Pérez-Delgado O, Espinoza-Culupú AO, López-López E. Antimicrobial Activity of Apis mellifera Bee Venom Collected in Northern Peru. Antibiotics (Basel) 2023; 12:antibiotics12040779. [PMID: 37107142 PMCID: PMC10135115 DOI: 10.3390/antibiotics12040779] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Revised: 04/10/2023] [Accepted: 04/16/2023] [Indexed: 04/29/2023] Open
Abstract
Due to the emergence of microorganisms resistant to antibiotics and the failure of antibiotic therapies, there is an urgent need to search for new therapeutic options, as well as new molecules with antimicrobial potential. The objective of the present study was to evaluate the in vitro antibacterial activity of Apis mellifera venom collected in the beekeeping areas of the city of Lambayeque in northern Peru against Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. Bee venom extraction was performed by electrical impulses and separated using the Amicon ultra centrifugal filter. Subsequently, the fractions were quantified by spectrometric 280 nm and evaluated under denaturant conditions in SDS-PAGE. The fractions were pitted against Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 29213, and Pseudomonas aeruginosa ATCC 27853. A purified fraction (PF) of the venom of A. mellifera and three low molecular weight bands of 7 KDa, 6 KDa, and 5 KDa were identified that showed activity against E. coli with a MIC of 6.88 µg/mL, while for P. aeruginosa and S. aureus, it did not present a MIC. No hemolytic activity at a concentration lower than 15.6 µg/mL and no antioxidant activity. The venom of A. mellifera contains a potential presence of peptides and a predilection of antibacterial activity against E. coli.

Elfadil A, Alzahrani AM, Abdullah H, Alsamhan H, Abujamel TS, Ahmed HE, Jiman-Fatani A. Evaluation of the Antibacterial Activity of Quinoxaline Derivative Compound Against Methicillin-Resistant Staphylococcus aureus. Infect Drug Resist 2023; 16:2291-2296. [PMID: 37095779 PMCID: PMC10122461 DOI: 10.2147/idr.s401371] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Accepted: 04/07/2023] [Indexed: 04/26/2023] Open
Abstract
Background While the frequency of methicillin-resistant Staphylococcus aureus (MRSA) continues to rise globally, there is a fear regarding an increase in vancomycin resistance among S. aureus strains. As far back as the 1960s, MRSA was one of the world's most prevalent antibiotic-resistant bacteria. Among hospitalized patients and community members, MRSA is the cause of a significant number of infections. As a result of its resistance to classical beta-lactam and, in some cases, vancomycin antibiotics, efforts must be made as soon as feasible to find a new approach to fighting MRSA. Purpose This study is designed to evaluate the antibacterial activity of quinoxaline derivative compound against MRSA in comparison with vancomycin as a reference drug. Methods Sixty MRSA isolates were subjected to susceptibility testing by broth microdilution method for quinoxaline derivative compound and vancomycin. Each drug's minimal inhibitory concentration (MIC) was determined and compared. Results Among the sixty MRSA isolates, most of the quinoxaline derivative compound MIC findings (56.7%) were 4 µg/mL compared to vancomycin MIC values (63.3%) of 4 µg/mL. In comparison, 20% of quinoxaline derivative compound MIC readings were 2 µg/mL, while the vancomycin MIC results were 6.7%. However, the overall proportion of MIC readings at ≤2 µg/mL for both antibacterial agents was equal (23.3%). None of the isolates were resistant to vancomycin. Conclusion This experiment revealed that most MRSA isolates were associated with low MICs (1-4 μg/mL) for quinoxaline derivative compound. Overall, the susceptibility of the quinoxaline derivative compound signifies a promising efficacy against MRSA and may set a novel treatment approach.

Antimicrobial sensitivity patterns of Staphylococcus species isolated from mobile phones and implications in the health sector. BMC Res Notes 2021; 14:1. [PMID: 33407799 PMCID: PMC7788780 DOI: 10.1186/s13104-020-05413-7] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Accepted: 12/03/2020] [Indexed: 11/22/2022] Open
Abstract
Objectives The aim of this research was to determine drug sensitivity profiles of Staphylococcus species isolated from mobile phones of students in Microbiology and Biomedical Laboratory Sciences from UZIMA University, Kisumu (Kenya) and the University Colleges Leuven-Limburg, Leuven (Belgium), respectively. Results All mobile phones (16/16, 100%) had gram-positive bacteria. 3/8 (37.5%) mobile devices had Staphylococcus aureus. 2/3 (67%) Staphylococcus aureus strains were resistant to ampicillin, oxacillin, ceftazidime, vancomycin and amoxicillin. Guidelines for disinfection of mobile phones need to be developed urgently to stop transmission of resistant bacteria.

Phenotypic and Genotypic Characterization with MALDI-TOF-MS Based Identification of Staphylococcus spp. Isolated from Mobile Phones with their Antibiotic Susceptibility, Biofilm Formation, and Adhesion Properties. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17113761. [PMID: 32466464 PMCID: PMC7312679 DOI: 10.3390/ijerph17113761] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Revised: 05/15/2020] [Accepted: 05/17/2020] [Indexed: 12/21/2022]
Abstract
Cell phones, smartphones, and tablets are extensively used in social and professional life, so they are frequently exposed to bacteria. The main goal of the present work was to isolate and characterize Staphylococci strains from students’ cell phone mobiles. Subsequently, 24 Staphylococci strains were tested against a wide range of antibiotics, for the distribution of some virulence-related genes and their ability to form biofilm. Staphylococcus spp. were cultured from all studied devices on chromogenic medium and identified using the matrix-assisted laser desorption/ionization (MALDI), time-of-flight (TOF) mass spectrometry (MS) technique (MALDI-TOF-MS). The results obtained showed that S. aureus was the dominant species (19 strains, 79.1%), followed by S. warneri (3 strains, 12.5%), and S. haemolyticus (2 strains, 8.3%). Isolated strains showed high percentages of hydrolytic enzymes production, resistance to many tested antibiotics, and 37.5% expressed the mecA gene. The tested strains were highly adhesive to polystyrene and glass and expressed implicated icaA (62.5%) and icaD (66.6%) genes. All Staphylococcus spp. strains tested were found to possess proteases and the α-hemolysin gene. Our results highlighted the importance of mobile phones as a great source of Staphylococcus spp., and these species were found to be resistant to many antibiotics with multiple antibiotic resistance (MAR) index ranging from (0.444) to (0.812). Most of the studied strains are able to form biofilm and expressed many virulence genes. Phylogenetic analysis based on the phenotypic and genetic characters highlighted the phenotypic and genetic heterogeneity of the S. aureus population studied. Further analyses are needed to elucidate the human health risks associated with the identified Staphylococci strains.
