ABSTRACT
Background: Given the importance of arthropods in medical and life sciences and information on the composition of such arthropods in this study was conducted during 2010 in the Kashan. Methods: Descriptive study and sampling at 13 locations and over 39 times in 2303 on the number of larvae, nymphs, Pupa and adults were collected from Lentic and Lotic waters. Samples collected after the transfer to the laboratory using a Stereo microscope and identified using morphological keys used were identified. Results: Total 2303 samples over 39 times the sampling of the Order Diptera, with 1,287 cases (55.8%), crustaceans, with 579 samples (25.2%), Order Trichoptera with 158 samples (6.9%), Order Ephemeroptera 153 samples (6.7%), Order Odonata with 61 samples (2.6%), Order Heteroptera with 26 samples (1.1%), Order Coleoptera with 26 samples (1.1%), Order Plecoptera with 13 sample (0.6) were identified. From Crustacea Class, three orders of the, Amphipoda to 405 numbers (70%) of Lotic water, Ostracoda to 144 (24.9%), Copepoda to 30 (5.1%) from the Lentic waters was collected. Conclusion: In This study, for the first time, from Crustacea subphyllum ,order of Ostracoda and Diptera order, Ceratopogonidae, Eryphidae, Dixidae families are reported .Therefore can be concluded that the aquatic arthropods Fauna Kashan is very rich. Considering that some of these insects have a role in the transmission or harassment of human and environmental balance are important, and with molecular methods is recommended that more specific studies done in this field.
ABSTRACT
Oral manifestations of HIV infection are common and include oral lesions and novel presentations of previously known opportunistic diseases. Some risk factors are significantly contributed to probability of developing opportunistic infection of oral candidiasis. We have performed the current survey to evaluate their role in Iranian patients with HIV infection. Totally, 377 documented HIV infected patients were included. Oral candidiasis was investigated with clinical observation, direct smear, and culture. Meanwhile, CD4 count was determined at the first visit and following antiretroviral therapy. The study population included 316 males and 60 females with a mean age of 36.5 +/- 8.7 years. Patients were diagnosed for a mean duration of 2.9 years. The most common route of infection transmission was shared needles [117 cases or 31%]. In serologic tests, 11 cases [2.9%] were positive for HBsAg, 206 cases [71.5%] for HCV nucleic acid and 53 cases [14.1%] for tuberculosis infection. At the first visit 52 cases [13.9%] and following HAART 31 cases [8.2%] were revealed to have oral candidiasis. Mean CD4 count in patients with oral candidiasis was significantly less than other patients [193.8 vs. 349.7 cells, P=0.0001]; however, the difference was not significant at follow up. Prompt diagnosis and treatment of HIV infection may have a significant role in prognosis and clinical course of patients with HIV infection and could decrease the rate of opportunistic infections
