UMass Amherst tick researchers identify new strain of rickettsia bacteria that causes spotted fever infections in humans

Researchers at UMass Amherst's New England Center of Excellence in Vector-borne Diseases have identified a new strain of Rickettsia bacteria that causes spotted fever infections in humans. The discovery in Maine suggests rabbit ticks could be a zoonotic vector for serious infections, contradicting the usual dog tick vector.

Antibiotic resistance among key bacterial species plateaus over time

A study analyzing over 3 million bacterial samples found that antibiotic resistance initially rises but stabilizes over time, reaching an equilibrium in most species. The study suggests that continued increase in antibiotic resistance is not inevitable and provides new insights to monitor drug resistance.

Tuberculosis in children and adolescents: EU/EEA observes a rise in 2023

The European Centre for Disease Prevention and Control (ECDC) reports a rise in tuberculosis cases among children and adolescents in the EU/EEA, with a slight increase in the notification rate from 2.0 to 2.5 per 100,000 population. The highest proportion of paediatric TB was observed in children aged 1 to 4 years old.

Antibiotics of the future are prone to bacterial resistance

Recent studies have found that new antibiotics are prone to rapid development of resistance, even before they are widely used. This raises concerns about the effectiveness of these treatments in the long run. To address this issue, researchers call for a shift in antibiotic development prioritizing novel modes of action and responsible...

New study shows how salmonella tricks gut defenses to cause infection

A new UC Davis Health study has uncovered the mechanisms by which Salmonella bacteria evade the body's natural defenses in the gut. The research found that Salmonella alters the gut's nutrient environment to fuel its replication in the large intestine, creating an imbalance that helps the pathogen survive. This new understanding could ...
