An Outbreak of Shiga Toxin-Positive Enteroaggregative Escherichia coli O104:H4 Related Hemolytic Uremic Syndrome in Turkey: A Multicenter Study.

Introduction: Serious outbreaks of Shiga toxin-producing Escherichia coli-associated hemolytic uremic syndrome (STEC-HUS) have been reported globally. In 2011, Germany experienced a significant outbreak of HUS caused by enteroaggregative E. coli (EAEC) O104:H4 strain.

[Investigation of Azithromycin Minimum Inhibitory Concentration Values and Carbapenem Resistance in Salmonella and Shigella Clinical Isolates].

Increasing resistance to first-line antibiotics used in the treatment of infections caused by Salmonella and Shigella species is emerging. Azithromycin presents a good alternative treatment option for Salmonella and Shigella infections. However, there are limited data regarding the susceptibility of azithromycin in Turkey.

Nanoparticle Enhanced Antibody and DNA Biosensors for Sensitive Detection of .

Bacteria-related pathogenic diseases are one of the major health problems throughout the world. is a genus of rod-shaped Gram-negative enterobacteria of which more than 2600 serotypes have been identified. Infection with can cause salmonellosis, a serious bacterial toxi-infection syndrome associated with gastroenteritis, and paralyphoid and typhoid fevers.

[Antimicrobial susceptibilities and molecular characterization of toxin-positive Clostridium difficile isolates: the first report on the presence of hypervirulent strains from Turkey].

Clostridium difficile infection is one of the most important hospital-acquired infections. Infections caused by hypervirulent C.difficile strains which produce toxins at high levels, have higher morbidity and mortality rates, more complications and relapses.

[Serotype distribution and antimicrobial susceptibilities of Salmonella strains recovered from environmental samples between 2008-2014].

Despite the measures taken and control applications worldwide, Salmonella infections continue to threat the public health. Since these infections also cause significant economical loss, the salmonellas continue to be forefront globally. The determination of Salmonella serotypes and their sources is important for epidemiological point of view.

Pyelonephritis Caused by Salmonella Anatum: An Unusual Case.

Salmonella species are a very rare cause of urinary tract infection in healthy children. This species is associated with a high incidence of genitourinary abnormalities and immune deficiencies. We report the first pediatric case of a healthy 9-year-old girl with pyelonephritis due to Salmonella Anatum.

Characterization of Shiga Toxin-Producing Escherichia coli Isolated from Humans between 2011 and 2014.

Although E. coli O157:H7 is the major serotype among Shiga toxin-producing Escherichia coli (STEC) strains, non-O157 serotypes have caused numerous outbreaks worldwide. We aimed to evaluate the distribution of serogroups, serotypes, virulence genes, and antimicrobial resistance of STEC strains recovered from stool samples.

[Determination of Salmonella serotypes by conventional and molecular methods].

Determination of Salmonella enterica serotypes is crucial for epidemiological studies. Salmonella serotypes are defined on the basis of somatic (O) and flagellar (H) antigens, both of which are present in the cell wall of Salmonella. The aim of this study was to compare the results of molecular serotyping obtained by multiplex polymerase chain reaction (mPCR) with conventional serotyping results.

A case of urinary tract infection due to Salmonella enterica serovar Virchow and review of the related literature.

Nontyphoid salmonella (NTS) serotypes can cause gastroenteritis, bacteriemia, and focal infections. However, these focal infections, including urinary tract infections (UTI), are occasionally observed; in particular, the presence of several predisposing factors, such as immunodeficiency and structural abnormality in the urinary tract, increase the possibility of the occurrence of infection. We present a case of UTI caused by Salmonella enterica serovar Virchow in an elderly and debilitated patient with benign prostatic hyperplasia (BPH).

[Investigation of verotoxigenic Escherichia coli O157:H7 incidence in gastroenteritis patients].

Escherichia coli O157:H7 is the most common serotype among verotoxigenic E.coli (VTEC) strains that cause haemolytic uremic syndrome. Although sporadic VTEC cases originating from Turkey and small outbreaks have been reported from our country, VTEC has not been routinely investigated in most of the diagnostic microbiology laboratories in Turkey and studies related to this topic are limited.

External quality assessment for the determination of diphtheria antitoxin in human serum.

Accurate determination of diphtheria toxin antibodies is of value in determining the rates of immunity within broad populations or the immune status of individuals who may be at risk of infection, by assessing responses to vaccination and immunization schedule efficacy. Here we report the results of an external quality assessment (EQA) study for diphtheria serology, performed within the dedicated surveillance network DIPNET. Twelve national laboratories from 11 European countries participated by testing a standard panel of 150 sera using their current routine method: Vero cell neutralization test (NT), double-antigen enzyme-linked immunosorbent assay (ELISA; DAE), dual double-antigen time-resolved fluorescence immunoassay (dDA-DELFIA), passive hemagglutination assay (PHA), toxin binding inhibition assay (ToBI), and in-house or commercial ELISAs.

Analysis of an outbreak of Salmonella enteritidis by repetitive-sequence-based PCR and pulsed-field gel electrophoresis.

Objective: The aim of this study was to investigate a large food-borne outbreak associated with eggs contaminated by Salmonella Enteritidis in a military unit using pulse field gel electrophoresis (PFGE) and the Repetitive-sequence-based PCR (rep-PCR) employing the DiversiLab system.

Materials And Methods: In mid-January 2008, a food-borne outbreak associated with S. Enteritidis occurred in a military unit located in the city centre of Isparta.

[Typing of Shigella sonnei strains isolated in some provinces of Turkey using antimicrobial resistance and pulsed field gel electrophoresis methods].

Shigella species may lead to large epidemics owing to their low infective doses and frequent transmission from person to person with high secondary attack rates. Shigella sonnei is one of the most prevalent causative agent of infectious gastroenteritis in developing and developed countries and it is the most frequently reported Shigella serotype from Turkey in recent years. The aim of this study was to determine the types of S.

Enterohemorrhagic Escherichia coli O157:H7: case report.

Enterohemorrhagic Escherichia coli (EHEC) is a significant bacterial pathogen of bloody diarrhea. Not only does it cause systemic complications, such as hemolytic uremic syndrome (HUS) (the most common cause of potentially preventable pediatric renal failure), but it also leads to large outbreaks of bloody diarrhea. Among EHEC serotypes that cause HUS, E.

[A case with fever of unknown origin during treatment for malaria: multi-drug resistant Salmonella typhi infection].

Typhoid fever is an acute infectious disease caused by Salmonella serotype Typhi, leading to endemic or epidemic outbreaks in tropical/ subtropical countries (especially in India, Southeast Asia, Central and South Africa). In this report, a 27 years old male patient with malaria has been presented. The patient was diagnosed to have malaria while working in Afghanistan, and received malaria treatment since one month.
