Female houseflies, Musca domestica (Diptera: Muscidae), lay their eggs in ephemeral resources such as animal manure. Hatching larvae compete for essential nutrients with fungi that also colonize such resources. Both the well-known antagonistic relationship between bacteria and fungi and the consistent presence of the bacterium Klebsiella oxytoca on housefly eggs led us to hypothesize (1) that K. oxytoca, and possibly other bacteria on housefly eggs, help curtail the growth of fungal resource… 

Ovipositing female house flies provision offspring larvae with bacterial food

E egg‐associated bacteria could be a fail‐safe mechanism that ensures a bacterial food supply for larval offspring, particularly if the resource selected by parent females is poor in bacterial food.

Semiochemical-Mediated Oviposition Avoidance by Female House Flies, Musca domestica, on Animal Feces Colonized with Harmful Fungi

It is concluded that fungus-derived volatiles serve as semiochemical cues that help house flies avoid resources colonized with fungal competitors for the development of larval offspring.

Saprophagous insect larvae, Drosophila melanogaster, profit from increased species richness in beneficial microbes

Not only yeast diversity had an effect on D. melanogaster life‐history traits, but also the identity of the yeast combinations, demonstrating the importance of the structure and diversity of microbial communities in mutualistic animal–microbe interactions.

Antibiotic-producing bacteria from stag beetle mycangia.

Bacteria present in the mycangia of stag beetles are useful resources for screening novel antibiotics, and it is suggested that Klebsiella spp.

Microbial communities of the house fly Musca domestica vary with geographical location and habitat

The results suggest that vectoring of a wide spectrum of environmental microbes occurs principally through the external fly body surface, while the internal microbiome is likely more limited by fly physiology.

Black Soldier Fly (Hermetia illucens) Larvae Significantly Change the Microbial Community in Chicken Manure

The treatment of chicken manure with H. illucens larvae significantly reduced the microbial diversity, while strongly increasing organic metabolism in the intestinal bacteria, showing the potential for applications in livestock manure treatment.

Relative contributions of egg-associated and substrate-associated microorganisms to black soldier fly larval performance and microbiota

Sub substrate-associated microorganisms impact not only larval microbiota but also larval performance, whereas egg- associated microorganisms have a minor role in the densities present.

Hawaiian Bobtail Squid Symbionts Inhibit Marine Bacteria via Production of Specialized Metabolites, Including New Bromoalterochromides BAC-D/D′

It is demonstrated that symbiotic bacteria from this gland can also inhibit other marine bacteria in vitro, and results indicate that BACs may provide Pseudoalteromonas sp.

In the beginning: egg–microbe interactions and consequences for animal hosts

Different functions of egg microbiomes are discussed and how these associations have influenced the biology and evolution of animal hosts are discussed.

Experimental evolution of defense against a competitive mold confers reduced sensitivity to fungal toxins but no increased resistance in Drosophila larvae

Antagonistic but non-pathogenic fungi favor insect variants better protected against the fungal chemical arsenal, highlighting the often proposed but experimentally underexplored importance of secondary metabolites in driving animal-fungus interactions.



Relationship between selected bacteria and the growth of immature house flies, Musca domestica, in an axenic test system.

It is illustrated that bacteria or their metabolic products are essential as nutrients for house fly maggot growth in blood agar; a wide variety of adventitious bacteria can contribute to the suitability of an organic substrate for maggot Growth; and a naturally occurring isolate of B. cereus limits house fly Magca domestica growth inBlood agar, a relationship that has not been reported previously.

Antagonism between Bacteria and Fungi on Decomposing Aquatic Plant Litter

It is suggested that the antagonism between bacteria and fungi is an important controlling factor for microbial colonization and growth on aquatic plant litter.

Persistence of Escherichia coli in Immature House Fly and Stable Fly (Diptera: Muscidae) in Relation to Larval Growth and Survival

It is suggested that house fly larvae digest E. coli and use it as a food source but stable fly larvae do not, and both species Survival of house fly and stableFly larvae averaged 62 and 25%, respectively, when reared on pureE.

Antimicrobial strategies in burying beetles breeding on carrion

It is concluded that parental care and carcass avoidance can function as antimicrobial strategies in this species, and the work of Janzen is generalized to include competition between microbes and insects that rely on carrion as an obligate resource for breeding and not just as an opportunistic meal.

Facultative bacterial symbionts in aphids confer resistance to parasitic wasps

Investigation of aphids for vulnerability of the aphid host to a hymenopteran parasitoid, Aphidius ervi, shows that infection confers resistance to parasitoids attack by causing high mortality of developing Parasitoid larvae.

Amphibian Chemical Defense: Antifungal Metabolites of the Microsymbiont Janthinobacterium lividum on the Salamander Plethodon cinereus

The hypothesis that cutaneous, mutualistic bacteria play a role in amphibian resistance to fungal disease is supported and exploitation of this biological process may provide long-term resistance to B. dendrobatidis.

Genetic Variation and the Role of Insect Life History Traits in the Ability of Drosophila Larvae to Develop in the Presence of a Competing Filamentous Fungus

The results of this study demonstrate the existence of genetic variation for larval developmental success in the presence of A. niger in a Drosophila population, and heritability of important insect life history traits differed as a function of the larval environment (fungal infected or uninfected feeding substrate).

Arbuscular mycorrhizal fungi can transfer substantial amounts of nitrogen to their host plant from organic material.

It is indicated that uptake from organic N could be important in AM symbiosis for both plant and fungal partners and that some AM fungi may acquire inorganic N from organic sources.

Euplotes magnicirratus (Ciliophora, Hypotrichia) depends on its bacterial endosymbiont 'Candidatus Devosia euplotis¹ for food digestion

The results indicate that this represents a new type of symbiosis between prokaryotes and ciliates, which is mutualistic, and most likely obligatory for both partners.
