Seroprevalence of toxocariasis in hypereosinophilic individuals in Ahwaz, south-western Iran

Eosinophilia in human peripheral blood is caused by different agents, including toxocariasis. The present study aimed to evaluate the prevalence of toxocariasis in hypereosinophilic individuals in the city of Ahwaz, located in south-western Iran, using enzyme-linked immunosorbent assay and Western blot techniques. Serum samples were examined from 100 individuals with peripheral blood eosinophilia and also from another 100 individuals without eosinophilia as the control group. In hypereosinophilic individuals seroprevalence antibodies against Toxocara were found in 19 (19%), of whom 12 (63.15%) were female and 7 (36.85%) were male. Positive sera were subsequently confirmed by Western blot. All of the observed bands ranged from 24 to 100?kDa. Antibodies against Toxocara were found in 1% of the control group, but were not confirmed by Western blot. The results showed significant differences between the frequency of infection within age and gender (P?相似文献   

A study of dermatophytosis in South West of Iran (Ahwaz)

Two hundred and seventy nine patients suspected of having fungal lesions were examined. Skin scrapping, hair samples and nail clippings were collected from patients. Direct and culture examinations were performed for all samples. About 115 cases of examined subjects had dermatophytosis. Dermatophytosis occurred mainly in adults males (20–29 years). Tinea cruris (24.3%) was the most common type of dermatophytosis followed by tinea pedis (16.5%), tinea corporis (14.8%), tinea ungium (13%), tinea capitis (11.3%), tinea faciei (11.3%), tinea manuum (7%) and tinea barbae (1.7%). Trichophyton mentagrophytes was the most prevalent species followed by Epidermophyton floccosum.     

Foraging population and territory estimates for Microcerotermes diversus (Isoptera: Termitidae) through mark-release-recapture in Ahwaz (Khouzestan, Iran)

Microcerotermes diversus Silvestri (Isoptera: Termitidae), an important pest in Ahwaz (Khouzestan, Iran), causes serious economic damage to wooden products in buildings. In this study, we determined the foraging populations and territories of this species using mark-release-recapture techniques. Based on both the weighted mean model and Lincoln index methods, mean termite foraging population estimates for two colonies, A and B, were 2,984,489 +/- 258,802 and 326,134 +/- 8,713, respectively. Estimates with the Lincoln index were 2,731,229 +/- 813,081 for colony A and 321,493 +/- 138,499 for colony B. Estimated horizontal foraging territories for colonies A and B were 25.59 and 44.16 m2, respectively. The maximum and minimum linear foraging distances were 5.40 and 2.14 m for colony A and 9.14 and 1.86 m for colony B, respectively. Our data expand the knowledge about the biology, ecology and behavior of M. diversus.     

Blood groups of Cakchiquel Indians from Sumpango, Guatemala

ABO, MN, Rh, P, Lutheran, Kell, Duffy and Kidd blood group systems were studied in a sample of 135 Cakchiquel-speaking Indians from Sumpango, Dpto. Sacatepequez, Guatemala. Sumpango represents an almost exclusively endogamous isolate in the western highlands some 42 km outside of Guatemala City. The bloods were collected by families, and tests on them are much more revealing than on unrelated individuals because the genotypes are so often evident, and genes that could not have been otherwise detected are revealed. What is lost in numbers of unrelated people is probably more than compensated for by the precision of gene identification. Some evidence of foreign genes in this Indian sample is afforded by gene B in a mother and three of her children, in a small frequency (0.01) of R^?2,?3 (cde or cDe), and perhaps in gene MU or Mu in a mother and son. Gene frequencies for the Sumpango sample are very similar to those of Matson and Swanson's ('63) Cakchiquel from nearby Chimaltenango and Patzicia. The Sumpango sample shows lower P and Jk^a and higher R^2,?3 (CDe), and of these the low P and high R^2,?3 stand outside of the known Maya range.
