The presence of Gram-negative bacteria in cuticle and alimentary tract of cockroaches collected from four selected areas of Dhaka city was investigated. Using detection key, a total of 12 cockroaches were identified as Periplaneta americana (58.33%), Blattella germanica (33.33%) and Blatta orientalis (8.33%). From these three species 54 different bacterial isolates were obtained. Out of them, 3...

Diflubenzuron (DIMILIN) is a powerful insecticidal chemical which has been known for many years to inhibit chitin synthesis in vivo in insects and related arthropod species. However, its action mechanism has remained unresolved partly because of its inaction on any of the enzymes involved in chitin synthesis in vitro. Based on our previous work (Diflubenzuron affects gamma-thioGTP stimulated Ca...

b a ckground: cockroaches are among the medically important pests found within the human habitations that cause serious public health problems. they may harbor a number of pathogenic bacteria on the external surface with anti- biotic resistance. hence, they are regarded as major microbial vectors. this study investigates the prevalence and antibiotic resistance of gram-negative pathogenic bacte...

Background: The serum glucose lowering, normalization animal body weight, and antioxidative stress effects of Mespilus germanica L. leaf extract were investigated in normal and streptozotocin-induced Balb/C mice. Methods: The phenol and flavonoid of the leaves of M. germanica were extracted by percolation and concentrated using a rotary evaporator. Its total phenol and flavonoid content was det...

PURPOSE The prevalence of allergic diseases is known to be associated with both demographic and environmental factors. Herein, we aimed to determine significant factors associated with the prevalence of allergic diseases and with total immunoglobulin E (tIgE) and specific immunoglobulin E (sIgE) levels in Korea. METHODS We analyzed unweighted data collected by the 2010 Korea National Health a...

The development of a novel repellent plays an important role in the integrated control of Blattella germanica. A series of novel hydronopylformamides derivatives were synthesized from a naturally occurring compound (-)-β-pinene. The structures of these hydronopylformamides derivatives were characterized by Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance spectroscopy (...

Endotoxins are common indoor biocontaminants. Their levels have been shown to link to many sources and factors. One of them is cockroach infestation but the role of cockroaches and contamination mechanisms are unclear. We hypothesized that not only is cockroach infestation a sign of poor hygiene, but it also contributes to indoor endotoxins via fecal contamination. In this study, different cock...

Development and activity of the corpora allata (CA) were investigated in adult female Blattella germanica and Supella longipalpa. These two cockroach species differ in their reproductive modes, with relatively uninterrupted cycles of oocyte development in S. longipalpa and discrete patterns of oocyte development which are interrupted by pregnancy in B. germmica. During ovarian cycles in both co...

This retrospective study reviewed skin prick test (SPT) positive results to various aeroallergens among 2136 children with allergic rhinitis (AR) in Guangzhou City, Southern China. Most (74.67%) of the 2136 children who underwent skin test showed positive reaction to 2-4 allergens. The allergen group with the highest positive incidence was Dermatophagoides pteronyssinus (der.p.) at 93.16%, foll...
