Human accidental infection with Angiostrongylus costaricensis may result in abdominal disease of varied severity. Slugs from the Veronicellidae family are the main intermediate hosts for this parasitic nematode of rodents. Phyllocaulis variegatus, Phyllocaulis soleiformis and Phyllocaulis boraceiensis were experimentally infected to describe the kinetics of L3 elimination in the mucus secretion...

Background: Following the expansion of human infertility, different procedures have been utilized for separation of normal sperm during ICSI (Intra cytoplasmic sperm injection). Hypo-osmotic swelling test (HOST) is one of the tests which have been introduced for assessment of integrity of sperm membrane when confronted with hypo osmotic condition. This test may also reflect intracellular organe...

Salmonella enterica and Escherichia coli are bacterial species that colonize different animal hosts with sub-types that can cause life-threatening infections in humans. Source attribution of zoonoses is an important goal for infection control as is identification of isolates in reservoir hosts that represent a threat to human health. In this study, host specificity and zoonotic potential were p...

The genus Ramularia includes important plant pathogens with worldwide distribution, commonly associated with leaf spot diseases on a broad range of plant hosts. Although these fungi are common in Iran, most of the species found to date have been identified on the basis of morphological characteristics, and DNA data are available for limited number of them. During our investigation of fungi asso...

ABSTRACT- Elm leaf beetle (ELB), Xanthoga leruca luteola (Muller), is considered as one of the most important and destructive phytophagous pests of Ulmus species in the north of Iran. In the current study, the effects of three host plants including Ulmus carpinifolia, U. carpinifolia var. umbraculifera, and Zelkova carpinifolia, on feeding indices and biochemical processes of ELB were examined ...

Background: During ICSI, motile sperm with normal morphology are selected and injected into oocyte. But integrity of chromatin is not observable. Therefore, researchers are trying for to present novel method of sperm selection with high percentage of normal chromatin. HOST test is a useful assay of functional integrity of the human sperm membrane. We decide to use HOST test after DGC for infert...
