UTHealth researchers say more rapid test for Group B strep successful

A rapid laboratory test for pregnant women to detect Group B strep has been developed and is highly valid, identifying GBS colonization in six and a half hours. This new test could help reduce the overuse of resources and minimize bacterial resistance by targeting patients with threatened preterm labor.

'Stressed' bacteria become resistant to antibiotics

Research found that stressed bacteria can spontaneously develop resistance to rifampicin, a commonly used antibiotic. This discovery has significant implications for the evolution of antibiotic resistance and may impact treatment options for serious bacterial infections such as tuberculosis and leprosy.

Scientists notch a win in war against antibiotic-resistant bacteria

Researchers at Harvard's Wyss Institute used sophisticated computer modeling and biotechnology to target ROS production in E. coli, rendering the bacteria more susceptible to existing antibiotics. The study provides a promising approach to boost the global antibiotic arsenal against deadly superbugs like tuberculosis.

Antibiotics cut death rate for malnourished children

Researchers found a 44% drop in mortality with cefdinir and a 36% drop with amoxicillin when antibiotics were added to therapeutic food treatment. This study has changed how children are treated worldwide, providing a lifesaving impact on hundreds of thousands of children annually.

Synthetic corkscrew peptide kills antibiotic-resistant Gram-negative bacteria

A synthetic corkscrew peptide has been shown to kill antibiotic-resistant Gram-negative bacteria by dissolving their double-layered membranes. The peptide, KLAKLAKKLAKLAK, was effective against a variety of strains of E. coli, A. baumanii, and P. aeruginosa, including multi-drug resistant strains.

Novel approaches needed to end growing scourge of 'superbugs'

Infectious disease experts call for novel approaches to end the growing scourge of 'superbugs,' citing 2 million annual infections and 100,000 deaths. The authors recommend new strategies to prevent infections, encourage economic investment in anti-infective treatments, and alter host-microbe interactions.

The secret sex life of the penicillin-producing fungus could make it more productive

Researchers have discovered a method to induce sexual reproduction in Penicillium chrysogenum, leading to the development of new strains with improved industrial characteristics. This breakthrough aims to increase penicillin production, making it cheaper to produce, and potentially applicable to other economically important fungi.

Drug resistance: 'Baby steps' can pay off big

Researchers developed a mathematical model to predict how specific mutations affect antibiotic resistance. They discovered that small changes can increase resistance by up to 500%, challenging the idea of big effects from big changes.

Antibiotic-eating bug unearthed in soil

Researchers have discovered a soil bacterium that degrades the common veterinary antibiotic sulfamethazine and uses it for growth. This finding challenges existing theories on antibiotic resistance and suggests that soil bacteria may be capable of breaking down antibiotics more rapidly, potentially reducing their impacts.

Engineered bacteria can make the ultimate sacrifice

Scientists have engineered Escherichia coli bacteria that can deliberately die to protect their population, promoting the survival of survivors. The altruistic behavior emerges after sufficient time has passed and can be controlled by tuning the extent of programmed cell death.

Electronic visits offer accurate diagnoses, may lead to overprescribing of antibiotics

Researchers found that e-visit patients were more likely to receive antibiotics and less likely to have relevant testing ordered by their physicians before receiving medication. Despite this, the study suggests that e-visits can improve access to care and convenience for patients without compromising quality.

Cholera discovery could revolutionize antibiotic delivery

Researchers at Simon Fraser University have discovered a Trojan horse-like mechanism that enables antibiotics to deliver directly into a bacterial cell. The method uses pilus filaments to transport antibiotics into bacteria, offering a new approach to treat deadly bacterial infections like cholera and Pseudomonas aeruginosa.

Antibiotic therapy improves moderate exacerbations of mild-to-moderate COPD

A multicenter trial found that antibiotic treatment with amoxicillin/clavulanate significantly improved clinical cure rates and prolonged the median time to next exacerbation in patients with mild-to-moderate COPD. Patients with elevated capillary C-reactive protein (CRP) levels were more likely to be cured without antibiotics.

Lyme retreatment guidance may be flawed

A statistical review of four studies on Lyme disease retreatment suggests flaws in design, analysis, and interpretation that challenge the evidence against treatment. The review found inconclusive results and potential benefits from antibiotics, leading experts to question the guidelines' recommendation against retreatment.
