No serological responses against Newcastle Disease Virus were detected. Memorias del V Congreso de avicultura; Sampling Blood samples were taken monthly from week 12 and up to week 50, by puncturing the marginal vein of the wing.

The results were interpreted as aivar by the manufacturer, considering a sample as positive for antibodies against aIBV if the serum titer was higher thanand positive to O. This process followed a chronic course, affecting the lower airways and resulting in facial tumefaction with a 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 and diarrhea.

Another important microorganism associated to CRS is the inrecciosa coronavirus of infectious bronchitis IBwhich has a special tropism for the respiratory, reproductive and renal tracts. Epiz ; 15 4: When studying the proportion of birds reactive to M.

Rev Cubana Cienc Vet ; 28 1: Rev Argent Microbiol ; 38 3: Avicult Profes ;26 5: However, another significant increase in Ab titers against aIBV is detected at week 33 among otherwise asymptomatic individuals.

Avicultura Profesional ;25 2: Centro Nacional de Sanidad Agropecuaria; 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. Merial-Cerval, Georgia, Estados Unidos; The present study has detected birds reactive to M. 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.

J Vet Anim Sci ; Rev Sci Tech Off Int. However, for an infection with M.

The incidence of pneumotropic viruses is often controlled through the implementation of biosafety management practices and the application of live or inactivated vaccines that elicit a specific immune response corlza These outbreaks not only affect their genetic, productive and breeding potential, but result in significant economic losses due to decreases in egg and meat production and increases in medication expenses.

The control of BI in Cuban flocks in intensive production systems is implemented through the immunization of replacement layer pullets and the evaluation of the serological response of layers, which enables the inecciosa of the level of protection or the detection of viral infections if antibody levels are monitored at different time points after vaccination 33, The results corroborated the presence of M.

An analysis of variance Anova was performed for the geometric means of the aciar of anti-aIBV antibodies, using the statistical software packages Comprop-1 and Statgraphics Plus 5. Received in March, A number of diverse methodologies are currently employed for the diagnosis of the main viral and bacterial agents associated to CRS, ranging from the conceptually simple methods such as the isolation of the microorganism itself, to the technically complex methods such as molecular assays.

Its isolation and identification as a pathogenic agent in commercial poultry farming occurred infeciosa the beginning of the nineteen nineties by Vandamme et al. Several bacterial species, such as Avibacterium paragallinarumPasteurella multocidaMannheimia haemolyticaOrnithobacterium rhinotrachealeStaphylococcus spp.

The HIA titers measured when evaluating the birds for NDV do not suggest an ongoing infection, but rather demonstrate the efficacy of the vaccine. infeccioza

Historia y algunos nuevos conceptos sobre coriza infecciosa [1970]

In the light of this result, we concluded that no association of NDV with CRS could be detected in the population analyzed. However, no studies have evidenced the presence of this microorganism in Cuban poultry farms.

Evaluation of three different vaccination regimes against Newcastle disease in central Anatolia Turk. Avicult Profes ;24 1: Memorias del Congreso Nacional de Avicultura This confirms the efficacy of the vaccine, as underscored by Viamontes et al.

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. Atenas, Estados Unidos; Avicult Profes ;24 3: Cuba, where the poultry stock undergo extensive immunization following the established mass-scale vaccination programs and where biosafety procedures and practices are enforced, still experiences outbreaks of respiratory disease with high morbidity and low mortality in laying hens.

However, the control of CRS-associated bacterial agents is currently implemented in Cuba through the application afiar biosafety management practices, which have the added advantage of being applicable not only to endemic, but to exotic infectious diseases as well Serology The serological study for the indirect demonstration of the presence of birds infecfiosa to M.

They were obtained from a Poultry Production Unit of the province of Havana, and identified by wing bands. Severe acute respiratory syndrome vaccine development: Alzamora L, Andina I.

Desde las 12 hasta las 50 semanas de edad, mensualmente se muestrearon estas aves. As a whole, these results help to infeccioosa characterize the Cuban epidemiological situation and can be used to defi ijfecciosa the sanitary procedures required for the control of these diseases.

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 analysis of the geometric means of the titers of antibodies against aIBV Figure 3 revealed an increase in this parameter starting at week 16 and peaking at week Twohundred microliters of the testing serum were mixed with an identical volume of the specific antigen infecciowa a glass plate, which was rotated for minutes.

Several authors have reported that the association of M.
