Distinctive fungal communities in an obligate African ant-plant mutualism.
Three ant species nest obligately in the swollen-thorn domatia of the African ant-plant Vachellia (Acacia) drepanolobium, a model system for the study of ant-defence mutualisms and species coexistence. Here we report on the characteristic fungal communities generated by these ant species in their domatia. First, we describe behavioural differences between the ant species when presented with a c...
متن کاملEndosymbiont-Dependent Host Reproduction Maintains Bacterial-Fungal Mutualism
Bacterial endosymbionts play essential roles for many organisms, and thus specialized mechanisms have evolved during evolution that guarantee the persistence of the symbiosis during or after host reproduction. The rice seedling blight fungus Rhizopus microsporus represents a unique example of a mutualistic life form in which a fungus harbors endobacteria (Burkholderia sp.) for the production of...
متن کاملPloidy tug-of-war: Evolutionary and genetic environments influence the rate of ploidy drive in a human fungal pathogen.
Variation in baseline ploidy is seen throughout the tree of life, yet the factors that determine why one ploidy level is maintained over another remain poorly understood. Experimental evolution studies using asexual fungal microbes with manipulated ploidy levels intriguingly reveals a propensity to return to the historical baseline ploidy, a phenomenon that we term "ploidy drive." We evolved ha...
متن کاملFungal Keratitis Associated with Viral Keratitis
Microbial keratitis caused by more than one microorganism is rare. It may occur as a coinfection or as a secondary infection superimposed with an existent microorganism. [1] Both infectious and immune mechanisms are implicated in microbial keratitis. Herein, we report an unusual clinical case of viral and fungal mixed infection. Written informed consent was obtained from the patient. A 31‑year‑...
متن کاملBacterial, fungal, parasitic, and viral myositis.
Infectious myositis may be caused by a broad range of bacterial, fungal, parasitic, and viral agents. Infectious myositis is overall uncommon given the relative resistance of the musculature to infection. For example, inciting events, including trauma, surgery, or the presence of foreign bodies or devitalized tissue, are often present in cases of bacterial myositis. Bacterial causes are categor...
