In this study a parasitological investigation on 238 samples of Neogobius species from the south-east of Caspian Sea was carried out. The samples including Neogobius melanostomus (35), N. fluviatilis pallasi (103), N. kessleri gorlap (70) and N. bathybius (30) were seasonally seined by beach net during one year (summer 2006-spring 2007), fixed in 10 % buffer formalinand transferred to the labor...

Studies on parasites infecting non-human primates are essential to better understand the potential threat to humans of zoonoses transmission, particularly under the current processes of pervasive land use change and biodiversity loss. The natural ecosystems in the Middle Magdalena river basin in Colombia have suffered a dramatic reduction and transformation into pastures and agroindustrial mono...

Abstract Host behaviour can be influenced by parasitic risk and infection through a variety of direct indirect mechanisms. We expect individuals expressing different phenotypes to also differ in the ways their is altered parasites. used land snail Cepaea nemoralis , species with various shell colour morphs differing physiology, as model study link between parasite response individual variation....

Human Immunodeficiency Virus (HIV) and intestinal parasitic infections are among the main health problems in developing countries like Ethiopia. Particularly, co-infections of these diseases would worsen the progression of HIV to Acquired Immunodeficiency Syndrome (AIDS). The purpose of this study was to determine the magnitude and risk factors for intestinal parasites in relation to HIV infect...

Purpose: To determine the prevalence of intestinal coccidian parasites in immunocompromised patients with or without diarrhoea at our centre. Materials and Methods: Stool samples were collected from 62 immunocompromised patients with diarrhoea and they were examined for the presence of coccidian parasites by microscopy. Also, 42 control samples from immunocompromised patients without diarrhoea ...

A study was conducted to determine the prevalence of intestinal parasites in children from eight schools located in Phuttamonthon District, Nakhon Prathom Province during November 2004 to December 2004. Stool samples were collected from 1920 students; age range from 7 to 12 years old, and examined for intestinal parasites by using formalin-ethyl acetate concentration technique. Of these subject...

Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder of uncertain etiology. Several studies have proposed the possible role of intestinal parasites in the pathogenesis of IBS. We aimed to summarize the epidemiological studies that describe a possible link between intestinal parasites and IBS, with special interest in endemic areas for intestinal parasitism such as South Amer...

Human immunodeficiency virus (HIV) seropositive patients usually suffer from opportunistic intestinal parasitic infections leading to high mortality & morbidity, knowledge about the etiological agents in HIV can often guide the treatment. The aim of this study was to identify the opportunistic parasites in HIV associated diarrhoeal and nondiarrhoeal patients and to study the importance of stool...

Background: Fruits and vegetables are potential vehicle of transmission of intestinal parasites. The main aim of this study was to determine prevalence of intestinal parasitic contamination in fruits and vegetables sampled from Caborca region, Northwest Mexico. Methods: A total of 400 fruit and vegetable samples were collected from unregulated open-air markets and closed (i.e., regulated) mark...
