Article Synopsis
- The study focused on assessing the prevalence of Chlamydia psittaci among workers in Buenos Aires who interact with carrier birds and aimed to identify associated risk factors and symptoms of psittacosis.
- Out of 63 evaluated workers, 28.6% tested positive for the infection, with respiratory chronic conditions identified as a key risk factor.
- Despite the positive tests, none of the workers developed severe symptoms like atypical pneumonia, highlighting the need for ongoing testing and treatment to manage potential zoonotic diseases effectively.
Streptococcus pneumoniae is a major cause of severe invasive disease associated with high mortality and morbidity worldwide. A total of 2908 pneumococcal isolates were analyzed between 2006 and 2019. Gold standard pneumococcal serotyping (the Neufeld-Quellung reaction) was performed to identify the serotypes associated with infection in children < 5 years in Argentina and agar dilution method was carried out to determine their profiles to 14 antimicrobial agents.

Article Synopsis
- The PSERENADE project focuses on global surveillance of invasive pneumococcal disease (IPD) to assess the impact of pneumococcal conjugate vaccines (PCV10/13).
- Among 138 countries using PCV10/13 as of 2018, 109 had IPD surveillance systems, with data collected from 76, enabling a comprehensive analysis of 240,639 post-vaccine IPD cases.
- The dataset will aid in understanding the effectiveness of the vaccines across different demographics and vaccination schedules, influencing future immunization policies globally and nationally.
Purpose: The aim of this work was to evaluate and optimize the identification of Bordetella pertussis, Bordetella parapertussis and Bordetella bronchiseptica (usually known as the classical Bordetella species) using Bruker Biotyper matrix-assisted laser desorption ionization/time-of-flight mass spectrometry (MALDI-TOF MS).
Methodology: A set of 106 previously characterized clinical isolates was used. The results were interpreted according to the manufacturer's recommendations and, in addition, a new score value cutoff was used for species identification.
In Argentina, the epidemiological and molecular characteristics of Chlamydia psittaci infections are still not sufficiently known. A total of 846 respiratory and 10 ocular samples from patients with suspected human psittacosis were tested for C. psittaci from January 2010 to March 2015.
