PCR Detection of Oxacillinases in Bacteria.

Oxacillinases (OXA) have been mostly described in Enterobacteriaceae, , and species. Recent years have witnessed an increased prevalence of intrinsic and/or acquired β-lactamase-producing in food-producing animals. This study was conducted to assess the prevalence of OXA among selected bacterial species and to characterize these enzymes by analysis.

[Prevalence of strains of Staphylococcus epidermidis and other coagulase-negative staphylococci with biofilm-forming ability at a department of hemato-oncology].

Objectives: Staphylococcus epidermidis and coagulase-negative staphylococci generally are important causative agents of hospital-acquired infections. A significant role in this process is played by their common ability to form biofilm, a highly organized community of microorganisms adhering to inert surfaces. The study aimed to determine the prevalence of these bacterial strains and their ability to form biofilm at the Department of Hemato-Oncology, University Hospital Olomouc.

Occurrence and Antibiotic Resistance of Enterobacteriaceae in Acute Leukemia Patients.

Background: Acute leukemia (AL) is a heterogeneous group of malignant hematopoietic diseases and is divided into two basic types: acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL). Patients with these diseases are highly immunosuppressed and therefore at a high risk of serious infections. This study aimed to perform active surveillance of enterobacteria, which cause these infections, and to determine their antibiotic resistance in patients with AL who were hospitalized at the Hemato-Oncology Center of University Hospital Olomouc.

Antibiotic Susceptibility of spp. Isolated from Clinical Samples.

spp. have been recognized as causative agents of various severe infections in pre-term or full-term infants as well as elderly adults suffering from serious underlying disease or malignancy. A surveillance study was designed to identify antibiotic resistance among clinical spp.
