Provedor de dados: 80
Autores: Luvizotto,MCR; Carreira,VS; Ferrari,HF; Ribeiro,D; Vallim,MA; Azevedo,V; Cardoso,TC.
A four-year-old male goat with a history of neurological disorder was euthanized. It presented uncommon nodules in the brain and lungs associated with multiple abscesses, predominantly in the spleen and liver. Histological examination of brain and lung sections revealed yeast forms confirmed to be Cryptococcus gattii after a combination of isolation and polymerase chain reaction (PCR) procedures. Moreover, Corynebacterium pseudotuberculosis infection was diagnosed by PCR of samples from the lung, spleen and liver. The present report highlights the rare concurrent infection of C. gatti and C. pseudotuberculosis in an adult goat from São Paulo state, Brazil, and indicates the necessity of surveillance in the treatment of goats with atypical pulmonary...

Malignant catarrhal fever-like lesions associated with ovine herpesvirus-2 infection in young calves (Bos indicus): a case report
Provedor de dados: 80
Autores: Luvizotto,MCR; Ferrari,HF; Cardoso,TC.
Infection of susceptible ruminants, including domestic cattle (Bos taurus) and American bison (Bison bison), with ovine herpesvirus-2 (OvHV-2) may provoke the fatal vasculitis and lymphoproliferative syndrome, known as malignant catarrhal fever (MCF), reported worldwide. To the best of our knowledge, this is the first report of a clinical case of MCF-like lesions associated with ovine herpesvirus-2 (OvHV-2) infection in young calves (Bos indicus) including central nervous symptoms that occurred in Três Lagoas city, Mato Grosso do Sul state, a border town near São Paulo state, Brazil. The diagnosis was based on typical histological lesions characterized by systemic lymphohistiocytic and fibrinoid vasculitis, confirmed by polymerase chain reaction and...

Pathogenesis of meningoencephalitis in rabbits by bovine herpesvirus type-5 (BHV-5)
Provedor de dados: 59
Autores: Silva,Adriana M. da; Flores,Eduardo F.; Weiblen,Rudi; Canto,Marister C.; Irigoyen,Luiz F.; Roehe,Paulo M.; Sousa,Renato S. de.
This article describes the main aspects of bovine herpesvirus type-5 (BHV-5) neurologic infection and disease in rabbits, a candidate animal model for studying BHV-5 neuropathogenesis. Intranasal inoculation of weanling rabbits with a Brazilian BHV-5 isolate produced neurological disease and death in 78.8% (26/33) of the animals. Neurological signs started as early as 5 days post-inoculation and lasted from 10-12 hours up to several days. Most animals evolved to a moribund state or death within 24 (69.2%) to 48 hours (88.5%). Neurological disease was characterized by excitability or depression, tremors, bruxism, walking or running in circles, backward arching of the head and body, incoordination, backward and sideways falling, paddling, profound depression...

Fungal colonization of the brain: anatomopathological aspects of neurological cryptococcosis
Provedor de dados: 42
Autores: COLOMBO,ANA CAROLINE; RODRIGUES,MARCIO L.
Brain infection by the fungus Cryptococcus neoformans results in an estimated 500,000 human deaths per annum. Colonization of the central nervous system (CNS) by C. neoformans causes different clinical syndromes that involve interaction of a number of fungal components with distinct brain cells. In this manuscript, our literature review confirmed the notion that the Cryptococcus field is expanding rapidly, but also suggested that studies on neuropathogenesis still represent a small fraction of basic research activity in the field. We therefore discussed anatomical and physiological aspects of the brain during infection by C. neoformans, in addition to mechanisms by which brain resident cells interact with the fungus. This review suggests that multiple...

ABSTRACT Meningoencephalitis caused by Bovine herpesvirus 5 (BoHV-5) is an important neurological disease that affects Brazilian cattle herds. The present study investigated the presence of BoHV-5 DNA in cattle diagnosed with meningoencephalitis at Faculdade de Medicina Veterinária e Zootecnia, UNESP - Univ Estadual Paulista from 1980 to 2009. The records obtained from the Large Animal Internal Medicine Service and the Animal Pathology Service were reviewed to identify clinical and epidemiological data from cattle with neurological signs. Excluding rabies cases, we found 115 cases of cattle with neurological signs that had been necropsied. Non-suppurative meningoencephalitis was diagnosed in 28 animals of the 115 initially selected based on...

Bovine herpesvirus 5 (BoHV-5) meningoencephalitis is one of the main causes of mortality by encephalopathy in Brazilian cattle herds. However, the neurological signs observed are common to several encephalopathies and do not contribute decisively to a diagnosis. In order to verify hematological and cerebrospinal fluid (CSF) changes, blood and CSF samples from naturally and experimentally infected bovines were evaluated. In natural cases (n=17), the samples were collected only once, and in experimental cases (n=7), the samples were sequentially obtained throughout disease progression. While routine methods were used to examine the samples, BoHV-5 infection was confirmed by a PCR assay. Blood analyses did not reveal any consistent hematological alterations...

Primary amoebic meningoencephalitis: first reported case from Rohtak, North India
Provedor de dados: 55
Autores: Gupta,Naveen; Bhaskar,Hemlata; Duggal,Shalini; Ghalaut,Pratap S.; Kundra,Shailja; Arora,Des R.
A fatal case of primary amoebic encephalitis (PAM) in a 20 year old boy, a proven case of acute leukemic leukemia (ALL) type L2, in remission is described. No history of swimming could be elicited. The clinical presentation, the isolation of the amoeba from the cerebrospinal fluid (CSF), the poor response to amphotericin B, and the ultimately fatal outcome are all consistent with the diagnosis of PAM. On the basis of its ability to grow at temperature 42ºC and 45ºC, morphology of trophozoite, and the presence of flagellate forms in CSF, the amoeba was identified as Naegleria fowleri. Other drugs used in combination with amphotericin B are tetracycline, rifampicin, and miconazole. A possibility of PAM should always be considered in all cases of acute...

Reactivation of Chagas' disease leading to the diagnosis of acquired immunodeficiency syndrome
Provedor de dados: 55
Autores: Santos,Eder de Oliveira; Canela,João dos Reis; Monção,Henry Carlos Gomes; Roque,Mauro José Guedes.
Reactivation of chronic Chagas' disease is a rare condition and occurs only in immunosuppressed patients. We report a case of a patient with a rapid and fatal reactivation of Chagas' disease, manifested by meningoencephalitis, which lead to a diagnosis of acquired immunodeficiency syndrome (AIDS). We believe there is sufficient evidence to include the reactivation of Chagas' disease among the diagnostic criteria of AIDS in Human Immunodeficiency Virus (HIV) infection.

Meningoencephalitis caused by a zygomycete fungus (Basidiobolus) associated with septic shock in an immunocompetent patient: 1-year follow-up after treatment
Provedor de dados: 56
Autores: Auxiliadora-Martins,M.; Alkmim-Teixeira,G.C.; Machado-Viana,J.; Nicolini,E.A.; Martins-Filho,O.A.; Bellissimo-Rodrigues,F.; Carlotti Jr.,C.G.; Basile-Filho,A.
Zygomycosis is an infection caused by opportunistic fungi of the Zygomycetes class, specifically those from the Mucorales and Entomophthorales orders. It is an uncommon disease, mainly restricted to immunocompromised patients. We report a case of a 73-year-old male patient with a history of fever (39°C) lasting for 1 day, accompanied by shivering, trembling, and intense asthenia. The patient was admitted to the intensive care unit with complex partial seizures, and submitted to orotracheal intubation and mechanical ventilation under sedation with midazolam. The electroencephalogram showed evidence of non-convulsive status epilepticus. There is no fast specific laboratory test that permits confirmation of invasive fungal disease. Unless the physician...

Bovine herpesvirus 5 detection by virus isolation in cell culture and multiplex-PCR in central nervous system from cattle with neurological disease in Brazilian herds
Provedor de dados: 58
Autores: Claus,Marlise Pompeo; Alfieri,Alice Fernandes; Médici,Kerlei Cristina; Lunardi,Michele; Alfieri,Amauri Alcindo.
Bovine herpesvirus 5 (BoHV-5) is an important cause of meningoencephalitis in young and adult cattle. The multiple etiology of neurological disturbances in cattle makes the quick and conclusive diagnosis of BoHV-5 infection important for animal and public health, mainly because of herbivore rabies that is endemic in Brazilian cattle herds. The objective of this retrospective study was to use a multiplex-polymerase chain reaction (multiplex-PCR) for BoHV-5 and BoHV-1 glycoprotein C gene detection from stored central nervous system (CNS) tissue fragments of cattle with neurological clinical signs. Forty-seven frozen CNS samples of young and adult cattle from 31 herds in three Brazilian geographical regions (South, Southeast, and Center-west) were evaluated....

ABSTRACT: A 10-day old foal presented with a history of acute recumbency and generalized weakness, that progressed to seizure episodes and death. Post mortem examination revealed necrotizing and purulent omphalophlebitis and fibrinopurulent meningoencephalomyelitis. Salmonella Typhimurium was isolated from the central nervous system and determined to be the cause of the meningoencephalomyelitis. Due to the lack of evidence of gastrointestinal disease, the umbilical cord was considered the most likely portal of entry of the bacteria. The isolated S. Typhimurium was resistant to ampicillin and cephalotin, and partially resistant to enrofloxacin. These drugs are commonly used in the treatment of salmonellosis. This is the first report of S. Typhimurium...
