A nosocomial scabies outbreak originating from immunocompromised transplant patients in Turkey: Upholstery as a possible cause.

Background: Inpatients with crusted scabies represent an important source of nosocomial transmission with consequent outbreaks among patients and healthcare workers. This study aimed to report the course of an institutional scabies outbreak, which progressed with infestation of immunosuppressed transplant patients, health care workers, and caregivers.

Methods: Patients diagnosed with scabies in a nosocomial outbreak in a 200-bed, tertiary hospital were included.

Nasal colonization with methicillin-resistant Staphylococcus aureus at admission among high-risk Turkish and international patients.

Objective: The aim of this study was to detect the frequency of methicillin-resistant Staphylococcus aureus (MRSA) colonization at admission in a group of presumably high-risk international or Turkish patients referred to our center for elective operations, some of whom were from countries with an unknown prevalence of MRSA infection or colonization.

Methods: The results of nasal swab screening for MRSA colonization performed using a specific algorithm between 2011 and 2018 in a private medical center were retrospectively reviewed. Presence of MRSA was ascertained using culture and/or real-time polymerase chain reaction (real-time PCR).

[Results of a multicenter study investigating plasmid mediated colistin resistance genes (mcr-1 and mcr-2) in clinical Enterobacteriaceae ısolates from Turkey].

Colistin is a polymyxin antibiotic which is considered as one of the last line agents against infections due to multidrug resistant or carbapenem resistant gram-negative pathogens. Colistin resistance is associated with chromosomal alterations which can usually cause mutations in genes coding specific two component regulator systems. The first plasmid-mediated colistin resistance gene, mcr-1 was described in Escherichia coli and Klebsiella pneumoniae isolates in December 2015 and followed by another plasmid-mediated colistin resistance gene mcr-2 in 2016.

In vitro activities of colistin, tigecycline and tobramycin, alone or in combination, against carbapenem-resistant Enterobacteriaceae strains.

The aim of this study was to investigate the activities of various antibiotics, alone or in combination, against carbapenem-resistant Enterobacteriaceae (CRE). Minimum inhibitory concentrations (MICs) of meropenem, colistin, tigecycline and tobramycin were determined by microbroth dilution against 40 clinical strains. Carbapenemase-encoding genes were detected by PCR using specific primers.

The mgrB gene as a key target for acquired resistance to colistin in Klebsiella pneumoniae.

Objectives: Alterations in the PhoPQ two-component regulatory system may be associated with colistin resistance in Klebsiella pneumoniae. MgrB is a small transmembrane protein produced upon activation of the PhoPQ signalling system, and acts as a negative regulator on this system. We investigated the role of the MgrB protein as a source of colistin resistance in a series of K.

Trial of garlic as an adjunct therapy for multidrug resistant Pseudomonas aeruginosa pneumonia in a critically ill infant.

We present a case of a critically ill infant with severe multidrug-resistant Pseudomonas aeruginosa pneumonia and bacteremia who was treated with garlic and antibiotics after in vitro demonstration of a change in the resistance pattern via the disc diffusion method on garlic-treated Mueller Hinton agar. To our knowledge, this is the first report of therapeutic garlic use in a critically ill infant in the literature.

[Detection of human bocavirus DNA by polymerase chain reaction in children and adults with acute respiratory tract infections].

Human bocavirus (HBoV) which was described in 2005 by molecular techniques, is a member of Parvoviridae. The role of HBoV is being questioned in acute respiratory diseases (ARD) in many recent studies. The aim of this study was to determine the presence of HBoV DNA in the respiratory specimens of patients with ARD.

Serologic response to Epstein-Barr virus antigens in patients with systemic lupus erythematosus: a controlled study.

Previous studies showed a link between systemic lupus erythematosus (SLE) and Epstein-Barr virus (EBV) infection. We sought to determine the features of serologic response to EBV in SLE patients and whether this response differs from those of systemic sclerosis (SSc) and primary antiphospholipid syndrome (PAPS) patients as well as healthy individuals. Sera from 198 consecutive SLE patients have been tested to detect IgG antibodies to EA/D, EBNA-1, VCA P18 and for comparison, cytomegalovirus (CMV) using commercially available ELISA kits (Trinity Biotech, USA).

High occurrence of cyclosporiasis in Istanbul, Turkey, during a dry and warm summer.

We evaluated the incidence of Cyclospora cayetanensis in immunocompetent, diarrheic patients during the summers of 2006-2009 in Istanbul. Stools from 1876 patients were examined using microscopic techniques. Cyclospora oocysts were observed in wet preparations by light and epifluorescence microscopy and in fecal smears that were stained by Kinyoun's modified acid-fast stain.

Acute prostatitis as an uncommon presentation of brucellosis.

The present report concerns a 46-year-old man who presented with acute prostatitis due to Brucella melitensis infection. He was first treated with doxycycline and ciprofloxacin, but after 3 months he was admitted again with the same diagnosis. The relapse was probably related to ciprofloxacin use, or the length of treatment not being sufficient.
