Molecular characterization, antibiotic resistant pattern and biofilm forming potentiality of bacterial community associated with Ompok pabda fish farming in southwestern Bangladesh. Microb Pathog 2024:106818. [PMID: 39047804 DOI: 10.1016/j.micpath.2024.106818] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2024] [Revised: 07/15/2024] [Accepted: 07/19/2024] [Indexed: 07/27/2024]
Abstract
Ompok pabda is gaining popularity in the aquaculture industry due to its increasing demand; however research on microbial diversity and antibiotic susceptibility remains limited. The present study was designed to identify the bacterial pathogens commonly found in the pabda farming system with their biofilm forming potential and antibiotic susceptibility. Different bacterial strains were isolated from water, sediments and gut, gill of pabda fish and the isolates were identified based on their morphological traits, biochemical and molecular analysis. Antibiotic susceptibilities, antibiotic resistance gene determination and biofilm formation capabilities were evaluated by disc diffusion method, PCR amplification and Microtiter plate (MTP) assay, respectively. The respective isolates of gill and gut of pabda aquaculture and their environments were: Exiguobacterium spp. (25%), Enterococcus spp. (20%), Bacillus spp. (10%), Acinetobacter spp. (10%), Enterobacter spp. (10%), Aeromonas spp. (10%), Lactococcus spp. (5%), Klebsiella spp (5%) and Kurthia spp. (5%). Antibiotic resistance frequencies were found to be relatively high, especially for trimethoprim (95%), sulfafurazole (75%), ampicillin (60%), amoxicillin-clavulanic acid (55%), and cephradine (50%). 30% isolates were categorized as DR bacteria followed by 30% isolates were MDR bacteria and 40% were classified as XDR bacteria. Moreover, 4 antibiotic resistant genes were detected with sul1 (30%), dfrA (10%), tetC (40%), and qnrA (5%) of isolates. Based on the microtiter plate method, 20%, 25%, and 30% of isolates were found to produce strong, moderate, and weak biofilms, respectively. The findings suggest that biofilm forming bacterial strains found in O. pabda fish farm may be a potential source of numerous antibiotic-resistant bacteria. The study sheds new light on antibiotic resistance genes, which are typically inherited by bacteria and play an important role in developing effective treatments or control strategies.

The Effect of Bifidobacterium animalis subsp. lactis MN-Gup on Glucose Metabolism, Gut Microbiota, and Their Metabolites in Type 2 Diabetic Mice. Nutrients 2024; 16:1691. [PMID: 38892624 PMCID: PMC11174421 DOI: 10.3390/nu16111691] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2024] [Revised: 05/26/2024] [Accepted: 05/27/2024] [Indexed: 06/21/2024] Open
Abstract
Probiotics have garnered increasing attention as a potential therapeutic approach for type 2 diabetes mellitus (T2DM). Previous studies have confirmed that Bifidobacterium animalis subsp. lactis MN-Gup (MN-Gup) could stimulate the secretion of glucagon-like peptide-1 (GLP-1) in NCI-H716 cells, but whether MN-Gup has a hypoglycemic effect on T2DM in vivo remains unclear. In this study, a T2DM mouse model was constructed, with a high-fat diet and streptozotocin in mice, to investigate the effect of MN-Gup on diabetes. Then, different doses of MN-Gup (2 × 109 CFU/kg, 1 × 1010 CFU/kg) were gavaged for 6 weeks to investigate the effect of MN-Gup on glucose metabolism and its potential mechanisms. The results showed that a high-dose of MN-Gup significantly reduced the fasting blood glucose (FBG) levels and homeostasis model assessment-insulin resistance (HOMA-IR) of T2DM mice compared to the other groups. In addition, there were significant increases in the short-chain fatty acids (SCFAs), especially acetate, and GLP-1 levels in the MN-Gup group. MN-Gup increased the relative abundance of Bifidobacterium and decreased the number of Escherichia-Shigella and Staphylococcus. Moreover, the correlation analysis revealed that Bifidobacterium demonstrated a significant positive correlation with GLP-1 and a negative correlation with the incremental AUC. In summary, this study demonstrates that Bifidobacterium animalis subsp. lactis MN-Gup has significant hypoglycemic effects in T2DM mice and can modulate the gut microbiota, promoting the secretion of SCFAs and GLP-1.

Abstract
The present study was conducted to evaluate the effects of dietary Macleaya cordata extract (MCE) supplementation on growth performance and intestinal health of American eels (Anguilla rostrata) farmed in intensive system. A total of six cement tanks of fish were randomly divided into a control group fed a commercial diet and an MCE group fed the commercial diet with 100 mg/kg MCE, respectively. There were three replicates in each group. The results suggested that 100 mg/kg MCE could improve the growth performance and intestinal health of the American eels by strengthening the barrier function and antioxidative ability in the intestine and beneficially modulating intestinal microbiota with the higher relative abundance and more species of the potential probiotics and the lower relative abundance of potentially pathogenic bacteria.

Punicalagin: a monomer with anti-Eimeria tenella effect from Fruit peel of Punica granatum L. Poult Sci 2022; 101:102100. [PMID: 36055031 PMCID: PMC9449852 DOI: 10.1016/j.psj.2022.102100] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Revised: 07/20/2022] [Accepted: 07/26/2022] [Indexed: 11/30/2022] Open
Abstract
Poultry production was long plagued by coccidiosis, and the development of alternative therapies will make practical sense. In this work, 2 battery experiments were designed. In battery experiment 1, the best effect of 7 anticoccidial herbs (Sophora japonica Linn, Citrus aurantium L, leaf of Acer palmatum, bark of Magnolia officinalis, fruit peel of Punica granatum L., Eclipta prostrata L., and Piper sarmentosum Roxb.) against Eimeria tenella infection of 21-day-old male Chinese Guangxi yellow-feathered chickens were screened out by clinic indexes (bloody feces scores, cecal lesion scores, oocysts output, relative weight gain rate, and survival rate). According to the results from battery experiment 1 and other literature research, we selected 2 monomers which were extracted from fruit peel of Punica granatum L. for further battery experiment 2 which were similar with battery experiment 1. Clinic results showed that Punicalagin had better anticoccidial effect than Ellagic acid. The anticoccidial mechanism exploration results of Elisa, antioxidant test, and pathological observation showed that Punicalagin reduced the cecal inflammation, improved the expression of immunoglobulin in cecal tissue, improved cecal integrity, and restored its REDOX state. Results of 16S rRNA sequencing analysis showed that Punicalagin also maintained the fecal flora health during E. tenella infection through insignificantly increasing the proportion of Lactobacillus and Faecalibacterium as well as significantly reducing the proportion of pathogenic bacteria, Escherichia–Shigella. RNA-Seq analysis results suggested that Punicalagin may play a role in controlling E. tenella infection by interaction with cytochrome P450 family enzymes. Overall, Punicalagin has promising potential as an alternative therapy for chicken Eimeria tenella infection.
