| lawsonia intracellularis-like organism infection in a miniature foal. | a 7-month-old foal was admitted to the hospital with a history of lethargy, weight loss, mild diarrhea, and anorexia. a diagnosis of proliferative enteritis caused by lawsonia intracellularis-like organisms was made after necropsy and histologic examination of the small intestine. although infection with l intracellularis-like organisms is a rare cause of enteritis in foals, it should be considered in the differential diagnosis, especially if the foal was housed in the proximity of pigs or pig f ... | 1999 | 10461636 |
| protein-losing enteropathy caused by lawsonia intracellularis in a weanling foal. | a 5-month-old morgan filly was presented to the atlantic veterinary college with a history of lethargy, fever, depression, anorexia, and dependent ventral edema. diagnostic tests revealed severe inflammation, hypoproteinemia, and thickened small intestinal loops. protein-losing enteropathy caused by lawsonia intracellularis was diagnosed and treated successfully with erythromycin-rifampin. | 2003 | 12619560 |
| lawsonia intracellularis proliferative enteropathy in a filly. | proliferative enteropathy (pe) caused by the obligate intracellular bacterium lawsonia intracellularis is a disease of high economic impact in swine worldwide. in most other species the disease occurs as a sporadic infection. this paper reports a pe caused by l. intracellularis in a 9-month-old pura raza española filly with a history of profuse diarrhoea. pathological lesions consisted of a severe proliferative enteritis associated with argyrophilic bacteria in the apical cytoplasm of proliferat ... | 2006 | 16411902 |
| an outbreak of lawsonia intracellularis infection in a standardbred herd in ontario. | an outbreak of protein-losing enteropathy associated with lawsonia intracelluaris infection was diagnosed in 6 standardbred foals from a farm in ontario. wildlife exposure may have been involved in the perpetuation of disease in this outbreak. the clinical presentation, treatment, outcomes, and pathological findings are described. | 2007 | 17966333 |

| lawsonia intracellularis infection in horses: 2005-2007. | lawsonia intracellularis is an emerging equine pathogen that is a cause of equine proliferative enteropathy (epe). | 2008 | 18681919 |
| the seroprevalence of lawsonia intracellularis in horses in the netherlands. | equine proliferative enteropathy caused by lawsonia intracellularis is an emerging disease of weanling foals and affects their growth and development. the prevalence of lawsonia intracellularis in the netherlands is not known. the aim of the study was to investigate the seroprevalence of lawsonia intracellularis in horses in the netherlands. blood samples were taken from healthy foals before and after weaning and from healthy yearlings and mature horses on farms throughout the netherlands. these ... | 2011 | 21528618 |
| serial use of serologic assays and fecal pcr assays to aid in identification of subclinical lawsonia intracellularis infection for targeted treatment of thoroughbred foals and weanlings. | objective-to assess the serial use of serum immunoperoxidase monolayer assays (ipmas) and fecal pcr assays, combined with other diagnostic methods, to identify subclinical lawsonia intracellularis infections for targeted treatment of thoroughbred foals and weanlings at farms in which the pathogen was endemic or nonendemic. design-evaluation study. animals-100 foals and weanlings (53 and 47 at farms in which l intracellularis was endemic and nonendemic, respectively). procedures-serum was collect ... | 2011 | 21627513 |
| lawsonia intracellularis-specific interferon +¦ gene expression by peripheral blood mononuclear cells in vaccinated and naturally infected foals. | the cell-mediated immune response to lawsonia intracellularis, the agent of equine proliferative enteropathy (epe), was investigated in vaccinated and naturally infected foals. interferon (ifn)-+¦ gene expression was determined in peripheral blood mononuclear cells collected from vaccinated (n=6) and control foals (n=6) every 30days for 180days following first vaccine administration, and from clinically affected foals (n=16) within 7-10days of diagnosing epe. seroconversion (immunoperoxidase mon ... | 2011 | 21689957 |
| a follow up study on antibodies against lawsonia intracellularis in mares and foals from two breeding farms in germany. | equine proliferative enteropathy (epe) caused by lawsonia (l.) intracellularis is an emerging disease in foals, particularly in north america. since a case report in germany exists, the objective of this study was to examine the incidence of l. intracellularis-antibodies in healthy horses from two german breeding farms. in group 1, serum samples from 24 (year 1) and 16 (year 2) haflinger mares and their foals were taken. in group 2, over a period of five months, serum samples of six warmblood ma ... | 2011 | 21848042 |
| lawsonia intracellularis-associated proliferative enteritis in weanling foals in the netherlands. | equine proliferative enteropathy (epe) is an emerging infectious enteric disease caused by the obligate intracellular gram-negative bacterium lawsonia intracellularis. epe was tentatively diagnosed in six weanling foals, aged between 5 and 7 months. clinical signs included depression, anorexia, ventral oedema, and weight loss. plasma biochemistry consistently revealed severe hypoproteinaemia. the ante-mortem diagnosis of epe was based on clinical signs, hypoproteinaemia (6/6), the detection of m ... | 2011 | 22111417 |
