Hepatoprotective and cardioprotective effect of Artemisia nilagirica leaf extract on E. coli challenged broiler chicken. Heliyon 2024; 10:e25709. [PMID: 38390080 PMCID: PMC10881339 DOI: 10.1016/j.heliyon.2024.e25709] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 01/25/2024] [Accepted: 02/01/2024] [Indexed: 02/24/2024] Open
Abstract
Artemisia nilagirica is an important medicinal plant found to exhibit several medicinal properties but the use of its leaves for combating E. coli infection has not been scientifically validated in poultry. The present study was conducted to evaluate the protective effects of methanol leaf extract of A. nilagirica (ANE) on E. coli challenged broiler chickens. Three hundred and thirty, day-old broiler chickens, were divided into 6 groups of 55 each, with group EX infected intraperitoneally (I/P) with LD50 dose of 1 × 107 cfu/ml of E. coli; group(s) EA1, EA2 and EA3 infected I/P with 1 × 107 cfu/ml of E. coli and supplemented with ANE @ 0.5, 1.0 and 2.0 g/L of drinking water, respectively; group AX were only given ANE @ 2.0 g/L in the drinking water. ANE treatment was started from day 4 and was continuously given in the drinking water up to day 21. E. coli infection was given to the birds on day 7 of their age. The effect of the plant extract was evaluated on the basis of gross, microscopic and ultrastructural alterations in E. coli challenged broiler chickens. The extract of A. nilagirica was found to show antibacterial, cardioprotective and hepatoprotective properties in a dose-dependent manner on the basis of gross and microscopic examination. The methanol extract of A. nilagirica leaves revealed no toxic effect on the hepatocytes on ultrastructural evaluation. This study demonstrates the antimicrobial, hepatoprotective and cardioprotective activities of ANE in broiler chickens infected with E. coli organism.

Abstract
Selection of appropriate bacterial strains is crucial for development of new probiotic preparations. The fundamental prerequisite for potential efficacy of a probiotic preparation for oral application is the selection of appropriate bacterial strains with good gastrointestinal colonisation abilities, antimicrobial activity, and tolerance of conditions in the gastrointestinal tract, resistance to different antimicrobial agents, survival during processing and storage. The strain should be genetically stable, it should have good growth properties, to maintain its high viability at processing and when in storage. Mostly, the properties of promising strains are tested in the first phase in vitro, and only the best ones undergo subsequent in vivo testing. in vitro tests are often performed by classical microbiological cultivation methods which are material and time consuming, and they are not able to distinguish between ‘viable but nonculturable’ and dead bacteria. Flow cytometry is usually used for counting, phenotyping or functional characterisation of immune cells. Nowadays, flow cytometry is increasingly used in microbiology for counting bacteria, determining their viability and metabolic activity, detecting specific strains or testing their adherence abilities. The utilisation of flow cytometry in combination with an appropriate fluorescent labelling represents an effective and rapid method for the selection of probiotic bacteria.
