Infection

Infection

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Skin Diseases and Disorders

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Diversity of Protists II

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Area of Science:

Mycology
Insect Pathology
Evolutionary Biology

Background:

Fungi are the primary insect pathogens, crucial in ecosystems and potential sources for pharmaceuticals and biopesticides.
Genera like Metarhizium exhibit genetic diversity and varied host ranges, making them excellent models for studying adaptation.
Comparative genomics reveals diverse fungal reproductive modes influencing genome evolution and pathogenicity.

Purpose of the Study:

To explore the genetic and genomic underpinnings of adaptive phenotypes in insect-pathogenic fungi.
To understand the evolutionary adaptations and pathogenic strategies of fungi infecting insects.
To highlight the potential of insect-pathogenic fungi in biotechnology and as biopesticides.

Main Methods:

Comparative genomics of entomopathogenic fungi.
Analysis of genetic diversity and intraspecific variation.
Investigation of fungal-insect interactions, including cuticle penetration and immune evasion.
Study of fungal manipulation of host behavior for transmission.

Main Results:

Entomopathogenic fungi display diverse reproductive strategies impacting genome evolution and pathogenicity.
Significant variations exist in host range and pathogenic mechanisms across fungal groups.
Fungi employ mechanical pressure and enzymes to breach insect cuticles and overcome host immune defenses.
Fungi exhibit complex behavioral manipulation of arthropod hosts to optimize transmission.

Conclusions:

Insect-pathogenic fungi are diverse and adaptable, offering valuable insights into evolutionary processes.
Their complex interactions with insects highlight their ecological importance and potential for novel applications.
Understanding fungal pathogenicity and host manipulation can lead to innovative biopesticides and biotechnological tools.
