Background: There is limited literature on neonatal bacterial sepsis in New World (NW) camelids. Hypothesis: Bacterial culture-positive crias have clinical differences based on the specific bacterial genera isolated. Animals: Bacterial culture-positive NW camelid crias ,21 days of age from 1990 to 2005 were included. Methods: Historic physical examination and cliniopathologic data were retrieved from medical records as were the identity and antibiograms of bacterial isolates. Cases were categorized by outcome (survival versus nonsurvival) and type of sepsis (gram-negative or gram-positive). Kruskal-Wallis and chi-square testing were used to evaluate differences between groups.Results: Twenty-one crias met the inclusion criteria. Median age was 2 days. Failure of passive transfer was common. There were few differences identified on the basis of outcome or type of sepsis. Crias without gastrointestinal or central nervous system involvement survived in greater numbers. Forty-six percent of isolates were gram-positive. The most common isolates were the following: Escherichia coli, Enterococcus spp., Listeria monocytogenes, and Citrobacter spp. Overall survival was 67% (14/21).Conclusions and Clinical Importance: Crias with sepsis do not appear to present with major biochemical, hematologic, or blood gas abnormalities, potentially complicating diagnosis. Affected crias may not have localizing signs at presentation and are not usually febrile, although hypothermia, tachypnea, and tachycardia are relatively common. Total protein concentration was not a substitute for immunoglobulin G measurement in septic crias in this study. Familiarity with the clinical presentation and common pathogens isolated should improve early recognition and treatment and ultimately outcome of crias with sepsis.

“…Confirmation of REL has been based on the combination of these characteristic histopathological findings associated with immuno-histochemistry (Wilkins et al , 2000; Schwab et al , 2004; Ribeiro et al , 2006; Rissi et al , 2006), bacterial isolation (Yousif et al , 1984; McLaughlin et al , 1993; Johnson et al , 1995), serology (Börkü et al , 2006), and molecular biology (Wiedmann et al , 1997; Evans et al , 2004; Langohr et al , 2006; Bundrant et al , 2011). …”

Listeriosis is a disease primarily of ruminants caused by the Gram-positive bacterium Listeria monocytogenes. Ruminants either demonstrate manifestations of the encephalitic, septicemic, or reproductive form of listeriosis. The pathological and molecular findings with encephalitic listeriosis in a 5.5-month-old, male, mixed-breed goat and a 3-year-old Texel-crossed sheep from northern Paraná, Brazil are described. Clinically, the kid demonstrated circling, lateral protrusion of the tongue, head tilt, and convulsions; the ewe presented ataxia, motor incoordination, and lateral decumbency. Brainstem dysfunctions were diagnosed clinically and listeriosis was suspected. Necropsy performed on both animals did not reveal remarkable gross lesions; significant histopathological alterations were restricted to the brainstem (medulla oblongata; rhombencephalitis) and were characterized as meningoencephalitis that consisted of extensive mononuclear perivascular cuffings, neutrophilic and macrophagic microabscesses, and neuroparenchymal necrosis. PCR assay and direct sequencing, using genomic bacterial DNA derived from the brainstem of both animals, amplified the desired 174 base pairs length amplicon of the listeriolysin O gene of L. monocytogenes. Phylogenetic analyses demonstrated that the strains associated with rhombencephalitis during this study clustered with known strains of L. monocytogenes lineage I from diverse geographical locations and from cattle of the state of Paraná with encephalitic listeriosis. Consequently, these strains should be classified as L. monocytogenes lineage I. These results confirm the active participation of lineage I strains of L. monocytogenes in the etiopathogenesis of the brainstem dysfunctions observed during this study, probably represent the first characterization of small ruminant listeriosis by molecular techniques in Latin America, and suggest that ruminants within the state of Paraná were infected by the strains of the same lineage of L. monocytogenes.

“…Listeria monocytogenes rarely causes disease in horses (Emerson and Jarvis 1968;McCain and Robinson 1976;Clark et al 1978;Welsh 1983;Wallace and Hathcock 1995;Larochelle et al 1999;Wilkins et al 2000). It is described as a cause of abortion, septicaemia in equine neonates, mature horses and ponies and neurological disease in a foal (Emerson and Jarvis 1968;McCain and Robinson 1976;Clark et al 1978;Welsh 1983;Wallace and Hathcock 1995;Larochelle et al 1999;Wilkins et al 2000). Most cases of listeriosis in other species arise from the ingestion of contaminated food and listeriosis is a common disease in ruminants fed on silage, causing encephalitis, abortion and septicaemia (Low and Donachie 1997).…”
