Bovine mastitis caused by streptococcus uberis. Virulence factors and biofilm
(OMICS International, 2017-12)
Bovine mastitis is a multifactorial disease, commonly caused by microorganisms. The pathology affects dairy farms worldwide and causes significant economic losses. Different pathogens can cause the disease and they are ...
Understanding the Detection of Shiga Toxin Producing Escherichia Coli: Virulence Factors, Pathogenicity Islands or Serotypes?
(Biomedical Research Network, 2018-03)
Shiga toxin-producing Escherichia coli (STEC) are important food borne pathogens that can cause severe disease in children by producingtwo toxins (Stx1 and Stx2). This bacteria harbor several additional virulence factorsand ...
Exopolyphosphatase of Pseudomonas aeruginosa is essential for the production of virulence factors, and its expression is controlled by NtrC and PhoB acting at two interspaced promoters
(Society for General Microbiology, 2014-01)
The exopolyphosphatase (Ppx) of Pseudomonas aeruginosa is encoded by the PA5241 gene (ppx). Ppx catalyses the hydrolysis of inorganic polyphosphates to orthophosphate (Pi). In the present work, we identified and characterized ...
Virulence profile comparison between LEE-negative Shiga toxin-producing Escherichia coli (STEC) strains isolated from cattle and humans
(Elsevier Science, 2010-07)
For comparison purposes, the prevalence of 8 virulence markers was investigated, by PCR, in 153 cattle and 47 human Locus for Enterocyte Effacement (LEE)-negative Shiga toxin-producing Escherichia coli (STEC) strains ...
Virulence factors of the Mycobacterium tuberculosis complex
(Taylor & Francis, 2013-01)
The Mycobacterium tuberculosis complex (MTBC) consists of closely related species that cause tuberculosis in both humans and animals. This illness, still today, remains to be one of the leading causes of morbidity and ...
High-Temperature Protein G Is an Essential Virulence Factor of Leptospira interrogans
(American Society for Microbiology, 2014-03)
Leptospira interrogans is a global zoonotic pathogen and is the causative agent of leptospirosis, an endemic disease of humans and animals worldwide. There is limited understanding of leptospiral pathogenesis and further ...
Effectiveness of several nutritional sources on the virulence of Beauveria bassiana s.l. CEP147 against the planthopper Delphacodes kuscheli
(Wiley Blackwell Publishing, Inc, 2022-02)
Delphacodes kuscheli Fennah (Hemiptera: Delphacidae) is the main planthopper vector of Mal de Río Cuarto virus (MRCV), a Fijivirus that severely affects maize production in Argentina. The effect of several nutritional ...
Traceability of potential enterotoxigenic Bacillus cereus in bee-pollen samples from Argentina throughout the production process
(Elsevier Science, 2020-12)
Bee-pollen is a functional food sold for human and animal consumption but also is a favorable microhabitat for many spore-forming bacteria. Among them, Bacillus cereus can produce several toxins and other virulence factors, ...
Stenotrophomonas maltophilia isolated from patients exposed to invasive devices in a university hospital in Argentina: Molecular typing, susceptibility and detection of potential virulence factors
(Society for General Microbiology, 2018-07)
Purpose. The aim of this work was to investigate the presence of selected potential virulence factors, susceptibility and clonal relatedness among 63 Stenotrophomonas maltophilia isolates recovered from patients exposed ...
The effect of Zuccagnia punctata, an argentine medicinal plant, on virulence factors from Candida species
(Natural Products, 2014-07)
Zuccagnia punctata Cav. has been used as a traditional medicine in Argentina for the treatment of bacterial and fungal infections. In this study, we evaluated the ability of Z. punctata extracts (ZpE) and isolated compounds ...
