Article Synopsis
- This study investigates the effectiveness of bronchoalveolar lavage (BAL) versus endotracheal aspirate (ETA) cultures in treating secondary pneumonia in intubated COVID-19 patients, aiming to improve treatment outcomes.
- Patients were analyzed in two groups: those who underwent BAL and those who had ETA. Results showed BAL had a higher positivity rate for pathogens, longer ICU stays, and a trend towards lower mortality rates compared to ETA.
- The findings suggest that using BAL for pathogen isolation can lead to more effective antimicrobial treatment, thereby potentially improving patient prognosis and reducing mortality in critically ill COVID-19 patients.

Background: Mycoplasma gallisepticum (MG) has long been a pathogenic microorganism threatening the global poultry industry. Previous studies have demonstrated that the mechanism by which quercetin (QUE) inhibits the colonization of MG in chicks differs from that of antibiotics. However, the molecular mechanism by which QUE facilitates the clearance of MG remains unclear.

Dust and ammonia gas (NH) are two of the most abundant pollutants suspended in the air of poultry houses. Chronic inhalation of poultry dust and NH causes damage to the airways and reduces performance in broilers. Poultry dust is a mixture of organic and inorganic matter from feed, bedding material, manure, feathers, skin debris, and microorganisms.

Oral care is a crucial challenge of nursing care in orally intubated patients. Oropharyngeal colonization with microorganisms is probably the first step in the pathogenesis of most bacterial pulmonary infections. This study aimed to investigate the effect of different oral care solutions on the oral health status of critically ill patients.
