Anti-urinary tract infection activity of selected herbal extract towards isolated Kosakonia cowanii (OQ 073698)

Abstract

Urinary Tract Infection (UTI) is one of the most common types of infection caused by the gastrointestinal tract of humans. UTI is the most common in women because a women''s urethra is shorter. In the present investigation, four UTI-causing bacteria were isolated on MacConkeys as well as on UTI agar media which is selective for UTI pathogens only. The isolated bacteria were tested for antibiotic resistance towards the selective antibiotics Ampicillin (10µg), Penicillin (10µg), and Chloramphenicol (30µg). Based on antibiotic resistance and morbific nature, the organism was screened. On the basis of morphological, biochemical characteristics and the 16S r-RNA sequencing method the organism was identified as Kosakonia cowanii. The nucleotide sequence was deposited to NCBI and received a unique accession number (OQ 073698). The anti-UTI activity was performed towards selective medicinal herbs by using ethanol, methanol and water as solvent extraction methods. The Embilica officinalis ethanolic extract (1 mg/ml) and standard antibiotic chloramphenicol showed 1.8 mm zone of inhibition against K. cowanii (OQ 073698). From the present study, it is concluded that E. officinalis ethanolic extract was effective to treat UTI infection. Another core finding from the present study includes - an isolated pathogen that was earlier resistant to ampicillin but when combines with E. officinalis and Boerhavia diffusa ethanolic extracts separately showed 2.0 mm zone of inhibition.
