“…The most typical clinical symptom of overt infection with T. pyogenes for all technological groups is the presence of abscesses in the subcutaneous tissue, organs or within muscles, which are only observable posthumously or during a post-mortem examination (Brinton et al 1993, Lawson et al 2001, Ertas et al 2005, Jost et al 2005, Ide et al 2006, Moore et al 2010, Ü lbegi-Mohyla et al 2010, Shahbazfar et al 2013. A factor that contributes to the development of purulent lesions is the production by T. pyogenes of pyolysine and serine protease.…”

Trueperella pyogenes is an opportunistic pathogen causing purulent infections in pigs and other animal species. T. pyogenes infections in pigs are local and/or generalized depending on the immune status of the animals, their individual susceptibility and environmental factors. The occurrence of these infections on pig farms causes substantial economic losses in breeding and rearing. In sows from the breeding herd, the disease leads to infertility, embryonic death, abortion, and disorders of the menstrual cycle and lactation. Mastitis is the major cause of losses in piglets. Disorders of the musculoskeletal system, including inflammatory polyarthritis, fractures and degenerative joint disease results in the culling of animals with high breeding value. In other technological groups, multi-organ inflammations and movement disorders dominate, leading to a reduction of the slaughter value and elimination of pigs from breeding. Understanding of the clinical and pathological aspects of T. pyogenes infections in pigs will enable the development of effective methods of combating this disease on pig farms.

Epethelial Presence of Trueperella pyogenes Predicts Site-Level Presence of Cranial Abscess Disease in White-Tailed Deer (Odocoileus virginianus)

et al. 2015

Cranial/intracranial abscess disease is an emerging source of significant mortality for male white-tailed deer (Odocoileus virginianus). Most cases of cranial/intracranial abscess disease are associated with infection by the opportunistic pathogen Trueperella pyogenes although the relationship between the prevalence of the bacteria and occurrence of disease is speculative. We examined 5,612 hunter-harvested deer from 29 sites across all physiographic provinces in Georgia for evidence of cranial abscess disease and sampled the forehead, lingual, and nasal surfaces from 692 deer. We used polymerase chain reaction (PCR) to determine presence of T. pyogenes from these samples. We found T. pyogenes prevalence at a site was a predictor for the occurrence of cranial abscess disease. Prevalence of T. pyogenes did not differ between samples from the nose or tongue although prevalence along the forehead was greater for males than females (p = 0.04), particularly at sites with high occurrence of this disease. Socio-sexual behaviors, bacterial prevalence, or physiological characteristics may predispose male deer to intracranial/cranial abscess disease. Determination of factors that affect T. pyogenes prevalence among sites may help explain the occurrence of this disease among populations.

“…Trueperella (Arcanobacterium) pyogenes (Yassin et al 2011), a resident bacterium on mucosal membranes and skin of healthy animals (Moore et al 2010), has been isolated from 65 of the 100 published cases of intracranial abscesses from white-tailed deer in which culture was attempted (Davidson et al 1990;Baumann et al 2001;Nettles et al 2002). Trueperella pyogenes may be the most widely distributed and most common opportunistic pathogen of mucosal surfaces in domestic animals (Jost and Billington 2005;Moore et al 2010) and is commonly found along the digestive tract, udders, urogenital region, and upper respiratory tracts of healthy animals (Natterman and Horsch 1977; Queen et al 1994;Narayanan et al 1998;Jost et al 2002).…”

ABSTRACT:Intracranial abscess disease is a cause of natural mortality for mature male whitetailed deer (Odocoileus virginianus). Most cases of abscesses are associated with bacterial infection by Trueperella (Arcanobacterium) pyogenes, but a complete understanding of the epidemiology of this disease is lacking. We quantified the effects of individual characteristics, site-specific herd demographics, land cover, and soil variables in estimating the probability of this disease. We examined 7,545 white-tailed deer from 60 sites throughout Georgia, US for signs of cranial abscesses, the predecessor of intracranial abscesses, and recorded the presence or absence of cranial abscesses for each individual examined. We detected no cranial abscesses in 2,562 female deer but 91 abscesses in 4,983 male deer examined (1.8%). A generalized linear mixed model, treating site as a random effect, was used to examine several potential explanatory risk factors including site-level landscape and soil characteristics (soil and forest type), demographic factors (deer density and male to female ratio), and individual host factors (deer sex and age). Model results indicated that the probability of a male having a cranial abscess increased with age and that adult sex ratio (male:female) was positively associated with this disease. Site-specific variables for land cover and soil types were not strongly associated with observations of the disease at the scale measured and a large amount of among-site variability remained. Given the demonstrated effect of age, gender, and local sex ratios but the remaining unexplained spatial variability, additional investigation into spatiotemporal variation of the presumed bacterial causative agent of cranial abscesses appears warranted.
