O presente estudo relata a ocorrência de co-infecção entre o vírus da cinomose canina (CDV) e Toxoplama gondii em cães com sinais neurológicos. Amostras de soro e tecido nervoso (pos-mortem) de 21 cães, suspeitos de cinomose canina foram analisadas pela Reação de Imunofluorecência indireta (RIFI) para pesquisa de anticorpos contra T. gondii e N. caninum e por RT-PCR para CDV. Dezessete (80,9%) cães foram positivos para o CDV pela RT-PCR e 8 (38,1%) foram positivos para anticorpos contra T. gondii. Sete cães (41,1%) apresentaram-se positivos para ambos agentes, caracterizando processo de co-infecção. Somente 1 (4,7%) cão foi soropositivo para N. caninum (RIFI=100), entretanto este mesmo animal foi positivo para T. gondii (RIFI=4096) e para CDV (RT-PCR).

During a series of experiments attempting to reproduce clinically apparent bovine herpesvirus type 5 (BoHV-5) infections, a group of calves was inadvertently infected with bovine viral diarrhoea virus (BVDV). Another group of calves was infected with BoHV-5 only. This paper reports the outcome of such infections. Two out of six calves solely infected with BoHV-5 displayed moderate to severe clinical signs. Three out of four calves of the group co-infected with BoHV-5 and BVDV developed severe clinical signs, two of them died. BoHV-5 virus was isolated to higher titres and for a longer period from the group of calves infected with both viruses. These results suggest that BVDV may enhance clinical signs induced by BoHV-5 and may also play a role in extending...

ABSTRACT Bovine alphaherpesviruses 1 and 5 (BoHV-1/5) are main pathogens of respiratory, reproductive and neurological diseases in cattle. The aim of this study was to investigate the frequency of neutralizing antibodies against BoHV-1/5 in serum samples and to detect viral DNA in semen of bulls from beef cattle farms located in RS. A total of 372 serum and semen sample from bulls were collected in eighteen farms. Serum samples were submitted to virus neutralization (VN) assay, while semen samples were used to detect BoHV-1 and BoHV-5 DNA by PCR. VN results showed that BoHV-1/5 antibodies were detected in bulls of 66.7% (12/18) of the farms, 295 (79.5%) BoHV positive bulls, 287 for BoHV-1 and 234 for BoHV-; at 43 vaccinated bulls 72.1% (31/43) showing...

The common occurrence of multiple papillomavirus infections has been shown in several studies involving the human host. However, investigations with the aim of identifying mixed papillomavirus infections in cattle have been conducted only recently. In the current work we describe a co-infection with two different bovine papillomavirus (BPV) types that was identified in a bovine teat papilloma. The skin wart was obtained from a cow belonging to a Brazilian beef herd. A PCR assay was carried out with the FAP primer pair, which amplifies a partial segment of the L1 gene (approximately 478 bp), and the amplicon was submitted to direct sequencing. Because nucleotide sequences with satisfactory quality scores were not obtained, the amplicon was cloned and...

Provedor de dados: 52
Autores: Barry,Aline Fernandes; Alfieri,Alice Fernandes; Stipp,Danilo Tancler; Alfieri,Amauri Alcindo.
Neonatal diarrhea is an important cause of economic losses for cattle farmers. The main viral etiologies of enteric diseases are group A rotaviruses (GARV) and the bovine coronavirus (BCoV). Although both viruses infect calves of the same age, the occurrence of mixed infections is still under studied. The present study describes the co-infection of BCoV and GARV in stool samples. Forty-four diarrheic fecal samples from calves up to 60 days old that had previously tested positive for GARV by SS-PAGE were analyzed using semi-nested PCR for BCoV. A product with 251 bp of the BCoV nucleoprotein gene was amplified in 15.9% (7/44) of the samples, demonstrating that co-infection is not an unusual event. These results reinforce the need for testing for both GARV...

Co-infection with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) is increasingly common and affects the clinical course of chronic hepatitis C. Highly active antiretroviral therapy has improved the life expectancy of HIV infected patients, but, by extending survival, it permits the development of HCV cirrhosis. This study tried to evaluate clinical and epidemiological features of patients with chronic hepatitis C co-infected with HIV. We evaluated 134 HCV-infected patients: i) group A - 65 co-infected HCV/HIV patients, ii) group B - 69 mono-infected HCV patients. The impact of HIV infection on HCV liver disease was analyzed using Child's score, ultrasound findings and liver histology. Patients were subjected to HCV genotyping and anti-HBs...

Abstract JC virus (JCV) is a member of the Polyomaviridae family and is associated to a severe disease known as progressive multifocal leukoencephalopathy, PML, which is gradually increasing in incidence as an opportunistic infection among AIDS patients. The present study aimed to investigate the occurrence of JCV among HIV-1 carriers including their types and molecular subtypes and the possible association with disease. Urine samples from 66 HIV-1 infected subjects were investigated for the presence of the virus by amplifying VP1 (215 bp) and IG (610 bp) regions using the polymerase chain reaction. JCV was detected in 32% of the samples. The results confirmed the occurrence of type B (subtype Af2); in addition, another polyomavirus, BKV, was also detected...

Autores: Hirschheimer,Mário; Silva,Paulo S. L.; Giudici,Roseli; Carrilho,Milene; Mauad,Thais; Ishida,Maria.
Lower respiratory tract infections by respiratory syncytial virus (RSV) are frequent in childhood. Association of RSV with bronchiolitis obliterans has rarely been established. We report a 13-month-old child with bronchiolitis obliterans following co-infection by RSV and adenovirus, and suggest that complicated evolution of an acute bronchiolitis case can indicate an association of pathogens.

Provedor de dados: 55
Autores: Kuehlkamp,Valdete Meurer; Schuelter-Trevisol,Fabiana.
The hepatitis C virus and human immunodeficiency virus share the same transmission routes, which makes co-infection an unfavorable condition for the natural history of both viral diseases. In this context, it should be highlighted that the knowledge of the extent of co-infection and associated risk factors is a vital tool for prevention and control over infectious diseases. The aim of this study was to review the literature, seeking to examine the prevalence of human immunodeficiency virus/hepatitis C virus co-infection reported in studies conducted in Brazil, and identify the main risk factors associated with co-infection. The electronic search was conducted in the Medline, Lilacs and SciELO databases. The following keywords were used: human...

Autores: Ferreira,Carla Elizabeth de Oliveira; Raboni,Sonia Mara; Pereira,Luciane Aparecida; Nogueira,Meri Bordignon; Vidal,Luine Rosele Renaud; Almeida,Sérgio Monteiro.
BACKGROUND: Acute gastroenteritis (AGE) is a common disorder that affects children worldwide. It is usually caused by viral agents, including rotavirus, enteric adenovirus, norovirus, and astrovirus groups. Currently, there are few reports about co-infection among these viruses, mainly in Brazil. METHODS: This is a retrospective study in which 84 rotavirus-positive samples from hospitalized patients at a teaching hospital in Southern Brazil, collected in the 2001-2010 period, were analyzed by polymerase chain reaction (PCR) and reverse transcription - polymerase chain reaction (RT-PCR), for the investigation of enteric adenovirus, astrovirus, and norovirus. RESULTS: In total, 12 of the 84 (14%) samples were positive to enteric adenovirus or norovirus....

ABSTRACT Although the use of vaccines has controlled enteric diseases in dogs in many developed countries, vaccine coverage is still under optimal situation in Brazil. There is a large population of nonimmunized dogs and few studies about the identification of the viruses associated with diarrhea. To address this situation, stool samples from 325 dogs were analyzed by polymerase chain reaction for the detection of common enteric viruses such as Canine adenovirus (CAdV), Canine coronavirus (CCoV), Canine distemper virus (CDV), Canine rotavirus (CRV) and Carnivorous protoparvovirus 1 (canine parvovirus 2; CPV-2). At least one of these species was detected in 56.6% (184/325) of the samples. The viruses detected most frequently in either diarrheic or...
