Background: Potato virus Y (PVY) is among the economically most damaging viral pathogen in production of potato (Solanum tuberosum) worldwide. The gene Ry derived from the wild potato relative Solanum stoloniferum confers extreme resistance to PVY.

Results: The presence and diversity of Ry were investigated in wild relatives of potato (298 genotypes representing 29 accessions of 26 tuber-bearing Solanum species) using PacBio amplicon sequencing.

Using late blight resistance genes targeting conservative effectors of Phytophthora infestans and the constructing gene pyramids may lead to durable, broad-spectrum resistance, which could be accelerated through genetic engineering. Potato (Solanum tuberosum L.) is one of the most important food crops worldwide.

Acinetobacter baumannii is a major cause of nosocomial infections worldwide. Therapeutic options in management of this bacteria are limited. Tigecycline is considered as an alternative treatment of infections caused by multidrug-resistant A.

Background: Over the last decades, Candida species have emerged as important pathogens in immunocompromised patients. Nosocomial infections are mainly of endogenous origin. Nevertheless, some cases of exogenous candidiasis have also been reported.

Almost as soon as antibiotics were introduced to treat infectious diseases, it could be observed that bacteria were able to develop resistance against them. Currently, multidrug-resistant strains are being isolated mainly in the hospital environment. These are primarily non-fermenting Gram-negative bacilli, which exhibit both natural and acquired resistance to multiple antibiotics and disinfectants rendering them difficult to eradicate.

Acinetobacter baumannii is a Gram-negative, glucose-non-fermenting, oxidase-negative coccobacillus, most commonly associated with the hospital settings. The ability to survive in adverse environmental conditions as well as high level of natural and acquired antimicrobial resistance make A. baumannii one of the most important nosocomial pathogens.

Over the last decades, Candida spp have been responsible for an increasing number of infections, especially in patients requiring intensive care. Knowledge of local epidemiology and analysis of the spread of these pathogens is important in understanding and controlling their transmission. The aim of this study was to evaluate the genetic diversity of 31 Candida albicans and 17 Candida glabrata isolates recovered from intensive care unit patients from the tertiary hospital in Krakow between 2011-2012.

Background: Acinetobacter baumannii is a significant hospital pathogen, possessing a considerable degree of antimicrobial resistance. A. baumannii resistance to carbapenems and aminoglycosides is mostly conferred by class D OXA carbapenemases and aminoglycoside-modifying enzymes, respectively.

Acinetobacter baumannii is an important nosocomial pathogen occurring particularly in intensive care (ICU) as well as burn therapy units (BTU). A. baumannii strains have emerged as resistant to almost all antimicrobial agents, including carbapenems.

Introduction: Multidrug-resistant gram-negative non-fermenting bacilli are an important cause of nosocomial infection. Aim of this study was to analyze the prevalence and antimicrobial susceptibility of rods of the species Acinetobacter baumannii and Pseudomonas aeruginosa, belonging to multidrug-resistant alert pathogens.

Methods: 105 (70%) strains of A.

Introduction: Gram-negative bacteria belonging to the family Enterobacteriaceae cause severe and difficult to treat nosocomial infections. Strains of different species that produce extended-spectrum beta-lactamases (ESBL) were classified as alert pathogens. The purpose of this study was to analyze the occurrence and determination of antimicrobial susceptibility patterns of 134 ESBL-producing Enterobacteriaceae strains.

The aim of study was to recognize the epidemiology of hospital acquired pneumonia on the base of genotypes of Acinetobacter baumannii and Pseudomonas aeruginosa strains. Gram negative-non fermenting bacilli are the most frequent aetiologic agent of hospital acquired pneumonia among patients from Anesthesiology and Intensive Care Unit in the Rydygiers hospital in Cracow. In the following research RAPD-PCR method was applied and there 272, 208, ERIC- 2 and PAL- 2 primers were used.
