Streptococcus agalactiae (S. agalactiae) is a rare cause of infective endocarditis, which is associated with a high mortality rate. Endocarditis in adults is generally related to immunocompromised states. We hereby report the case of a 35 year old man who presented with fever and delirium in whom aortic valve endocarditis due to S. agalactiae was detected. Though most patients with S. agalactiae endocarditis need surgical intervention along with antibiotics, our patient improved with medical therapy alone.

is a major causative agent of streptococcosis in Nile tilapia () and understanding its etiology is important to ensure the sustainable development of global tilapia farming. Our research group recently observed contrasting disease patterns in animals infected with two different serotypes (Ib and III). To better understand the basis for these divergent responses, we analyzed the brain transcriptome of Nile tilapia following bacterial exposure.

Due to its lack of the L-gulonolactone oxidase () enzyme, Nile tilapia is unable to synthesize vitamin C; thus, it requires an adequate level of exogenous vitamin C in its diet. To enhance antioxidant properties and vitamin C-related effects, we employed recombinant technology to integrate the -encoding gene into the chromosome. In this study, fish were divided into four groups: those fed with a basal diet (CON), a basal diet + vitamin C (VC), a basal diet + wild-type (BS), and a basal diet + recombinant (BS+GULO).

This review summarizes key virulence factors associated with group B (GBS), a significant pathogen particularly affecting pregnant women, fetuses, and infants. Beginning with an introduction to the historical transition of GBS from a zoonotic pathogen to a prominent cause of human infections, particularly in the perinatal period, the review describes major disease manifestations caused by GBS, including sepsis, meningitis, chorioamnionitis, pneumonia, and others, linking each to specific virulence mechanisms. A detailed exploration of the genetic basis for GBS pathogenicity follows, emphasizing the roles of capsules in pathogenesis and immune evasion.

Background: Group B Streptococcus (GBS) colonization is one of the major causes of severe neonatal infections. The study was intended to identify GBS colonization in pregnant women, explore its potential risk factors, and analyze the impact of GBS on outcomes for both mothers and newborns.
Material And Methods: A retrospective research was carried out on pregnant women who had undergone GBS screening and delivered from June 2020 to December 2022.

Background: Neonatal sepsis is a leading cause of death in low- and middle- income countries (LMIC). Increasing antibiotic resistance in early onset (< 72 h of life) bloodstream infection (EO-BSI) pathogens in LMIC has reduced the effectiveness of the recommended empiric antibiotic regimen (ampicillin plus gentamicin).
Methods: We retrospectively analysed blood culture-confirmed EO-BSI episodes at nine neonatal units from three central and six peripheral hospitals in the Western Cape Province, South Africa between 1 January 2017 and 31 December 2018.
