Cooperation and life history evolution help obligate parasites to circumvent host genetic deficiencies.

Published: April 2020

How do obligate parasites cope with hosts that lack genetic elements required for parasite replication? Gupta et. al. (2020) illustrate an experimental evolution system where lambda bacteriophages circumvent a defective gene network in their E. coli host (which initially made it impossible for them to replicate) through both intracellular cooperation and evolutionary changes in phage life-history traits.

Purpose: Encephalitozoon intestinalis is an obligate intracellular microsporidian fungus that causes severe gastrointestinal infections, particularly in immunocompromised individuals. Propolis (PROP), a resinous substance derived from bees, has antimicrobial, anti-inflammatory and antioxidant properties, while royal jelly (RJ) has immunomodulatory, antioxidant and antimicrobial activities. The aim of this study was to investigate the therapeutic potential of PROP and RJ against E.

is a Gram-negative, obligate aerobic bacillus commonly found in environmental settings, particularly in soil and water, as well as within the intestinal microbiota of humans and various animal species. This bacterium has the potential to act as an opportunistic pathogen, capable of causing severe infections in both humans and animals, which can sometimes result in fatal outcomes. Notably, is often characterized by a high degree of antibiotic resistance, complicating treatment efforts.

Toxoplasma gondii, an obligate intracellular protozoan, infects almost all warm-blooded animals and humans, with felines serving as its sole definitive hosts. Cats release T. gondii oocysts into the environment through feces, contributing to environmental contamination that can lead to toxoplasmosis in humans upon exposure through ingestion of contaminated food, water, or soil.

Background: Japanese encephalitis (JE) induced by Japanese encephalitis virus (JEV) infection is the most prevalent diagnosed epidemic viral encephalitis globally. The underlying pathological mechanisms remain largely unknown. Given that viruses are obligate intracellular parasites, cellular metabolic reprogramming triggered by viral infection is intricately related to the establishment of infection and progression of disease.

As obligate parasites, viruses exploit host cell organelles and molecular components to complete their life cycle. Among which, viruses firstly hijack the cytoskeleton of host cells to ensure their efficiently cell entry and replication. Although formin family members play a key role in both microfilament and microtubule cytoskeletal remodeling, few studies addressed the detailed function and mechanism of formins in the process of viral infection.
