In 30 urban apartments (Szczecin, Police, Pyrzyce and Łobez) and rural quarters (Przelewice, Brzesko Szczecińskie, Bylice, Krasne, Kakolewice, Wierzchowo, Przeradz, Kłodzino) from NW Poland, 150 samples of dust were collected at 5 locations: bed area, bedroom carpet, sitting area in the living room, hall carpet, and kitchen floor. Mites were isolated using Berlese-Tüllgren extractors. The isolated dust mites belonged to the order Astigmata, families Pyroglyphidae: Dermatophagoides farinae Hughes, 1961, Dermatophagoides pteronyssinus (Trouessart, 1987), Euroglyphus maynei (Cooreman, 1950) and Hirstia Hull, 1931; Chortoglyphidae: Chortoglyphus arcuatus (Troupeau, 1879) and Glycyphagidae: Gohieria fusca (Oudemans, 1902), Lepidoglyphus destructor (Schrank, 1781), and the order Prostigmata, family Cheyletidae: Cheyletus (Latreille, 1796). The most frequently observed were the species D. farinae (58.9%) and the representatives of the genus Cheyletus (30.6%). Statistically significant differences were found between: the number and concentration of D. farinae in the dust collected from beds in the bedroom and dust from the carpet in the bedroom, living room, hall and kitchen; the number of D. farinae in samples from the carpet in the bedroom and from the kitchen floor; the number and concentration of D. farinae in the dust from the living room and the dust in the hall and kitchen; the number of Cheyletus sp. in samples of dust from bed areas in the bedroom and the samples from the carpet in the bedroom, hall and kitchen; the number and concentration of Cheyletus sp. in dust samples collected from the carpet in the bedroom and samples from the kitchen; the concentration of Cheyletus sp. in dust collected from bed areas and samples from the floor in the hall and kitchen; the number of D. pteronyssinus in dust samples collected from bed areas in the bedroom and samples from the carpet in the bedroom. In conclusion, the number of mites D. farinae, D. pteronyssinus and Cheyletus sp. depended on the place where the mites were sampled. The greatest numbers of these species were observed in the bed areas in bedrooms. The tests confirmed the high occurrence of house dust mites in the apartments in north-western Poland, especially in the bed areas in the bedroom.</p>","PeriodicalId":23835,"journal":{"name":"Wiadomosci parazytologiczne","volume":"56 1","pages":"51-7"},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"28969378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"[The immune response to fungal infections].","authors":"Piotr Kurnatowski,&nbsp;Anna J Kurnatowska","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>In mycoses congenital--nonspecific innate as well as acquired immunity (involving neutrophiles, monocytes, macrophages, dendritic cells and lymphocytes) both play important roles in host defence. Th1 lymphocytes release cytokines (IL-2, IL-12, IFN gamma) and stimulate cytotoxic cells and neutrophiles to destroy fungal cells. Th2 lymphocytes, on the other hand, suppress cellular immunity by releasing the cytokines IL-4, IL-6 and IL-10 which counter regulate the secretion of IL-2, IL-12, IFN gamma and depress the activity of macrophages. Cellular mechanisms play essential roles in host responses to fungal infections. Dysfunction of T lymphocytes and a reduction in their number are typically observed in patients with mycotic diseases. There occurs a reduction of both T lymphocyte populations and the T-helper to T-suppressor cell number ratio, and these are of critical importance in explaining the diminished IgA production and enhanced adhesion of fungal cells to the surface of host cells as well as in facilitating the intrusion of fungi throughout the skin and mucous membranes. The specific immunological reaction, associated with the synthesis of antibodies against fungal cell wall or cytoplasmic antigens, is of little significance in protective immunity, but nevertheless has a rather important role to play in diagnosis as well as in supporting phagocytosis by inhibition of fungal cell adherence. In patients with mycoses, typically low blood serum level of the immunoglobulin class G and A and low sIgA in saliva are observed. A detailed understanding the nature and function of the immune system in mycoses is necessary to enable improvements in pharmacotherapy with antifungal antibiotics and chemotherapeutics, as well as to treatments based on immunotherapy and vaccination.</p>","PeriodicalId":23835,"journal":{"name":"Wiadomosci parazytologiczne","volume":"56 1","pages":"23-7"},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"28969375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the results of molecular biology techniques it is possible to distinguish them as well as many subspecies or strains. It is known since quite some time that there are substantial differences in vector specificity, cross-immunity and pathogenicity between isolates of this species. Also the results of molecular analysis of these protozoa indicate that their genetic structure is diversified. On the basis of analysis of Babesia DNA sequences, the new variants of protozoa in dogs were detected.

Three tests were used in this study; API 20 C and API 20 AUX tests were used to differentiate interspecies biochemical features, and identify the codes of individual strains, while the API ZYM test was used to evaluate extracellular hydrolase activity and compare their enzymograms. Strain biotyping was also conducted with the use of binomial distribution 1:4:6:4:1. Comparing the codes of strains from successive sections of the alimentary tract identified pentafocal, tetrafocal, trifocal and bifocal invasions. The analysis of the enzymograms from all strains allowed the diagnosis of trifocal and bifocal candidosis.
