ABSTRACT
Background: Chlamydia trachomatis [CT], the most common bacterial sexually transmitted infection [STI], leads to pelvic inflammatory disease, infertility and chronic pelvic pain in women as well as an increased risk of vertical transmission, conjunctivitis and pneumonitis in infants. It may also be a co-factor along with human papillomavirus [HPV] in cervical cancer progression. We aimed to determine the prevalence of CT genotypes in genital specimens of women from South Khorasan, Iran and to test the association between CT and cytology statistics
Materials and Methods: This was a cross-sectional study on 248 Pap smear samples from women who visited a gynecologist for routine Pap smear testing in South Khorasan province. Nested polymerase chain reaction [PCR] was used to test the residual fluids of Pap smears for CT-DNA after cytological examination. Direct sequencing, alignment and phylogenic analyses were performed on eight samples to identify their genotypes
Results: The mean age of patients was 37.54 +/- 5.21 years. Most samples had a normal cytology [214 cases, 86.29%]. Overall, 31 samples were positive for CT infection [12.5%] of which 20 [9.34%] were normal and 11 [32.35%] were abnormal, with the frequency difference being significant [P=0.022]. The co-infection of CT/HPV in total was identified in 14 cases [5.6%]. The results of sequencing eight samples out of the 31 CT positive samples revealed the detection of genotypes D and E, each with four cases
Conclusion: We show that a high prevalence of genital CT infection is present in women with both normal and abnormal cytology; however, the higher prevalence among women in the abnormal group may indicate its involvement in cervical neoplasia
ABSTRACT
Leis mania is one of the most important diseases in Iran, with high prevalence in some part of country including, Tehran province this study was aimed to investigate the cutaneous lesions of patients studies was also referred to different 1aporatory of Health center of Vermin [a city In Tehran province], sand flies species m selected area. In this cross sectional study demographic data was collected by special questionnaire. Smears of suspected patients to stained and examined by microscope Sand flies were collected by sticky traps CDC light haps and aspirators, female specimens mere mounted and identified by diagnostic keys at species level Leis mania parasites were observed m 56 820 of cases. Disease was more common among male [64%] the majority of patients [3094] aged between 25-39 year old. Most lesions [50%] observed in hands and legs of patients, 76% of affected people had lust one lesion Half of them had a history of travel to endemic areas. More than 2500 sand flies captured during this study; among them 1100 female specimens were mounted and identified The prevalent spicies was Sergentomyia spp [65/9%], the second was papatasi [33/20%]. It should be mentioned that Ph sergenti, Ph alexandri and Ph caucasicus group also were identified in lower percentage According to current results and the status of the studied region including it seems that [Agricultural Activities animal husbandry and migration] cutaneous leishmaniasis could be a health threatening problem
ABSTRACT
Background and Aim: Free living amoebae [FLA] are amphizoic protozoa that are widely found in various environmental sources. They are known to cause serious infections in human and animal nervous systems. The aim of the current study was to determine the presence of Acanthamoeba spp in surface water sources in Birjand city employing microscopic culture analysis based on morphology features of the amoebae
Materials and Methods: In this cross-sectional study, 50 samples of surface water sources in Birjand city including parks pools, public squares, waterfronts, and water stations were collected and transferred to the laboratory and were passed through nitrocellulose filter paper. The remained elements in the filters were cultured on non-nutrient agar [NNA] with 100microl Escherichia coli suspension. After a few weeks of using morphological features, the amoeba grown were identified
Results: Out of the total of 50 samples cultured on non-nutrient agar [NNA], 19 [38%] samples were morphologically polluted with Acanthamoeba spp,. In 2 samples [4%] a colony of Vahlkampfiidae were observed
Conclusion: The results indicated that a significant percentage of surface water sources in Birjand city was contaminated with Acanthamoeba spp. It is necessary for physicians, therefore, to take into account the diseases caused by these infectious agents. Besides, local regional health professionals should take into consideration the potential role of surface stagnant water sources in transferring these infectious agents. Placing warning signs in areas contaminated with these infectious agents seems a useful measure
