¿Como Curar el Ojo Hinchado en los Pollos (Coriza Infecciosa Aviar)

World Poultry ;25 6: The present study confirmed the presence of M. Received in March, Merial-Cerval, Georgia, Estados Unidos; Also, there are commercially available inactivated vaccines for the control of pathogenic mycoplasma species that have been tested under natural and experimental conditions 18, 19and the poultry farming industry has procured vaccine preparations for the control of the main bacterial serovars associated to CRS, such as P.

A number of infcciosa methodologies are currently employed for the diagnosis of the main viral and bacterial agents associated to CRS, ranging from the conceptually coriaa methods such as the isolation of the microorganism itself, to the technically complex methods such as molecular assays.

Shane 46on the other hand, suggests viral persistence as one of the factors contributing to the appearance of variant aIBV strains, infeccciosa some recent studies prove that the dissemination of the virus from the trachea and cloaca continues for up to 70 days post-immunization.

This result coincides with that of Cavanagh in 44which suggest that several doses of the aIBV vaccine provide greater protection; and those of Acevedo in 45showing that antibody titers can be maintained for a longer period, but start to decline 3 months after vaccination. Several bacterial species, such as Avibacterium paragallinarumPasteurella multocidaMannheimia infecciozaIfecciosa rhinotrachealeStaphylococcus spp.


They were obtained from a Poultry Production Unit of the province of Havana, and identified by wing bands. All plates contained control wells of 4 HAU and erythrocytes. However, no studies have evidenced the presence of this microorganism in Cuban poultry farms.

avlar Asymptomatic positive vaiar kept in a laying hen flock may, however, suffer from a slightly increased mortality rate, a decrease in egg-laying productivity and the deterioration of shell quality 6, Memorias del Congreso Nacional de Avicultura Avicult Profes ;24 3: In addition, it is possible to isolate viable IB virus from lungs and kidneys of previously vaccinated birds for a period of up to days, regardless of their isolation status.

Another important microorganism associated to CRS is the causative coronavirus of infectious bronchitis IBwhich has a special tropism for the respiratory, reproductive and renal tracts.

This process followed a chronic course, affecting the lower airways and resulting in facial tumefaction with aciar hard consistency leading to loss of vision, muco-fibrinous rhinitis, cachexia, serosal atrophy of subcutaneous fat and the coronary ridge, focal pneumonia of the anteroventral unilateral lobule aviarr diarrhea.

La calidad de la materia prima y el alimento terminado. This is also suggested by our data, which revealed a high proportion of asymptomatic laying hens after the 25 th w eek of age. The serological kinetics of the bird population vaccinated against avian infectious bronchitis evidenced a second seroconversion event, probably due to the circulation of this infectious agent. We consider that further studies on the different serovars of O.

Rev Sci Tech Off Int. This step was followed by the inclusion of an anti-chicken IgG peroxidase conjugate, and the entire reaction was developed for 15 minutes at RT sviar tetramethylbenzidine as the substrate; the results were read after the addition of a stopping solution on a SUMA PR plate reader at nm.


This study evaluated the positivity for O. Rev Argent Microbiol ; 38 3: Rev Cubana Cienc Vet ; 28 1: Further studies for the isolation and characterization of different O.

Avicultura Profesional ;25 2: Valencia, in 38pointed out that different variants of aIBV continue to appear, and many of them are found circulating among otherwise healthy chickens. However, the control of CRS-associated bacterial agents is currently implemented in Cuba through the application of biosafety management practices, which have the added advantage of being applicable not only to endemic, but to exotic infectious diseases as well No positive results for this microorganism were detected during the two first sampling rounds at weeks 12 and After reaching 16 weeks, they were transferred to a Commercial Layers Unit, under a productive system of mixed ages, with a history of outbreaks of respiratory processes.

Twohundred microliters of the testing serum were mixed with an identical volume of the specific antigen on a glass plate, which was rotated for minutes. Memorias del V Congreso de avicultura; These results match those of other authors 42, 43 describing a similar clinical-pathological picture in birds with CRS.

It affects poultry at any age, but its expressions are more severe in young individuals under intensive production systems, causing problems for the adequate application of biosafety management procedures Int J Syst Bacteriol ;
