Drug resistance in eukaryotic microorganisms

Chemosensory Transduction in Eukaryotic Microorganisms

Signal transduction is a topic that pervades the current literature, and well it should, since it encompasses studies from mitogenesis to synaptic transmis­ sion (1,19,124), Recent years have seen pieces of many cell and physiolog­ ical puzzles fall into place, and the pieces repeatedly are cell surface receptors (30, 130), G proteins (12, 13,49,63,82), second messengers (3, 6, 7, 78b, 90), and...

antimicrobial resistance in microorganisms

Malaria drug - resistance in Iran

Introduction: Malaria is a public health problem for approximately 2.4 billion people, 40% of the world’s population, particularly in the tropical and subtropical countries. Countries in Asia, and Latin America, the islands of the South, West, and central pacific ocean are all affected. Drug resistance is the greatest challenge in combating against malaria. Drug resistance in malaria is now w...

Searching for the role of protein phosphatases in eukaryotic microorganisms.

Preference for specific protein substrates together with differential sensitivity to activators and inhibitors has allowed classification of serine/threonine protein phosphatases (PPs) into four major types designated types 1, 2A, 2B and 2C (PP1, PP2A, PP2B and PP2C, respectively). Comparison of sequences within their catalytic domains has indicated that PP1, PP2A and PP2B are members of the sa...

Eukaryotic microorganisms in cold environments: examples from Pyrenean glaciers

Little is known about the viability of eukaryotic microorganisms preserved in icy regions. Here we report on the diversity of microbial eukaryotes in ice samples derived from four Pyrenean glaciers. The species composition of eukaryotic communities in these glaciers is unknown mostly because of the presence of a multi-year ice cap, and it is not clear whether they harbor the same populations. T...
