background : free-living amoebae such as acanthamoeba species may act as carriers of cryptosporidium and toxoplasma oocysts, thus, may play an important role in the water-borne transmission of these parasites. in the present study, a loop mediated isothermal amplification (lamp) method for detection of toxoplasma and a pcr assay were developed for investigation of acanthamoeba in environmental ...
INTRODUCTION While NTM infection is mainly acquired from environmental exposure, monitoring of environmental niches for NTM is not a routine practice. This study aimed to find the prevalence of environmental NTM in soil and water in four highly populated suburbs of Tehran, Iran. MATERIAL AND METHODS A total of 4014 samples from soil and water resources were collected and studied. Sediments of...
BACKGROUND The aim of this study was the seroepidemiological survey for detecting the status of human fasciolosis in Lorestan Province, western Iran. METHODS This cross-sectional study was conducted in 2015-16. Based on statistical estimations, 1256 serum samples were collected from different parts of Lorestan Province, western Iran, and stored at -20 °C until use. The collected serum samples...
BACKGROUND Free-living amoebae belonging to the genus Acanthamoeba have an environmental distribution. Amoebic keratitis due to these protozoan parasites continue to rise in Iran and worldwide. In Iran, there are various researches regarding both morphological and molecular identification of Acanthamoeba spp. in environmental and clinical samples. However, there is no thorough review about Acan...
This study is designed to determine the contamination degree of hospital water supplies with Pseudomonas aeruginosa, Legionella pneumophila, and E. coli in Gilan, Iran. Samples were collected directly into sterile containers and concentrated by centrifuge. Half part of any sample transferred to yeast extract broth and the second part transferred to Trypticase Soy Broth and incubated for 3 days....
PURPOSE The present study was designed to evaluate the occurrence of Legionella contamination in the tap water of Tabriz hospitals, Azerbaijan, Iran. METHODS One hundred and forty water samples from diverse water supply systems of 17 hospitals were collected and analyzed for the presence of Legionella spp. by PCR assay. RESULTS In this study, 10 of 140 (7.1%) samples were positive for Legio...
Enterohemorrhagic Escherichia coli (EHEC) of the O157:H7 serotype is a worldwide zoonotic pathogen responsible for the majority of severe cases of human EHEC disease. The aim of the present study was to investigate the prevalence of E. coli O157: H7/NM in raw meat samples from two provinces of Iran. During a period from March 2010 to March 2011. Two hundred and ninety five raw meat samples were...
The free living amoeba, Acanthamoeba spp are found and distributed in a wide variety of environmental sources including air, water, soil dust, vegetables as well as the skin, cornea, lung and brain of human (1). Isolation of Acanthamoeba cyst from environmental sources such as soil, fresh surface water and stagnant water have been showed that this environmental sources have potential importance...
Problem Statement Agricultural water management (AWM) is not a goal in itself but part of a process of resource management that provides a critical input to agricultural production and farmer incomes. Today, huge losses in irrigation systems and poor water management practices worsen the water crises that already exist. Water users were surveyed in order to explore their perception about the fa...
Background & Aims of the Study: Lack of access to safe drinking water can lead to undesirable aesthetic problems and adverse health effects such as infectious diseases. The aim of this study was to investigate the microbiological quality of the drinking water distribution network in Divandareh City (Kordestan-western Iran). Materials & Methods: This study was ...
