Objectives: To determine the impact of procalcitonin-guided antibiotic stewardship protocol (PCT-ASP) in children admitted with sepsis and lower respiratory tract infection on the duration of antibiotic therapy and clinical outcome.
Methods: This was a single-center study involving children with infections treated with antibiotic therapy according to the PCT-ASP as the study group. The control group consisted of children with same age and diagnosis who were treated with antibiotics according to individual unit protocol before the implementation of PCT-ASP. The primary outcome was median duration of antibiotic therapy and hospital stay.
Results: Among 127 patients, 66 were enrolled in the study and 61 in the control group respectively. The median (IQR) PCT values at admission, day 4 and day 6 of antibiotic therapy were 5.59 (61.3), 2.57 (47.35), and 0.35 (0.47) ng/ml respectively, and showed a decreasing trend. All the children in the control group received antibiotics at admission while 12% of children in the study group were not initiated on antibiotics. In the study group, 53% of the children received antibiotics only for three days in the absence of treatment failure. The duration of antibiotics (p = 0.001) and hospital stay (p = 0.03) were less in the study group when compared to the control group.
Conclusions: PCT-ASP reduces the duration of antibiotics and duration of hospital stay without increasing morbidity and mortality.

Treatment with antibiotics is a major risk factor for infection, likely due to depletion of the gastrointestinal microbiota. Two microbiota-mediated mechanisms thought to limit colonization include the conversion of conjugated primary bile salts into secondary bile salts toxic to growth and competition between the microbiota and for limiting nutrients. Using a continuous flow model that simulates the nutrient conditions of the distal colon, we investigated how treatment with 6 clinically used antibiotics influenced susceptibility to infection in 12 different microbial communities cultivated from healthy individuals.

is a vital zoonotic pathogen known for its extensive drug resistance and ability to form biofilms, which contribute to its antibiotic resistance. In this study, the phage vB_C4, specifically targeting , was isolated and subjected to bioinformatic analysis and bacteriostatic activity assays. The combination of phage vB_C4 with antibiotics such as cephalothin and cefoxitin, which target the bacterial cell wall, resulted in a significantly enhanced bacteriostatic effect compared to either the phage or antibiotics alone.

Compared with uncomplicated urinary tract infections (UTIs), complicated UTIs (cUTIs) including acute pyelonephritis (AP) present with significant morbidity, a higher risk of treatment failure and typically require longer courses of treatment, or alternative antibiotics. The emergence of drug-resistant organisms represents a considerable challenge in the treatment of patients with cUTIs/AP and has limited antibiotic options. Carbapenems are considered the current last line of therapy, however, carbapenem resistance represents a growing problem.
