Extended-spectrum beta-lactamase (ESBL) producing Enterobacteriaceae generally cannot be treated with penicillins and cephalosporins. However, some later generation cephalosporins, including cefepime, are poorly hydrolyzed by specific ESBL enzymes, and certain strains demonstrate in vitro susceptibility to these agents, potentially affording additional treatment opportunities. Moreover, the ability to adjust both dose and dosing interval of β-lactam agents allows treatment of strains with elevated minimal inhibitory concentrations (MICs) formerly classified in the intermediate range...

Exposure to ethanol (EtOH) or methamphetamine (MA) can lead to increase in extracellular glutamate concentration in the brain. Although studies from ours showed the effects of EtOH exposure on key glial glutamate transporters, little is known about the effects of sequential exposure to EtOH and MA or MA alone on certain glial glutamate transporters. In this study, we investigated the effects of sequential exposure to EtOH and MA on the expression of the major glutamate transporters, glutamate transporter 1 (GLT-1), as well as cystine/glutamate antiporter (xCT) and glutamate aspartate transporter (GLAST) in striatum and hippocampus...

BACKGROUND: Sepsis is characterized by the loss of the perm-selectivity properties of the glomerular filtration barrier (GFB) with consequent albuminuria. We examined whether the pharmacokinetics-pharmacodynamics (PK/PD) of ceftriaxone (CTX), an extensively protein-bound 3rd generation cephalosporin, is altered during early sepsis and whether an increase in urinary loss of bound-CTX, due to GFB alteration, can occur in this condition. METHODS: A prospective, experimental, randomized study was carried out in adult male Sprague-Dawley rats...

Foreign body-associated infection is often difficult to treat, given that the associated microorganisms are in a biofilm state. Previously, we showed that low-amperage direct electrical current (DC) reduces biofilms of Propionibacterium acnes formed on implant-associated materials in vitro Herein, low-amperage DC was compared to ceftriaxone or no treatment in a novel rat femur foreign body osteomyelitis model. A platinum implant seeded with 10(7) CFU/cm(2) as well as 10(9) CFU of planktonic P. acnes were placed into the femoral medullary cavity...

We report a case of ceftriaxone (CTX) treatment failure for bacteremia caused by Salmonella enterica subsp. enterica serovar Typhimurium, due to the in vivo acquisition of a blaCTX-M-27-encoding IncFII group transmissible plasmid. The original β-lactamase-susceptible isolate ST882S was replaced by the resistant isolate ST931R during ceftriaxone treatment. After relapse, treatment was changed to ciprofloxacin and the patient recovered. Isolate ST931R could transfer resistance to E. coli at 37 °C. We used whole-genome sequencing of ST882S and ST931R, the E...

A series of novel 7β-[2-(2-aminothiazole-4-yl)-2-(Z)-(alkoxyimino)acetamido]-cephalosporins having pyridinium-linked acyl cyanamide at the C-3 position were prepared and their antibacterial activities and pharmacokinetics profiles were evaluated. Most of the compounds exhibited potent antibacterial activities against penicillin-resistant Streptococcus pneumoniae (PRSP) and β-lactamase non-producing penicillin-resistant Haemophilus influenzae (BLNAR). Introduction of a propenyl group between the cephalospoin core and the side chains at the C-3 position improved the pharmacokinetics profile...
