Background: Despite the rapid spread of antibiotic resistance in gonococci all over Southeast Asia, there is only limited surveillance for antibiotic susceptibility in Indonesia.
Goal: This study was undertaken to determine the frequency and diversity of antimicrobial resistance in gonococcal isolates from cohorts of female commercial sex workers in Bandung and Jakarta, Indonesia, and to characterize the Tet M plasmid among the tetracycline-resistant strains N gonorrhoeae.
Study Design: The antimicrobial susceptibility of 267 strains (85 strains from Bandung and 182 from Jakarta) to penicillin, spectinomycin, tetracycline, ciprofloxacin, cefotaxime, thiamphenicol, kanamycin, azithromycin, and trimethoprim-sulfamethoxazole (TMP-SMZ) was determined by agar dilution. Typing of the Tet M plasmid in tetracycline-resistant isolates was performed by PCR.
Results: Prevalence of penicillin and tetracycline resistance was extremely high: 60.0% of the isolates from Bandung and 70.9% of the isolates from Jakarta were resistant to penicillin. Of these, 60.0% and 62.1%, respectively, were penicillinase-producing N gonorrhoeae (PPNG). All the isolates from Bandung and 98.4% from Jakarta were resistant to tetracycline. All tetracycline-resistant isolates from Bandung and 97.8% from Jakarta carried a PCR fragment characteristic of the "Dutch" type Tet M plasmid. One isolate from Jakarta showed chromosomal resistance to tetracycline (0.6%). Chromosomal resistance to thiamphenicol (MIC, >/=2.0 microg/ml) was significantly higher in Jakarta than in Bandung (P < 0.05). All gonococcal isolates were susceptible to kanamycin, spectinomycin, cefotaxime, ciprofloxacin, and azithromycin.
Conclusion: Spectinomycin, fluoroquinolones, and azithromycin are still useful primary drugs for treatment of gonococcal infections in Indonesia. Continued surveillance of antimicrobial susceptibility should be part of gonorrhea control in Indonesia.

Chimeric antigen receptor (CAR)-based immune cell therapies attack neighboring cancer cells after receptor recognition but are unable to directly affect distant tumor cells. This limitation may contribute to their inefficiency in treating solid tumors, given the restricted intratumoral infiltration and immunosuppressive tumor microenvironment. Therefore, cell-cell fusion as a cell-killing mechanism might develop a novel cytotherapy aimed at improving the efficacy against solid tumors.

The global incidence of serovar Schwarzengrund has risen in recent years. This serotype has been isolated from poultry, retail meat, and other food products, leading to multiple outbreaks. Alongside the increase in infections, there are growing concerns about the increasing levels of antimicrobial resistance (AMR) among Schwarzengrund strains.

Background: Skin innervation is very important for normal wound healing, and receptor activity-modifying protein 1 (RAMP1) has been reported to modulate calcitonin gene-related peptide (CGRP) receptor function and thus be a potential treatment target. This study aimed to elucidate the intricate regulatory effect of RAMP1 on skin fibroblast function, thereby addressing the existing knowledge gap in this area.
Methods: Immunohistochemical staining and immunofluorescence (IF) staining were used to measure the dynamic changes in the expression of RAMP1 and α-smooth muscle actin (α-SMA) in skin wound tissue in mice.

Introduction: Hypervirulent carbapenem-resistant Klebsiella pneumoniae (hv-CRKP) poses an increasing public health risk due to its high treatment difficulty and associated mortality, especially in bone marrow transplant (BMT) patients. The emergence of strains with multiple resistance mechanisms further complicates the management of these infections.
Methods: We isolated and characterized a novel ST11-KL64 hv-CRKP strain from a pediatric bone marrow transplantation patient.

Article Synopsis
- Three species of Yersinia (Y. intermedia, Y. frederiksenii, and Y. kristensenii), common foodborne pathogens, were analyzed using genomic data to uncover their potential threat, revealing significant genomic diversity and a noteworthy presence in Europe and Asia.
- Y. intermedia demonstrated a high level of accessory genes, suggesting adaptability and the ability to acquire beneficial traits, while all three species contained various mobile genetic elements including plasmids and insertion sequences.
- Differences in antibiotic resistance genes and virulence gene composition were noted, with Y. kristensenii being the most virulent, containing the most virulence genes, while Y. frederiksenii showed unique pathogenic mechanisms.
