Dissemination of High-Risk Clones among Bulgarian Fecal Carriage Isolates.

The gastrointestinal tract is an important reservoir of high-risk Enterobacteria clones and a driver of antimicrobial resistance in hospitals. In this study, patients from six hospitals in four major Bulgarian towns were included in this study. Overall, 205 cefotaxime-resistant isolates (35.

Coinfection of the intestinal tract with , and - a case report.

Most cases of acute diarrhea in adults are of infectious etiology, likely viral and self-limited. Among those with severe diarrhea, however, bacterial causes are responsible for most cases.Apart from the standard stool cultures, to increase the positive yield a novel multiplex molecular test can be performed simultaneously.

First detected OXA-50 carbapenem-resistant clinical isolates from Bulgaria and interplay between the expression of main efflux pumps, OprD and intrinsic AmpC.

. Carbapenems are often described as the most effective weapon against infections caused by multidrug-resistant bacteria especially those belonging to the group of non-fermenting bacteria such as . The main mechanisms leading to resistance are the hyperexpression of certain efflux pumps belonging to the resisto-nodular division and the lower expression of the transmembrane porin OprD, sometimes in combination with excessive production of the intrinsic AmpC.

Age Characteristics and Concomitant Diseases in Patients with Angioedema.

Background: Angioneurotic oedema (AE) is an unpredictable and dangerous disease directly threatening the patient's life due to a sudden onset of upper respiratory tract obstruction. The disease is associated with various causes and triggering factors, but little is known about the conditions that accompany AE.

Aim: The study aims to determine the age-specificities and the spectrum of concomitant diseases in patients with AE.

Multicentre investigation of carbapenemase-producing Klebsiella pneumoniae and Escherichia coli in Bulgarian hospitals - Interregional spread of ST11 NDM-1-producing K. pneumoniae.

Aim: The aim of this study was to investigate the mechanisms of beta-lactam-resistance and the clonal relatedness of carbapenem-nonsusceptible Klebsiella pneumoniae and Escherichia coli isolates, collected consecutively in eight centers in five Bulgarian cities from November 2014 to March 2018. Carbapenemase-producing enterobacteria were detected in all but one centers. Overall, 104 K.

Antidepressant-like effect of salidroside and curcumin on the immunoreactivity of rats subjected to a chronic mild stress model.

Deregulated cytokines' production is found in depressed patients. Salidroside and curcumin both have been described with potential antidepressant-like activities. The present study investigated the effect of pure salidroside, curcumin and their combination on the immunoreactivity of animals, subjected to a chronic mild stress (CMS) model, followed by lipopolysaccharide (LPS)-induced inflammation.

Carbapenemase Production of Clinical Isolates Acinetobacter baumannii and Pseudomonas aeruginosa from a Bulgarian University Hospital.

Background: Production of Bla OXA-23, OXA-24, OXA-58 and hyperexpression of OXA-51 due to ISAba1 insertion sequence are the leading causes of carbapenem resistance in Acinetobacter baumannii. The loss of OprD transmembrane protein and the overexpression of some effl ux pumps are considered to be the main factors for carbapenem resistance in Pseudomonas aeruginosa whereas metallo-enzymes' production has a secondary role.

Aim: Тo examine the carbapenem resistance due to carbapenemase production among clinically signifi cant Gram-negative non-fermenters from St George University hospital, Plovdiv: A.

Beneficial Effect of Chronic Treatment with Extracts from Rhodiola Rosea L. and Curcuma Longa L. on the Immunoreactivity of Animals Subjected to a Chronic Mild Stress Model.

Background: Recent studies have suggested increased levels of pro-inflammatory cytokines in depression.

Aim: The present study aimed to evaluate the effect of extracts from Rhodiola and Curcuma on immunoreactivity of animals subjected to a chronic mild stress (CMS) model followed by lipopolysaccharide-induced inflammation.

Materials And Methods: Male Wistar rats (n=56) divided in 7 groups were treated orally with: distilled water 10 ml/kg (control and CMS model groups); Rhodiola 250 mg/kg; Rhodiola 500 mg/kg; Curcuma 250 mg/kg; Curcuma 500 mg/kg, Rhodiola 250 mg/kg and Curcuma 250 mg/kg.

Evaluation of antimicrobial resistance among Salmonella and Shigella isolates in the University Hospital "St. George," Plovdiv, Bulgaria.

The aim of this work is to study the epidemiology and antimicrobial resistance to the most commonly used antibiotics for the treatment of acute gastroenteritis caused by Salmonella and Shigella at the largest Bulgarian hospital-University Hospital "St. George," Plovdiv-for the period 2009-2013. Two hundred ninety strains were in vitro tested for resistance to 15 antimicrobial agents.

Study on anti-inflammatory and immunomodulatory effects of clomipramine in carrageenan- and lipopolysaccharide-induced rat models of inflammation.

The aim of the present study was to evaluate the anti-inflammatory effect of clomipramine in carrageenan- and lipopolysaccharide-induced (LPS-induced) models of inflammation by investigating the changes in serum levels of the pro-inflammatory cytokine TNF-α and the anti-inflammatory cytokines IL-10 and TGF-β after single and repeated administration of the drug. In order to study the effect of single and repeated doses of clomipramine on carrageenan-induced paw oedema, male Wistar rats were divided in five groups ( = 8): control, positive control group and three experimental groups treated with 5, 10 and 20 mg/kg bw clomipramine, respectively. The effect of single and repeated doses of clomipramine on serum cytokine levels was studied as animals were divided in four groups: two control groups treated with saline and two experimental groups treated with clomipramine 20 mg/kg bw.
