceps and Microthoracius spp. are described as well as therapies against them. Demonstrating S. scabiei and Ch...
Proteins extracted from salivary glands of unfed, three days and five days fed adult Hyalomma marginatum marginatum were analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). We have noticed changes during the three feeding steps. Some proteins disappeared during feeding process (23, 38, 39, 40 to 50, 95 and 112 kDa), they might be proteins which were converted in ot...
Identification and eradication of murine fur mite infestations are ongoing challenges faced by many research institutions. Infestations with Myobia musculi and Myocoptes musculinus can lead to animal health problems and may impose unwanted research variables by affecting the immune and physiologic functions of mice. The purpose of this study was to evaluate the utility and efficacy of soiled be...
Virtually every higher animal, including man, is parasitized by species of lice. Pediculosis is important economic problem of many species of livestock (Figure 4) and poultry and at present the lice only be controlled with insecticides (Figure 5). This review deals with the principal classes of insecticides available to control these pests cattle, pigs, sheep and poultry and particular attentio...
