study on prevalence of gastrointestinal parasitic infections in HIV [+] patients referred to Ahvaz Razi Hospital in 2008-2009

Accute Immune Deficiency Syndrom [AIDS] is a serious and lethal disease in many parts of the world, rendering a patient sensitive to all opportunistic pathogens that can cause death as the disease progresses. Many patients suffer from intestinal opportunistic infections by parasites. The aim of present study was to examine parasitic intestinal infections in AIDS patients in Razi Hospital, Ahvaz. We collected 100 stool samples from 60 HIV [+] patients who were referred to Razi Hospital, Ahvaz. The samples were examined by direct and MIF [merthiolateiodine-formaldehyde] method. All samples were stained with Ziehl-Neelsen [acid fast staining] and trichrome. General data, such as clinical signs, duration of disease, route of infection, and habitat of patient, were obtained by questionnaire. Thirty percent of HIV [+] patients were infected with intestinal protozoan parasites. There was no significant difference in the prevalence of parasite infections between sex or age. The prevalence of parasitic infections was as follows: Blastocystis hominis, 16. 7%; Cryptosporidium parvum, 8. 3%; Endolimax nana, 5%; Entamoeba coli, 5%; Giardia intestinalis, 3. 3%; E. histolytica cyst, 1. 7%, and Dientamoeba fragilis, 1. 7%.This study shows that the prevalence of parasitic infections is not high in HIV [+] patient in Ahvaz compared with other studies, but it is recommended that fecal examination be performed every 3 months to detect serious parasitic infections and that parasitic infections should be treated after laboratory diagnosis and in the presence of the gastrointestinal symptoms.

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

Comparison of some electrolytes in hydatid cyst fluid and serum of liver hydatidosis of sheep

In this study, we collected 100 samples of liver hydatid cyst and blood of infected sheep from the Ahvaz abattoir. The existing Ca, P, Mg, Na and K were measured by an auto analyzer apparatus. The result of T. student test showed that there are a significant difference between serum and fluid of cyst in all electrolytes [p<0.05]. There was also a significant difference between these electrolytes in infected sheep and normal sheep [p<0.05]. These results confirmed that the entrance of essential electrolytes have depended on selective permeability and parasite requirement. Ca and P have vital roles in the prevention of hydatid cyst fluid acidity. Understanding parasite nutrition behavior would help us to conduct a better drug treatment in inoperative cyst via selection of effective drug and adherence of this drug to biological material that promote distribution of drug to the cyst

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
