1. Epidemiology of Avian Infectious Laryngotracheitis with Special Focus to South America: an update
ABSTRACT Avian Infectious laryngotracheitis (AILT) is a respiratory tract disease of great importance because it causes significant economic losses in the poultry industry around the world. It is caused by a Gallid herpesvirus type 1, a member of the genus Iltovirus. The target system for Avian Infectious Laryngotracheitis virus (AILTV) infections is the res

2. Occurrence of infectious Laryngotracheitis Virus (ILTV) in 2009-2013 in the State of São Paulo - Brazil
Infectious laryngotracheitis is a very important respiratory disease because it causes significant economic losses in the poultry industry. The target of ILTV infections is the respiratory system, and the main organ in which the virus remains latent is the trigeminal ganglia. However, the virus has demonstrated tropism for other organs as well. The present s

3. Pathological, immunohistochemical, and molecular findings in commercial laying hens and in backyard chickens naturally infected with the infectious laryngotracheitis virus
Seventy-eight chickens from a very high poultry density (approximately eight million) region and twelve backyard chickens from neighboring areas were analyzed by histopathology and additional techniques for the presence of the infectious laryngotracheitis virus. The virus distribution was determined in different tissues using immunohistochemistry (IHC) and p

4. Comparision of different cell cultures for replication of infectious laryngotracheitis virus from chickens / Comparação de diferentes cultivos celulares para a replicação do vírus da laringotraqueíte infecciosa das galinhas
A propagação do vírus da laringotraqueíte infecciosa tem sido descrita usando culturas de células primárias derivadas de fígado e rim de embrião de galinha ou ovos embrionados, entretanto, essas culturas necessitam de ovos livres de patógenos específicos (SPF) que tomam tempo e custam caro. Desta maneira, culturas de células de linhagem são mais

5. Laryngotracheitis : reproducibility of the disease and comparison of diagnostic methods / Laringotraqueíte: reprodutibilidade da doença e comparação de métodos de diagnóstico
O vírus da laringotraqueíte (VLT) causa de leve a severa doença respiratório em galinhas, o propósito do nosso estudo foi usar um isolado brasileiro de VLT para reproduzir a doença em frangos através da infecção experimental e comparar três métodos de diagnóstico (nested PCR, isolamento viral e histopatologia) para detectar o VLT. Quarenta e oito

6. Diverse uses of feathers with emphasis on diagnosis of avian viral infections and vaccine virus monitoring
The large amounts of feathers produced by the poultry industry, that is considered as a waste was explored for possible uses in various industries, such as meals for animals, biofuels, biodegradable plastic materials, combating water pollution and more. That review mentions these uses, but concentrate on the utilization of feathers for the diagnosis of viral

7. Epidemiologia molecular do vírus da laringotraqueíte infecciosa isolados de surtos em poedeiras comerciais no Estado de São Paulo / Molecular epidemiology of Infectious laryngotracheitis vírus isolated from an outbreak in commercial layer flocks in São Paulo State
The objective of this study was the molecular detection and characterization of field isolates of infectious laryngotracheitis virus (ILTV) detected from commercial chickens with and without clinical signs of the disease from regions of the São Paulo state. The study included samples collected during and after of the first epidemic infectious laryngotrachei

8. Caracterização biológica e molecular de amostras brasileiras do vírus da laringotraqueíte infecciosa.
Atualmente, o Brasil é o segundo maior produtor e exportador mundial de frango. Doenças respiratórias compreendem o principal problema sanitário e levam à condenação de um grande número de carcaças, além de perdas na produtividade. Dentre estes problemas, o vírus da laringotraqueíte infecciosa (VLTI) tem adquirido grande importância nos últimos

9. Survey of infectious laryngotracheitis outbreak in layer hens and differential diagnosis with other respiratory pathogens
Trachea, lung, and conjunctive samples from 51 commercial layer farms from Bastos region, São Paulo, Brazil, were submitted to nested-PCR and virus isolation in SPF chicken embryos for ILT diagnosis. This region experienced an outbreak characterized by respiratory signs, decrease in egg production and increased mortality. Out of the 51 tested field samples,

10. Infectious laryngotracheitis virus: detection and molecular characterization, isolation, differential diagnosis and epidemiology of an outbreak in commercial layer flocks in Bastos region, São Paulo State / Vírus da laringotraqueíte infecciosa: detecção e caracterização molecular, isolamento, diagnóstico diferencial e epidemiologia de um surto em granjas de poedeiras comerciais na região de Bastos, Estado de São Paulo
O presente trabalho descreve o desenvolvimento de uma técnica de nested-PCR para a detecção de ADN do vírus da laringotraqueíte infecciosa (VLTI) utilizando primers que amplificam uma região do gene que codifica a glicoproteína E viral. A técnica padronizada amplificou amostras isoladas e de campo, mostrando alta sensibilidade e especificidade tomand

11. Detection and molecular characterization of infectious laryngotracheitis virus in laying hens in Brazil
Avian Infectious Laryngotracheitis, caused by Infectious Laryngotracheitis Virus (ILTV), has been reported for decades in Brazilian laying and broiler flocks. More recently, outbreaks have occurred in São Paulo State. This study reports the application of PCR and DNA sequencing targeted to the p32 gene of ILTV using laying chicken samples from Bastos, São

12. Infectious laryngotracheitis: a review
Infectious laryngotracheitis (ILT) herpesvirus continues to cause outbreaks of respiratory disease in chickens world-wide. Sporadic cases of ILT occur in all classes of birds, including hobby/show/game chickens, broilers, heavy breeders, and commercial laying hens. These epornitics of ILT tend to occur where there are large populations of naïve, unvaccinate
