Cryptograms, including ferns like Cryptogramma crispa and pathogens like Cryptococcus neoformans, reproduce through spores. Spores play a crucial role in the life cycle of cryptograms, acting as dispersal and resting phases for gametophytes. In the case of Cryptogramma crispa, spores are dispersed at the end of the growing season and undergo dormancy until the next spring, with germination occurring optimally at temperatures above 20°C. On the other hand, Cryptococcus species produce spores through sexual reproduction, which serve as infectious propagules, leading to pneumonia and meningitis in hosts. The spores of Cryptococcus neoformans can readily germinate and are fully virulent, contributing to the pathogen's survival and spread.Can manipulating the seminal microbiome improve fertility outcomes in men?

Manipulating the seminal microbiome shows promise in improving fertility outcomes in men. Studies have revealed that alterations in the seminal microbiota composition are associated with changes in semen quality and fertility status. Specific microbial taxa like Lactobacillus have been linked to improvements in semen parameters, while Prevotella has shown a negative impact on sperm quality. Furthermore, certain bacteria like Ureaplasma urealyticum, Enterococcus faecalis, and Mycoplasma hominis have been associated with decreased semen parameters, while Lactobacillus appears to protect sperm quality. These findings suggest that manipulating the seminal microbiome, potentially through probiotics, could be a novel therapeutic approach to enhance male fertility. However, further research with larger studies is needed to fully understand and validate the impact of such interventions on fertility outcomes.What is the title of the article written by M.A. Rahman in Chem.
