Summary: This study aimed to determine the incidence of late onset sepsis and the most frequent causative microorganisms in the neonatal unit at Hospital Cayetano Heredia in Lima, Peru. The results showed that late onset sepsis was more prevalent in low birth weight infants, with gram-negative bacteria being the main causative microorganism in very low birth weight infants.

Summary: This study identified a multi-antibiotic-resistant strain Chryseobacterium sp. POL2 from livestock wastewater carrying multiple ARGs and the integrative conjugative element ICECspPOL2 associated with four types of antibiotics. ICECspPOL2 can horizontally transfer to Elizabethkingia species, contributing to the dissemination of ARGs between Chryseobacterium and Elizabethkingia species, posing a clinical concern due to their association with significant infections and high mortality. Monitoring the spread of ICECspPOL2 in these bacterial strains is essential to prevent outbreaks of multidrug-resistant bacteria.

Summary: This study found that gram positive bacteria were the main cause of neonatal sepsis, with bacterial isolates showing high resistance to first and second-line empiric antibiotics used in the hospital. The high levels of antibiotic resistance patterns emphasize the need to modify empiric treatment regimens to consider the most effective antibiotics. Regular surveillance in hospital settings to monitor changes in pathogens and antibiotic resistance patterns is crucial for implementing optimal prevention and treatment strategies.

Summary: The purpose of this study was to evaluate the distribution of pathogens and trends in antibiotic resistance among neonatal sepsis cases. The main microbes causing neonatal sepsis were found to be CoNS and E. coli, and there were varying levels of antibiotic resistance among different strains. Therefore, regular surveillance of changes in pathogens and antibiotic resistance is crucial.

Summary: The widespread use of intrapartum antibiotic prophylaxis has changed the epidemiology of early-onset sepsis, with E. coli becoming the leading pathogen. Intrapartum antibiotic prophylaxis significantly reduces the risk of severe disease and death. However, it is important to note that approximately 10% of E. coli causing early-onset sepsis are resistant to first-line antibiotics.

Summary: Antibiotic resistance is a global concern, with Elizabethkingia species like E. anophelis and E. meningoseptica being resistant to multiple antibiotics. Researchers are exploring new antibiotics that target unconventional sites, such as bacterial ribonucleotide reductases. This study evaluates the binding affinities of compounds inhibiting Pseudomonas aeruginosa growth by targeting its ribonucleotide reductase with enzymes from E. anophelis and E. meningoseptica to combat infections in the future.

Summary: Elizabethkingia spp. is a pathogenic bacterium that causes various diseases, especially in neonates and immunocompromised patients. Difficulties in accurately identifying the species of this bacterium using traditional methods may lead to an underestimation of the number of cases. The bacterium has an unusual antibiotic resistance pattern, suggesting an intrinsic origin for its multidrug resistance. Preventing and understanding Elizabethkingia spp. infections and limiting its spread is a new challenge.

Summary: In this study, two new phages, TCUEAP2 and TCUEAP3, infecting E. anophelis were isolated from wastewater. The results showed that both TCUEAP2 and TCUEAP3 belong to the Siphoviridae family and have an icosahedral head with a non-contractile tail. TCUEAP3 has a longer latent period and higher burst size compared to TCUEAP2, and both phages have a narrow host range.

Summary: This study retrospectively analyzed the etiology and antibiotic resistance profiles of bacteria in blood or cerebrospinal fluid cultures to evaluate the appropriateness of initial empirical therapy for neonatal sepsis. The results showed that early onset sepsis (EOS) was mainly caused by Gram-positive bacteria, while late onset sepsis (LOS) was predominantly due to Coagulase Negative Staphylococci (CoNS).

Summary: This study characterized hvKP/CR-hvKP strains causing neonatal sepsis in terms of resistance and virulence. About 26% of the strains belonged to hvKP, with hvKP-K2 being the prevalent pathotype. The majority of the strains exhibited strong biofilm-forming and high serum resistance ability. Additionally, this study reported for the first time the NDM-1-producing hvKP ST11-K2 and ST15-K54 strains causing fatal neonatal sepsis.

Summary: Although the HA-BSI rate in the neonatal unit decreased over the two periods, antimicrobial resistance rates in BSI pathogens remained high. Continuous surveillance of BSI is a valuable tool for detecting changes in pathogen and AMR profiles, and guiding empiric antibiotic recommendations for neonatal units in resource-limited settings.

Summary: This study in Stockholm, Sweden, found lower incidence of GNB sepsis in neonates compared to previous reports and low occurrence of antibiotic resistance. The in-hospital mortality and 5-day case fatality rate were higher in GNB late-onset sepsis compared to uninfected controls but not in comparison to suspected sepsis.

Summary: The study found that 10 days of antibiotics in neonates with culture-positive sepsis, who have achieved clinical and microbiologic remission at day 7, is noninferior to 14 days of therapy. Larger trials are needed to confirm these findings.

Summary: This retrospective cohort study aimed to assess the impact of empirical use of polymyxin on mortality in septic patients with carbapenem-resistant gram-negative bacteria (CR-GNB) infections. The study found that the empirical use of polymyxin did not decrease crude mortality in this setting.
