An Achromobacter xylosoxidans strain from the Tripoli central hospital produced a unique metallo-β-lactamase, designated TMB-1, which is related to DIM-1 (62%) and GIM-1 (51%). bla(TMB-1) was embedded in a class 1 integron and located on the chromosome. The TMB-1 β-lactamase has lower k(cat) values than both DIM-1 and GIM-1 with cephalosporins and carbapenems. The K(m) values were more similar to those of GIM-1 than those of DIM-1, with the overall k(cat)/K(m) values being lower than those for GIM-1 and DIM-1.

An 83-year-old male with a history of radial keratotomy and laser-assisted in situ keratomileusis (LASIK) presented with symptoms of a non-resolving corneal ulcer in the right eye that had been present for five months. The patient was treated with antibacterial, antiviral, and antifungal medications over that period, with multiple recurrences that prompted referral to our tertiary center for management. Following a 48-hour cessation of all medications, a corneal biopsy was performed which grew .

The effects of (Hp)-related chronic gastritis on gastrointestinal microorganisms or brain neurotransmitters are not fully understood. Here, this study selected SPF C57BL/6 mice to set up a Hp-related chronic gastritis experiment group and a blank control group, and used omics to explore the specific effects of Hp-related chronic gastritis on gastrointestinal microorganisms and brain neurotransmitters in mice. The Tyramine (TyrA) content in the female experiment group's brain was considerably reduced compared to the female control group ( < 0.

Infection of TIVADs is not uncommon and typically associated with coagulase negative staphylococci, though infection with other organisms does occur too. We report on the first case of a TIVAD infection caused by in person with cystic fibrosis.

Background: (AX) is an aerobic Gram-negative opportunistic bacteria known to inhabit various environments and is most commonly associated with nosocomial infections in immune-compromised patients. Although rare, AX can cause a variety of neurological infections, such as meningitis, ventriculitis, and osteomyelitis. Intravascular catheters, intrathecal pumps, and contaminated surgical instruments are potential vectors for such patients.
