BACKGROUND Regarding to the significant of the possibility of the malaria epidemic and nuisance of mosquitoes during the active season, the fauna and some ecological activities of mosquitoes in related to tree holes were investigated from April to December 2009 in Neka county of Mazandaran Province, northern Iran. METHODS Larval collection was carried out from natural, artificial breeding pla...

There is a direct relation between the prevalence of some parasitic diseases and the presence of those etiologic agents in water. The purpose of this research was to determine the contamination rate of wells drinking water to parasites in Mazandaran province in the north of Iran. 989 water samples were randomly taken based on the population of towns and number of health centers from 12 cities o...

increasing greenhouse gases in recent decades and increasing its resulting temperature has causes the imbalance of the earth’s climate system and widespread climate changes in most regions of earth planet. development strategic policy in this area has been forced with a big challenge because of the need for water in the central region on the one hand and water resource constraints on the other ...

Over the past few years, the syndrome of streptococcosis has been associated with outbreaks in rainbow trout (Oncorhynchus mykiss, Walbaum) and caused significant economic losses in the aquaculture industry in Iran. The main purpose of this work was molecular identification of some causative agents of streptococcosis in rainbow trout. A total of 520 samples were collected from the head kidney o...

The significance of uncertainty analysis (UA) to quantify reliability of model simulations is being recognized. Consequently, literature on parameter and predictive uncertainty assessment of water resources models has been rising. Applications dealing with urban drainage systems are, however, very limited. This study applies formal Bayesian approach for uncertainty analysis of a widely used sto...

background: toxoplasmosis in immunocompetent people is generally asympto­matic but in immunocompromised patients including hiv/aids, can­cer pa­tients, and organ transplant recipients, etc. it can lead to serious pathological problems. the objective of current study was to determine the seroprevalence of t. gondii igg and igm antibodies in hiv/aids patients using elisa technique in mazanda­ran ...
