Objective: To evaluate the susceptibility pattern of S. aureus and enterococci to teicoplanin using an in vitro method.
Methods: Between February and November 2011, valid bacteriological samples were collected at three hospitals in three cities in Pakistan and the organism was isolated. Only samples containing S. aureus or enterococci were tested for their sensitivity to teicoplanin and various other standard antimicrobials in therapy, using the disc diffusion testing by the Kirby-Bauer method. SPSS 18 was used for statistical analysis.
Results: Of the 401 isolates collected, a majority 293 (59.6%) were methicillin-sensitive S. aureus, while 136 (33.9%) were methicillin-resistant S. aureus; and 26 (6.5%) were enterococci. All isolates were sensitive to teicoplanin and vancomycin.
Conclusion: Teicoplanin had the same in vitro sensitivity as vancomycin against methicillin-sensitive S. aureus, methicillin-resistant S. aureus and enterococci in clinical isolates.

Fermented foods, particularly fermented dairy products, offer significant health benefits but also present serious concerns. Probiotic bacteria, such as lactic acid bacteria (LAB), found in these foods have been strongly linked to the selection and dissemination of antibiotic resistance genes (ARGs). This study aims to examine the potential risks associated with fermented foods, despite their importance in human nutrition, by analyzing the entire production chain from raw material acquisition to storage.

Background: Antibiotic resistance is a rapidly growing problem. Methicillin-resistant staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) are major worries, particularly in developing nations where cost-effectiveness is essential. Use of vancomycin must be restricted to prevent resistant to it.

Background: This study aimed to summarize the pathogenic spectrum of infective endocarditis (IE) and analyze the risk factors for poor prognosis in surgical patients in a tertiary hospital in China.
Methods: We retrospectively included patients diagnosed with IE between January 2013 and January 2022. The pathogenic spectrum was summarized; the risk factors for early postoperative mortality and embolic events were analyzed using multivariate logistic regression.

Electronic address:
Ten previously undescribed phyto-oxylipins siegesoxylipin A‒J (1-10), along with four known analogs (11-14), were isolated from the aerial parts of Sigesbeckia orientalis. The elucidation of their structures was accomplished through spectroscopic analyses, base-catalyzed hydrolysis and X-ray diffraction. Moreover, unmethylesterified 4-methylpentanoic acid siegesoxylipins 1, 2, and 4-7 exhibited potent inhibitory bioactivity against methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococci (VRE) strains with MIC values of 8 μg/mL, in which siegesoxylipin A (1) inhibited bacteria by inducing membrane damage.

The rise in antibiotic resistance limits the availability of antibiotics to treat bacterial infections. Despite this, antibiotic development pipelines remain sparse which makes using adjuvants to reverse antibiotic resistance a promising therapeutic strategy. The use of vancomycin, a frontline antibiotic used to treat hospitalized patients with methicillin-resistant (MRSA) infections, is complicated by high rates of treatment failure.
