Cockroach extracts and whole bodies
We deliver whole bodies and extracts of the following domestic cockroaches: German cockroach (Blattella germanica), American cockroach (Periplaneta americana), and Oriental cockroach (Blatta orientalis). The whole bodies and extracts are used by researchers for allergen research. Our products will be delivered with a certificate of analysis including a SDS-page (CBB and Silver stain) and protein content (based on Bradford and BCA). Our products are produced accordingly high standards and are being used by multiple researchers and diagnostic companies worldwide.
Important for your research is to have cockroaches which don’t contain other products which may cause allergy such as peanuts or other food. Often, cockroaches are fed with peanut butter. Food like peanut butter and other allergens might interfere with your research. That is why we only use cockroaches which are fed with non-allergic food. With our extracts and whole bodies you are assured of a product with an absolute low of other allergens. In our controlled production we will make sure that we work conform protocols and that all of the information is well documented.
Out of all the species there are only five cockroaches which commonly inhabit homes and have the potential to induce respiratory allergies. These 5 species are Blattella germanica, Blatta orientalis, Periplaneta americana, Supella longipalpis and Periplaneta fuliginosa. Sensitisation to these species in asthma patients varies between 30-60% worldwide.
Cockroach aeroallergen particles have properties similar to those of mite allergens: they are relatively large (>10 µm in diameter), are detectable mainly after disturbance, and fall to the ground and settle rapidly. Patients are usually not aware of being allergic to cockroaches and do not report symptoms of asthma on entering a house that is infested with them.
Cockroach allergens are derived from several sources, such as saliva, fecal material, secretions, cast skins, debris, and dead bodies. Significant amounts of allergen can be recovered from cockroach washings and from the secretory debris called frass that accumulates in jars where cockroaches are kept in the laboratory. We have allergens from B. germanica, B. orientalis and P. americana available as whole bodies and extracts.
Cockroaches can be found worldwide
Cockroach infestations have been indicated as a major contributor to asthma throughout the world. Several studies have shown that large numbers of asthmatic patients are sensitized to cockroach allergens. There are about 3500 different cockroach species described and they can be found worldwide. Ten percent of properties in the world are estimated to be infested.
Although cockroaches are found throughout the world, the American, brown-banded, and Oriental cockroaches tend to predominate in tropical and subtropical regions. Cockroaches are an important cause of asthma in many regions of the world, including USA, Taiwan, Japan, Thailand, and Singapore in the Pacific Rim; Costa Rica and Puerto Rico in Central America; India; South Africa; and, more recently, Europe.
Blattella germanica cockroach
Blattella germanica, also known as the german cockroach, belongs to the Blattellidae family. B. germanica are the most widely spread urban pest. They life in all parts of the world, making the B. germanica a real cosmopolitan. The only threat for B. germanica are cold temperatures, therefore they mostly live indoor. The Blattella germanica contains, just like mites, allergens. These allergens are identified as one of the major indoor allergens inducing respiratory allergies. We can deliver B. germanica as an extract or as whole bodies. The German cockroach is about 16 mm in length and brown in color, with 2 dark longitudinal streaks on the protonotum. The female is slightly darker brown, with a broader rounded posterior.
Blatta orientalis cockroach
The Oriental cockroach is 25 mm in length and is dark brown to black, hence the common name black beetle. The male has rudimentary wings, but neither the male nor female can fly. Oriental cockroaches, often called water bugs, prefer dark, damp, and cool areas like basements and areas around sinks, drains, and washing machines. Usually they are found near garbage, sewage, or decaying organic matter. Very rarely are they found in high cupboards, on walls, or on the upper floors of buildings. Oriental cockroaches can tolerate cool weather, and outdoors they can be found under garbage cans, mulch, leaf brush, and other sheltered, damp areas. Oriental cockroaches produce allergens on their bodies and in their feces, and they may be a potential cause of childhood asthma and allergic dermatitis. The Oriental cockroach tend to predominate in tropical and subtropical regions.
Periplaneta americana cockroach
The American cockroach is a large cockroach, 38 mm in length, with fully developed reddish brown wings; it flies short distances. It is the largest of the common peridomestic cockroaches. Indoors, they are found in warm areas with high humidity — boiler rooms, basements, sewers or around drains and pipes. They are more common in large commercial buildings, infesting food-storage and preparation areas. The American cockroach has spread throughout the world by commerce. The American cockroach is rarely found in houses, however infestations can occur after heavy rain.
