Clinical Significance of Antibiotic Resistance

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...

Combined Effects of Drugs: Synergism

Combined Effects of Drugs: Synergism

Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.
Such synergistic combinations...

Surface Membrane Barriers

Surface Membrane Barriers

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Bacterial Phylum Bacteroidota

Bacterial Phylum Bacteroidota

The phylum Bacteroidota includes over 700 species classified into four primary orders: Bacteroidales, Cytophagales, Flavobacteriales, and Sphingobacteriales. These gram-negative, non-sporulating rods exhibit saccharolytic capabilities and can be aerobic or fermentative, encompassing obligate aerobes, facultative aerobes, and obligate anaerobes. Many species display gliding motility, though some are nonmotile or use flagella. The genus Bacteroides is well-studied due to its significant role in...

Defense Against Bacterial Pathogens

Defense Against Bacterial Pathogens

The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Area of Science:

Phytochemistry
Microbiology
Pharmacology

Background:

The increasing prevalence of antibiotic resistance necessitates the exploration of novel antimicrobial agents.
Plant-derived compounds are a promising source for discovering new therapeutic agents.

Purpose of the Study:

To evaluate the antibacterial potential of chloroform and alcohol extracts from E. plats.
To identify specific bacterial strains susceptible to these plant extracts and isolated compounds.

Main Methods:

Screening of chloroform and alcohol extracts against six bacterial species: Staphylococcus aureus, Escherichia coli, Proteus mirabilis, Salmonella typhimurium, Pseudomonas aeruginosa, and Klebsiella aerogenes.
Fractionation of active extracts using solvent elution (benzene-ethyl acetate, n-butanol).
Isolation and testing of a phenolic compound from an active fraction.

Main Results:

The benzene-ethyl acetate eluate of the chloroform extract demonstrated activity against Escherichia coli, Salmonella typhimurium, and Pseudomonas aeruginosa.
The n-butanol extract of the alcohol extract was effective against Proteus mirabilis and Salmonella typhimurium.
A purified phenolic compound showed activity exclusively against Proteus mirabilis.

Conclusions:

E. plats extracts possess significant antibacterial properties against a range of Gram-negative bacteria.
The isolated phenolic compound warrants further investigation as a potential therapeutic agent for Proteus mirabilis infections.
