Viridans Group Streptococci (VGS) are associated with high mortality rates in febrile neutropenia; yet there are no recent European pediatric studies to inform antimicrobial therapy. The aim of this study was to describe the characteristics, outcome, and resistance patterns of children with VGS bacteremia (VGSB) undergoing treatment of malignancy or hematopoietic stem cell transplant. Patients aged 0 to 18 years, admitted to a tertiary pediatric hemato-oncology center with VGSB, from 2003 to 2013, were included in the study. All data were collected retrospectively from medical records. A total of 54 bacteremic episodes occurred in 46 patients. The most common underlying diagnosis was relapsed acute lymphoblastic leukemia. Streptococcus mitis was the most frequent organism. A total of 30% of isolates were resistant to penicillin and 100% sensitive to vancomycin. There were 8 episodes (14.8%) of Viridans Group Streptococcal Shock Syndrome; 6 resulted in admission to intensive care and 3 of these patients died of multiorgan failure. The potentially fatal nature of VGSB is confirmed. The high risk in relapsed acute lymphoblastic leukemia is of note. Research is needed to develop risk-stratification scores that identify children at risk of Viridans Group Streptococcal Shock Syndrome to guide empirical antimicrobial therapy in febrile neutropenia.

First isolation of from clinical specimens collected on a pig farm in Poland.

J Vet Res

December 2024

Department of Infectious, Invasive Diseases and Veterinary Administration, Institute of Veterinary Medicine, Faculty of Biological and Veterinary Sciences, Nicolaus Copernicus University in Toruń, 87-100 Toruń, Poland.

Introduction: Successful retrieval of from porcine clinical specimens has been rarely described, and data has only been obtained from a few swine-producing countries. Therefore, the aim of this study was the isolation of recovered from a specimen originating from a commercial pig farm located in Poland.

Material And Methods: Seven dead 12-week-old pigs weighing 24-26 kg with joint swelling of the hind legs were selected on a modern farrow-to-nursery farm in Poland in October 2023.

Monitoring of Antibiotic Resistance Patterns Within Al-Karak Governmental Hospital, Jordan, in 2022.

Antibiotics (Basel)

December 2024

Department of Pharmaceutics and Pharmaceutical Technology, Faculty of Pharmacy, Mutah University, Al-Karak 61710, Jordan.

: Antimicrobial resistance is considered one of the foremost global public health challenges, and its prevalence is increasing. In Jordan, particularly in Al-Karak Governorate, there is a lack of sufficient data on antimicrobial resistance to make accurate assessments. The main aim of the current study was to evaluate antibiotic resistance trends in clinical specimens from 2022 and assess antibiotic resistance patterns.

Background: This study aimed to summarize the pathogenic spectrum of infective endocarditis (IE) and analyze the risk factors for poor prognosis in surgical patients in a tertiary hospital in China.

Methods: We retrospectively included patients diagnosed with IE between January 2013 and January 2022. The pathogenic spectrum was summarized; the risk factors for early postoperative mortality and embolic events were analyzed using multivariate logistic regression.

Objective: To establish the noninferiority of the rapid and sensitive multiplex polymerase chain reaction (M-PCR) method versus standard urine culture (SUC) in pediatric urinary tract infection (UTI) diagnostic testing.

Methods: A United States of America (USA)-based single-center prospective observational study of 44 female and four male patients aged 3-21 years old presenting to a Pediatric Emergency Department in New Jersey with clinically suspected UTI. Urine specimens were primarily collected via midstream voiding.

Article Synopsis
  • The genus Streptococcus includes both harmless and harmful bacteria that naturally reside in the human body, particularly in the female genital tract (FGT), where there are two main groups: the pathogenic group B Streptococci (GBS) and the commensal viridans group streptococci (VGS).
  • A novel strain named Streptococcus sp. K0074 was isolated from a vaginal swab of an endometrial cancer patient and showed potential as a commensal member of the VGS, specifically within the mitis subgroup.
  • This strain produced a bacteriocin-like substance that can inhibit the growth and biofilm formation of the harmful bacterium MRSA, suggesting it may play a significant
