The relevance of bacteriophage therapy in the era of antibiotic resistant bacteria
Against a backdrop of rising antibiotic resistance and a dwindling pipeline of new antibacterial drugs, this thesis set out to examine the potential of bacteriophage (phage) therapy as an alternative or complementary means of treating bacterial infection. Phage therapy is used as a frontline …

An assessment of antibiotic resistant bacteria in biosolid used as garden fertilizer
… from the Cheney Wastewater Treatment Plant and antibiotic resistant gram negative bacteria were isolated from it. Bacteria isolated from these samples were resistant to tetracycline, ampicillin, streptomycin, kanamycin and chloramphenicol. Tetracycline resistant bacteria were isolated on …

Presence of Antibiotic Resistant Salmonella spp. in Backyard Poultry and Their Environment
… for antimicrobial sensitivity to 6 standard antibiotics: Ampicillin, Bacitracin, Erythromycin, Gentamicin, Penicillin, and Tetracycline, at the standard disk concentration levels. The Kirby-Bauer antimicrobial sensitivity test determined that 12 different profiles emerged from the …

Persistence of Culturable Antibiotic Resistant Fecal Coliforms From Manure Amended Vegetable Fields
The reduced efficacy of antibiotics in treating common infections is one of the most pressing health concerns of the 21st Century. Increasing evidence links the widespread use of antibiotics in livestock production to the transfer of bacteria carrying antibiotic resistance genes to the broader …

Investigation of the prevalence of antibiotic resistant bacteria and their genes in wastewater
Antibiotics are therapeutic agents commonly used in the treatment of infections caused by microorganisms. Due to the increased demand of antibiotics, they have become environmental pollutant to both water and soil. This have caused adverse effects to human, animals, aquatic ecosystem and in the …

Molecular Profiling of Antibiotic Resistant Bacteria and Genes in Raw and Drinking Water
Antibiotic resistant bacteria and antibiotic resistant determinants are regarded as emerging public health threats in drinking water systems. Heterotrophic Plate Count bacteria in distribution pipes are used as direct parameters to assess the conditions of water in distribution systems. Moreover, …

Assessing the Presence of Antibiotic-Resistant Enterococcus in Reclaimed Water Used for Spray Irrigation
… We detected total enterococci and vancomycin-resistant enterococci (VRE) in 68% (27/40) and 8% (3/40), respectively, of all SI samples. VRE and vancomycin-intermediate enterococci (VIE) represented 2% (1/41) and 10% (4/41), respectively, of the total enterococci recovered from all SI sites. …

Towards the post-antibiotic era: The role of antibiotic resistant enterococci in different sources
L esplosione del fenomeno dell antibiotico resistenza (AR) si configura come un fenomeno globale. Sebbene i batteri AR sia stati per lungo tempo esclusivamente associati ad ambienti ospedalieri e/o sanitari, nell ultimo decennio sono stati isolati sempre più frequentemente, in numerosi altri …

Medical Microbiology: Discovery of New Antimicrobial Drugs to Treat Clinically Relevant Antibiotic Resistant Pathogenic Bacteria
… that may result from continued spread of drug resistant infections. These actions include discovery of new antibiotics and community engagement in AMR. Natural product screening methods are arguably the most efficient way to identify novel antibiotics, but can be frustrated by the repeated …

Impact of Manure Land Management Practices on Manure Borne Antibiotic Resistant Elements (AREs) in Agroecosystems
Rising global antibiotic resistance has caused concerns over sources and pathways for the spread of contributing factors. Majority of the antimicrobials used in the U.S. are involved in veterinary medicine, primarily with livestock rearing. Animal manure land application integrates livestock …

Effect of Composting on the Prevalence of Antibiotic Resistant Bacteria and Resistance Genes in Cattle Manure
Antibiotic resistance is a growing human health threat, making infections more difficult to treat and increasing fatalities from and cost of treatment of associated diseases. The rise of multidrug resistant pathogens threatens a return to the pre-antibiotic era where even the most common infections …

The Effect of Thermophilic Anaerobic Digestion on Ceftiofur and Antibiotic Resistant Gene Concentrations in Dairy Manure
The prevalence of antibiotics on farms for therapeutic and prophylactic use in animals can cause negative effects on biomethane production during anaerobic digestion. Previous literature has found decreased biomethane production rates from a variety of antibiotics, but biogas inhibition differs …

Antibiotic resistant and xenobiotic degrading bacteria that shape the microbiota of the vectors Aedes aegypti & Culicoides sonorensis
… of permethrin-degrading, antimicrobial-resistant (AMR) bacteria in both mosquito and midge microbiota highlights microbiome-associated insecticide resistance and suggests that these vectors may act as reservoirs that potentially aid in the environmental dissemination of …

Effect of Standard Post-harvest Interventions on the Survival and Regrowth of Antibiotic-Resistant Bacteria on Fresh Produce
… for fresh vegetables to serve as a vehicle for antibiotic -resistant bacteria is poorly understood. Antibiotics and antibiotic-resistant bacteria have been shown to persist in manure of animals administered antibiotics, and in compost generated from this manure, where there is the potential for …

Synthesis and Characterisation of Metallic Nanoparticles from Medicinal Plant Extracts and their Application in combating Antibiotic-Resistant Bacterial Pathogens
Background: The rise of antibiotic-resistant (ABR) bacterial pathogens is a major global health concern, especially in the case of respiratory tract infections (RTIs), which can make treatment more difficult. According to statistics, more than 2 million lives were lost due to ABR bacterial …

Fate and transport of antibiotic resistant bacteria and resistance genes in artificially drained agricultural fields receiving swine manure application
… led to increasing concerns regarding levels of antibiotics and antibiotic resistant bacteria in their excrement. Application of swine manure to agricultural fields as fertilizer creates a pathway for antibiotic resistant bacteria and their associated resistance genes to enter the environment. …
