background: the global burden of sexually transmitted infections (stis) is noticeable and important. however, most stis are curable and all of them are preventable. in this article, we reviewed and evaluated sti prevalence, current services, existing programs, and the challenges of control and management them in iran. materials and methods: the author searched literature published from 2005 to ...

A vast majority of the burden from neglected tropical diseases result from helminth infections (nematodes and platyhelminthes). Parasitic helminthes infect over 2 billion, exerting a high collective burden that rivals high-mortality conditions such as AIDS or malaria, and cause devastation to crops and livestock. The challenges to improve control of parasitic helminth infections are multi-fold ...

Phosphoenolpyruvate carboxykinase (PEPCK) is present in parasites as well as in their mammalian hosts it serves different functions. In the host PEPCK catalyses the reaction from oxaloacetate to make phosphoenol pyruvate and carbon dioxide, part of the gluconeogenesis pathway. Parasite PEPCK catalyses the reverse reaction to form oxaloacetate, the precursor of malate, which is metabolized anaer...

Tuberculosis and intestinal parasites affect primarily low social and economic level populations, living clustered in precarious habitational settings. One of the interesting aspects of this interaction is the parasitism influence in cellular response to tuberculosis. In the present study, we evaluated the prevalence of enteroparasitosis in tuberculosis patients, HIV-infected and non HIV infect...

This study was conducted to find out the prevalence of intestinal parasitic infection among patients attending Nepal Medical College Teaching Hospital, Kathmandu from July 2011 to February 2012. A total of 312 stool samples collected in a clean, dry screw capped plastic container were examined using the formal-ether concentration and sucrose-flotation techniques. Overall parasite positivity rat...

BACKGROUND Fasciola hepatica is one of the most important helminthes parasites and triclabendazole (TCBZ) is routinely used for treatment of infected people and animals. Secreted protease enzymes by the F. hepatica plays a critical role in the invasion, migration, nutrition and the survival of parasite and are key targets for novel drugs and vaccines. The aim of study was to determine the prote...

Protozoa and helminthes can affect the lung as a primary site, or a complication. Some parasites have a migration cycle through the lung (larva migrans), inducing blood and tissue eosinophilia. Clinical manifestations of lung involvement could be acute: asthma –like syndrome, or Loeffler’s syndrome, with dyspnea, wheezing, cough; or chronic such as hemoptysis or right heart failure signs. Acute...

BACKGROUND Rodents have important role as reservoirs of different parasites. The aim of this study was to determine helminth parasites of abundant rodents in Meshkin-Shahr, Ardabil Province northwest Iran. METHODS From April 2014 to March 2015; 205 rodents including 118 Meriones persicus, 63 Mus musculus and 24 Cricetulus migratorius were collected, using live traps. All rodents were dissecte...

In this study the structure and diversity of the endohelminth community, as well as its interactions with 73 specimens of Piaractus mesopotamicus are described. The fish were caught in Aquidauana and Miranda rivers, both located in the Pantantal region, in the state of Mato Grosso do Sul. A total of 608,788 specimens of helminthes were found, representing five species: Dadaytrema oxycephala, Ch...
