Entamoeba histolytica is a protozoan parasite that causes amebic dysentery and liver abscess. The disease is common in tropical regions of the world where hygiene and sanitation is often approximate. The epidemiology of E. histolytica has been studied around the world. However, there is a dearth of comprehensive literature on the epidemiology of this pathogen as well as its pathogenicity in the...

the anamorphic fungus genus periconia is worldwide in distribution and causes foliar disease on plants mostly in tropical and subtropical regions. this study presents the description and illustration of p. palmivora discovered on leaves of phoenix dactylifera (palmae/arecaceae) from terai forest region of uttar pradesh, india. the taxonomic determination was based on morphological characteristi...

myiasis is the infection caused by a variety of dipterous (fly) larvae in vertebrate’s tissue (man and domestic or wild animals). species of gasterophilus are obligate parasite of horses, donkeys, zebras, elephants and rhinoceroses. there are records worldwide, but mostly, in tropical and subtropical regions. this case report describes a type of gastric myiasis caused by g. intestinalis in an o...

a chronic fungal infection in tropical regions, chromoblastomycosis is caused by dematiaceous fungi, the form-family of fungi imperfecti, usually affecting one lower limb at the site of a trauma but sometimes involving other areas of the body including head & neck. in this article, we report the case of a rare primary chromoblastomycosis of the palate and chest in a 27-year-old man who was succ...

introduction ophthalmomyiasis is a rare disorder that is caused by invasion of dipterous larvae to necrotic tissues. case presentation an 80-year-old woman with invasive basal cell carcinoma (bcc) presented anabnormal growth of worm in her eye. she had ophthalmomyiasis caused by lucilia sericata larva in here nucleated eye. l. sericata is common all over the temperate and tropical regions, main...

the anamorphic fungus genus periconia is word wide in distribution and causes foliar disease on plants mostly in tropical and subtropical regions. this paper presented the description and illustrations of p. palmivora discovered on leaves of phoenix dactylifera (palmae/arecaceae) from terai forest region of uttar pradesh, india. the taxonomic determination was based on morphological characteris...

Fruit flies evolved in tropical regions under stable light-dark cycles. However, their photosensitive circadian clock had to adapt to extreme seasonal photoperiods during their colonisation of temperate regions. This was achieved by changing the neuronal expression of two key clock-related components.

AIM: To investigate the allelic and haplotypic association of reg1α gene with tropical calcific pancreatitis (TCP). Since TCP is known to have a variable genetic basis, we investigated the interaction between mutations in the susceptibility genes, SPINK1 and CTSB with reg1α polymorphisms. METHODS: We analyzed the polymorphisms in the reg1α gene by sequencing the gene including its promoter regi...

Ocean warming is already affecting global fisheries with an increasing dominance of catches of warmer water species at higher latitudes and lower catches of tropical and subtropical species in the tropics. Tuna distributions are highly conditioned by sea temperature, for this reason and their worldwide distribution, their populations may be a good indicator of the effect of climate change on gl...

Despite the large implications of the use of tropical land for exports ("land absorption") on ecosystem services (ES) and global biodiversity conservation, the magnitude of these externalities is not known. We quantify the net value of ES lost in tropical countries as a result of cropland, forestland and pastureland absorption for exports after deducting ES gains through imports ("land displace...
