Infection typically starts with fungemia before CNS involvement, with the capsule inhibiting host immune responses. Different species of Cryptococcus exhibit varying impacts, with C. neoformans causing vessel occlusion and C. gatti affecting immunocompetent individuals. Understanding the growth kinetics, antigenic properties, and host-fungus interactions is vital in elucidating the pathogenesis of fungal meningitis, emphasizing the need for early diagnosis and tailored treatment strategies.
What is the structural difference between firmicutes and other bacterial domains?
5 answers
Firmicutes exhibit distinct genomic features compared to other bacterial domains. They often display Purine Asymmetry (PAS), Strand-biased Gene Distribution (SGD), and contain the PolC isoform of DNA polymerase III alpha subunit. Additionally, Firmicutes are characterized by a dominance of specific bacterial Classes, such as Bacillales, Lactobacillales, and Clostridiales, which are linked to their physiology as lactic acid bacteria. In contrast, Actinobacteria possess a unique family of proteins, like the resuscitation-promoting factor (Rpf), which controls growth and resuscitation through muralytic enzymes, a feature not exclusive to Firmicutes. These differences in genomic characteristics and protein families highlight the structural distinctions between Firmicutes and other bacterial domains.
