Article Abstract
This study examined the removal of typical antibiotics from simulated swine wastewater. Microalgae-bacteria/fungi symbioses were constructed using Chlorella ellipsoidea, endophytic bacteria (S395-2), and Clonostachys rosea as biomaterials. The growth, photosynthetic performance, and removal of three types of antibiotics (tetracyclines, sulfonamides, and quinolones) induced by four phytohormones were analyzed in each system. The results showed that all four phytohormones effectively improved the tolerance of symbiotic strains against antibiotic stress; strigolactones (GR24) achieved the best performance. At 10 M, GR24 achieved the best removal of antibiotics by C. elliptica + S395-2 + C. rosea symbiosis. The average removals of tetracycline, sulfonamide, and quinolone by this system reached 96.2-99.4 %, 75.2-81.1 %, and 66.8-69.9 %, respectively. The results of this study help to develop appropriate bio enhancement strategies as well as design and operate algal-bacterial-fungal symbiotic processes for the treatment of antibiotics-containing wastewater.

Unlabelled: Microalgae treatment is regarded as a green and environmentally acceptable method of treating pig farm biogas slurry (BS). Numerous studies have been conducted on the use of microalgae to treat sterilized BS. Nevertheless, in large-scale application settings, this method will undoubtedly result in high costs and low efficiency.

Adults with short bowel syndrome (SBS), malabsorption, and malnutrition often require long-term parenteral nutrition (PN), typically as total PN (TPN). These patients are susceptible to bloodstream infections and sepsis. We present a case of a 63-year-old male patient who developed SBS following an acute mesenteric event.

Postoperative infections following orthopedic fixation can lead to devastating consequences, particularly in patients with comorbidities such as diabetes mellitus. We present a rare case of a 61-year-old female patient with a patella fracture treated with tension band wiring who developed a severe polymicrobial infection resulting in complete destruction of the patellar tendon. Multiple debridements, removal of implants, and prolonged targeted antibiotic therapy were necessary.

Rationale: Sepsis following hysteroscopy is an rare complication, with current evidence suggesting that routine prophylactic antibiotic administration may not be warranted. However, this does not imply that we should disregard vigilance regarding the potential occurrence of severe infections post-hysteroscopy.
Patient Concerns: A 27-year-old female underwent hysteroscopic resection of retained products of conception after incomplete medical abortion.

The activation of peroxymonosulfate (PMS) by biochar has shown promising potential for the efficient degradation and detoxification of antibiotics in wastewater. However, the underlying mechanisms are not fully understood. In this study, Fenton-conditioned sludge-derived biochar (FSBC) was prepared by microwave pyrolysis to activate PMS for the efficient degradation and detoxification of sulfamethoxazole (SMX).
