The parasites that normally cause fish disease under farming condition possess a direct life cycle with no need to intermediate hosts for dissemination. The ensuing infection can therefore spread rapidly inducing more damaging lesions in the external parts of host especially the gills. In this study, in order to isolate and identify foreign parasites of phytophagous fish in Guilan province, 4 f...
Background and Objectives: The subtilisin genes (SUBs) of Trichophyton rubrum play an important role in destroying the keratin to produce a nutritional source and virulence. This study was carried out to determine the presence of subtilisin genes in T. rubrum isolated from patients with dermatophytosis in Tehran in 2017. Materials and Methods: This descriptive study was performed on 32 pati...
abstract the current study set out to address the issue as to whether the implementation of portfolio assessment would give rise to iranian pre-intermediate efl learner autonomy. participants comprised 60 female in pre-intermediate level within the age range of 16-28.they were selected from among 90 language learners based on their scores on language proficiency test -key english test. then, t...
Previous studies demonstrated that CSE induces oxidative stress and its consequences on isolated mitochondria obtained from lung, heart and brain which may provide insight into the role of CSE in human health and disease. The present study was carried out to further characterize and compare toxic effect of CSE extract on isolated mitochondria obtained from either a directly contacting tissue (i...
A total of 180 fish samples from three commercially important teleosts (Epinephelus coioides, Euthynnus affinis and Thunnus tonggol fish) of Persian Gulf across Hormozgan coast were investigated for plerocercoid infestation, which were sampled from Jun 2017 to September 2017. The parasites were fixed, stained, mounted on to slides and identified. Epinephelus coioides was not infested. Following...
Background and purpose: Giardia cyst and trophozoite have invariant morphologies, therefore, investigating aspects such as host specificity, transmission patterns and clinical behavior of the parasite in hosts requires molecular characterization of the parasites isolated from clinical samples. The aim of this study was to characterize giardiasis isolated from human fecal samples with symptomati...
The aim of the present study was shedding light on disease factors underlying mortality event among common carps inhabiting Hirfanlı Dam Lake in Türkiye spring year 2021. For this purpose various parasitological, bacteriological and virological research techniques were employed. Five parasite genera, Dactylogyrus spp., Myxobolus Eimeria Trichodina Diplostomum spp. isolated from 13 carps. opport...
A total of 394 (255 males,139 females) live freshwater crayfish Astacus leptodactylus from four stations of Aras reservoir in West Azarbaijan Province (North-Western Iran) were studied during the winter until early autumn of 2009 for the presence of parasites, Epibionts and Fungal agents. Parasitological surveys were carried out on gills exoskeleton and internal organs, mycological examinations...
fungal infections of fish are widespread problem which affect wild and farmed species. the aim of the present study was to isolate and identify fungal flora in cultivated and natural caspian sea acipenser persicus. the samples were obtained from skin, fin and gill of the fish and were inoculated into culture media with antibiotics and incubated at 23±1 ?c. 13 species of fungi isolated from the ...
Some parasites can be transferred from fish to human via eating of contaminated meat and make serious problems in consumers. In the present study zoonotic parasites of abdominal cavity in pike-perch, Sander lucioperca, in south eastern part of the Caspian Sea have been surveyed. In this regard, 30 fish were caught by purse seine net and abdominal cavity, digestive tract and other organs (kidney...
