Background and Aim: The indiscriminate use of antimicrobials in livestock farming has contributed to the emergence antimicrobial-resistant pathogens, posing a significant public health challenge. This study aimed assess prevalence antimicrobial resistance (AMR) profiles Salmonella spp. isolated from swine poultry small- medium-scale farms Cambodia. Materials Methods: A total 638 fecal samples (273 rectal swabs 365 cloacal poultry) were collected five provinces Cambodia June September 2021....
Misuse, overuse, and missed prescription of antimicrobials are the driving factors to antimicrobial resistance (AMR) leading a globally increasing public health concern. This study was conducted assess current knowledge, attitudes, practices (KAP) village animal workers (VAHWs) veterinary drug retailers (VDRs) on use (AMU) (AMR). The sample size calculated following [1]. KAP data were scored categorized Bloom's cut-off score. A total 108 populations (66 VAHWs 42 VDRs) purposively surveyed...
The development of antimicrobial resistance (AMR) due to over or misuse antibiotics/antimicrobials is a globally increasing public health concern. This study was conducted assess the current knowledge, attitudes, and practices (KAP) swine poultry producers on use (AMU) (AMR). A total 254 5 provinces in Cambodia were purposively surveyed using validated KAP questionnaires, useful tool for promoting rational antimicrobials livestock. Collectively, this found out that livestock have low level...
Riemerella anatipestifer (RA) is an economically important pathogen in the duck industry worldwide that causes high mortality and morbidity infected birds. We previously found upregulated IL-17A expression ducks with RA participates pathogenesis of disease, but this mechanism not linked to IL-23, which primarily promotes Th17 cell differentiation proliferation. RNA sequencing analysis was used study investigate other mechanisms upregulation infection. A possible interaction IL-26 IL-17...
African swine fever (ASF) is a contagious hemorrhagic disease affecting both domestic and wild pigs with high mortality rate severe socio-economic losses. Due to the virus' potential ability remain infectious in suitable conditions environments, it imperative identify risk factors that may contribute its transmission. The Philippines' current ASF surveillance relies on pig blood samples. With this very limited epidemiological data, include raw meat processed pork products due transmission...
R. anatipestifer (RA) is one of the most harmful bacterial pathogens affecting duck industry, and infection associated with production proinflammatory cytokines, including IL-17A. Another cytokine, IL-23, critical for development Th17 cells, which produce IL-17. However, IL-23 roles have not been studied in this infection. Here, we describe identification mRNA expression analysis IL-23p19 (duIL-23p19) splenic lymphocytes macrophages stimulated killed RA spleens RA-infected ducks. Expression...
Riemerella anatipestifer is one of the most devastating pathogens affecting global duck farms. Infection involved in secretion proinflammatory cytokines, including interleukin- (IL-) 17A. During immune response to infection, IL-22 and IL-17A are often produced concurrently at high levels inflamed tissues. Little known about (duIL-22) during R. infection. We describe characterization duIL-22 its mRNA expression analysis splenic lymphocytes macrophages treated with heat-killed spleens livers...
Coccidiosis in chickens is an intestinal parasitic disease caused by protozoan parasites named Eimeria spp. In some infections, lymphocytes are known to highly express chicken NK-lysin (cNK-lysin), antimicrobial peptide with anticoccidial activity. Therefore, this study aims investigate the expression of cNK-lysin E. necatrix-infected and its role necatrix infection. The transcript was significantly increased sporozoites-treated lymphocytes. infection, induced but not spleen. recombinant...
African swine fever (ASF) is a contagious transboundary disease that poses significant threat to the industry. As an archipelago, Philippines has geographic advantage in reducing ASF transmission risk. However, control efforts remain challenging due disease's complex epidemiology, lack of effective treatment, and vaccine availability. risk evaluation currently includes positive cases, population density, pork production volume, but potential role contaminated commodities remains unexplored....
Three parameters, body weight gain (BWG), intestinal lesion score (LS) and fecal oocyst shedding, were compared in broilers infected with major parasitic species; Eimeria acervulina, E. maxima, tenella. First, two- three-week-old chickens infection showed LS of approximately 3, but two-week-old more correlated BWG. Second, significant differences BWG observed between male female challenged Eimeria. Finally, maxima-infected among three species a higher relationship LS, suggesting...
3,3’-Diindolylmethane (DIM) is found in cruciferous vegetables and used to treat various inflammatory diseases because of its potential anti-inflammatory effects. To investigate effects DIM Riemerella anatipestifer- infected ducks which induce upregulation cytokines, were treated orally with at dose 200 mg/kg/day the following day R . anatipestifer Infected DIM-treated exhibited 14% increased survival rate significantly decreased bacterial burden compared untreated ducks. Next, effect on...
Abstract Background: Avian coccidiosis is a major disease within the poultry industry caused by species of Eimeria, an intestinal protozoan parasite. Body weight gain, lesion score, and fecal oocyst shedding are parameters that have been used to assess protective effects various treatments in Eimeria -infected chickens. The objective this study was compare aforementioned broiler chickens infected with parasitic such as E. acervulina , maxima tenella . Results: results body showed similar...
