The protozoan parasite Entamoeba histolytica is the causative agent of amebiasis in man. The trophozoite or motile form is a highly dynamic and pleomorphic cell with a great capacity to destroy tissues. Moreover, the parasite has the singular ability to phagocytize a variety of different live or death cells. Phagocytosis of red blood cells by E. histolytica trophozoites is a complex phenomenon related with amebic pathogenicity and nutrition.

Представлена информация об ущербе картофелеводству от дитиленхоза в последние годы. Описаны симптомы поражения картофеля клубневой картофельной нематодой, биология возбудителя, его устойчивость к факторам внешней среды. Детально представлены эпифитотиология дитиленхоза картофеля (вертикальный, хронологический, горизонтальный механизмы передачи и сохранения возбудителя), способы его диагностики, меры защиты в фермерских, крестьянских и личных хозяйствах.Information on the damage to potatoes from Ditylenchus destructor in recent years is presented. The symptoms of the potato lesion by Ditylenchus destructor, the biology of the pathogen, its resistance to environmental factors are described. Epiphytotiology (vertical, chronological, horizontal mechanisms for the transfer and preservation of the causative agent), methods of its diagnosis, protective measures at peasant and private farms are given in details.

Structural Aspects

In 2019, an outbreak occurred which resulted in a global pandemic. The causative agent of this serious global health threat was a coronavirus similar to the agent of SARS, referred to as SARS-CoV-2. In this work an analysis of the available structures of the SARS-CoV-2 main protease has been performed. From a data set of crystallographic structures the dynamics of the protease has been obtained. Furthermore, a comparative analysis of the structures of SARS-CoV-2 with those of the main protease of the coronavirus responsible of SARS (SARS-CoV) was carried out. The results of these studies suggest that, although main proteases of SARS-CoV and SARS-CoV-2 are similar at the backbone level, some plasticity at the substrate binding site can be observed. The consequences of these structural aspects on the search for effective inhibitors of these enzymes are discussed, with a focus on already known compounds. The results obtained show that compounds containing an oxirane ring could be considered as inhibitors of the main protease of SARS-CoV-2.
