Introduction: Streptococcus pneumoniae is an important bacterial pathogen, causing respiratory infection. Penicillin resistance in S. pneumoniae is associated with alterations in the penicillin binding proteins, while resistance to macrolides is conferred either by the modification of the ribosomal target site or efflux mechanism. This study aimed to characterize S. pneumoniae and its antibiotic resistance genes using 2 sets of multiplex PCRs. Methods: A quintuplex and triplex PCR was used to characterize the pbp1A, ermB, gyrA, ply, and the mefE genes. Fifty-eight penicillin sensitive strains (PSSP), 36 penicillin intermediate strains (PISP) and 26 penicillin resistance strains (PRSP) were used. Results: Alteration in pbp1A was only observed in PISP and PRSP strains, while PCR amplification of the ermB or mefE was observed only in strains with reduced susceptibility to erythromycin. The assay was found to be sensitive as simulated blood cultures showed the lowest level of detection to be 10cfu. Conclusions: As predicted, the assay was able to differentiate penicillin susceptible from the non-susceptible strains based on the detection of the pbp1A gene, which correlated with the MIC value of the strains.

Pneumococcal Bacteraemia

The incidence of Streptococcus pneumoniae bacteraemia has risen due to a worldwide increase in immunocompromised patients and antibiotic resistance. We describe three patients who experienced severe, including cardiovascular, complications of pneumococcal bacteraemia. Cardiovascular complications related to pneumococci may run a fulminant course. However, some of these life-threatening complications (eg, endocarditis and aortitis) may long remain unnoticed or be misdiagnosed and therefore delay correct treatment. We review the literature with regards to the incidence, diagnosis and treatment of these rare but possibly lethal and hence important cardiovascular complications.

ABSTRACTBronchiectasis is a type of chronic obstructive pulmonary disease, defined as permanent abnormal dilation of bronchi due to vicious cycle of transmuralinfection and inflammation. Bronchiectasis is generally characterized by cough, wheeze, and dyspnea. Pathogens responsible for bronchiectasisinclude pathogens Haemophilus influenzae, Pseudomonas aeruginosa, Streptococcus pneumoniae, Staphylococcus aureus, and nontuberculousmycobacteria. Empirical antibiotic therapy and other drugs are used empirically in the management of bronchiectasis.Here, we discuss a case ofinfectious exacerbation of bronchiectasis successfully treated with an empirical use of ceftriaxone/sulbactam/disodium edetate-1034.Keywords: Bronchiectasis, Elores™, Ceftriaxone/sulbactam/disodium edetate-1034, Disodium edetate, Antibiotic resistance.
