Although the measurement of aminoglycosides and glycopeptides in blood has been well established, it has become evident that therapeutic drug monitoring (TDM) should be extended to other antibiotics such as beta-lactams, daptomycin and linezolid. The use of a TDM guided approach allows reliable assessment of target concentration thus mitigating the risk for toxicity and preventing antibiotic resistance. This is especially relevant for the critically ill in intensive care. Herein we provide an overview on the different antibacterial antibiotics and their target pharmacokinetic/pharmacodynamic indexes in general as well as the importance for TDM of antibacterial antibiotics specifically. Analytical methods applicable to this approach in clinical laboratories are explored and highlighted.

Brucellosis, caused by a facultative intracellular gram-negative coccobacillus, is one of the most common zoonotic infections worldwide. Very rarely, brucellosis can cause periprosthetic joint infections (PJI). In this case-based literature review, we summarize the current medical literature regarding Brucella PJI, with the aim to raise awareness among clinicians, particularly in non-endemic areas.

Chryseobacterium indologenes is a rare human pathogen which is nowadays considered an emerging fearsome organism because of its upcoming antibiotic resistance. We present a quite unique case of a multi drug resistant C. indologenes surgical wound infection in a patient submitted to cannulated screw fixation of a displaced medial malleolus fracture.

Correct treatment of chronic osteomyelitis depends on proper identification of the bone-infecting microorganism, but it is difficult identify the specific etiology in previously treated patients and in those with implants. Small colony variants auxotrophyc for menadione had been related with false-negative results in culture of patient with chronic osteomyelitis, but menadione supplementation can increase bone culture performance. The purpose was to evaluate the effect of menadione supplementation on isolates in bone cultures, in a cohort of patients with osteomyelitis, Medellín- Colombia.

The concept of Debridement, Antibiotics and Implant Retention (DAIR) is well known in periprosthetic joint infections. Extrapolating this concept to fracture related infections is mired in controversies. Characteristics of the metal implant, duration of infection, state of fracture healing, microbiological profile etc.

To date, the abuse of antibiotics and a gradual decline in novel antibiotic discovery enlarge the threat of drug-resistant bacterial infections, especially methicillin-resistant (MRSA). Herein, inspired by the unique structures and antibacterial activities of 2-quinolones, a class of novel 2-quinolones with substituted pyridines was synthesized. Notably, compound , the derivative with a methylpyridine fragment, showed potent antibacterial and antibiofilm activities, especially for MRSA strains (MIC = 0.
