Various waste frying oils (WFOs) were evaluated as substrates for rhamnolipid production by Pseudomonas aeruginosa mutant EBN-8 in the presence or absence of rhamnolipid precursor, under single-/batch-fed conditions. Soybean WFO was the best substrate, producing 9.3 g rhamnolipid l(-1) with the specific product yield of 2.7 g g(-1) h, under batch-fed cultivation with the addition of rhamnolipid precursor. The surface tension of the cell-free culture broth (CFCB) was 29.1 mN m(-1 )and the interfacial tension against n-hexadecane was <1 mN m(-1). The hydrocarbon/ CFCB systems showed the relative emulsion stability to be in the range of 89.7-92.3.

Background & Objective: Chronic suppurative otitis media is a fatal condition owing to its propensity for intracranial extension. The inadvertent use of antibiotics has led to resistance among causative organisms. The objectives of this study were to determine causative bacteria, their antibiotic resistance and susceptibility patterns, and their response to antibiotics after a one-month follow-up.

Purpose: To describe the top three causative organisms of hospital acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) in Thailand.
Patients And Methods: This multi-center retrospective cohort study included HAP/VAP patients hospitalized in 2019 in three university-affiliated hospitals and a private hospital in Bangkok, Thailand. Medical records of patients with a documented diagnosis of nosocomial pneumonia (NP) were systematically reviewed to collect data on demographic, clinical, microbiological, and 30-day readmission due to NP.

Implantable cardiac devices, including cardiac pacemakers, are not without risk for infection, carrying a mortality and morbidity of around 5-15%. Gram positive organisms are most common in 91% of cases, whereas gram negative organisms are less common, found in 2% of cases secondary to gram negative organisms other than . Here, we present a rare case of the gram-negative organism leading to a pacemaker site infection.

This case report presents a complex and challenging scenario of recurrent () bacteremia and tricuspid valve endocarditis in a 77-year-old male patient with multiple comorbidities and indwelling medical devices. The patient's medical history was significant for T4 paraplegia, neurogenic bladder requiring a chronic indwelling suprapubic catheter, heart block status post-permanent pacemaker placement, type 2 diabetes mellitus, chronic kidney disease, and chronic sacral wounds. The case highlights the difficulties in managing antibiotic-resistant infections, particularly in patients with implantable devices and chronic wounds.

Melanonychia describes black pigmentation of the nail plate that results from either melanocyte activation (such as infections, local inflammatory disorders, local trauma affecting the nail plate, numerous systemic conditions, and medications) or melanocyte hyperplasia (such as benign neoplasms or malignant tumors) or blood (resulting from a trauma-associated subungual hematoma). The black dyschromia may include not only the nail plate but also the proximal nailfold. The Hutchinson sign refers to black discoloration of both the proximal nailfold and adjacent nail plate when the underlying pigmented lesion is a malignant melanoma.
