The present study investigated the release of microplastics (MPs) from wastewater treatment plants (WWTPs) to the neighboring environment, including marine and coastal sediments, and fish. Here, we comprehensively investigated MP abundance in 34 samples of marine sediment, corresponding to 5,530.5 g of sediment (d.

Article Synopsis
  • Microplastics (MPs) are widely spread pollutants that negatively impact ecosystems, making it crucial to understand how wastewater treatment plants (WWTPs) contribute to this issue.
  • This study assessed the concentration and types of MPs from four WWTPs in Southeastern Spain over four years, analyzing over 1,200 liters of wastewater and isolating more than 3,200 microparticles.
  • The results showed removal efficiencies of MPs ranged from 64.3% to 89.2%, with notable differences in removal rates between fiber and particulate MPs, and higher levels of MPs found in wastewater during Autumn.

This paper presents the results on the presence and characterization of microplastics (MP) in the gastrointestinal tract of gilthead seabream ( L.), a species of commercial interest from the Mar Menor coastal lagoon in Southeast Spain. This is the first time that microplastic ingestion is recorded in any species from this semi-enclosed bay.

This paper presents the abundance and ubiquitous presence of microplastics in a protected coastal zone located in the southeast of Spain: The Mar Menor lagoon, an important tourist destination in this region. Seventeen sampling sites, corresponding to both intertidal and backshore points, were collected during winter 2017 and 2018, being situated in different protected areas according to international, European and Spanish environmental policies. The main objectives of the study were to examine microplastics in both protected and non-protected areas, and to test the importance of local activities on their presence.

Atopobium rimae and Parvimonas micra are both Gram-positive anaerobes involved infrequently in human infections. We report a polymicrobial anaerobic bacteremia caused by these microorganisms. A 43-year-old woman receiving coadjuvant chemotherapy due to a retroperitoneal leiomiosarcoma presented with nausea, vomiting, abdominal pain and fever (38 °C).

Article Synopsis
  • - Propionibacterium acnes plays a significant role in causing acne vulgaris and is also linked to medical-device infections, making its identification and classification crucial for understanding its impact on human health.
  • - The study validated the identification and typing of 24 clinical isolates of P. acnes using biochemical and genetic methods, revealing two main clusters associated with specific phylogroups through RAPD-PCR analysis.
  • - Most isolates from acne and opportunistic infections were categorized as biotype I-B3, primarily belonging to subgroup IA1, while remaining isolates were part of phylogroup II, which is typically found as part of the normal skin microbiota; antibiotic susceptibility tests showed no strong link to virulence.

In recent years, MALDI-TOF (matrix-assisted laser desorption ionization time-of-flight) mass spectrometry has become established as a first-line diagnostic tool in the identification of microorganisms, including those producing human infections. Rapid detection of antimicrobial resistance is one of the future applications of this technique with the greatest likelihood of success. This review describes the most important studies published in this field and discusses potential future challenges and the clinical application of this technique in the next few years.
