This structural similarity has led to considerable confusion regarding cross-reactivity of these drugs and the risks for allergic reactions from cephalosporins among penicillin-allergic patients. (cdc.gov)

In contrast, type IV and V are smaller, lack other resistance genes and are associated with community-acquired MRSA that occurred later and infected healthy people not in contact with healthcare facilities. (vin.com)
MRSA commonly acquires additional resistance determinants, giving rise to multidrug-resistant MRSA subtypes (MDRSA) which can be especially challenging to treat. (biosolveit.de)

All proposed inhibitors exhibit favorable predicted ADMET properties suitable for a lead-like candidate and predicted potencies surpass that of the preclinical benzamide TXA707 against the clinically relevant S. aureus MRSA252 strain and the G196S FtsZ mutant, the most common mutant conferring resistance to the benzamide, TXA707. (biosolveit.de)

A rapid process of sharing resistance exists among single-celled organisms, and is termed horizontal gene transfer in which there is a direct exchange of genes, particularly in the biofilm state. (wikipedia.org)
In general, resistance can either occur through a spontaneous mutation (which is transmitted only vertically through proliferation) or through acquisition of extrachromosomal genetic elements containing the genes responsible for the resistance (which can be transmitted via horizontal gene transfer). (vin.com)
This mecA gene is contained in a staphylococcal cassette chromosome mec (SCCmec), a genomic island that in some genotypes (types I-III) also contains additional resistance genes. (vin.com)
GMDNA often contains antibiotic resistance marker genes needed in the process of making GM organisms, but serves no useful function in the GM organism. (i-sis.org.uk)

Patients often are incorrectly labeled as allergic to penicillin and are therefore denied the benefit of a ß-lactam therapy. (cdc.gov)
Approximately 80% of patients with a true IgE-mediated allergic reaction to penicillin have lost the sensitivity after 10 years ( 658 ). (cdc.gov)

Gonorrhoea and widely spread antimicrobial resistance (AMR) in its etiological agent Neisseria gonorrhoeae are major public health concerns worldwide. (biomedcentral.com)

Additionally, other Enterobacterales had resistance against cephalosporins and penicillins. (bvna.org.uk)

Pseudomonas aeruginosa may be resistant to the cephalosporins. (vin.com)

Amino acid sequencing of some beta-lactamases has shown that substitution of only a few amino acids in the bla gene leads to high-level resistance against specific cephalosporins. (lu.se)

recent data has indeed shown that the cephalosporin cefovecin is a commonly prescribed antibiotic [iii] for cats presenting with lower urinary tract disease. (bvna.org.uk)

However, because of T. pallidum chromosomal mutations associated with azithromycin and other macrolide resistance and documented treatment failures in multiple geographic areas, azithromycin should not be used as treatment for syphilis ( 23,606-608 ). (cdc.gov)

3GC, third-generation cephalosporin. (cdc.gov)
Until now, no resistance to third-generation cephalosporins has been observed. (nih.gov)
Third generation cephalosporins are used in the treatment of enteric fever. (pediatriconcall.com)
Spectrum: Early penicillins target especially gram-positive and anaerobes, whereas newer agents (antipseudomonas penicillins and third generation cephalosporins) show a better gram-negative spectrum, but less gram-positive coverage. (vin.com)

And that was actually nine years before Alexander Fleming discovered penicillin, so it was the first antibacterial treatment. (cdc.gov)

The development of antibiotic resistance in particular stems from the drugs targeting only specific bacterial molecules (almost always proteins). (wikipedia.org)
In short, the lack of concerted effort by governments and the pharmaceutical industry, together with the innate capacity of microbes to develop resistance at a rate that outpaces development of new drugs, suggests that existing strategies for developing viable, long-term anti-microbial therapies are ultimately doomed to failure. (wikipedia.org)
This can be seen in cancerous tumors where some cells may develop resistance to the drugs used in chemotherapy. (wikipedia.org)
However, FLUTD is one of the most common reasons for the use of antimicrobial drugs in veterinary medicine and is therefore an important condition to consider to minimise antimicrobial use and development of antimicrobial resistance [ii] . (bvna.org.uk)
According to the World Health Organization, "more than any other issue, poverty and inadequate access to drugs continue to be a major force in the development of resistance. (jabfm.org)
N. gonorrhoeae has developed antimicrobial resistance (AMR) to all drugs previously recommended for treatment of gonorrhoea. (biomedcentral.com)

The gene responsible for the methicillin resistance is the mecA gene that encodes the penicillin-binding protein 2a. (vin.com)
And it's actually very important because methicillin resistance. (cdc.gov)

According to China antimicrobial resistance surveillance system in the first half of 2018, the ciprofloxacin-resistant rate was 57.8% for Escherichia coli , 35.4% for Klebsiella spp. (biomedcentral.com)

Because the drug is so specific, any mutation in these molecules will interfere with or negate its destructive effect, resulting in antibiotic resistance. (wikipedia.org)

Drug, toxin, or chemical resistance is a consequence of evolution and is a response to pressures imposed on any living organism. (wikipedia.org)
Recently, pneumococcus has shown increasing resistance to penicillin, the preferred drug for treating infection with this organism. (cdc.gov)

Moreover, compared with other phenotypic resistance patterns, bacteremia caused by FQR E. coli and Klebsiella spp. (biomedcentral.com)
and tetracyline resistance in 42.8 percent of Campylobacter jejuni and in 64.8 percent of Campylobacter coli. (foodsafetynews.com)
In the other data set, mutants of a bacterial enzyme that controls resistance to penicillins and cephalosporins, TEM-1 beta-lactamase, were expressed in E. coli under the selective pressure of an antibiotic treatment. (frontiersin.org)

Keflex has a significantly lower risk of antibiotic resistance compared with Bactrim (trimethoprim and sulfamethoxazole) or Augmentin (amoxicillin and clavulanic acid). (seagullindia.com)

For the first time, ESBL-producing Salmonella Kentucky with high resistance to ciprofloxacin has been detected in four countries, according to the report. (foodsafetynews.com)
