ABSTRACT
The aim of this study was to conduct a sero-epidemiological survey in Meshkinshahr, Ardabil Province, northwestern Iran to detect the rate of hydatidosis in the city and nearby villages. Literature shows that no such study has been conducted so far. Overall, 670 serum samples were collected from 194 males and 476 females from patients referred to different health centers of the region. All patients filled out a questionnaire and an informed consent. Sera were analyzed using indirect-ELISA test. Ten micro g/ml antigens [Antigen B derived from hydatid cyst fluid], serum dilutions of 1:500 and conjugate anti-human cocombs with 1:100000 dilutions were utilized to perform the test. Data analysis was conducted using SPSS software ver. 11.5. The seroprevalence of human hydatidosis was 1.79% by ELISA test in the region. This rate for females was 1.68% and males 2.6%, respectively. There was no significant difference as regards all factors studied and the seropositivity. According to job, farmers and ranchmen had the highest rate of infection as 3.17%. The sero-prevalence of infection was 2.6%, respectively. There was no significant difference as regards all factors studied and the seropositivity. According to job, farmers and ranchmen had the highest rate of infection as 3.17%. The sero-prevalence of infection was 2.6% in illiterate people which showed the highest rate. As regards residency, urban life showed no significant difference with rural life [1.1% vs. 2.58%]. Age group of 69-90 yr old, with 4.62 as prevalence had the highest rate of positivity. Obtained sero-prevalence of hydatidosis shows more or less a resemblance to other cities of Iran, although due to the specific condition of the city we expected more rate of sero-positivity
ABSTRACT
Genus Trichostrongylus [Nematoda: Trichostrongylidae] is one of the most important zoonotic nematodes with wide geographic distribution in the world. The purpose of the present study was to describe morphological and morphometrical characteristics of male Trichostrongylus species, currently prevalent in domestic ruminants of Khuzestan Province, southwest Iran. Gastro-inetstinal organs of 1600 sheep, goats, cattle, and buffalos, slaughtered in Khuzestan Province, southwest Iran, were examined for infectivity with Trichostrongylus species. For examination and measurements of helminthes, Azo-carmine staining was performed, followed by camera lucida drawings of morphological characters and measurements of morphometrical criteria with a calibrated microscope. Using valid nematodes systematic keys, almost all the parasites were identified at the level of species. Overall, 114 animals were found infected with at least one species of Trichostrongylus. Considering morphlogifcal characteristics of male Trichostrongylus, six species were identified including T. colubriformis, T. vitrinus, T. probolorus, T. capricola, T. longispicularis and Trichostrongylus sp.. Although, compared to the previous decades, currently Trichostrongylus is much less prevalent in the domestic ruminants of the study area, but still different species occur in these animals
ABSTRACT
Background: a total of 76 rats including 4 black rat [Rattus rattus] and 72 brown rat [Rattus norvegicus] were captured from Kouzestan Province, Southern Iran
Materials and Methods: in the study area Dung beetles were prevalent and residents were complaining about. These arthropods act as intermediate hosts for Gongylonema species, and may cause infectivity in animaly, such as mose, rabbit, cat, cattle, and even accidentally humans
Results: in this study, the eosophagus and stomatch of rats were examined microscopically and three species of Gongylonema including G.pulchrum, G.neoplasticum, and G.monigy were found and their morphological charactery were described
Conclusions: the occurrence of these nematodes in rats is health treatening for human and domestic animals
ABSTRACT
Intestinal parasitosis has been a major public health problem in Iran. It is necessary to evaluate an up-date data in this regard to be used by local authorities. Serum IgE determinations and coproparasitological analyses were conducted on 1200 individuals in city of Ghaemshahr, Mazandaran province, northern Iran. A total of 1200 subjects were taken stool samples for three days consecutively. Two hundred and ninety seven cases [24.7%0] were positive for parasitic diseases. The age group of 8-15 years old encompassed the highest rate of infection which showed a significant difference with the other groups [P< 0.01]. No significant difference was detected between males and females as to the rate of infection based on the Chi-squared test [14.2% vs. 10.6%], but a significant difference was seen between infection rate and cases education [P<0.01]. An about 5-fold elevation in serum IgE level was demonstrated. Intervention programs including health education and environmental sanitation are recommended
