Emergence and Comparative Genome Analysis of Ohio Strains from Brown Rats, Poultry, and Swine in Hungary.

Rats are particularly important from an epidemiological point of view, because they are regarded as reservoirs for diverse zoonotic pathogens including enteric bacteria. This study is the first to report the emergence of serovar Ohio in brown rats () and food-producing animals in Hungary. We first reveal the genomic diversity of the strains and their phylogenomic relationships in the context of the international collection of .

Identification by High-Throughput Real-Time PCR of 30 Major Circulating Listeria monocytogenes Clonal Complexes in Europe.

Listeria monocytogenes is a ubiquitous bacterium that causes a foodborne illness, listeriosis. Most strains can be classified into major clonal complexes (CCs) that account for the majority of outbreaks and sporadic cases in Europe. In addition to the 20 CCs known to account for the majority of human and animal clinical cases, 10 CCs are frequently reported in food production, thereby posing a serious challenge for the agrifood industry.

[Rickettsia helvetica: an emerging tick-borne pathogen in Hungary and Europe].

Rickettsia helvetica belonging to spotted fever group rickettsiae was recently detected by polymerase chain reaction followed by sequencing in European sheep ticks (Ixodes ricinus) from Hungary. Current knowledge on these rickettsiae and the clinical and diagnostic aspects of R. helvetica infection is summarized.

[Babesia microti and Anaplasma phagocytophilum: two emerging zoonotic pathogens in Europe and Hungary].

Babesia microti and Anaplasma phagocytophilum was recently reported with a minimum prevalence of 0.9 and 1.3% in Hungary based on the PCR-sequencing analysis of 452 European sheep ticks (Ixodes ricinus).
