background : zoonotic cutaneous leishmaniasis (zcl) is a neglected tropical disease prevailed in many rural areas of 17 out of 31 provinces in iran. the main vector of the disease is phlebotomus papatasi and the causative agent is leishmania major in zcl foci of iran. in the current study we investigated the validity of accessory glands secre­tions as an indicator to recognize parous from nulli...

introduction:  the use of radioactive iodine (131i) has become an important adjunct to the treatment of thyroid cancer and hyperthyroidism. salivary gland has the ability to concentrate radioactive iodine under normal circumstances. salivary gland dysfunction and dry mouth are the common side effectsof high-dose radioiodine therapy. the purposeof this study was to determine the absorbed dose of...

Definitive diagnosis of vesicular or vesicular-like lesions in livestock animals presents challenges both for veterinary clinicians and diagnostic laboratories. It is often impossible to diagnose the causative disease agent on a clinical basis alone and difficult to collect ample vesicular epithelium samples. Due to restrictions of time and sample size, once laboratory tests have ruled out foot...

RNA viruses possess the potential for rapid evolution and serve as excellent models to test evolutionary theory. Molecular phylogenetic analysis of the P gene for a larger number of diverse natural isolates of vesicular stomatitis virus reveals no evidence for a molecular clock but instead shows a stepwise evolutionary pattern unlike that ever seen before. Each step out from the tree's ancestra...

Culicoides biting midges serve as vectors of pathogens affecting humans and domestic animals. Culicoides sonorensis is a vector of several arboviruses in North American that cause substantial economic losses to the US livestock industry. Previous studies showed that C. sonorensis saliva, like the saliva of many hematophagous arthropods, contains numerous pharmacological agents that affect hemos...
