Can Insects Develop Resistance to Insect Pathogenic Fungi?

This paper presents new, important information on the microevolution of insect resistance to the insect pathogenic fungus Beauveria bassiana which will have far-reaching implications for the development of insect pathogenic fungi as biological control agents. We placed successive generations of a melanic population of the Greater wax moth, Galleria mellonella, under constant selective pressure from the insect pathogenic fungus, Beauveria bassiana. Enhanced fungal resistance was observed and larvae from the 25th generation were studied in detail to uncover mechanisms underpinning resistance, and the possible cost of those survival strategies. There are 3 novel, core findings from the study:1.Antifungal resistance in these insects is pathogen species-specific, and probably arises through trans-generational immune priming. The resistance was less obvious in earlier generations, suggesting subtle cumulative changes that are only fully apparent in the 25th generation. 2.The insect’s fecundity is already pushed close to minimum by its melanic phenotype. Therefore, the additional drain on resources required to boost antifungal defence still more, comes not from further compromising life history traits but via a re-allocation of the insect’s immune defences. Specifically during B. bassiana infection, systemic (fat body and hemocoel) responses, particularly the expression of antimicrobial peptides, are damped down in favour of a tailored repertoire of enhanced responses in the integument (cuticle and epidermis) – the foremost and most important barrier to natural fungal infection. 3.A previously-overlooked range of putative stress-management factors are activated during the specific response of selected insects to B. bassiana. This too occurs primarily in the integument, and contributes to antifungal defense and/or helps ameliorate the damage inflicted by the fungus or the host’s own immune responses during the battle between host and pathogen.No other study to date has examined so many genes in this context. Indeed, we show that the epidermis has a great capacity to express defense and stress-management genes as well as the fat body (which is the main tissue producing antimicrobial peptides and has been the traditional focus of attention). We therefore propose a “be specific / fight locally / de-stress” model to explain resource allocation and defence priorities for insects selected for superior resistance to insect-pathogenic fungi. However, we also show that these insects are less fecund and probably at no evolutionary advantage in the wild, implying that the risk is small of biological control agents failing in the field

A Narrative Review on the Pathophysiology and Management for Radiation Cystitis

Radiation cystitis is a recognised complication of pelvic radiotherapy. Incidence of radiation cystitis ranges from 23 to 80% and the incidence of severe haematuria ranges from 5 to 8%. High quality data on management strategies for radiation cystitis is sparse. Treatment modalities are subclassified into systemic therapies, intravesical therapies, and hyperbaric oxygen and interventional procedures. Short-term cure rates range from 76 to 95% for hyperbaric oxygen therapy and interventional procedures. Adverse effects of these treatment strategies are acceptable. Ultimately, most patients require multimodal treatment for curative purposes. Large randomised trials exploring emergent management strategies are required in order to strengthen evidence-based treatment strategies. Urologists encounter radiation cystitis commonly and should be familiar with diagnostic modalities and treatment strategies
