prospective study on the seasonal frequencies of insect bites [Diptera: Culicidae and Phlebotominae] and the related environmental and protective method factors in the city of Kashan, central of Iran, 2009

The current study was carried out in Kashan, central Iran, to find and interpret the factors which influence the mosquito and sand fly biting on human body. In this study five hundred residential houses were selected and checked out to determine the frequencies of mosquito and sand fly biting in the different regions of Kashan. Results of this study showed that 64.6% of the family residents, who took part in this study, were bitten by means of the insects [Culicidae and Phlebotominae insects] over one year. The Diptera insect biting [Culicidae and Phlebotominae] is a multi-factor activity. By knowing these factors we can make plan to reduce the insect population using different tools and methods which are discussed in this study

[Detection of intestinal parasite agents on raw consumed vegetables in Ahvaz]

The prevalence of parasitic disease is one of the major human hygienic problems in more countries especially in developing country such as Iran and it reached as high as 90% in some area of the world. The presence of parasitic disease has also observed in various rates in Iran .The important ways of parasite infection is oral route and raw consumption of vegetable. This research is a descriptive epidemiological study for evaluating vegetable contamination with parasitic agents. In this study, 40 samples of vegetable are collected from farms in four different geographical area around Ahvaz. The sedimentation method was used with anionic detergent as described by FAO method. In this study, nematode eggs 60%, larva of nematodes in the third stage 40%, intestinal protozoan 10%, have been seen. The abandonment of the use of human compost in agriculture Prevention of using of compost human in agriculture, hygienic washing of vegetable in endemic area and teaching principles of public health to people can control parasitic diseases and promote hygiene level of public health

Orbital Myiasis

To present a case of massive orbital myiasis. An 87-year-old debilitated woman suffering from left ocular pain of four days' duration presented with a severely necrotized left orbit and several attached live larvae. The upper and lower eyelids and the eyeball were completely destroyed. She had history of eyelid surgery in the same eye due to a skin lesion, apparently some type of skin cancer, 15 years before. The larvae were identified as Chrysomya bezziana [Diptera: Calliphoridae] or old world screwworm fly. Infestation of ocular and orbital tissues by fly larvae [ophthalmomyiasis] progresses rapidly and can completely destroy orbital tissues within days, especially in patients with poor general health. Treatment consists of removal of the larvae and surgical debridement

Study of scorpionism in Kashan in central Iran

The present research study was conducted to get new information due to the epidemiology of scorpionism in the region of Kshan, central of Iran. This was a descriptive retrospective study. Totally 230 files, belonging to the patients presented to the health centre and hospitals of city of Kashan during one year [March 22nd 2007 - March 21st 2008] were reviewed. In a questioner, this information was included and recorded for each patient: sex and age of scorpion sting victim, background of patient, antivenin treatment, month of scorpion sting, scorpion-stung part of body, color of scorpion and geographical place [rural/urban]. The frequencies of epidemiological parameters were converted to the percentage rank. The incidence of scorpion sting in Kashan is calculated as 58 persons in hundred thousand [100,000]. The results of this study show that the most of scorpion-stung patients were males [53.04%] and the rest were females [46.95%]. The distribution rate of ages shows that the greatest rate of scorpion stings were reported among the 15-24 year old people. Data collected in this study revealed that the highest incidence of scorpion sting cases took place in summer [75.7%] and the lowest in winter [0.4%]. Totally 73.91% of scorpion sting victims were from urban areas and the rest [26.08%] were from rural areas of Kashan. The scorpions brought to the Medical Centres by the patients or their relatives were identifiedas Odonthobuthusdoriae, Hotentta saulcyi, Compsobuthus sp., Androctonus crassicauda and Orthochirus sp. of Buthidae and Scorpio maurus of Scorpionidae in Kashan of Iran. It is concluded that the scorpionism in Kashan is similar to the other areas from the epidemiological cases including: distribution rate of ages, sex and site of stings. Existence of Hemiscorpius lepturus causes more clinical effects among people of south west of Iran than Kashan area

Identification of bacteria which possible transmitted by Musca domestica [Diptera: Muscidae] in the region of Ahvaz, SW Iran

The house-fly, Musca domestica L., not only is a nuisance pest, but also acts as an important mechanical vector for lots of pathogenic microorganism agents, including: bacteria, protozoa, worms, fungi and viruses amongst humans and animals. The aim of this study was to isolate and identification bacteria that are pick up by house-fly over the human and animal premises. In this study totally 230 houseflies were collected to isolate their bacteria, from the central slaughter house and a zoo in Ahvaz SW Iran. The most common isolated bacteria were Escherichia coli with 230 cases [36.5%]. The results of the current study confirm that flies are much more than a nuisance and that they pose potentially serious health risks. Consequently, the population of houseflies has to be controlled

Isolation Of fungi from housefly [Musca Domestica] in Ahwaz, Iran

The objective of this study was isolation of fungi on external surface of houseflies collected from Ahwaz, Iran. The fungal spores of the external surface of 275 house-flies [Musca domestica] were collected from Ahwaz, Iran. The flies were captured and rinsed in a solution of 1% sodium hypochlorite for three minutes and twice in sterile distilled water for 1min. The group of ten flies was transferred to a 0.85% saline solution. 0.1ml of this solution was transferred to Sabouraud's dextrose agar [SDA]. The plates were kept at room temperature to allow appearance of the fungal colonies. In this study 1295 fungal colonies were identified. The main fungi isolated were species of Aspergillus, Penicillium, Yeasts, Cladosporium and Fusarium. Also, 2 dermatophytes were recovered including Microsporum gypseum and Trichophyton mentagrophytes. Our study demonstrated that house-fly is a carrier for fungal spores

Two cases of chilopoda [centipede] biting in human from Ahwaz, Iran

These are the first known case reports of biting with centipedes in the two patients from Ahwaz, Iran. Erythema has been found in both female cases. Both patients complained of pain, itching and irritation following centipede biting. Haemoglobinuria and haematuria were seen in the both cases. Both patients were bitten by Scolopendra valid [Sclopendramorpha: Sclopendridae]
