Background The intestinal microbiota contributes to the colonization resistance of gut towards bacterial pathogens. Antibiotic treatment often negatively affects microbiome composition, rendering host more susceptible for infections. However, a correct interpretation such perturbation requires quantitative profiling reflect accurately direction and magnitude compositional changes within microbiota. Standard 16S rRNA gene amplicon sequencing samples offers data in relative, but not absolute...
Chlamydia psittaci is the etiological agent of chlamydiosis in birds and can be transmitted to humans, causing severe systemic disease. C. infects a broad range hosts; strains are isolated not only from but also mammals, where they seem have reduced infectious zoonotic potential. Comparative analysis chlamydial genomes revealed coding sequences polymorphic membrane proteins (Pmps) highly variable regions. Pmps characterized as adhesins trachomatis pneumoniae immunoreactive several species....
Analysis of volatile organic compounds (VOCs) is a novel approach to accelerate bacterial culture diagnostics Mycobacterium avium subsp. paratuberculosis (MAP). In the present study, cultures fecal and tissue samples from MAP-infected non-suspect dairy cattle goats were explored elucidate effects sample matrix animal species on VOC emissions during cultivation identify early markers for growth. The processed following standard laboratory procedures, tubes incubated different time periods....
Cattle harbor Shiga toxin-producing Escherichia coli (STEC) in their intestinal tract, thereby providing these microorganisms with an ecological niche, but without this colonization leading to any clinical signs. In a preceding study, genotypic characterization of bovine STEC isolates unveiled that ability colonize cattle persistently (STECper) or only sporadically (STECspo) is more closely associated the overall composition accessory rather than core genome. However, pattern could not be...
Field experiments were conducted at two locations in Missouri 2012 and 2013 to evaluate herbicide programs 4-hydroxyphenylpyruvate dioxygenase (HPPD)-inhibitor-resistant soybean, referred as FG72 their tolerance four HPPD-inhibiting herbicides. At the Columbia location, PRE followed by (fb) POST two-pass treatments provided 97% or greater control of all weeds except ivyleaf morningglory.

South American camelids (SAC) are increasingly kept in Europe close contact with humans and other livestock species can potentially contribute to transmission chains of epizootic, zoonotic antimicrobial-resistant (AMR) agents from humans. Consequently, SAC were included as the new European Animal Health Law. However, knowledge on bacteria exhibiting AMR is too scarce draft appropriate monitoring preventive programs. During a survey holdings central Germany, 39 Escherichia coli strains...
Paratuberculosis is an important disease of ruminants caused by Mycobacterium avium ssp. paratuberculosis (MAP). Early detection crucial for successful infection control, but available diagnostic tests are still dissatisfying. Methods allowing a rapid, economic, and reliable identification animals or herds affected MAP urgently required. This explorative study evaluated the potential volatile organic compounds (VOCs) to discriminate between cattle with without infections. Headspaces above...
Analysis of volatile organic compounds (VOC) derived from bacterial metabolism during cultivation is considered an innovative approach to accelerate in vitro detection slowly growing bacteria. This applies also Mycobacterium avium subsp. paratuberculosis (MAP), the causative agent paratuberculosis, a debilitating chronic enteritis ruminants. Diagnostic application demands robust VOC profiles that are reproducible under variable culture conditions. In this study, patterns pure cultures, three...
Mycoplasmopsis (M.) bovis, the agent of mastitis, pneumonia, and arthritis in cattle, harbors a small genome approximately 1 Mbp. Combining data from Illumina Nanopore technologies, we sequenced assembled genomes 35 European strains isolate DL422_88 Cuba. While high proportion repetitive structures M. bovis represent particular challenge, implementation our own pipeline Mycovista (available on GitHub www.github.com/sandraTriebel/mycovista ) hybrid approach enabled contiguous assembly and,...
Contagious caprine pleuropneumonia (CCPP) is a fatal WOAH-listed, respiratory disease in small ruminants with goats as primary hosts that caused by Mycoplasma capricolum subspecies capripneumoniae (Mccp). Twelve CCPP outbreaks were investigated 11 goat herds and herd of captive Arabian sand gazelle (Gazella marica) four Omani governorates clinical pathological molecular analysis to compare manifestation Mccp genetic profiles wild ungulates.
Abstract Background CERTUS Environmental Listeria species Detection Kit (CERTUS EL Kit) is a real-time, bio-contained assay designed to accurately detect (L. grayi, L. innocua, ivanovii, marthii, monocytogenes, seeligeri, and welshimeri) from environmental surface matrixes using an antibody-coupled magnetic microparticle with Surface Enhanced Raman Spectroscopy (SERS) nanoparticle technology test system paired proprietary Selective Growth Media Unit. Objective The method was evaluated for...
