This study was undertaken to determine whether image texture derived from high spatial resolution imagery could successfully predict Sirex noctilio infestation levels in a pine plantation forest in the eastern part of South Africa. The woodwasp, S. noctilio, damages trees by releasing toxic mucus into the wood during oviposition. A 50 × 50 m grid was generated over the study area and 65 cells w...

Although the practice of infectious diseases involves a broad range of surgical and medical disciplines, interactions with psychiatry are infrequent. Delusional infestation is a condition where an individual has a firmly fixed false belief that they have an infection. Delusional infestation challenges the infectious diseases specialist who must diligently rule out the presence of a true infecti...

results a total number of 20 out of 1772 (1.12%) examined students were found to be infested by lice. although the infestation rate was higher in girls, the difference of infestation rate between genders was not statistically significant (p > 0.05). the rate of head lice infestation was siginificantly (p < 0.05) correlated to their hair-washing behavior. parents’ literacy level also was siginif...

purpose : to report for the first time, a presumable case of pediculus capitis corneal pseudo-infestation case report : our patient was a 35-year-old farmer presenting with symptoms and signs of ocular discomfort and inflammation. clinical examination suggested a retained corneal foreign body pathology of the lesion suggested a female pediculus humanus capitis (head louse). conclusion : arthrop...

&nbsp; Background: Head lice infestation is one of the most common parasitic infections with a long history in the world . The purpose of this study was to determine the prevalence of head lice infestation among 3-6 years old children going to nursery schools in Kashan, Iran in 2009. &nbsp; Materials and Methods: This cross-sectional study was performed on 1200 children having the age range ...

BACKGROUND The eco-epidemiological status of Chagas disease in the Monte Desert ecoregion of western Argentina is largely unknown. We investigated the environmental and socio-demographic determinants of house infestation with Triatoma infestans, bug abundance, vector infection with Trypanosoma cruzi and host-feeding sources in a well-defined rural area of Lavalle Department in the Mendoza provi...

BACKGROUND Failure to detect a disease agent or vector where it actually occurs constitutes a serious drawback in epidemiology. In the pervasive situation where no sampling technique is perfect, the explicit analytical treatment of detection failure becomes a key step in the estimation of epidemiological parameters. We illustrate this approach with a study of Attalea palm tree infestation by Rh...

BACKGROUND The Norway rat (Rattus norvegicus) is the principal reservoir for leptospirosis in many urban settings. Few studies have identified markers for rat infestation in slum environments while none have evaluated the association between household rat infestation and Leptospira infection in humans or the use of infestation markers as a predictive model to stratify risk for leptospirosis. ...

Plants respond to various types of herbivore and pathogen attack using well-developed defensive machinery designed for self-protection. Infestation from phloem-sucking insects such as whitefly and aphid on plant leaves was previously shown to influence both the saprophytic and pathogenic bacterial community in the plant rhizosphere. However, the modulation of the root microbial community by pla...

conclusions the overall infestation rate in the present study is probably one of the lowest infestation rates in iran and in the region. it appears necessary to examine pupils by trained persons for early detection of infestation. results according to the obtained results, pediculosis spp. prevalence was 2% among male and female students of khorramshahr primary schools; it was 2.6% in females a...
