This graphic shows about two-thirds of all antibiotic drug classes were developed during the "Golden Age of Antibiotics" from the early 1940s through the mid-1960s.

Since 1970, just 8 new classes of antibiotics have been approved.

For #invertefest, a spectacular specimen of one of my favorite invertebrates, the horseshoe crab Limulus polyphemus. These blue-blooded marvels have some of the coolest compound eyes in nature, *and* they produce compounds in their blood used to test for the presence of gram-negative bacteria. 🧪

The outer membrane of Gram-negative bacteria blocks many antibiotics. Our latest work reveals that L-type pyocins bypass this barrier by inactivating the BAM complex, killing Pseudomonas aeruginosa without entering the cell, providing a new blueprint for beating antibiotic resistance.
A Protein Antibiotic Inhibits the BAM Complex to Kill Without Cell Entry
Many antibiotics are ineffective against Gram-negative pathogens such as Pseudomonas aeruginosa because they cannot penetrate the bacterial outer membrane. Here, we show that protein antibiotics calle...

📊 Study on MRSA in Norway (2008-2017) analyzed 15,200 cases. Resistance rates stable; 41.4% resistant to cefoxitin. High co-resistance: erythromycin (31%), tetracycline (25.3%). Continuous surveillance needed.##idsky
Antimicrobial resistance trends of methicillin-resistant Staphylococcus aureus in Norway from 2008 to 2017
AbstractObjectivesThe purpose of this study was to analyse nationwide trends in antimicrobial susceptibility and molecular epidemiology of all MRSA strains in Norway over a 10-year period.Materials and methodsAll cases of MRSA in Norway from 2008 to 2017 were included, limited to the first case per year per individual (n = 15 200). Strains were confirmed as MRSA with PCR and genotyped using spa-typing. Antimicrobial susceptibility data and epidemiological data were collected from the Norwegian MRSA reference laboratory and the Norwegian Surveillance System for Communicable Diseases, respectively.ResultsDespite an increase in MRSA cases, antimicrobial resistance rates remained stable throughout the study period. The most common susceptibility profile of the MRSA strains was resistance to cefoxitin alone (41.4%), while co-resistance (58.6%) was observed most commonly for erythromycin (31.0%), tetracycline (25.3%) and ciprofloxacin/norfloxacin (21.6%). Notably, associations were identified between specific resistance patterns and clinical variables, including higher resistance rates among healthcare-associated MRSA, particularly in older adults and nursing home residents. Geographic associations were also observed, linking specific resistance profiles to strains acquired in North America, Africa and Asia.ConclusionsThe findings highlight a complex landscape of MRSA resistance in a low-prevalence country, characterized by a diverse genotypic population and stable longitudinal trends in resistance rates. However, the prevalence of co-resistance to one or more antibiotics among Norwegian MRSA strains was high and increasing. This study thus underscores the importance of continuous surveillance and adherence to antimicrobial guidelines.

Trial finds cefiderocol isn't superior to standard antibiotics for bloodstream infections

Cefiderocol was found to be noninferior for gram-negative bloodstream infections, but more evidence is needed in patients with carbapenem-resistant infections.

#UKHSA reports that the rate of discovery of ceftriaxone-resistant & extensively drug-resistant gonorrhea cases is accelerating in the UK.
This is bad news. For years gonorrhea has been evolving to evade the antibiotics available to cure it.
