Ceftaroline hydrochloride
Based on 1 publication(s) in Google Scholar
Ceftaroline hydrochloride is a cephalosporin compound and the active form of Ceftaroline fosamil (HY-14737). Ceftaroline hydrochloride exhibits activity against Gram-positive bacteria, Gram-negative bacteria, and some anaerobic bacteria. Ceftaroline hydrochloride binds to penicillin-binding proteins 2 and 2A, thereby inhibiting the synthesis of bacterial peptidoglycan and cell wall, and acts as a bactericide, synergist, and resistance inhibitor. Ceftaroline hydrochloride can be used in research related to complicated skin and soft tissue infections, community-acquired pneumonia, Enterococcus faecalis infective endocarditis, and bacterial infections.

Description
In Vitro
Ceftaroline hydrochloride (T-91825 hydrochloride) in combination with Daptomycin (HY-B0108) exhibits synergistic in vitro activity against all tested endocarditis-associated HLAR and non-HLAR Enterococcus faecalis isolates at standard initial inoculum, prevents daptomycin resistance development, and shows bactericidal activity against two HLAR strains[2].
Ceftaroline (6-24 h) hydrochloride exhibits rapid, potent bactericidal activity against MRSA strains OFU4 and TY6242 at concentrations of 2 MIC and higher, reducing viable cell counts significantly over 24 h[4].

In Vivo
Ceftaroline hydrochloride, delivered via its prodrug TAK-599 (20 mg/kg; s.c.; three times daily; starting 2 hours post infection or day 1 and day 2 post infection), significantly reduces MRSA bacterial counts in the lungs of neutropenic mice, even when treatment is initiated at a late stage of infection[4].
Ceftaroline hydrochloride, delivered via its prodrug TAK-599 (20 mg/kg; s.c.; three doses; at 2, 20, and 26 hours post infection), reduces MRSA bacterial counts in mouse thigh muscle to 0.1% or less of control levels[4].

Anaerobic Bacterial Culture
Anaerobic bacterial culture detects viable bacteria that can grow under oxygen-depleted conditions; the readout is visible colony formation or broth turbidity after incubation in a chamber, jar, pouch, bag, or roll-tube system that maintains anaerobiosis. Oxygen control is central to the method because recovery depends on limiting oxygen exposure during collection, transport, inoculation, and incubation.

Gram Staining of Tissue Sections
Gram staining of tissue sections is a histochemical technique used to differentiate Gram-positive and Gram-negative bacteria within histological specimens based on differences in bacterial cell wall structure and dye retention, adapted from classical bacteriological Gram staining into tissue-compatible “histological Gram stain” variants. In tissue applications, modifications of the Brown-Hopps and Brown-Brenn methods are commonly used to improve differentiation of microorganisms embedded within host connective tissue and to reduce overstaining or loss of Gram-negative signal, which are known limitations of earlier approaches. The principle relies on crystal violet-iodine complex retention in Gram-positive organisms and subsequent decolorization and counterstaining steps that allow contrast visualization of Gram-negative organisms against tissue background.
