ABSTRACT: The current study investigated and compared the antibacterial activity of common kitchen spices; Ginger, Turmeric, Bay leaf, and Coriander, against Escherichia coli, Staphylococcus aureus, Salmonella Typhi, and Pseudomonas aeruginosa. The antibacterial activity of different spices was calculated by the agar well cup plate method. The concentrations, 75%, 50%, and 25%, were made for all the test spices by diluting the concentrated extract with appropriate volumes of sterile distilled water. Ginger and turmeric are effective against all four pathogens. Ginger reported maximum activity against Escherichia coli with 14.5 zones of inhibition at 100% concentration. Bay leaf showed comparatively good antibacterial activity at higher concentrations and possessed maximum antibacterial activity against Salmonella Typhi with 15.4 zones of inhibition at 100% concentration. Coriander unveils comparatively good antibacterial activity against Escherichia coli and Staphylococcus Aureus at higher concentrations. It exhibits maximum antibacterial activity against Pseudomonas aeruginosa with an 18.7 mm zone of inhibition at 100% concentration. Coriander didn’t reveal activity against Salmonella Typhi at any concentration. The results of the present study are quite promising. All four spices exhibited antimicrobial activity against most pathogens, but the antimicrobial activity varies widely, depending on the type of spices and microorganisms.

INTRODUCTION: Spices are defined as any dried, fragment or aromatic plant substance that contributes flavour in whole, broken, or ground form Spices are the potential source of natural products and naturally derived compounds. Spices have been defined as plant substances from the indigenous or exotic origin, aromatic or with strong taste, used to enhance the taste of foods.
Spices include leaves (bay, mint, rosemary, coriander, laurel, and oregano), flowers (cloves), bulbs (garlic, onion), fruits (cumin, red chilli, and black pepper), stems (coriander, cinnamon), rhizomes (ginger) and other plant parts 1. Although spices have been well known for their medicinal, preservatives, and antioxidant properties, they have been currently used with the primary purpose of enhancing the flavour of foods rather than extending the shelf-life of foods.

It is not only beneficial when consumed fresh; adding coriander seeds to your daily food can also be very healthy. Coriander seeds have anti-oxidant properties and dietary fiber that advance the healthy working of the liver and facilitate bowel moments. They help in the generation of digestive compounds and juices that facilitate the procedure of digestion 8.
Bacteria Used For Determination of Antibacterial Activity of Spices: Bacteria or culture used in the experiment of determination of antibacterial activity of spices are ATCC (American Type Culture Collection culture type ATCC or the American type culture collection is a non-profit organization which collects stores and distributes standard reference microorganism, cell lines and other material for research and development. Established in 1925 to serve as a national center for depositing and distributing microbiological specimens. ATCC has since grown to distribute in over 150 countries. It is now the largest general culture collection in the world.
The four specimens from ATCC culture were used to determine of antibacterial activity of different types of spices; they are:
Escherichia coli, Staphylococcus aureus, Salmonella Typhi, Pseudomonas aeruginosa
Escherichia coli (E. coli): Escherichia coli, also known as E. coli, was isolated by Escherich in 1885 from faeces of humans and named after him. E. coli is a Gram-negative, facultatively anaerobic, rod-shaped, coliform bacterium of the genus Escherichia commonly found in the lower intestine of warm-blooded animals.
Virulence Factors of Escherichia Coli: Somatic (O) antigens: - the gram-negative lipopoly saccharide comprises of lipid A, core polysaccharide and repeating chain of carbohydrates called somatic (O) antigens. Capsular/ surface (K) antigens: - K-antigens of E. coli are acidic polysaccharides and cover the O antigens. The K-antigen act as a virulence factor by preventing phagocytosis and antibody-mediated killing. Flagellar (H) antigens: - H-antigens are located on flagella and are thermolabile protein 9, 10.
Staphylococcus aureus: Staphylococcus aureus was first isolated by Pasteur in 1880 A.D. and named by Sir Alexander Ogston from “staphyle”- a bunch of groups, “kokkos”- berry (grain). Staphylococcus is the major human pathogen responsible for various pathogenic (pus-forming) infections and toxins-mediated infections. 10-40% of normal humans carry Staphylococcus aureus in their nostril. Staphylococcus aureus is a skin commensal associated with the prosthetic device and UTI 11.
Virulence Factors of Staphylococcus aureus:
Cell Wall Components:
- Polysaccharide capsule inhibits phagocytosis.
- Peptidoglycan activates complement, IL-1,
- Teichoic acid species-specific, mediate binding to fibronectin.
- Protein A It binds to Fc region of IgG & complement, exerting an anti-opsonin effect.
- Fibronectic binding protein (FnBP): promote binding to mucosal cells and tissue matrices.
- Clumping factors FnBP enhances clumping of the organism in the presence of plasma 12.
Enzymes:
- Catalase enzyme conversion of H2O2 into water and oxygen.
- Coagulase enzyme and clumping factors an enzyme like protein that clots oxalated or citrated plasma.
- Other enzymes hyaluronidase, staphylokinase, proteinases, lipases,
- Toxins Exotoxins & Enterotoxins
Salmonella typhi: Salmonellae are primarily intestinal parasites of humans and many animals, including birds, and are widely distributed in water and soil, where they do not multiply significantly. It is a Gram-negative, non-sporulating, non-capsulated rod, motile with flagella and facultative anaerobe. Salmonella typhi is bacteria that infect the intestinal tract and blood. The disease caused by Salmonella typhi is known as typhoid fever. Salmonella typhi is spread by the faecal-oral route 13.
Virulence Factors of Salmonella typhi: Salmonella possesses the following types of antigens or virulence factors; they are. Somatic (O) antigens the gram-negative lipopolysaccharide comprises of lipid A, core polysaccharide, and a repeating chain of carbohydrates called somatic (O) antigens.
Capsular/ surface (K) antigens K-antigens of Salmonella typhi are acidic polysaccharides and cover the O antigens. The K-antigen act as a virulence factor by preventing phagocytosis and antibody-mediated killing. Flagellar (H) antigens H-antigens are located on flagella and are thermolabile protein 14.
Pseudomonas aeruginosa: It is a common encapsulated, Gram-negative, rod-shaped bacterium that can cause disease in plants and animals, including humans. A species of considerable medical importance, Pseudomonas aeruginosa is a multidrug-resistant pathogen recognized for its ubiquity.
It’s intrinsically advanced antibiotic resistance mechanisms and its association with serious illnesses-hospital acquired infections such as ventilator-associated pneumonia and various sepsis syndromes.
The organism is considered opportunistic in so far as serious infection often occurs during existing diseases or conditions, most notably cystic fibrosis and traumatic burns; it generally affects the immune-compromised but can also infect the immune-competent. It is found in soil, water, skin flora, and most manmade environment throughout the world 15.
Virulence factors of Pseudomonas aeruginosa: Pseudomonas aeruginosa possess.
- Both pilin and non-pilus adhesion are important for attachment
- Lipopolysaccharide (LPS): endotoxin
- Flagella
- Anti-microscopic resistance
- Iron capturing ability
Antibiotic Susceptibility Test (AST): Antibiotic susceptibility test or Antibiotic sensitivity testing is the measurement of the susceptibility of bacteria that may have resistance to some antibiotics; sensitivity results can allow a clinician to change the choice of antibiotics from empiric therapy, which is when an antibiotic is selected based on clinical suspicion about the site of an infection and common causative bacteria 16, 17. Sensitivity testing usually occurs in a medical laboratory. It may be based on culture methods that expose bacteria to antibiotics or genetic methods that test to see if bacteria have genes that confer resistance culture method often involve measuring the diameter of without bacterial growth called zone of inhibition. Antibiotics susceptibility test is done when used antibiotics, and Antibiotics is a substance produced wholly or partly by microorganisms which is small concentration inhibits the growth of other microorganisms 18, 19.
MATERIALS AND METHODS:
Research Design: This study was a descriptive type of research design and qualitative nature. The research work was mainly focused on the antibacterial activity of four spices against common pathogenic bacteria from American type culture collection (ATCC).
Data Analysis: In this study, the method of data collection was observational and experimental for both qualitative and quantitative data. The collected data and information were processed, tabulated, and analyzed quantitatively by using different statistical methods such as tables and percentages.
Laboratory Procedure:
Collection of Spices: The fresh spices for sampling were collected from the Raj biraj local market. This experimental test was carried out for different concentrations of spice extract on different bacterial isolates from ATCC.
Preparation of Spices Extract: New spices have been purchased from the local market. The spices were, if possible, cleaned, decaled, and washed in sterile distilled water. Around 100 g of any washed spice was crushed with mortar and pestle to obtain the spice extracts. The extracts were sieved and sterilized using a membrane filter (0.45-micron sterile filter) via a fine mesh fabric 20.
Preparation of Different Concentration of Extract: The filtrate extract obtained was about 10 ml for each species and these extract was considered the 100% concentrations of the extract. The concentrations, 75%, 50% and 25% were made for all the test spices by diluting the concentrated extract with appropriate volumes of sterile distilled water. For 75% concentration, 2.5 ml of distilled water were poured in 7.5 ml of filtrate extract. Similarly, for 50% concentrations, 5ml of distilled water were poured in 5ml of filtrate extract, whereas for 25% concentrations, 7.5 ml of distilled water were poured into 2.5 ml of filtrate extract 21, 20. All the stock solutions were collected in a small sterile container and stored at the refrigerator for preservation.
Collection and Maintenance of Culture: All the test organisms (ATCC) were collected from the authorized place. These organisms were first inoculated into 10 ml of sterile nutrient broth to revive, then were sub-cultured on NA (Nutrient agar) for E. coli and Pseudomonas aeroginosa, MSA (Mannitol salt agar) for Staphylococcus aureus and SS agar (Salmonella-Shigella agar) for Salmonella typhi and were tested for their purity by examining their morphological characteristics (by gram staining tests) and biochemical tests. Purely isolated colony of each organism was incubated at 37 ℃ for 4 h to bring them into log phase 22.
Antibacterial Activity Testing Using Agar Well Method (Cup Plate Method): Using a sterile cotton swab, the nutrient broth culture was swabbed on the surface of sterile Mueller-Hinton Agar (MHA) plates. Agar wells were prepared with the help of a sterilized cork borer with 6 mm diameter. Using a micropipette, 50 microlitres of different concentrations of spices extracts (100%, 75%, 50%, and 25%) were added to different wells in the plate. The plates were incubated in an upright position at 37 ºC for 24 h.
The diameter of inhibition zones was measured in mm, and the results will be recorded. The inhibition zones with a diameter less than 7 mm were considered as having no antibacterial activity 23.
Preparation of Control Plate: One control plate was prepared in each experiment by agar well diffusion to sterilized distilled water instead of ginger turmeric, bay leaf, and coriander extract (Kirby Bauer Technique). The control plate was essential and very important to measure and determine whether the spice extract was the substance that will kill the bacteria and not cause other elements and factors. The inhibitory effect of these spices was compared with that of 5 control antibiotics (chloramphenicol, ciprofloxacin, nalidixic acid, streptomycin, and tetracycline).

CONCLUSION: Spices are food additives that have been shown to be medicinal, with special herbal and aromatic flavourings. This is especially of urgent concern when considering the growth rate of multi-resistant bacterial strains worldwide. The above finding offered the basis for the therapeutic potential of spices.
The antibacterial activity of the different spices was measured using the agar cup plate process. The findings of this study are very promising for all four spices with antimicrobial activity against most pathogens, but antimicrobial activity varies significantly depending on the type of spice and microorganism.
According to the present study, Ginger and Turmeric are effective against all four pathogens (Escherichia coli, Staphylococcus aureus, Salmonella Typhi, Pseudomonas aeruginosa). Bay leaf showed comparatively good antibacterial activity at higher concentrations. Coriander exhibits the maximum activity against Pseudomonas aeruginosa, but no activity against Salmonella Typhi at any concentration.
