“…The diseases prevalent in the Dormaa District do not deviate from the common diseases found within the poultry industry in other parts of the world (McPherson, 1956;Adene, 1990;Wilson, 2007;and Orsi et al, 2010).…”

The poultry industry is perceived to be a major contributor to Ghana's development through employment creation and the enhancement of nutrition and food security. In spite of these contributions, the poultry industry is entangled with a number of problems that necessitate redress. The purpose of the study was to determine how activities within the poultry industry are operationalised, examine the prospects and challenges that confront the industry and make recommendations to inform policy. For the survey, 45 poultry farms and 10 major dealers of poultry inputs within the Dormaa District were randomly selected. Primary data were obtained through questionnaire administration, semi-structured interviews and observations. Secondary data on poultry farming were also obtained from the District Veterinary Services Division, the District Assembly and the Poultry Farmers' Association. The survey revealed that the major challenges encountered by the poultry farmers included; financing, diseases and absence of electricity for operations in most farms (84.4%). The presence of feed processing mills, poultry input shops and availability of organised markets served as prospects that could be harnessed to boost the growth of the poultry industry in the district.

“…The data presented in this study show that none of the 12 isolated samples were pathogenic, with ICPI < 0.70; similar results were obtained by Orsi et al (18,20). The results obtained in the present study showed that non-export industrial poultry from the four studied Brazilian federative units nonpathogenic Newcastle disease virus was found, as established in the standard postulated by  the International Animal Health Code.…”

“…In this study, we isolated NDV in healthy birds with a frequency from 0 to 1.7% for flocks and from 0% to 100% by geographic region; similar results were obtained by Orsi et al (20) with the percentage of isolation per flocks of 0.44% and 53.3% in the Southeastern region. However, another research by Orsi et al (18) resulted in 7.6% per flock and 58.4% in the Southeastern region.…”

“…Viral isolates were identified as Newcastle disease virus and their biological characterization showed intracerebral index range between 0.0 and 0.54, as shown in Table 3. From the isolates obtained, 91.7% had ICPI from 0.0 to 0.40, identifying the vaccine strains -Ulster 2 C, V4 Queensland, B1 and La Sota (5), this result is similar to that obtained by Orsi et al (20). The most frequently used vaccines in Brazil are La Sota and B1, which present ICPI levels of 0.4 and 0.2, respectively (1,5).…”

Pathological and molecular findings of avian avulavirus type 1 outbreak in pigeons (Columba livia) of southern Brazil

The Newcastle disease, caused by avian avulavirus type 1 strains (APMV-1) is an important avian disease involved into high rates of mortality and economic losses. Several outbreaks have been reported over the last 30 years in Columbiformes in different parts of the world, caused by a adapted variant strain of AAvV-1, called pigeon paramyxovirus type 1 (PPMV-1). A high mortality associated with an outbreak was analyzed in free-living pigeons (Columba livia) in a public square in Porto Alegre in Southern Brazil. A total of 24 pigeons moribund or freshly dead, within five weeks interval were submitted to necropsy, histopathological, immunohistochemical (anti-Newcastle), and RT-PCR followed by sequencing of the amplification products analysis. They presented neurological signs, non-suppurative encephalitis and encephalomyelitis, and mononuclear inflammatory infiltrate in different organs. Immunohistochemical analysis in nine pigeons tissue showed that anti-Newcastle was expressed in brain, kidney, liver and pancreas. The RT-PCR test for the M protein of Newcastle disease virus was positive in six pigeons. The differential diagnosis of Influenza, West Nile, Mycoplasma gallisepticum and Mycoplasma synoviae in all pigeons presented negative results. The sequence of amino acids in the cleavage site region of the F protein was 112RRQKRF117 classifying the strain as virulent. The phylogenetic analysis classified this virus strain into Class II and VI genotype.
