For the preparation of an effective fowl pox vaccine, comparative studies of a number of fowl and pigeon pox virus strains were accomplished, and the following conclusions were made. 1. Anyang-Nakano strain which was nation widely used as a seed virus of fowl pox vaccine was proven its inadequacy. 2. A liquid vaccine prepared with Minnesota strain of pigeon pox virus showed its stability for 6 months and on side reaction.

The humoral immune response of chicken vaccinated with fowl and pigeon pox virus vaccines was determined with the protective potentiality of the two vaccines in field condition of Bangladesh. Different aged Fayoumi chicks were subjected for the study. To assess the relationship with better immune response among experimental groups, the average percentage of 'take reaction' was examined and recorded to 97.77% in group A, 93.33% in group B and 100.0% in group C. The level of immune status induced by different vaccinated group was measured by passive hemagglutination (PHA) microplate test method. The mean PHA titer levels after primary vaccination were $33.06{\pm}14.13$ in group A, $32.0{\pm}14.81$ in group B, and $33.0{\pm}13.66$ in group C. Following booster vaccination, the mean PHA titer levels in prior of challenge were increased to $55.46{\pm}14.64$ in groups A and C, and $46.93{\pm}16.52$ in group B. The recorded PHA titer levels of each group at two weeks after challenge were significantly increased to $106.66{\pm}31.22$, $93.86{\pm}33.04$ and $110.93{\pm}29.29$, respectively. The PHA titer levels after vaccination and challenge were significantly increased compared to pre-vaccination titer levels (P<0.01). Although the PHA titer levels among three groups administrated different vaccine combinations in prior of challenge were significantly varied (P<0.01), it was observed that all of the vaccinated chicks were highly protected against challenge infection.

Bird species, particularly poultry and other bird types, including domestic pigeons, are susceptible to fowl pox, a contagious viral disease. The main goal of this study was to validate clinical avipoxvirus diagnoses using molecular analytical methods. The essential components of the investigation were the clinical signs, visible abnormalities, histological changes, and polymerase chain reaction analysis. Twenty out of 120 pigeons had clinical symptoms, which included yellowish crust or nodules near the feet, eyes, and beak. An erosive epidermal lesion and an epidermal acanthotic papular lesion with basal vacuolation were maculopapular evidence associated with significant epidermal hyperkeratosis, as confirmed by histological analysis. In addition, the results showed keratinocyte necrosis beneath the hyperkeratotic epidermal layer, together with superficial and deep dermal perivascular lymphocytic infiltration. In addition, the P4b core protein gene underwent phylogenetic analysis. The sequence analysis results indicated a high degree of similarity across the local strains, with just minor variations observed. Five sample sequences were selected and submitted to the NCBI database. These sequences were identified as OR187728, OR187729, OR187730, OR187731, and OR187732. All the various strains in this research may be classified under clade A of the chicken pox virus phylogenetic classification. This study presents the first description and characterization of pox virus infections in domestic pigeons inside the Basrah governorate.

파유미 종 닭에 계두 및 구두 백신을 접종하고 2종의 백신에 대한 방어 능력을 방글라대쉬의 야외의 닭 사육 조건에서 비교하였다. 'Take reaction'의 수율을 평가하여 이것을 더 나은 면역 반응과 관련지어 해석하였으며, 그룹 B와 그룹 C의 닭은 각각 93.33%와 100%의 면역 반응을 보여주었다. 1차 예방접종에 따른 평균 PHA 항체가는 B와 C 그룹에서 각각 $32{\pm}14.81$과 $33{\pm}13.66$으로 나타났다. 보강 접종 후 평균 PHA 항체가는 B 및 C 그룹의 전 처리군에서는 $46.93{\pm}16.52$와 $55.46{\pm}14.64$이었으며, 공격접종 2주 후 시점에서 향체가는 각각 $93.86{\pm}33.04$와 $110.93{\pm}29.29$로 나타났다. PHA 항체가는 백신 접종 후와 접종 후 처치군들에서 백신접종 전 항체가에 비해 현저하게 증가함을 보여주었다. 이렇게 현저한 PHA 항체가의 차이는 사용한 백신의 종류가 다양함으로 인해 발생되는 것이기도 하였으나, 백신 접종을 받은 모든 닭들은 감염에 대한 저항력을 보여주었다.
