Bartonellae are zoonotic pathogens with a broad range of reservoir hosts and vectors. To examine sylvatic reservoirs, tissue samples of red deer (, = 114) and their associated deer keds (, = 50; , = 272) collected in the Czech Republic were tested for the presence of using PCR at four loci (, , , ITS); PCR sensitivity was increased significantly by using primers modified for the detection of wildlife-associated bartonellae. One-third of the deer and 70% of the deer keds were positive; within the tested animal tissues, usually the spleen was positive.

Recently a resurgence of has arisen, with concerns around the highly virulent M1 lineage. Our aim was to characterize , the immune responses it causes, and to determine the presence of the M1 lineage in Sofia, Bulgaria. In our study, the infections were confirmed by culture testing or rapid antigen test.

Island habitats provide unique opportunities to study speciation. Recent work indicates that both ex situ origination and in situ speciation contribute to island species diversity. However, clear evidence of local adaptation of endemic plant species on islands requires in-depth studies, which are scarce.

Although genome-scale analyses have provided insights into the connection between genetic variability and complex human phenotypes, much trait variation is still not fully understood. Genetic variation within repetitive elements, such as the multi-copy, multi-locus ribosomal DNA (rDNA), has emerged as a potential contributor to trait variation. Whereas rDNA was long believed to be largely uniform within a species, recent studies have revealed substantial variability in the locus, both within and across individuals.
