In monkeypox virus (MPXV) transmission caused by contaminated material, we have to consider that recently the outbreak of several MPXV cases was linked to tattoo parlors in Cadiz, Spain. These tattoo parlors did not cause a single outbreak, but instead are an established transmission route for MPXV, underscoring the need for increased awareness. We recommend increasing awareness among tattooists and piercers not only to protect their own safety and health, but also to prevent spreading the virus to their customers...

Campylobacter upsaliensis is an emerging pathogen implicated in human gastroenteritis. Contact with pets, especially dogs, has been identified as a risk factor. Fourteen (14) C. upsaliensis isolates were obtained from household dogs in Metro Manila, Philippines. Antimicrobial susceptibility testing (AST) determined high resistance to ciprofloxacin (92.86%), erythromycin (100%), and tetracycline (100%). Multilocus sequence typing (MLST) identified 14 novel sequence types and 1 novel clonal complex, which is suggestive of a high genotypic diversity within C...

Antibiotic-resistant S. aureus infections can be life-threatening. Linezolid is known to hinder S. aureus biofilm formation, but the underlying molecular mechanism remains unclear. Molecular docking revealed that linezolid can bind to icaA, and this was confirmed by thermal drift assays. Linezolid demonstrated a dose-dependent inhibition of icaA enzyme activity. Mutating Trp267, a key residue identified through molecular docking, significantly decreased linezolid binding and inhibitory effects on mutant icaA activity...

Staphylococcus aureus is a gram-positive bacterium that can produce biofilm, and biofilm-associated infections are difficult to control. Biofilm prevents antibiotics from penetrating and killing the bacteria. Combined use of antimicrobials is a common strategy to treat S. aureus biofilm-related infections. In this in vivo study, the clinically isolated strain of S. aureus 17546 (t037) was selected to establish a biofilm-associated infection rat model, and baicalin and linezolid were used to treat the infection...

The circumstances of death and the estimation of the post-mortem interval (PMI) are often a great challenge for scientific and judicial investigators, especially when some time has elapsed since death. Several techniques are used; nevertheless, each presents its own limitations. In the quest for new techniques that are more reliable or at least complementary to those existing and sometimes less expensive, researchers have in recent years turned toward exploring the dynamics of the different microbial communities of a corpse according to their different stages of decomposition...

The pillar of treatment success, defined as viral suppression and immune restoration, should be integrated into a modern vision of therapeutic success with pharmacological attributes of ART, such as potency, forgiveness, and genetic barrier of single drugs and regimens, as well as their longterm tolerability and safety. Moreover, the longterm success of lifelong treatment cannot be separated from the opinions and preferences of PLWH. Regimen Optimization in the setting of HIV suppression may reduce pill burden, and/or dosing frequency, enhance tolerability and/or decrease toxicity, prevent or mitigate DDIs, eliminate food/fluid requirements, relieve pill fatigue, decrease stigma or concerns associated with taking oral med, allow pregnancy, reduce costs (DHHS 2023)...

Management of heavily treatment experienced (HTE) people with HIV remains a challenge. Tailored antiretroviral therapy (ART) is needed in this fragile population who almost invariably harbor viral quasispecies with resistance-associated mutations (RAMs). The reference method for HIV genotypic resistance testing (GRT) has long been Sanger sequencing (SS), but next-generation sequencing (NGS), following recent progress in workflow and cost-effectiveness, is replacing SS because of higher sensitivity. From the PRESTIGIO Registry, we present a case of a 59-year-old HTE woman who failed darunavir/ritonavir plus raltegravir at low-viremia levels due mainly to high pill burden and poor adherence...

Lactococcus species are micro-aerophilic Gram positive bacteria characterized by low virulence features and other biotechnological properties of industrial interest. They are thus widely employed in food fermentation processes. Despite its low pathogenic potential and food grade safety, L. lactis may, however, rarely cause infections, especially among immunocompromised hosts. Moreover, the growing complexity of patients implies increased detections of such infections. This said, there is a paucity of data concerning L...

We report a case of a 26-year-old female who developed a brain abscess that was strongly suspected to be caused by Staphylococcus epidermidis, A. aphrophilus, and E. corrodens species. In general, A. aphrophilus and E. corrodens, members of the HACEK group (Haemophilus spp., Aggregatibacter spp., C. hominis, E. corrodens, and K. kingae), have been associated with the development of endocarditis, meningitis, sinusitis, otitis media, pneumonia, osteomyelitis, peritonitis, and wound infections. Cerebral abscesses are a rare manifestation of these bacteria; only a few cases are described in the literature, generally related to the diffusion of these organisms through the bloodstream after a dental procedure or a heart disease...

Ceftolozane (CTLZ) is a novel cephalosporin antibiotic that exhibits broad-spectrum activity against gram-negative pathogens, including Pseudomonas aeruginosa, especially when combined with tazobactam (TAZ). We examined the minimum inhibitory concentration (MIC) of CTLZ/TAZ for 21 multidrug-resistant P. aeruginosa (MDRP) and eight carbapenem-resistant P. aeruginosa (CRPA) strains isolated at Okayama University Hospital, Japan. Consequently, 81% (17/21) of the MDRP strains and 25% (2/8) of the CRPA strains were resistant to CTLZ/TAZ (MIC >8 μg/mL)...
