“…Gram-negative bacteria, E. coli in particular, are reported to be the most common meningeal pathogens in bovine neonates (Fecteau & George 2004). In sheep and goats, E. coli, Pasteurella, Streptococcus, Staphylococcus pyogenes, and T. (Arcanobacterium) pyogenes have been cultured from meningitis cases (Marchen et al 2005, Lemos & Brum 2007.…”

et al. 2014

In addition to listeriosis which is relatively common in ruminants, there are three other uncommon suppurative intracranial processes (SIP) identifiable in adult ungulates as brain abscess, basilar empyema and suppurative meningitis. The present paper reports the epidemiological, clinical, laboratorial, pathological and microbiological findings of 15 domestic ruminants with SIP. A total of 15 animals were selected (eight sheep, four cattle and three goats); with the definitive diagnoses of basilar empyema (n=3), brain abscess (n=1), listeriosis (n=5) and suppurative meningitis (n=6). Hematology revealed leukocytosis with inversion of the lymphocyte/ neutrophil ratio in 4 cases. In the majority of animals, cerebrospinal fluid (CSF) presented light yellow coloration and cloudy aspect due to neutrophilic pleocytosis (15 -997 leukocytes/µL). Microbiological culture of CSF or central nervous system (CNS) fragments resulted on isolation of Trueperella (Arcanobacterium) pyogenes, Listeria monocytogenes, Escherichia coli and Stenotrophomonas sp. In a goat with thalamic abscess, microbiological assay was not performed, but Gram positive bacilli type bacteria were observed in histology. The diagnosis of these outbreaks was based on the association of epidemiological, clinical, pathological and bacteriological findings; reiterating that the infectious component remains an important cause of CNS disease in domestic ruminants and also shows the need for dissemination of information about the most effective preventive measures for the ranchers. teriológicos; reiterando que o componente infeccioso continua sendo uma causa importante de doença do SNC em ruminantes domésticos e também mostra a necessidade de disseminação da informação sobre as medidas preventivas mais eficazes para os criadores.TERMOS DE INDEXAÇÃO: Abscesso cerebral, animais de produção, empiema basilar, listeriose, meningite supurativa.

“…Although H. somni-related diseases are of economic importance to livestock owners (George 2009), clinical manifestations of disease in cattle is predominant within the USA (Fecteau and George 2004;Woolums et al 2009) and Canada (Van Donkersgoed et al 1990;Gagea et al 2006), with reports of sporadic outbreaks occurring in Europe (Tegtmeier et al 1999;Janosi et al 2009b), Argentina (Descarga et al 2002), Nigeria (Odugbo et al 2009), Japan (Momotani et al 1985;Tanaka et al 2005), and South Africa (Last et al 2001); there is no description of this pathogen affecting cattle in Brazil. Nevertheless, H. somni has also been isolated from healthy goats in Mexico (Perez-Romero et al 2011) and Hungary (Janosi et al 2009a) and has been associated TME in sheep within Europe (Cassidy et al 1997), reproductive disease in sheep from Canada (Lees et al 1990), and in one case of endometritis in a sheep from Brazil (Rizzo et al 2012).…”

Furthermore, H. somni-induced infections are more predominant in young cattle (Harris and Janzen 1989;Van Donkersgoed et al 1990) and in feedlot relative to dairy and pastured animals (Fecteau and George 2004), occurring within the first 2 weeks or months of the feeding period (Woolums et al 2009).…”

The sudden death of three calves, one diarrheic calf, and one aborted fetus from four farms in southern Brazil was investigated. Two Histophilus somni-associated syndromes were identified: systemic histophilosis (n = 4) and abortion (n = 1). The principal pathological findings included vasculitis, meningoencephalitis with thrombosis, necrotizing myocarditis, renal infarctions, hepatic abscesses, and bronchopneumonia. PCR assays were used to amplify specific amplicons of the ovine herpesvirus 2, bovine herpesvirus 1 and -5, Listeria monocytogenes, H. somni, and pestivirus; bovine group A rotavirus (BoRV-A) and bovine coronavirus (BCoV) were investigated in calves with diarrhea. H. somni DNA was amplified in tissues from all calves and the brain of the aborted fetus with pathological alterations consistent with histophilosis. All other PCR assays were negative; BoRV-A and BCoV were not identified. These findings confirm the participation of H. somni in the pathological alterations observed in this study and represent the first description of histophilosis in cattle from Brazil.

RESUMO.-[Doenças infecciosas supurativas do sistema nervoso central de ruminantes domésticos.]Neste trabalho são descritas as doenças neurológicas infecciosas supurativas de ruminantes domésticos na Região Sul do Brasil. Foram avaliados laudos de 3.274 bovinos, 596 ovinos e 391 caprinos, dos quais 219 bovinos, 21 ovinos e sete caprinos foram diagnosticados como doenças inflamatórias no sistema nervoso central. As doenças neurológicas infecciosas supurativas corresponderam a 54 casos (28 bovinos, 19 ovinos e sete caprinos). As enfermidades observadas foram meningoencefalite por Listeria monocytogenes (oito ovinos, cinco caprinos e quatro bovinos), leptomeningite e meningoencefalite supurativa (14 bovinos, dois caprinos e um ovino), abscessos cerebrais (seis bovinos e dois ovinos) e medulares (sete ovinos); e empiema basilar (quatro bovinos e um ovino This study describes suppurative infectious diseases of the central nervous system (CNS) in domestic ruminants of southern Brazil. Reports from 3.274 cattle, 596 sheep and 391 goats were reviewed, of which 219 cattle, 21 sheep and 7 goats were diagnosed with central nervous system inflammatory diseases. Suppurative infectious diseases of the CNS corresponded to 54 cases (28 cattle, 19 sheep and 7 goats). The conditions observed consisted of listerial meningoencephalitis (8 sheep, 5 goats and 4 cattle), suppurative leptomeningitis and meningoencephalitis (14 cattle, 2 goats and 1 sheep), cerebral (6 cattle and 2 sheep), and spinal cord (7 sheep) abscesses, and basilar empyema (4 cattle and 1 sheep). Bacterial culture identified Listeria monocytogenes (9/54 cases), Escherichia coli (7/54 cases), Trueperella pyogenes (6/54 cases) and Proteus mirabilis (1/54 cases). All cases diagnosed as listeriosis through histopathology yielded positive immunostaining on immunohistochemistry, while 12/17 of the cases of suppurative leptomeningitis and meningoencephalitis presented positive immunostaining for Escherichia coli. Meningoencephalitis by L. monocytogenes was the main neurological disease in sheep and goats, followed by spinal cord abscesses in sheep. In cattle, leptomeningitis and suppurative meningoencephalitis was the most frequent neurological disease for the species, and E. coli was the main cause of these lesions. Basilar empyema, mainly diagnosed in cattle, is related to traumatic injuries, mainly in the nasal cavity, and the main etiologic agent was T. pyogenes.
