The German cockroach, Blattella germanica, is a major structural pest, and cockroach allergens have been linked to the development and exacerbation of allergic disease and asthma in cockroach sensitive individuals. The inner-city residential environment often supports large cockroach infestations, which expose residents to high levels of allergens. This review summarizes information on the publ...

background : cockroaches are of vital importance medically and hygienically. they are able to contaminate foods and act as vectors of pathogenic agents such as bacteria, protozoa, and parasites to human environment either mechanically or through their digestive system. cockroaches belong to the phylum arthropoda, class insecta, and order blattodea or blattaria. to date, over 4,500 cockroach spe...

background: baits have become popular and effective formulations against urban insect pests. compared with re­sidual sprays toxic gel baits are used more and more frequently to control urban cockroach populations. the aim of this study was to investigate the usage of two commercially available fipronil and imidacloprid gel bait formulations against blattella germanica field infested in iran. me...

background: asthma is the most common chronic disease of childhood. exposure to allergens plays an important role in asthma. recently, cockroach has attracted attentions as an important allergen.   objective: to evaluate cockroach allergy in iranian children with asthma.   methods: 100 children with asthma were studied. after determination of asthma severity, serum total ige and blood eosinophi...

Cockroach suppression is fundamental to cockroach allergen mitigation in infested homes. The effects of various cockroach control strategies on cockroach populations and allergen concentration have not been examined in schools. This study was conducted to compare the effectiveness of integrated pest management (IPM) and conventional pest control in controlling German cockroach (Blattella german...

BACKGROUND Studies have demonstrated that IgE-binding cross-reactive epitopes between shrimp, cockroach, and house dust mite tropomyosins can account for the presence of detectable IgE to shrimp in patients with cockroach and dust mite allergies. OBJECTIVE We investigated the correlation between IgE-mediated sensitization to shrimp, cockroach, and dust mite in relation to allergen exposure in...

INTRODUCTION Cockroach allergen exposure elicits cockroach sensitization and poses an increased risk for asthma. However, the major components in cockroach allergen and the mechanisms underlying the induction of cockroach allergen-induced allergy and asthma remain largely elusive. We sought to examine the role of cockroach-associated glycan in regulating human basophil function. METHODS N-lin...

Asthma is a major public health concern. Cockroach allergen exposure and cockroach allergic sensitization could contribute to the higher prevalence of asthma. However, the underlying immune mechanism and the genetic etiology remain unclear. Recent advances have demonstrated that several receptors (PAR-2, TLRs, CLRs) and their pathways mediate antigen uptake from the environment and induce aller...

BACKGROUND Cockroach allergy is common among inner city children with asthma, and exposure to cockroach allergen is associated with more severe disease. However, there has been little evaluation of educational approaches for controlling cockroach infestations and reducing allergen exposure. OBJECTIVE An educational intervention to reduce cockroach allergen exposure in the homes of Hispanic ch...

PURPOSE Cockroach feces are known to be rich in IgE-reactive components. Various protease allergens were identified by proteomic analysis of German cockroach fecal extract in a previous study. In this study, we characterized a novel allergen, a chymotrypsin-like serine protease. METHODS A cDNA sequence homologous to chymotrypsin was obtained by analysis of German cockroach expressed sequence ...
