BACKGROUND Although the majority of bacteria are innocuous or even beneficial for their host, others are highly infectious pathogens that can cause widespread and deadly diseases. When investigating the relationships between bacteria and other living organisms, it is therefore essential to be able to separate pathogenic organisms from non-pathogenic ones. Using traditional experimental methods ...

To evaluate the pathogenicity of staphylococci from bovine raw milk, the general characteristics of 775 strains isolated from 798 samples of milk were studied. The coagulase test was performed by use of rabbit plasma. Chromogenesis, mannitol fermentation, and gelatin liquefaction were investigated on Chapman's Medium 110, after 48 hr of incubation. Production of beta-hemolysin, which has been c...

Myzus persicae is an economically important pest infecting more than 40 families of crops throughout the world. Six entomopathogenic fungal isolates, three each of Beauveria bassiana and Verticillium lecanii, were screened for pathogenicity test against the M. persicae to select high virulent isolate with the most suitable application and to determine the role of individual enzyme in its virule...

background and objectives: enteropathogenic escherichia coli (epec) strains can be detected by serogrouping and the presence of enterocyte attaching- effacing (eae) gene. most epec strains belong to a certain o antigenic group. locus of enterocyte effacement (lee) pathogenicity island contains the eae gene and secretory proteins (esps) that introduce the attaching-effacing lesion. lee inserted ...

Reports of sooty bark disease maples caused by the fungus Cryptostroma corticale have recently been emerging from across Europe. The aims our study were to describe first report in Slovenia, determine pathogenicity C. corticale, confirm optimum temperature for growth fungus, and mass loss Acer pseudoplatanus wood inoculated corticale. We confirmed presence on A. via morphological molecular anal...

Background Lyme borreliosis (LB) is multisystem infectious disease with various clinical manifestations. In Europe, LB is caused by gram-negative spirochetal bacteria of the complex Borrelia burgdorferi sensu lato. The most important for human pathogenicity are B. garinii, B. afzelii and B.burgdorferi sensu stricto. Indirect laboratory diagnostics of LB is based on serological methods such as E...

Yellowing disease has become one of the main threats to black pepper (Piper nigrum L.) production. This study was conducted isolate and characterize Fusarium species associated with yellowing based on morphological molecular characteristics, evaluate their pathogenicity pepper. Fungal isolates were recovered from symptomatic plants located in major growing areas Sarawak. Based a total 73 identi...
