SUMMARY hydatic cyst is a serious disease of man. That cause by a worm called taenia echinocococus, the adult worm lives in small bowel of dog and other canine host. The dog is the usual definitive host of this parasite and is important for transmition of this disease. In this study a total of 283 stray dags Teheran country were investigated for the present of intestinal metazoan parasites. T...

Pathogens infecting mammalian cells have developed various strategies to suppress and evade their hosts’ defensive mechanisms. In this line, the intracellular bacteria that are able to survive and propagate within their host cells must have developed strategies to avert their host’s killing attitude. Studying the interface of host-pathogen confrontation can provide valuable information for defi...

conclusions the results of this work demonstrated that the subcellular distribution of pfdn1 was altered in the rabv-infected n2a cells and colocalized with the n protein of rabv in the nbl structures. results confocal microscopy showed that pfdn1 was colocalized with the n protein of rabv in the infected n2a cells and was mainly recruited to the characteristic negri-body-like (nbl) structures ...

linguatula serrata is one of the important zoonotic parasites. carnivores serve as definitive host. the larvae existed in mesenteric lymph nodes (mlns), liver, lungs, etc of intermediate herbivores. the definitive host becomes infected by ingesting viscera containing the infective nymphal stage. humans may be infected with linguatula either by ingestion of nymphs resulting in a condition called...

Abstract: Potato virus Y a type species of the genus potyvirus infects several crops in the family solanaceae. PVY isolated from field infected peppers was identified on the basis of host reaction, serological and molecular characterization. The result of ELISA, Immunoblot electrophoresis and Immuno Capture Reverse Transcription Polymerase Chain Reaction   (IC-RT-PCR) indicated that...

Abstract Background and Aims: Hop stunt viroid (HSVd, genus Hostuviroid, family Pospiviroidae) has a wide host range among trees and herbaceous plants. The objectives of this study were to compare biological and physical characteristics of three isolates of HSVd from mulberry, fig and citrus and search for other hosts of this viroid in Iran. Materials and Methods: Plant samples were col...
