Seasonal morphological variations in bird schistosomes.

Penetration of Trichobilharzia cercariae into mammals: dangerous or negligible event?

Bird schistosomes and cases of human cercarial dermatitis occur worldwide, but the number of cases is not monitored. Experiments with two schistosomes, namely Trichobilharzia szidati and T. regenti, show that they possess potent tools to penetration bird and mammalian skin, as well as exhibit species-specific migration patterns within vertebrate bodies. Therefore, the infections may affect diff...

Evaluation of morphological variations of Iranian mandible condyles

Aims: The morphology of the condyle varies according to the race of the population in different places. Moreover, the identification of morphologies can be effective in diagnosing the pathogenesis and type of treatment of patients. Therefore, in this study, the researchers examine condyl morphology images using digital panoramic imaging. Materials and methods: This descriptive-analytical stud...

Determination and study the fatty acid contents and their seasonal variations by temperature of a dominant bivalve(Callista umbonella) of Haleh Creek

In this study fatty acid contents, because of the importance in human’s life, and their seasonal variations of a dominant bivalve of Haleh Creek were determined for the first time. Fatty acid identification was done by GC-MS (Gas Chromatography–Mass Spectrometry) method. After collecting and dissecting the species from the shells, samples weighed and frozen for further experiments. All the samp...

Schistosomes causing cercarial dermatitis: a mini-review of current trends in systematics and of host specificity and pathogenicity.

The human infection known under the names cercarial dermatitis or swimmers' itch is generally associated with swimming in lakes all over the world, however, a number of outbreaks of cercarial dermatitis developing in salt or brackish waters are also reported. The disease presents as allergic reaction which is able to trap and eliminate the parasites in the skin. However, the infection can be li...
