The objective of the study was to identify bacterial flora from external parts of German cockroaches caught in hospitals. The susceptibility of the bacteria to the most important groups of antimicrobial agents was also examined. 80 strains of bacteria were isolated, among them 34 strains of Gram-positive cocci and 31 strains of Gram-negative rods. One of(More)
The prevalent synantropic species present in hospitals in Poland was the German cockroach (Blattella germanica L.), found in about 70% hospitals. It was followed by Oriental cockroach (Blatta orientais L.) and Pharaoh's ant (Monomorium pharaonis L.) occurred in 40% and 17% of hospitals respectively. Kitchens, laundries and lavatories were the most often(More)
UNLABELLED BACKGROUND. Mosquitoes are blood-sucking insects, nuisance to humans and animals. Their bites cause itching and allergic reactions. These insects are also vectors of several viruses, bacteria and parasites. Protection against mosquitoes is therefore justified and desirable. This can give repellents and products for protection small outdoor areas(More)
The resistance to four pyrethroid insecticides: permethrin, deltamethrin, cypermethrin, etofenprox, and to two carbamate insecticides--bendiocarb, propoxur was investigated on field strains of German cockroaches (Blatella germanica L.) caught in hospitals from various parts of Poland. The tests were carried out only on males by the contact method(More)
The evaluation of the infestation and methods of insect disease vectors control in 748 hospitals in Poland in the period of 1990 to 1995 were done. The insect species, places of their occurrence and control agents were analysed. Blattella germanica L. occurred most frequently (71% hospitals). Blatta orientalis and Monomorium pharaonis were found in 40% and(More)
Authors analysed changes in consumption of selected food groups (cereals, fruit, vegetables, meat, fat, sweets) as well as mortality indexes (CVD, intestinal cancers, diabetes) among four European countries (the Netherlands, United Kingdom, Norway, Sweden) during 1970-1992. It was shown that consumption of fruit and vegetables (except the Netherlands)(More)
After the flood in 2010 in many regions of Poland mosquitoes occurred in huge number and chemical control of them was performed. In Legionowo district the aerial application of deltamethrin-containing product was done. In the study the efficacy of the treatments was described. Mosquitoes were caught in CDC traps in five places located in the treated area(More)
The biological activity of baculovirus AcMNPV and its recombinant SPX were determined on cockroaches Blattella germanica, pharaoh's ants Monomorium pharaonis and flies Musca domestica--species very difficult to eradicate. Baculovirus AcMNPV is one of the best known viruses of wide host range. Its recombinant SPX contained the gene for natural toxin. It is(More)
