Global Pandemic

Community-acquired pneumonia is an acute infection of lung parenchyma which causes local and systemic inflammatory changes via cytokines. Several bacteria and viruses are responsible for this type of pneumonia, and the most common bacterial cause is Streptococcus pneumoniae. The classic symptoms are cough, fever, and pleuritic chest pain. In the Winter of 2020, a new strain of coronavirus known as SARS-CoV-2 spread throughout the world and was responsible for a global pandemic that transformed the way we live our lives. A 93-year old female presented to the hospital with respiratory distress and was found to have not only COVID-19 pneumonia but also superimposed Methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa pneumonia. Following the most up-to-date guidelines, she was determined to have community-acquired pneumonia. Methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa are uncommon causes of communityacquired pneumonia. She was treated with the standard of care at the time, which included vancomycin, piperacillin-tazobactam, and hydroxychloroquine. This case highlights the rarity of this specific presentation of community acquired pneumonia in regards to microbial etiology. It showcases that patients may develop certain diseases despite not having any risk factors. A major takeaway point is that apt decision making is a critical and time sensitive matter when determining whether a bacterial co-infection is present since it can affect patient outcomes. Since co-infections are relatively infrequent, antibiotic use in COVID-19 positive patients needs to be tailored accordingly. At the same time, it is crucial to keep in mind that co-infections are associated with increased severity of COVID-19 as well as poorer outcomes.

Abstract We identified deep diabetic foot infections by culture and conducted a case–control study examining the risk factors for moderate to severe methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa (PsA) diabetic foot infections. Our MRSA prevalence was lower than literature values; PsA was higher. Gangrene may be predictive of Pseudomonas infection.

Small Molecule Library

A small molecule library consisting of 45 compounds was synthesized based on the bacterial metabolite ethylN-(2-phenethyl) carbamate. From this library, a more potent, broad-spectrum inhibitor of MRSA biofilm formation was discovered.
