Phenotypic and genotypic characterization of resistance and virulence in Pseudomonas aeruginosa isolated from poultry farms in Egypt using whole genome sequencing. Vet Microbiol 2024; 292:110063. [PMID: 38554598 DOI: 10.1016/j.vetmic.2024.110063] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Revised: 03/18/2024] [Accepted: 03/19/2024] [Indexed: 04/01/2024]
Abstract
Pseudomonas aeruginosa (P. aeruginosa) is an ESKAPE pathogen that can quickly develop resistance to most antibiotics. This bacterium is a zoonotic pathogen that can be found in humans, animals, foods, and environmental samples, making it a One-Health concern. P. aeruginosa threatens the poultry industry in Egypt, leading to significant economic losses. However, the investigation of this bacterium using NGS technology is nearly non-existent in Egypt. In this study, 38 isolates obtained from broiler farms of the Delta region were phenotypically investigated, and their genomes were characterized using whole genome sequencing (WGS). The study found that 100% of the isolates were resistant to fosfomycin and harbored the fosA gene. They were also resistant to trimethoprim/sulfamethoxazole, although only one isolate harbored the sul1 gene. Non-susceptibility (resistant, susceptible with increased dose) of colistin was observed in all isolates. WGS analysis revealed a high level of diversity between isolates, and MLST analysis allocated the 38 P. aeruginosa isolates into 11 distinct sequence types. The most predominant sequence type was ST267, found in 13 isolates, followed by ST1395 in 8 isolates. The isolates were susceptible to almost all tested antibiotics carrying only few different antimicrobial resistance (AMR) genes. Various AMR genes that confer resistance mainly to ß-lactam, aminoglycoside, sulfonamide, and phenicol compounds were identified. Additionally, several virulence associated genes were found without any significant differences in number and distribution among isolates. The majority of the virulence genes was identified in almost all isolates. The fact that P. aeruginosa, which harbors several AMR and virulence-associated factors, is present in poultry farms is alarming and threatens public health. The misuse of antimicrobial compounds in poultry farms plays a significant role in resistance development. Thus, increasing awareness and implementing strict veterinary regulations to guide the use of veterinary antibiotics is required to reduce health and environmental risks. Further studies from a One-Health perspective using WGS are necessary to trace the potential transmission routes of resistance between animals and humans and clarify resistance mechanisms.

The potential of Spirulina platensis to substitute antibiotics in Japanese quail diets: impacts on growth, carcass traits, antioxidant status, blood biochemical parameters, and cecal microorganisms. Poult Sci 2024; 103:103350. [PMID: 38262339 PMCID: PMC10831102 DOI: 10.1016/j.psj.2023.103350] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 11/29/2023] [Accepted: 12/01/2023] [Indexed: 01/25/2024] Open
Abstract
The development of antibiotic-resistant microorganisms prompted the investigation of possible antibiotic substitutes. As a result, the purpose of the current study is to assess the effect of dietary Spirulina platensis extract as an antibiotic alternative on Japanese quail (Coturnix japonica) growth, antioxidant status, blood parameters, and cecal microorganisms. There was a total of 150 Japanese quails used in this study, divided equally among 5 experimental groups (10 birds per group with 3 replicates): group 1 (G1) received a basal diet without any S. platensis extract, group 2 (G2) received a basal diet supplemented with 1 mL S. platensis extract/kg, group 3 (G3) received a basal diet supplemented with 2 mL S. platensis extract/kg, group 4 (G4) received a basal diet supplemented with 3 mL S. platensis extract/kg, and group 5 (G5) received a basal diet supplemented with 4 mL S. platensis extract/kg from d 7 until d 35. The results showed that compared to the control birds in G1, Japanese quail supplemented with 4 mL of S. platensis extract/kg of diet (G5) had significantly better live body weight, body weight gain, feed intake, feed conversion ratio, digestive enzymes, blood parameters, liver and kidney functions, lipid profile, antioxidant profile, immunological parameters, and cecal microorganism's count. There were no significant changes in the percentage of carcasses, liver, and total giblets among all the 5 groups. Only gizzard percentage showed a significant increase in G2 compared to birds in G1. In addition, intestinal pH showed a significant drop in G2 and G5 compared to birds in G1. After cooking the quail meat, the juiciness and tenderness increased as S. platensis extract levels increased, whereas aroma and taste declined slightly as S. platensis extract levels increased. Furthermore, when a high concentration of S. platensis extract was used, the lightness of the meat reduced while its redness and yellowness increased. The disk diffusion assay showed that S. platensis extract had significant antibacterial activity against Staphylococcus aureus, Listeria monocytogenes, Campylobacter jejuni, and Salmonella typhi, with inhibition zones ranging from 16 to 42 mm. This activity may be attributable to the volatile chemicals in S. platensis extract, of which Geosmin and 2-methylisoborneol are the primary components. In the diet of Japanese quails, it is possible to draw the conclusion that the extract of S. platensis can be utilized as a feed additive and as an alternative to antibiotics.

Ecological prevalence, genetic diversity, and multidrug resistance of Salmonella enteritidis recovered from broiler and layer chicken farms. Poult Sci 2024; 103:103320. [PMID: 38215504 PMCID: PMC10825688 DOI: 10.1016/j.psj.2023.103320] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Revised: 11/17/2023] [Accepted: 11/22/2023] [Indexed: 01/14/2024] Open
Abstract
Salmonella is a significant foodborne pathogen that has a significant impact on public health, and different strains of multidrug resistance (MDR) have been identified in this genus. This study used a combination of phenotypic and genotypic approaches to identify distinct Salmonella species collected from poultry broiler and layer farms, and antibiotic sensitivity testing was performed on these species. A total of 56 Salmonella isolates were serotyped, and phenotypic antibiotic resistance was determined for each strain. The enterobacterial repetitive intergenic consensus polymerase chain reaction (ERIC-PCR) method was also used to provide a genotypic description, from which a dendrogram was constructed and the most likely phylogenetic relationships were applied. Salmonella isolates were detected in 20 (17%) out of 117 samples collected from small-scale broiler flocks. Salmonella isolates were classified as MDR strains after showing tolerance to 4 antibiotics, but no resistance to cloxacillin, streptomycin, vancomycin, or netilmicin was observed. From a genotypic perspective, these strains lack dfrD, parC, and blasfo-1 resistant genes, while harboring blactx-M, blaDHA-L, qnrA, qnrB, qnrS, gyrA, ermA, ermB, ermC, ermTR, mefA, msrA, tet A, tet B, tet L, tet M resistance genes. The genotyping results obtained with ERIC-PCR allowed isolates to be classified based on the source of recovery. It was determined that Salmonella strains displayed MDR, and many genes associated with them. Additionally, the ERIC-PCR procedure aided in the generation of clusters with biological significance. Extensive research on Salmonella serotypes is warranted, along with the implementation of long-term surveillance programs to monitor MDR Salmonella serotypes in avian-derived foods.
