Mahadhy A, Ståhl-Wernersson E, Mattiasson B, Hedström M. Rapid detection of mecA gene of methicillin-resistant Staphylococcus aureus by a novel, label-free real-time capacitive biosensor. ACTA ACUST UNITED AC 2020; 28:e00568. [PMID: 33318966 PMCID: PMC7724158 DOI: 10.1016/j.btre.2020.e00568] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2020] [Revised: 11/20/2020] [Accepted: 11/20/2020] [Indexed: 12/03/2022]
Abstract
Rapid detection of mecA gene from methicillinresistant Staphylococcus aureus. High sensitivity assay down to 10−13M of the target molecule. High resolution to detect mismatching DNA probes. Reusable sensor chip for repeated assays.
This work presents a rapid, selective and sensitive automated sequential injection flow system with a capacitive biosensor for detection of the mecA gene (the model chosen for this study), which emerges from methicillin-resistant Staphylococcus aureus. A DNA-based 25-mer capture probe was immobilized on the surface of a gold electrode which was integrated in the capacitive sensor system. A constant current pulse was applied and the resulting capacitance was measured. Injection of the target DNA sample to the sensor surface induced hybridization to occur between the target and the complementary sequence, which resulted in a shift in the measured capacitance (ΔC). The ΔC was directly proportional to the concentrations of the applied target probe with linearity ranging from 10−12 to 10−7 M. The biosensor had a detection limit of 6.0 × 10−13 M and a recovery of 95 % of the mecA gene when spiked in human saliva. The biosensor showed a promising selectivity. It could clearly discriminate single-base, two-base and twelve-base mismatch probes with a decrease in the signal strength by 13 %, 26 %, and 89 %, respectively relative to the signal strength of the complementary target probe. There was no significant signal observed for the non-complementary probe. The biosensor-chip could be re-used for more than 12 cycles with residual capacity of 94.5 ± 4.3 % and a RSD of 4.6 % by regenerating the biosensor-chip with a solution of 50 mM NaOH.

Modifying the lipophilic part of phenylthiazole antibiotics to control their drug-likeness. Eur J Med Chem 2019; 185:111830. [PMID: 31718945 DOI: 10.1016/j.ejmech.2019.111830] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Revised: 10/13/2019] [Accepted: 10/28/2019] [Indexed: 02/01/2023]
Abstract
Compounds with high lipophilic properties are often associated with bad physicochemical properties, triggering many off-targets, and less likely to pass clinical trials. Two metabolically stable phenylthiazole antibiotic scaffolds having notable high lipophilic characters, one with alkoxy side chain and the other one with alkynyl moiety, were derivatized by inserting a cyclic amine at the lipophilic tail with the objective of improving physicochemical properties and the overall pharmacokinetic behavior. Only alkynyl derivatives with 4- or 5-membered rings showed remarkable antibacterial activity. The azetidine-containing compound 8 was the most effective and it revealed a potent antibacterial effect against 15 multi-drug resistant (MDR)-Gram positive pathogens including Staphylococcus aureus, Streptococcus pneumoniae, Staphylococcus epidermidis and enterococci. Compound 8 was also highly effective in clearing 99.7% of the intracellular methicillin-resistant S. aureus (MRSA) harbored inside macrophages. In addition to the remarkable enhancement in aqueous solubility, the in vivo pharmacokinetic study in rats indicated that compound 8 can penetrate gut cells and reach plasma at a therapeutic concentration within 15 min and maintain effective plasma concentration for around 12 h. Interestingly, the main potential metabolite (compound 9) was also active as an antibacterial agent with potent antibiofilm activity.

Abstract
A novel series of phenylthiazoles bearing cyclic amines at the phenyl-4 position was prepared with the objective of decreasing lipophilicity and improving the overall physicochemical properties and pharmacokinetic profile of the compounds. Briefly, the piperidine ring (compounds 10 and 12) provided the best ring size in terms of antibacterial activity when tested against 16 multidrug-resistant clinical isolates. Both compounds were superior to vancomycin in the ability to eliminate methicillin-resistant Staphylococcus aureus (MRSA), residing within infected macrophages and to disrupt mature MRSA biofilm. Additionally, compounds 10 and 12 exhibited a fast-bactericidal mode of action in vitro. Furthermore, the new derivatives were 160-times more soluble in water than the previous lead compound 1b. Consequently, compound 10 was orally bioavailable with a highly-acceptable pharmacokinetic profile in vivo that exhibited a half-life of 4 h and achieved a maximum plasma concentration that exceeded the minimum inhibitory concentration (MIC) values against all tested bacterial isolates.

Genomic and transcriptomic differences in community acquired methicillin resistant Staphylococcus aureus USA300 and USA400 strains. BMC Genomics 2014; 15:1145. [PMID: 25527145 PMCID: PMC4630920 DOI: 10.1186/1471-2164-15-1145] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2014] [Accepted: 12/08/2014] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Staphylococcus aureus is a human pathogen responsible for substantial morbidity and mortality through its ability to cause a number of human infections including bacteremia, pneumonia and soft tissue infections. Of great concern is the emergence and dissemination of methicillin-resistant Staphylococcus aureus strains (MRSA) that are resistant to nearly all β-lactams. The emergence of the USA300 MRSA genetic background among community associated S. aureus infections (CA-MRSA) in the USA was followed by the disappearance of USA400 CA-MRSA isolates. RESULTS To gain a greater understanding of the potential fitness advantages and virulence capacity of S. aureus USA300 clones, we performed whole genome sequencing of 15 USA300 and 4 USA400 clinical isolates. A comparison of representative genomes of the USA300 and USA400 pulsotypes indicates a number of differences in mobile genome elements. We examined the in vitro gene expression profiles by microarray hybridization and the in vivo transcriptomes during lung infection in mice of a USA300 and a USA400 MRSA strain by performing complete genome qRT-PCR analysis. The unique presence and increased expression of 6 exotoxins in USA300 (12- to 600-fold) compared to USA400 may contribute to the increased virulence of USA300 clones. Importantly, we also observed the up-regulation of prophage genes in USA300 (compared with USA400) during mouse lung infection (including genes encoded by both prophages ΦSa2usa and ΦSa3usa), suggesting that these prophages may play an important role in vivo by contributing to the elevated virulence characteristic of the USA300 clone. CONCLUSIONS We observed differences in the genetic content of USA300 and USA400 strains, as well as significant differences of in vitro and in vivo gene expression of mobile elements in a lung pneumonia model. This is the first study to document the global transcription differences between USA300 and USA400 strains during both in vitro and in vivo growth.

Ceftaroline activity tested against bacterial isolates from pediatric patients: results from the assessing worldwide antimicrobial resistance and evaluation program for the United States (2011-2012). Pediatr Infect Dis J 2014; 33:837-42.

Abstract
BACKGROUND Ceftaroline, the active form of ceftaroline fosamil, is a cephalosporin with broad-spectrum bactericidal activity against resistant Gram-positive organisms, including methicillin-resistant Staphylococcus aureus, ceftriaxone-resistant Streptococcus pneumoniae and many Enterobacteriaceae species. Ceftaroline fosamil is approved in the United States for treatment of acute bacterial skin and skin structure infections and community-acquired bacterial pneumonia in adults. METHODS A total of 5291 consecutive unique pediatric patient strains of clinical significance were collected from 157 US medical centers. The isolates were identified locally and forwarded to a central monitoring laboratory for reference antimicrobial susceptibility testing. S. pneumoniae isolates from the 2011 to 2012 respiratory season were serotyped. Susceptibility results were analyzed according to patient age as follows: ≤ 1 years old (yo; 1857 strains); 2-5 (1342); 6-12 (1281) and 13-17 (811). RESULTS Methicillin-resistant Staphylococcus aureus rates were slightly lower in isolates from patients 13-17 yo (39.9%) compared with other age groups (48.2-51.5%), and ceftaroline was consistently active against S. aureus isolates from all 4 age groups [minimal inhibitory concentration (MIC50/90): 0.25-05/1 μg/mL; 99.8-100.0% susceptible]. Overall, 99.8% of methicillin-resistant Staphylococcus aureus were ceftaroline susceptible (MIC50/90: 0.5/1 μg/mL). All S. pneumoniae strains (1178) were ceftaroline susceptible (MIC50/90: ≤ 0.015/0.12 μg/mL), whereas ceftriaxone susceptibility varied from only 84.8 (≤ 1 yo) to 89.7% (13-17 yo). 19A was the most frequent serotype identified among S. pneumoniae and these isolates exhibited low susceptibility to ceftriaxone (42.4%) and most other antimicrobials tested. The highest ceftaroline MIC among Haemophilus influenzae (587 strains) was 0.12 μg/mL (100.0% susceptible), and β-lactamase production rates varied from 24.2 (13-17 yo) to 30.1% (6-12 yo); 27.9% overall. Ceftaroline was also active against β-hemolytic streptococci (556 strains, highest MIC, 0.06 μg/mL). Extended-spectrum β-lactamase (ESBL)-phenotype rates among Escherichia coli/Klebsiella spp. were 6.0/5.1, 11.0/11.5, 5.1/8.3 and 11.4/14.7% for the ≤ 1, 2-5, 6-12 and 13-17 yo age groups, respectively. Ceftaroline exhibited good activity against non-ESBL phenotype strains of E. coli and Klebsiella spp. (MIC90: 0.25 μg/mL for both organisms), but had limited activity against ESBL-producing strains. CONCLUSION Ceftaroline demonstrated potent in vitro activity when tested against S. aureus, S. pneumoniae, H. influenzae, β-hemolytic streptococci and non-ESBL-phenotype E. coli and Klebsiella spp. strains isolated from pediatric patients, independent of patient age.
