“…The results could be explained by the used avian species -guineafowl. The investigations of El-Yuguda et al (11,12) with guineafowl vaccinated and infected with IBDV and later, vaccinated with a lentogenic APMV-1 strain La Sota did not perform any attempts for reisolation, but only evaluated the humoral immune response and pathological changes.…”

“…El-Yuguda et al (11,12) conducted trials with guinea fowl and chickens. In two experiments with guinea fowl, they investigated the immune response after vaccination with live infectious bursal disease virus (IBDV) vaccine followed by vaccination with a lentogenic La Sota APMV-1 seven days later.…”

An experiment was conducted to evaluate the effect of a low-pathogenic H6N2 avian influenza A viral strain (LPAIV strain H6N2) on subsequent (after 3 days) vaccination with a lentogenic avian paramyxovirus serotype 1 strain La Sota (APMV-1 strain La Sota) in guinea fowl. The effects were monitored by detection of the presence of viruses in cloacal and oropharyngeal samples, as well as by the presence of humoral immune response. The obtained results were compared to birds with monoinfections. Replication and virus shedding of LPAIV strain H6N2 from the cloaca and the oropharynx were established, while APMV-1 La Sota was reisolated only from the oropharynx. The reisolation of LPAIV strain H6N2 was similar in both monoinfection and co-infection. The dynamics of virus replication of APMV-1 strain La Sota was affected in the beginning of the co-infection, later occurrence of the peak which matched the period of decline of LPAIV strain H6N2 reisolates. The LPAIV strain H6N2 and APMV-1 strain La Sota co-infection did not exert any influence on humoral immune response to both viruses.

“…El-Yuguda et al (2007,2014) (52,53) performed experiments with two bird species (guinea fowl and chickens). In two experimental designs with guinea fowl they investigated the immune response after vaccination with live vaccine of infectious bursal disease virus (IBDV) followed by vaccination with lentogenic La Sota APMV-1 strain 7 days later; while the second design included infection of birds with a pathogenic IBDV strain and vaccination with lentogenic La Sota APMV-1 strain 7 days later.…”

The main features of avian influenza viruses (AIV) and Newcastle disease virus (APMV-1), the possibilities for isolation and identification in laboratory conditions, methods of diagnostics, main hosts, clinical signs and virus shedding are reviewed in chronological order. The other part of the review explains the mechanisms and interactions in cases of co-infection of AIV and APMV-1, either between them or with other pathogens in various indicator systemscell cultures, chick embryos or birds. The emphasis is placed on quantitative data on the virus present mainly in the first ten days following experimental infection of birds, the periods of virus carrier ship and shedding, clinical signs, pathological changes, diagnostic challenges.

“…Other factors to consider include the prevalence of other infectious diseases like IBD capable of immunosuppressing the village chickens. El-Yuguda et al [32] have reported significant depression of primary antibody of chickens to ND vaccine when administered one week after IBD infection or vaccination. It is therefore fundamental to monitor the prevalence of other infectious diseases capable of immunosuppression and to implement specific vaccination programme for their control.…”

A study of response of village chickens to vaccination with ND I 2 vaccine coated on maize grit as vaccine carrier was carried out in some selected LGAs of Gombe State, using haemagglutination inhibition (HI) test. Vaccination efficacy of maize grit coated with Newcastles Disease I 2 vaccine has been compared between adult and young, village chickens. The study showed that 94.3% of the vaccinated village chickens (adults and chicks) seroconverted with protective levels of antibodies against ND virus. Those vaccinated with the maize grit coated vaccine exhibited antibody titres of between 1:16 to 1:8192 with GMT values of 109 to 245. There was a significant difference (P<0.05) in the response of the vaccinated adult village chickens as compared to the younger birds (chicks). It is concluded from the study that maize grit is a very suitable vaccine carrier for the delivery of ND I 2 vaccine to village chickens.
