RESUMO
Background:Although all the advances of medical science has come to achieve, parasitic infections including intestinal parasites in many countries especially in developing countries, is a health problem; according to the annual fees paid by that the World Health Organization and governments to eliminate, prevent and treat them, their existence is still visible. In this study the prevalence of intestinal parasite in mental disability community in Ardabil city will be studied
Material and methods: This descriptive cross-sectional study with was design to detect the prevalence of intestinal parasites on the 216 cases of mental disability under the Social Welfare Organization in Ardabil city, with methods of direct smear, formalin ether concentration method and Modified ziehl-neelsen staining
Results:_From 216 patients 95 samples [44%] were infected with at least one parasite including Blastocystis hominis 41 cases [19%], Entamoeba coli cyst 25 cases [11.6%], Giardia cyst 18 cases [8.3%], Trichuris trichura egg 2 cases [0.9%] and contemporary infection with two parasite Entamoeba coli / Blastocystis hominis cysts and_ Entamoeba coli / Iodamoeba butschili cysts 4 [1.9%] and 3 [1.4%] cases respectively. In 0.5% of cases we found Entamoeba coli cyst with 4 nuclei cysts
Conclusion:_According to the results, levels of intestinal parasitic infections in mental disability community in the Ardabil city in compare to other communities was higher that need to pay more attention of the authorities
RESUMO
Background and Purpose: Among Bacilli, Bacillus cereus, Bacillus thuringiensis and Bacillus anthracis are important and the latter causes anthrax. Toxin production in this bacillus is carried out by pxo1 gene and associated plasmid. Research has recently shown that this gene can transfer to other bacilli too. The present study was conducted to determine the frequency of pxo1 gene in bacilli other than Bacillus anthracis, so that they can be safely used in producing vaccines against anthrax
Methods and Materials: In this cross-sectional descriptive analytical study, 65 soil samples were collected from different geographical regions in Iran, and the organisms were isolated from the soil. Proteins isolated from bacilli were examined by SDS-PAGE technique, and the limits of coded proteins by pxo1 gene were specifically located. The data were summarized in Excel using figures and tables
Results: Based on the results, 13 out of 38 bacilli showed protein bands in the proteins coded by pxo1 gene, and all were from cereus family
Conclusion: In Iran, pxo1 plasmid has transferred from Bacillus anthracis to 13 bacilli isolated from Bacillus cereus
RESUMO
Background and Purpose: Vulvovaginal candidiasis is one of the most common infections in women and is caused by various types of candidiasis with different patterns of resistance against drugs. The present study was conducted to determine the various species of candidiasis in women admitted to Mobini Hospital in Sabzevar, Iran in order to make preventive recommendations for medical doctors
Methods and Materials: This cross-sectional descriptive analytical research was conducted on 231 women admitted to Mobini Hospital in Sabzevar, Iran, complaining of vaginal secretions. After getting the ethics committee permissions and obtaining the informed consent of the participants, at the same time as measuring vaginal pH, two swaps were used for collecting samples of secretions from lateral and posterior fornix. They were examined for yeasts and were then cultured in saburu dextrose. Grown yeasts were detected based on their macroscopic and microscopic features, tubulation in blood serum and biochemical characteristics using Yeast Plus System. The obtained data were analyzed in SPSS 11 using chi-square and bi-dimensional tables
Results: Positives results in direct examination results were 7.35%, and in culture the positive results were 26.8%. In detecting processes, candida albicans yeast [38.7%], Candida kefyr [17.7%], Saccharomyces cerevisiae [14,5%]; candia tropicalis [9.6%], Candida glabrata [8%], candida cruse [3.2%] were isolated with other non-pathogenic yeasts including Candida rugosa, Candida lipolytica, trycospron bejli, Blastoschizomyces capitatus [6.4%]
Conclusion: Non-pathogenic yeasts were isolated from patients with defective immunity systems, and need to be considered in patients with vaginal infections
