conclusions according to the results of the present study, the prevalence of some infections with intestinal parasites is high in the hamadan city. considering that most of the parasites are nonpathogenic, pathogenic ones have been reduced generally in comparison to the previous reports. nevertheless, the existence of taenia species and h. nana could not be ignored. results among 228 samples, 8...

hydatid disease commonly involves liver but in rare cases, it can involve cardiac structures. a 75-yr-old farmer from parsabad-moghan, northwestern iran was presented to the emergency room of tehran imam khomeini hospital, tehran, iran with dyspnea and without chest pain in 2014. a lesion compatible with hydatid cyst was found in echocardiography and confirmed by serology and mri. surgical trea...

red foxes and golden jackals are the two most abundant wild carnivores of iran which have the ability to adopt a variety of habitats and human proximity. despite this, very few investigations on their helminth and none on their external parasites infections have been carried out in iran. between 2003 and 2004, a total of 79 jackals and 37 foxes were collected from 3 different climatic zones of ...

It is thought that allogrooming is practised strategically in order to establish, maintain and reinforce social bonds between group members, exchanging one altruistic behaviour for a different form of reciprocated benefit at a later date. Correlational evidence supports this, but evidence of causality is lacking. We reduced parasite loads in eight meerkat Suricata suricatta groups, generating a...

sturgeons are the most important fish in the caspian sea, but there are only a few reports on their parasite communities in the southern part of this sea. in this study, a total of 93 individuals of four sturgeon species, namely acipenser stellatus (n= 60), a.gueldenstaedtii (n = 12), a. nudiventris (n = 9) and huso huso (n = 12), were caught in 2 geographical regions from the southwest of the ...

the parasite fauna of 50 specimens of spiny eel obtained from two lakes, zarivar (in kurdistan province) and parishan (in fars province) and one river, heleh (booshehr province) were examined during the year 2003. a total of nine parasite species were found. gills of spiny eel were infected with ichthyophthirius multifiliis , trichodina pediculus (protozoa) and mastacembelocleidus heteranchorus...

intestinal parasitic infections are still a healthy problem in many developing countries, although intestinal parasitic infection has reduced in recent years, it is still prevalent in many regions of iran. this study was carried out in order to determine fauna and prevalence of human intestinal parasites in patients referred to kashan reference laboratory in 2007-2011. totally 6348 persons (53%...

background malnutrition and infections are widespread in almost all developing countries. the aim of this study was to investigating prevalence and some of the determinants of malnutrition and intestinal parasitic infections among preschool children in shahroud, iran. materials and methods at across-sectional study, the all preschool children (1,850 cases), in shahroud city as simple census, we...

The reduction in host fitness caused by parasite infections (virulence) depends on infection intensity and the degree of damage per parasite. Environmental conditions can shape both virulence components, but contrast to intensity, environmental impacts per-parasite are poorly understood. Here, we studied effect ambient temperature damage, which is jointly determined ability parasites induce har...

background: the prevalence and intensity of endo and ectoparasites in shrews inhabiting in the dasht-e razan of hamedan province, iran, were determined in this study. methods: by live traps, 64 shrews belong to species bicoloured white-toothed shrews ( crocidura leucodon ) were trapped during 2010-2012. captured animals were euthanized and their gender recorded. the blood thick and thin smears ...
