Specifically, A. equuli is known to cause neonatal sepsis in foals, known as Sleepy Foal Disease. (wikipedia.org)
Of these diseases, epididymitis and orchitis in rams (caused by A. seminis ), sleepy foal disease (caused by A. equuli ), porcine pleuropneumonia (caused by A. pleuropneumoniae ) and pyogranulomatous lesions of the soft tissues of the head - in particular the oral cavity or the forestomachs of cattle, sheep and goats - (caused by A. lignieresii) occur most commonly. (anipedia.org)
equuli is the etiological agent of sleepy foal disease, an acute form of fatal septicemia in newborn foals. (bvsalud.org)
Haemolyticus4
haemolyticus results in similar pathogenesis as A. equuli subsp. (wikipedia.org)
Isolation of the subspecies equuli have been found in both horses and pigs, but only subspecies haemolyticus has been isolated from horses. (wikipedia.org)
A. equuli subspecies haemolyticus contain strains: T 355/87, F 92, Ac 7 F 119, F 154T, and F 490. (wikipedia.org)
Isolates previously described as A. suis but isolated from horses, are now known as Actinobacillus equuli subspecies haemolyticus . (anipedia.org)
Subspecies7
Actinobacillus equuli subspecies equuli is not hemolytic and is found in equine and porcine hosts. (wikipedia.org)
It was previously thought that this bacteria was limited to the species level, however it is now divided into two subspecies of Actinobacillus equuli which include: A. equuli subsp. (wikipedia.org)
The 16S rRNA gene for A. equuli is AF381186, this helps classification of the bacteria to the species level but not to the subspecies level. (wikipedia.org)
Isolation of the subspecies equuli in the UK and Australia determined that it contained strains NCTC 8529T, and I 5445/4. (wikipedia.org)
PCR testing that results in the presence of the RTX gene allows differentiation to be made between the two subspecies, as only A. equuli subsp. (wikipedia.org)
Lignieresii2
Another 16s rRNA study determined that an A. equuli type strain was 98.3% similar to A. lignieresii but are of different species. (wikipedia.org)
Actinobacillus equuli, A. lignieresii, A. rossii and A. suis grow readily on ordinary bacterial growth media. (anipedia.org)
A. equuli is commonly found in the mucous membranes of healthy horses' respiratory and alimentary tracts and rarely causes disease in adult horses. (bvsalud.org)
Foals4
A. equuli can commonly be isolated from the upper respiratory tract and oral cavity of adult healthy horses and can be important for diseases of foals, adult horses and pigs. (wikipedia.org)
Despite it being a component of the normal flora, an mean isolation frequency as low as 37% (n =174) in adult horses and foals was detected in one study. (wikipedia.org)
It is important to note that A. equuli does not only cause sleepy foal syndrome in foals, it is also a causative agent of pneumonia, muscular degeneration and jaundice in foals. (wikipedia.org)
Important risk factors for foals acquiring an infection with A. equuli include failure of passive transfer, unsanitary foaling environments, and the presence of immunosuppressive conditions. (wikipedia.org)
Occasionally, humans can become infected with A. equuli, more commonly as a result from destruction to the skin barrier, such as a horse bite. (wikipedia.org)
Less commonly, A. equuli will cause disease in adult horses, resulting in respiratory infections. (wikipedia.org)
Characteristic2
The characteristic of being L-arabinose positive was thought to be an important taxonomic characteristic to classify A. equuli strains from others. (wikipedia.org)
This characteristic is most marked in A. equuli, 14 but it may be lost on repeated subculture. (anipedia.org)
Septicemia1
A. equuli also has the capability to cause kidney damage, arthritis and septicemia in affected pigs. (wikipedia.org)
Pleuropneumonia1
The gross and histopathological examinations revealed a unilateral fibrinosuppurative and hemorrhagic pleuropneumonia with an infrequent parenchymal distribution and heavy isolation of A. equuli. (bvsalud.org)
Bacteria1
Actinobacillus equuli is a gram-negative, non-motile rod bacteria from the family Pasteurellaceae. (wikipedia.org)
Diseases2
Due to these diseases and conditions, A. equuli can result in great economic losses especially in the equine industry. (wikipedia.org)
A. equuli is the causative agent in sleepy foal syndrome, which has been documented throughout the world. (wikipedia.org)
Positive1
An important aspect of the isolation frequency is that a horse or foal will not be culture positive every time it is swabbed, making it hard to determine the correct isolation frequency. (wikipedia.org)
