Netilmicin sulfate

The clinical isolates of Staphylococcus aureus (n = 102) were analyzed on sensitivity and to gentamicin, tobramicin, netimicin and amikacin. The disc diffusing technique was applied. The technique ofpolymerase chain reaction was applied to analyze all strains establishing presence in their genomes genes aac (6'-Ie/aph(2"), ant1, aac, ant(6)-Ia, aph (3')-IIIa and ant(4')-Ia coding amino-glycoside-modifying enzymes. The strains sensitive to amino-glycosides had no the given genes in genome. The genome of all strains resistant to amino-glycosides included no less than two of enumerated genes. The 100% correlation was established between phenotypic resistance of analyzed strains to amino-glycosides and availability in them of gene aac(6')-Ie/aph(2").

We evaluated aminoglycoside resistance in 87 Acinetobacter baumannii strains isolated from four hospitals located in the North West region of Iran and typed them in sequence groups (SGs) using trilocus sequence-based scheme to compare their clonal relationships with international clones. Resistance toward aminoglycosides was assayed by minimum inhibitory concentration (MIC) and presence of aminoglycoside-modifying enzymes (AMEs), and ArmA-encoding genes were evaluated in different SGs. The majority of isolates belonged to SG1 (39%), SG2 (33.3%), and SG3 (12.6%), whereas the remaining ones were assigned to six novel variants of SGs. MIC determination revealed netilmicin as the most and kanamycin as the least active aminoglycosides against all groups. Among the varied SGs, isolates of SG2 showed more susceptibility toward all tested aminoglycosides. APH(3'')-VIa-encoding gene was predominant in SG1 (47%), SG2 (62%), and SG6-9 (100%). However, AAC(3')-Ia (100%) and ANT(2')-Ia (90.

AIM: Characterize spectrum of antibiotics resistance of Acinetobacter baumannii strains, isolated from patients of 8 surgical and reanimation departments of 3 medical institution of Moscow, and determine molecular-genetic mechanisms of stability of their carbapenem-resistant forms.

Rare cases of high anion gap metabolic acidosis during long-term paracetamol administration in therapeutic doses with causative 5-oxoproline (pyroglutamic acid} accumulation have been reported. Other concomitant risk factors such as malnutrition, alcohol abuse, renal or hepatic dysfunction, comedication with flue/oxacillin, vigabatrin, netilmicin or sepsis have been described. The etiology seems to be a drug-induced reversible inhibition of glutathione synthetase or 5-oxoprolinase leading to elevated serum and urine levels of 5-oxoproline. Other more frequent differential diagnoses, such as intoxications, ketoacidosis or lactic acidosis should be excluded. Causative substances should be stopped. 5-oxoproline concentrations in urine can be quantified to establish the diagnosis. Adverse drug reactions, which are not listed or insufficiently described in the respective Swiss product information, should be reported to the regional pharmacovigilance centres for early signal detection.
