BACKGROUND & OBJECTIVES To determine the possible role of cockroaches in dissemination of medically important microorganisms, a study was carried out in public hospitals and residential areas of Hamadan city, west of Iran. Bacteria, fungi and parasites of medical importance were isolated and identified. The total number of Blattella germanica collected from hospitals were 133 as the case group....

The use of attractive toxic sugar baits (ATSB) is a novelty in vector and residential pest control. This study aims to determine the concentration bait that able attract german cockroach Blattela germanica Linnaeus, effectiveness various types substances as an ATSB control cockroaches. method based on behavior adult insects eat sugars from sources contain materials will ultimately kill insects....

An allergen cloned from a Blattella germanica (German cockroach) cDNA library, encoded a 182-amino acid protein of 20,904 Da. This protein, designated B. germanica allergen 4 (Bla g 4), was expressed as a glutathione S-transferase fusion protein in Escherichia coli and purified by affinity chromatography and high-performance liquid chromatography. The prevalence of serum IgE antibody to recombi...

background : cockroaches are found as the most common urban pests of tropical countries, prompting economic and serious health risk problem for humans by carrying microbes and allergens, acting as vector for various patho­gens of diseases. the present study was conducted from april 2013 to march 2014 in various human dwelling local­ities of urban area of district lahore, pakistan. methods : coc...

OBJECTIVE To compare the prevalence of allergy to cockroaches (Blattella germanica and Periplaneta americana) in asthmatic and non-asthmatic children and to determine the degree of agreement between the skin prick test and serum specific IgE levels, as well as to establish the relationship between cockroach allergy and total IgE levels. METHODS A case-control study involving 76 asthmatic and ...

BACKGROUND microRNAs (miRNAs) have been reported as key regulators at post-transcriptional level in eukaryotic cells. In insects, most of the studies have focused in holometabolans while only recently two hemimetabolans (Locusta migratoria and Acyrthosiphon pisum) have had their miRNAs identified. Therefore, the study of the miRNAs of the evolutionarily basal hemimetabolan Blattella germanica m...
