Based on the information available, there have been reports of increasing tigecycline resistance in bacteria. However, there is no specific mention of newly discovered bacteria with increased tigecycline resistance.

Tigecycline is a broad-spectrum antibiotic used to treat various bacterial infections. However, the increasing resistance to this antibiotic is a growing concern. A study published in the Journal of Global Antimicrobial Resistance reported an increasing trend of tigecycline resistance in Acinetobacter baumannii, Klebsiella pneumoniae, and Escherichia coli isolates [1].

Moreover, DrugPatentWatch.com, a comprehensive database for patent information on drugs, does not list any newly discovered bacteria with increased tigecycline resistance as of now [2].

In conclusion, while there is an increasing trend of tigecycline resistance in known bacteria, there is no specific information available on newly discovered bacteria with increased resistance to this antibiotic.
