The M-protein genes of Streptococcus equi isolated from 17 outwardly healthy horses after 4 strangles outbreaks had ended, including a quarantined animal, were compared with those of S. equi isolates from 167 active cases of strangles across 4 countries. The healthy horses included 16 persistent S. equi carriers, at least one from each of the four outbreaks. These carriers, despite being outwar...
Quantitative aspects of fecal Rhodococcus (Corynebacterium) equi in newborn foals for 12 weeks after birth were investigated on two horse breeding farms. R. equi was found in the feces of foals during week 1 of life. The greatest numbers of R. equi were present in the feces of foals during the first 8 weeks of their lives, which coincides with the age when foals are most liable to be exposed to...
BACKGROUND Streptococcus equi subsp equi (S. equi) is the cause of "equine strangles" which is a highly infectious upper respiratory disease. Detection of S. equi is influenced by site of specimen collection, method of sampling, and type of diagnostic test that is performed. We hypothesized i) that a loop-mediated isothermal amplification (LAMP) assay that targets the S. equi-specific eqbE gene...
The continued evolution of bacterial pathogens has major implications for both human and animal disease, but the exchange of genetic material between host-restricted pathogens is rarely considered. Streptococcus equi subspecies equi (S. equi) is a host-restricted pathogen of horses that has evolved from the zoonotic pathogen Streptococcus equi subspecies zooepidemicus (S. zooepidemicus). These ...
We present two cases of Rhodococcus equi bacteremia as a cause of sepsis in premature infants who had increasing respiratory distress with multiple episodes of apnea. When we investigated these infants for apnea etiology, blood cultures were taken, and R. equi was confirmed based on the colony characteristics on nutrient agar; extended antibiotherapy was started. R. equi has been identified fre...
Streptococcus equi (Streptococcus equi subsp. equi), a Lancefield group C streptococcus, causes strangles, a highly contagious purulent lymphadenitis and pharyngitis of members of the family Equidae. The antiphagocytic 58-kDa M-like protein SeM is a major virulence factor and protective antigen. The amino acid sequence and structure of SeM has been determined and compared to that of a second, 4...
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...
Equi merozoite antigens 1 and 2 (EMA-1 and EMA-2) are Babesia equi proteins expressed on the parasite surface during infection in horses and are orthologues of proteins in Theileria spp., which are also tick-transmitted protozoal pathogens. We determined in this study whether EMA-1 and EMA-2 were expressed within the vector tick Boophilus microplus. B. equi transitions through multiple, morphol...
A subset D of ( ) V G is called an equitable dominating set if for every ( ) v V G D there exists a vertex u D such that ( ) uv E G and | ( ) ( ) | 1 deg u deg v . A subset D of ( ) V G is called an equitable independent set if for any , u D v ( ) e N u for all { } v D u . The concept of equi independent equitable domination is a combination of these two important concepts. ...
