In this study, we isolated and characterized three phages named as Salmacey1, Salmacey2 and Salmacey3, infecting multi drug resistant Salmonella serovars isolated from broilers in Egypt. The most prevalent Salmonella serovars were S. typhimurium, S. enteritidis, and S. kentucky. All these Salmonella serovars were found to be resistant to more than two of the ten antimicrobial agents tested. Only S. kentucky was found to be resistant to seven antimicrobial agents. Examination of these phage particles by transmission electron microscopy (TEM), demonstrated that two phages (Salmacey1, Salmacey2) were found to belong to family Siphoviridae, and Salmacey3 was assigned to the family Myoviridae...

Three carbapenem-resistant clinical isolates of the Enterobacter cloacae complex (ECC) were recovered from different patients in a hospital. All 3 isolates carried 2 carbapenemase genes blaKPC-2 and blaNDM-1. A study was performed to characterize their relatedness and to investigate possible links among the patients. Whole genome sequencing revealed that the isolates were Enterobacter hormaechei and belonged to ST177 of the ECC. There were 19-142 single nucleotide polymorphisms (SNPs) between the isolates, suggesting that the isolates were likely from a central reservoir, which might have existed for some time...

Background: Colistin is the last drug option for the treatment of MDR Gram-negative bacterial infections. Several types of resistance to colistin have been identified, including hetero-resistance, which has been observed in several Gram-negative pathogens. During a routine surveillance project on antimicrobial resistance, we found abnormal colistin-resistant Enterobacter asburiae and Enterobacter cloacae isolates. E. cloacae is an intestinal commensal bacterium and a well-known opportunistic nosocomial pathogen...

Although the European reports highlight an increase in community-acquired Legionnaires' disease cases, the risk of Legionella spp. in private houses is underestimated. In Pisa (Italy) we performed a three-year survey on Legionella presence in 121 buildings with an independent hot water production (IB); 64 buildings with a central hot water production (CB); and 35 buildings with a solar thermal system for hot water production (TB). From all the 220 buildings Legionella spp. was researched in two hot water samples collected either at the recirculation point or on the first floor and on the last floor, while the potable water quality was analysed in three cold water samples collected at the inlet from the aqueduct network, at the exit from the autoclave, and at the most remote tap...

Health care of severe burn patients is highly specialized and may require international patient transfer. Burn patients have an increased risk of developing infections. Patients that have been hospitalized in countries where carbapenemase-producing microorganisms (CPMO) are endemic may develop infections that are difficult to treat. In addition, there is a risk on outbreaks with CPMOs in burn centers. This study underlines that burn patients may extensively be colonized with CPMOs, and it provides best practice recommendations regarding clinical microbiology and infection control...

The classic presentation of acute gastrointestinal (GI) parasitic infection including fever, diarrhea, nausea, and/or abdominal pain is not always a reliable measure. In these cases, parasitic infections require sensitive stool testing to be identified and treated effectively. The standard practice for stool analysis typically requires 3 separate stool specimens to be collected on 3 separate days to overcome the possibility of misdiagnosis due to intermittent shedding. Nonetheless, this practice is not often utilized due to very short periods of sample viability, which often leads to patient misdiagnosis...

The ongoing Libyan conflict constantly causes victims among the military and civilian population. Cross-border transfer of patients represents a high risk of introducing multidrug-resistant organisms (MDROs), for example, methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci, and carbapenem-resistant gram-negative organisms (CROs), into the country of destination. This study assessed the MDRO status in Libyan war casualties (n = 67) admitted to Northwest Medical Centre in Frankfurt/Main, Germany, from August 2016 till January 2017...
