Course/Module description:
Microorganisms inhabiting arthropods influence the biology of their hosts. Effects which include changes in behavior, reproductive biology, resistance to environmental conditions and natural enemies, the immune system and the ability to transfer pathogens. During the course, we will examine different types of symbiosis between microorganisms and arthropods, and discuss the interaction between different microorganisms within the host, with emphasis on medical and agricultural implications of these interactions. In addition, we will learn about ways to use microorganism-host relations in programs for pest and disease control.
Course/Module aims:
Revealing the symbiotic relationships between microorganisms and arthropods and understanding their impact on the biology of the partners.
Learning outcomes - On successful completion of this module, students should be able to:
To implement and understand symbiotic relationship in various research themes.
Attendance requirements(%):
100
Teaching arrangement and method of instruction:
Lectures, Seminars
Course/Module Content:
Introduction: symbiosis-axis from mutualism to parasitism.
Pathogens transmitted by arthropods: transient symbionts.
From transient to persistent symbiont: Symbiont establishment in the host.
Obligatory symbionts: nutrition and survival.
Facultative symbionts: resistance, protection, and reproduction.
Modes of Transmission: different (and obscure) ways to inter-intra-generational transmission, and on evolutionary scale.
Genomes of endosymbiont: How low can you go?
"Super Symbiont" Wolbachia in arthropods and nematode.
Interactions between different microorganisms in hosts: symbiont based control.
