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...
The model of predominant clonal evolution (PCE) proposed for micropathogens does not state that genetic exchange is totally absent, but rather, that it is too rare to break the prevalent PCE pattern. However, the actual impact of this "residual" genetic exchange should be evaluated. Multilocus Sequence Typing (MLST) is an excellent tool to explore the problem. Here, we compared online available...
AIM Prevalence and risk factors associated with intestinal parasites among children ≤ 12 years old in Nahavand county western Iran, was the objective of this search. BACKGROUND Intestinal parasites (IPs) are important health problems among most societies. METHODS This cross sectional study was carried out during 6 months from April to September 2014 in Nahavand County western Iran. Fecal sa...
Blastocystis horninis is a common human parasite which is probably transmitted through a cystic stagevia the oral-fecal route (Boreham and Stenzel, 1993). A number of publications have appeared on the morphology of the cyst at the ultrastructure level (Stenzel and Boreham, 199 1 ; Zaman et 01, 1993; Stenzel et 01, 1993) but so far its light microscopic appearance has not been adequately describ...
Blastocystis is a common protist isolated in humans and many animals. The parasite is a species complex composed of 19 subtypes, 9 of which have been found in humans. There are biological and molecular differences between Blastocystis subtypes although microscopy alone is unable to distinguish between these subtypes. Blastocystis isolates also display various morphological forms. Several of the...
INTRODUCTION Some studies suggest Blastocystis hominis is a potentially pathogenic protozoa. Blastocystis hominis contributed to anaemia in children aged 8-10 years old in one study. AIM To compare haematological indices in cases with blastocystis hominis infection with healthy controls. MATERIAL AND METHODS From 2001 to 2012, 97600 stool examinations were done in 4 university hospitals. Pa...
The activities of n-hexane, dichloromethane and methanol extracts from five anti-diarrheic Thai medicinal plants, Acacia catechu (Fabaceae) resin, Amaranthus spinosus (Amaranthaceae) whole plant, Brucea javanica (Simaroubaceae) seed, Piper longum (Piperaceae) fruit and Quercus infectoria (Fagaceae) nut gall were tested against the in vitro growth of fresh isolates of the intestinal protozoan pa...
Blastocystis is the most prevalent eukaryotic microbe colonizing the human gut, infecting approximately 1 billion individuals worldwide. Although Blastocystis has been linked to intestinal disorders, its pathogenicity remains controversial because most carriers are asymptomatic. Here, the genome sequence of Blastocystis subtype (ST) 1 is presented and compared to previously published sequences ...
BACKGROUND Intestinal parasitic infections are considered a serious public health problem and widely distributed worldwide, mainly in urban and rural environments of tropical and subtropical countries. Globally, soil-transmitted helminths and protozoa are the most common intestinal parasites. Blastocystis sp. is a highly prevalent suspected pathogenic protozoan, and considered an unusual protis...
