Changes of Moraxella catarrhalis infection in children before and after the COVID-19 pandemic, Zhengzhou, China

Bacterial Proteases as Potentially Exploitable Modulators of SARS-CoV-2 Infection: Logic from the Literature, Informatics, and Inspiration from the Dog

“…It is, nonetheless, interesting to identify bacterial homologs to interesting proteases, such as HAT, A1AC, and PAI-1, within the proteomes of bacterial species classes that appear to exert influence on SAR-CoV-2 infectivity. These bacterial classes include both potential exacerbators of COVID-19 (e.g., Staphylococcus [173] and Pseudomonas [174,175]) and proposed mitigators (e.g., Dolosigranulum [173], Corynebacterium [173], and Moraxella [52,176]). Relevant proteases and antiproteases from these species families are reported in Table 1, according to homology (% identity) and alignment coverage (% coverage) relative to HAT, A1Ac, and PAI-1.…”

Changes of Klebsiella pneumoniae infection and carbapenem resistance in ICU elderly infected patients before and after the COVID-19 pandemic in Zhengzhou, China

“…Recent articles suggested that Streptococcus pneumonia (S. pneumoniae), Haemophilus influenzae (H. influenzae) and Moraxella catarrhalis (M. catarrhalis) infections among children in Zhengzhou, China showed a decreasing trend during the COVID-19 pandemic 1 , 2 , 3 . Previous studies also reported changes in carbapenemase-producing Enterobacteriaceae and extended-spectrum beta-lactamase (ESBL) E. coli infections during the COVID-19 pandemic 4 , 5 .…”
