A cross-sectional study was conducted to estimate the seroprevalence of Newcastle disease (ND) in backyard chickens at Gazipur district of Bangladesh. Individual serum sample was collected from clinically healthy and non-immunized backyard chickens in four randomly selected upazilla (Sreepur, Kapasia, Kaliakor and Gazipur sadar) under Gazipur district. A total of two hundred samples (50 from each upazila) were collected from October 2009 to February 2010. Haemagglutination Inhibition (HI) test was used to determine titer of antibodies against Newcastle disease virus. The mean log2 HI titer to NDV in blood sera of the study population were found 5.54, 6.25, 4.38, 5.32 and seroprevalence were 42.53%, 45.99%, 31.91%, and37.82% in Sreepur, Kapasia, Kaliakor and Gazipur sadar upazilas respectively. The overall antibody titer and seroprevalence of Newcastle disease virus was recorded 5.37 and 39.56% respectively. Further detailed study focusing on Newcastle Disease (ND) virus strain identification and improved management packages to reduce the prevalence of Newcastle Disease (ND) are recommended.International Journal of Natural Sciences (2013), 3(1-4) 22-25

Background and Aim: The chicken gut harbors microflora which impacts the health, production performance and immune response against pathogens. Assam local chickens reared under natural conditions are known to possess high immunocompetence which may be attributable to its gut microbiota make-up. This study aimed to investigate the individual effect of two strains of Lactobacillus reuteri PIA16 isolated separately from cecum and jejunum of Assam indigenous chicken on the immunity of broiler chickens against Newcastle disease virus (NDV) when fed singly and in combination with a prebiotic. Materials and Methods: A total of 240 birds (48 per group) were vaccinated with Lasota strain of NDV on the 5th and 21st day of age. Blood samples were collected before and after immunization against ND for the detection of humoral antibody response by hemagglutination inhibition test. The cell-mediated immune (CMI) response was estimated through response to phytohemagglutinin-P (PHA-P) and expressed as web index. Results: A significant influence on the immune response to NDV was observed in all the L. reuteri PIA16 as well as mannan oligosaccharide (MOS) supplemented groups revealing higher antibody titer than the control counterpart. The CMI response revealed a better cutaneous basophilic hypersensitivity response to PHA-P in the treated groups than the control. Conclusion: Enhancement in immunity was perceived in the broilers fed with L. reuteri PIA16 and in combination with MOS due to the stimulation of the host's humoral and CMI response by the probiotics and prebiotics used.

Aim: This study aimed to assess the level of awareness of rural poultry farmers on vaccination and to detect Newcastle disease virus (NDV) antibody in local birds (LB) and eggs in Kwara State, Nigeria. Materials and Methods: Data on farmers' attitude, knowledge, practices, and experiences on ND mortality were obtained through an interview using a structured cross-sectional checklist. NDV antibodies were detected in sera and egg yolks of local chickens (LC) and guinea fowls (GF) using hemagglutination inhibition test. Results: A total of 83 interviewees, 287 sera and 121 egg yolk extracts, were examined. The study revealed that 98.8% (82/83) of the interviewee had never vaccinated their flock before. 90% of the interviewee had reported high mortality in birds within 1-6 months old, while the major clinical signs were cold (40.4%) and torticollis (30.8%). Evidences of LB exposure to wild-type NDV were confirmed by the detection of NDV antibodies in 20.8% and 0% of LC and GF, respectively. The mortality differences experienced in <1 and 1-6 months old LB could be explained by the presence of maternally-derived NDV antibody (49.6%) in egg yolk. Conclusion: The study showed that LB suffers from NDV as a result of LB keepers' ignorance and neglect by the government. This has limited local investment and subsequent contribution to gross domestic product. This study suggests that the key factors to the prevention of ND remain awareness creation about poultry vaccination, production of affordable vaccines, and availability/accessibility to veterinarian (or trained personnel).

In Rwanda, the most prevalent livestock farming activity carried out to improve livelihoods in rural areas is poultry farming. The most common bird species raised for egg and meat production is indigenous chicken (IC). Despite its economic significance, the improvement programs in Rwanda have given IC little attention. There is, therefore, little documentation on their production and disease resistance performance. This study aimed at evaluating the growth performance and immunologic response of IC against Newcastle disease vaccine in four gene pools in Rwanda. One hundred eighty-nine (189) IC from four gene pools were kept on-station using a completely randomized design. Thereafter, the IC were vaccinated with a live commercial Newcastle disease virus. Data on body weight were collected weekly for 20 weeks whereas serum samples were collected after 35 days. Antibody responses were determined using indirect ELISA. Analysis of variance was performed using the SAS Generalised Linear Model procedure. Growth patterns were modelled using the logistic function. Results revealed a highly significant difference (P<0.001) for growth performance and antibody response to Newcastle disease vaccine among the four gene pools. Gene pool A was the heaviest (1.6 kg) in the period of 20 weeks and gene pool C expressed the highest immune response (8,161antibody titres) for Newcastle disease vaccine (P<0.001). The results indicated that the selection of gene pool A in breeding could yield IC with good growth performance trait whilst gene pool C could be selected for its higher immunity against Newcastle disease virus.

A cross-sectional study was conducted in five provinces and 11 districts of Zambia to determine the seroprevalence of Newcastle disease in Zambian backyard chicken flocks. Of the chickens sampled, 73.9% tested positive for avian paramyxovirus type 1 antibodies by means of an enzyme-linked immunosorbent assay. Seroprevalence varied amongst the five provinces sampled, ranging from 82.6% in the Eastern Province to 48.3% in Luapula Province. Seroprevalence also varied amongst the 11 districts sampled, ranging from 91.3% in Monze district of Southern Province to 22.8% in Mufulira district of the Copperbelt province. Overall, the seroprevalence of Newcastle disease in Zambian backyard chicken flocks has increased since the previous study conducted in 1994.
