“…It is therefore not surprising that the prevalence of NDV shedding in chickens is higher than in ducks as reported in this study. Okoroafor et al (2020) reported lower NDV prevalence in turkeys than in village chickens, which shows the severity of the virus in village chickens than in turkeys, but turkeys are likely to be the source of the infection for other species, especially chickens. Other researchers have compared NDV shedding from oropharyngeal and cloacal routes of different breeds of poultry.…”

Newcastle Disease (ND) has been considered as a threat to poultry industry worldwide. Despite different strategies aimed at controlling ND in Nigeria, the severe form of the disease continues to occur even in vaccinated poultry farms. The disease is transmitted primarily through contact with infected or carrier birds. Newcastle disease virus (NDV) shedding through either cloacal or oropharyngeal route play a critical role in the spread of NDV. However, there is paucity of information on the comparative contribution of these routes to NDV shedding. In this study, a total of 256 swab samples were collected from cloacal (n = 128) and oropharyngeal (n = 128) routes from broilers, layers, village chickens, ducks and turkeys that were naturally exposed to NDV. Haemagglutination (HA) and haemagglutination inhibition (HI) tests were carried out to detect the presence of the virus. The results of NDV shedding from cloacal and oropharyngeal routes were compared. The result showed a higher prevalence (42.2%) of NDV shedding from cloacal route when compared with oropharyngeal route (26.6%). In addition, village chickens showed a higher prevalence (43.8%) of NDV shedding when compared with all other breeds sampled. Furthermore, birds at 6 weeks shed higher NDV (66.6%) than the birds of other ages. Therefore, the result of this study showed that the prevalence of NDV shedding was higher in village chickens via cloacal route. There is a need to quantify the amount of NDV shedding in both cloacal and oropharyngeal routes from these breeds of poultry so as to evaluate the viral infective dose.

Biological denitrification is an efficient and low-cost method to treat wastewater, and it has been shown that growth promoters can regulate the metabolism of microorganisms. This study aimed to investigate the effects of gibberellic acid, naphthalene acetic acid, compound sodium nitrophenolate, and diethyl aminoethyl hexanoate on the growth and denitrification process of denitrifying microorganisms and to examine the associated mechanisms. All four tested growth promoters did not affect the growth of the strain Q1; further, compound sodium nitrophenolate could significantly improve the bacterial denitrification efficiency and showed an increase in the removal rate of 13.08% in 72 h. The addition of 15 mg/L compound sodium nitrophenolate increased the removal rate of strain Q1 by 25.88% at 72 h, significantly improving the efficiency of reducing the chemical oxygen demand of the effluent. Transcriptome analysis identified 1664 differentially expressed genes (573 upregulated and 1091 downregulated genes) in the strain Q1 treated with compound sodium nitrophenolate. Nitrate reductase and nitrate transporter, which are two key enzymes related to the nitrate reduction pathway, were found to be upregulated during the denitrification process. Compound sodium nitrophenolate has promising applications in high-salt and high-nitrogen wastewater treatment.
