An increase in Group A Streptococcus vulvovaginitis was detected in 2023: The average number of cases per year was 13 during 2011-2017. Twenty-five and 27 cases were reported in 2018 and 2019 followed by a decline coinciding with the COVID-19 pandemic. The 2023 increase surpassed previous data.

Changes in Group A Streptococcus emm Types Associated with Invasive Infections in Adults, Spain, 2023.

An increase in invasive group A Streptococcus infection was detected in the northeast of Spain in November 2022. A postpandemic decline in the diversity of circulating emm types involved in invasive group A Streptococcus was observed, along with the emergence of emm49 in this geographic area.

Antibiotic Susceptibility and Clarithromycin Resistance Determinants in in the Northeast of Spain: A One-Year Prospective Study.

is one of the most widespread infections, and it is reaching alarming resistance levels worldwide. The recommended first-line empirical treatment differs according to the local rate of clarithromycin resistance. Macrolide resistance is mainly associated with three point mutations in the 23S rRNA gene.

Detection and pathological role of intestinal protozoa in children.

Introduction: Intestinal parasites are considered a growing public health problem, being protozoa the main cause of intestinal disease. The objective of our study is to compare the detection of intestinal protozoa by microscopy versus real-time PCR, as well as to determine the most prevalent protozoa in our environment in the paediatric population.

Method: An observational longitudinal study was carried out, both by microscopy and real time-PCR in stool samples from children (0- 15 years) received from April 2019 to March 2021.
