citation needed] The commonly quoted figure of 10% of patients with allergic hypersensitivity to penicillins and/or carbapenems also having cross-reactivity with cephalosporins originated from a 1975 study looking at the original cephalosporins, and subsequent "safety first" policy meant this was widely quoted and assumed to apply to all members of the group. (wikipedia.org)
Recent papers have shown that a major feature in determining frequency of immunological reactions is the similarity of the side chains (e.g., first generation cephalosporins are similar to penicillins), and this is the reason the β-lactams are associated with different frequencies of serious reactions (e.g., anaphylaxis). (wikipedia.org)

Chlamydia trachomatis ) and reflecting concern about emerging gonococcal resistance, CDC's 2010 sexually transmitted diseases (STDs) treatment guidelines recommended combination therapy for gonorrhea with a cephalosporin (ceftriaxone 250 mg intramuscularly or cefixime 400 mg orally) plus either azithromycin orally or doxycycline orally, even if nucleic acid amplification testing (NAAT) for C. trachomatis was negative at the time of treatment ( 2 ). (cdc.gov)
Criteria for resistance to cefixime and ceftriaxone have not been defined by the Clinical Laboratory Standards Institute (CLSI). (cdc.gov)
Because dual therapy with ceftriaxone plus azithromycin is the only recommended gonorrhea treatment, increases in azithromycin and cephalosporin MICs are cause for concern that resistance to these antimicrobial agents might be emerging. (cdc.gov)
The percentage of isolates with elevated cefixime MICs increased during 2009-2010, then decreased during 2012-2013 after treatment recommendations were changed in 2010 to recommend dual therapy (with a cephalosporin and a second antibiotic) and a higher dosage of ceftriaxone. (cdc.gov)

Empiric therapy also depends on prevalence of cephalosporin-resistant S pneumoniae (DRSP). (medscape.com)
Such strategies implicitly presume that resistance leads to reduced bacterial fitness in an antibiotic-free environment, and therefore these resistant populations should be rapidly outcompeted by antibiotic-sensitive variants. (elifesciences.org)
In theory, the extent of fitness costs determines the long-term stability of resistance, and consequently, the rate by which the frequency of resistant bacteria decreases in an antibiotic-free environment. (elifesciences.org)
Trials optimizing timing of antibiotic administration with regard to known antimicrobial pharmacokinetic/pharmacodynamic properties (e.g., prolonging infusion times of β-lactams to reduce bacterial resistance) should also assist in improving outcomes in penetrating traumatic infections, which are increasingly antibiotic resistant.

However, the cost of resistance can be mitigated by compensatory mutations elsewhere in the genome, and therefore the loss of resistance may proceed too slowly to be of practical importance. (elifesciences.org)
We conclude that phenotypic reversion to the antibiotic-sensitive state can be mediated by the acquisition of additional mutations, while maintaining the original resistance mutations. (elifesciences.org)
However, in other cases, such deleterious side effects of resistance mutations are undetectable, and resistance can even confer benefits in specific, antibiotic-free environmental settings ( Maharjan and Ferenci, 2017 ). (elifesciences.org)
It is frequently assumed that such compensatory mutations mitigate the fitness costs of resistance mutations without affecting the level of resistance. (elifesciences.org)
As the range of targets for compensation is much broader, compensatory mutations are more likely than the reversion of resistance mutations. (elifesciences.org)
If compensatory mutations are indeed widespread, pathogens can reach both high level of resistance and high fitness. (elifesciences.org)

N. gonorrhoeae has developed antimicrobial resistance (AMR) to all drugs previously recommended for treatment of gonorrhoea. (biomedcentral.com)

This is thought to be due to the N-methylthiotetrazole side-chain of these cephalosporins, which blocks the enzyme vitamin K epoxide reductase (likely causing hypothrombinemia) and aldehyde dehydrogenase (causing alcohol intolerance). (wikipedia.org)
It confirmed that the enzyme belonged to a class A beta-lactamase which had 99% identity to the ampicillin resistance transposon Tn3 of pBR322. (lu.se)

Fueron analizadas un total de 668 cepas de Salmonella aisladas en los años 2017, 2018 y 2019 a partir de muestras clínicas humanas y de alimentos, en el Laboratorio Central de Salud Pública y/o remitidas por Laboratorios de la Red de Enteropatógenos. (bvsalud.org)

Submissions to pursue keflex cost regulatory approvals by the U. 2012 author: habceama Is cephalosporin antibiotic contain sulfa Penicillin Allergy - Amoxicillin Allergy - Cephalosporin Allergy Does keflex contain sulfa? (seagullindia.com)

The cephalosporin segment accounted more than two-fifths of the total beta-lactam and beta-lactamase inhibitors market share in 2018. (pharmiweb.com)

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)

Data in the present study adds to the existing evidence that the use of cephalosporins such as cefovecin may be ineffective in many cases (intrinsic resistance of Enterococcus spp ) and therefore should be avoided unless cystocentesis and signalment results support their use. (bvna.org.uk)
