1. Severe Outbreak of Avian Encephalomyelitis in Laying Hens in Northeastern Brazil
ABSTRACT This paper describes the epidemiological, clinical and pathological aspects of an avian encephalomyelitis (AE) outbreak in commercial laying hens in Northeastern Brazil. The disease affected 23,409 layers (from day one until 100 weeks) leading to mortality of 16.5% (5,049/30,600) of the flock. Twenty laying hens were clinically examined, and blood s

2. NEW OCCURANCE OF AVIAN ENCEPHALOMYELITIS IN BROILER - IS THIS AN EMERGING DISEASE?
ABSTRACTAvian encephalomyelitis is caused by an Hepatovirus and primarily affects chickens. Chickens of all ages are susceptible to the virus, but the nervous symptoms are manifested only in young chicks, between one to five weeks of age. During the last thirty years, avian encephalomyelitis appeared to be well controlled by breeder vaccination. However, the

3. Feeding different levels of vitamin E and selenium has no effect on serum immunoglobulin Y (IgY) production by layers vaccinated against Escherichia coli and avian encephalomyelitis virus / Alimentação com diferentes níveis de vitamina E e selênio não influencia a produção de imunoglobulina Y (IgY) no soro de poedeiras leves vacinadas contra Escherichia coli e encefalomielite aviária
Os efeitos da suplementação de vitamina E e Selênio (Se) na imunidade de galinhas vacinadas contra uma mistura de 6 sorotipos patogênicos de Escherichia coli (EC) e o vírus da encefalomielite aviária (VEA) foram estudados. A produção de anticorpos foi avaliada em galinhas H&N Nick Chick durante a 49a e 57a semanas de vida. As aves foram alimentadas c

4. Detecção do vírus da anemia infecciosa das galinhas em Minas Gerais
A wide range study was conducted on chicken anemia virus (CAV) in order to investigate the occurrence of CAV in different chicken populations and potential sources of infection. Tissue and biological samples were studied by nested PCR and sequencing, including thirty-two industrial chickens, twenty subsistence chickens, twenty-eight commercial poultry live a

6. Serotyping of Chlamydia: isolates of bovine origin.
Chlamydial isolates of bovine origin were serotyped by a plaque reduction method. Of the two major serotypes observed, type 1 included isolates from bovine abortion and enteric infections, whereas type 2 isolates were associated with polyarthritis or encephalomyelitis. These two serotypes were identical to those with a similar disease distribution previously

7. Comparison of Chlamydia psittaci isolates by restriction endonuclease and DNA probe analyses.
DNAs from eight Chlamydia psittaci isolates (koala conjunctivitis, avian psittacosis, avian ornithosis, ovine abortion, ovine polyarthritis, sporadic bovine encephalomyelitis, and feline conjunctivitis) and one Chlamydia trachomatis isolate (lymphogranuloma venereum) were compared by restriction endonuclease and DNA probe analyses. Digestion with HindIII yie

8. Characterization of a Coronavirus Isolated from a Diarrheic Foal
A coronavirus was isolated from feces of a diarrheic foal and serially propagated in human rectal adenocarcinoma (HRT-18) cells. Antigenic and genomic characterizations of the virus (isolate NC99) were based on serological comparison with other avian and mammalian coronaviruses and sequence analysis of the nucleocapsid (N) protein gene. Indirect fluorescent-

9. Molecular Analysis of Three Ljungan Virus Isolates Reveals a New, Close-to-Root Lineage of the Picornaviridae with a Cluster of Two Unrelated 2A Proteins†
Ljungan virus (LV) is a suspected human pathogen recently isolated from bank voles (Clethrionomys glareolus). In the present study, it is revealed through comparative sequence analysis that three newly determined Swedish LV genomes are closely related and possess a deviant picornavirus-like organization: 5′ untranslated region-VP0-VP3-VP1-2A1-2A2-2B-2C-3A-
