A simple and portable assay for detection of Streptococcus equi subspecies equi has been developed based on amplification of S. equi-specific sequence using a thermophilic helicase-dependent reaction followed by visual detection of the amplicon in a disposable lateral flow cassette. An experimental kit (IsoAmp™ SE) was evaluated. Analytical sensitivity was 50 copies of S. equi genomic DNA per r...

Lannergård, J. 2006. Potentially Virulence-Related Extracellular Proteins of Streptococcus equi. Doctoral thesis. ISSN 1652-6880. ISBN 91-576-7129-X. Equine strangles, a disease of the upper respiratory tract caused by the bacterium Streptococcus equi subspecies equi, is one of the most commonly diagnosed and serious diseases in horses. However, the molecular basis of S. equi subsp. equi infect...

Equine babesiosis is a hemoprotozoan tickborne disease with worldwide distribution and caused by Theileria equi and Babesia caballi. This study was conducted to determine the seroprevalence of T. equi and B. caballi infection in Turkoman breed horses in North Khorasan Province of Iran. Blood samples were collected from 100 apparently healthy horses and examined by microscopy and indirect immuno...

This paper considers the following conjecture: If R is an unmixed, equidimensional local ring that is a homomorphic image of a Cohen-Macaulay local ring, then for any ideal J generated by a system of parameters, the Chern coefficient e1(J) < 0 is equivalent to R being non Cohen-Macaulay. The conjecture is established if R is a homomorphic image of a Gorenstein ring, and for all universally cate...

Equine piroplasmosis (EP) has not been considered indigenous in The Netherlands. However, following the detection of an apparently indigenous subclinical Babesia caballi infection in a horse on Schouwen-Duiveland (an island in the Zeeland Province), a survey was undertaken between May and September 2010 to assess the prevalence of the causative agents of EP in the South-West of The Netherlands....

The obligate parasitic bacterium Streptococcus equi subsp. equi is the causative agent of strangles, a serious disease of the upper respiratory tract in horses. In this study we have, using shotgun phage display, cloned from S. equi subsp. equi and characterized a gene, called sfs, encoding a protein termed SFS, representing a new type of fibronectin (Fn)-binding protein. The sfs gene was found...

Rhodococcus equi is an important etiologic agent of respiratory- and non-respiratory tract infections, diseases of animals and humans. Therapy includes the use of various group of chemotherapeutic agents, however resistance acquirement is quite common. To date there is no preferred treatment protocol for infections caused by isolates resistant to macrolides and rifampicin. The resistance acquir...

Streptococcus equi is the causative agent of the purulent infection equine strangles. This disease is transmitted through shedding of live bacteria from nasal secretions and abscess drainage or by contact with surfaces contaminated by the bacteria. Disinfectants are effective against S. equi, but inactivation by environmental factors, damage to equipment, and toxicity are of great concern. Bact...
