Article Synopsis
- Pseudomonas aeruginosa and Acinetobacter calcoaceticus-baumanii complex are dangerous pathogens in hospitals, with the ability to develop resistance to antibiotics and cause serious outbreaks.
- This research focused on identifying Metallo-β-lactamases (MBLs) in Paraguay's hospitals and examined the coexistence of different carbapenemases.
- The study found 70 MBL-producing strains primarily from Pseudomonas and Acinetobacter species, showing clonal spread in some cases and evidence of transmission between different bacterial strains.
Background: The double disc diffusion method is an alternative diagnostic that allows the identification of Staphylococcus aureus isolates apparently susceptible to clindamycin but that may develop resistance due to an induction phenomena, mainly asociated to the increase in resistance to methicillin, thus increasing the possibility of failure in the treatment.
Aim: To determine the frequency of induced clindamycin resistance in methicillin-resistant S. aureus (MRSA) isolated from Paraguayan children.
