[Special lesion on back of the hand].
Article
作者: van den Oord, Lotte J ; de Mare, Saskia
A 74-year-old man, previously healthy, presented at the Dermatology department with an asymptomatic hand lesion persisting for two months. The general practitioner initially treated the lesion with betamethasone and fusidic acid cream. Examination revealed a 3 cm livid plaque with central crusts. A biopsy confirmed cutaneous leishmaniasis tropica. The patient travelled to Greece, Spain, and Southern France before the lesion occurred, which is consistent with the endemicity of leishmaniasis in the Mediterranean. Treatment involved cryotherapy and antimony injections, resulting in lesion resolution after two sessions. This case underscores the importance of considering travel history and endemic diseases in diagnosing and managing dermatological conditions, especially in regions prone to specific infections.

The fungal natural product fusidic acid demonstrates potent activity against
Mycoplasma genitalium

ABSTRACT:
Antimicrobial resistance is extremely common in
Mycoplasma genitalium
, a frequent cause of urethritis in men and cervicitis, vaginitis, and pelvic inflammatory disease in women. Treatment of
M. genitalium
infections is difficult due to intrinsic and acquired resistance to many antibiotic classes. We undertook a program to identify novel antimicrobials with activity against
M. genitalium
from fungal natural products. Extracts of
Ramularia coccinea
contained a molecule with potent activity that was subsequently identified as fusidic acid, a fusidane-type antibiotic that has been in clinical use for decades outside the United States. We found that minimum inhibitory concentrations of fusidic acid ranged from 0.31 to 4 µg/mL among 17
M
.
genitalium
strains including laboratory-passaged and low-passage clinical isolates. Time-kill data indicate that bactericidal killing occurs when
M. genitalium
is exposed to ≥10 µg/mL for 48 h, comparing favorably to serum concentrations obtained from typical loading dose regimens. Resistance to fusidic acid was associated with mutations in
fusA
consistent with the known mechanism of action in which fusidic acid inhibits protein synthesis by binding to elongation factor G. Interestingly, no mutants resistant to >10 µg/mL fusidic acid were obtained and a resistant strain containing a F435Y mutation in FusA was impaired for growth
in vitro
. These data suggest that fusidic acid may be a promising option for the treatment of
M. genitalium
infections.

IMT-P8 potentiates Gram-positive specific antibiotics in intrinsically resistant Gram-negative bacteria
Article
作者: Nandanwar, Hemraj ; Singh, Vidhu
ABSTRACT:
Gram-negative bacteria (GNB) pose a major global public health challenge as they exhibit a remarkable level of resistance to antibiotics. One of the factors responsible for promoting resistance against a wide range of antibiotics is the outer membrane (OM) of Gram-negative bacteria. The OM acts as a barrier that prevents the entry of numerous antibiotics by reducing their influx (due to membrane impermeability) and enhancing their efflux (with the help of efflux pumps). Our study focuses on analyzing the effect of IMT-P8, a cell-penetrating peptide (CPP), to enhance the influx of various Gram-positive specific antibiotics in multi-drug resistant Gram-negative pathogens. In the mechanistic experiments, IMT-P8 permeabilizes the OM at the same concentrations at which it enhances the activity of various antibiotics against GNB. Cytoplasmic membrane permeabilization was also observed at these concentrations, indicating that IMT-P8 acts on both the outer and cytoplasmic membranes. IMT-P8 interferes with the intrinsic resistance mechanism of GNB and has the potential to make Gram-positive specific antibiotics effective against GNB. IMT-P8 extends the post-antibiotic effect and in combination with antibiotics shows anti-persister activity. The IMT-P8/fusidic acid combination is effective in eliminating intracellular pathogens. IMT-P8 with negligible toxicity displayed good efficacy in murine lung and thigh infection models. Based on these findings, IMT-P8 is a potential antibiotic adjuvant to treat Gram-negative bacterial infections that pose a health hazard.
