Sciences VétérinairesTags : Escherichia coli Souches d’E. coli Aviaires Souches d’E. coli Humaines Antibiorésistance Prévention "ميكروب الآي كولاي القولونية سلالات القولونية من الطيور سلالات القولونية من الإنسان مقاومة المضادات الحيوية الوقاية Index. décimale : 636 Sciences Vétérinaires Résumé : Escherichia coli infections or colibacillosis continue to be always a major cause of economic losses for
poultry farms. Apart from the pathogens of Escherichia coli that are responsible for it, it is important
to do shed light on the strains Escherichia coli saprophytes antibiotic-resistant wich are responsible
for therapeutic failures and wich are representing the main source of the spread of this antibiotic
resistance, through resistant genes, thus ensuring their transmission to other saprophytic agents and
pathogenic in humans as well as in poultry (in particular) and animals (in general).
In this study, we show the emergence of a multiresistance through the resistance profile of two
collections of E. coli poultry Experimental (ELEX1 and ELEX2) to the 6 Quinolones tested
(Flumequine (UB), Pefloxacin (PEF), Norfloxacin (NOR), Enrofloxacin (EN), Ciprofloxacin (CIP),
and experimental avian influenza vaccines (ELEX1 and ELEX2), as well as a multiresistance through
the resistance profile of two collections of E. coli Poultry and Humain to the 40 antibiotics tested
(Ampicillin (AMX), Piperacillin (PRL), Ticarcillin (TC), Amoxicillin / Clavulanic Acid (AMC),
Cefalexin (CN30), Cefazoline (CZ), Cefalotine (CF) Cefepaxime (CTX), Cefotaxime (CRT),
Cefitaxone (FOX), Ceftazidime (CAZ), Cefixime (CFM), Aztreonam ), Gentamycin (CN10),
Tobramycin (TOB), Amikacin (AK), Kanamycin (K), Netilmicin (NET), Streptomycin (S),
Tetracycline (TE), Doxyciline (DXT), Nalidixic Acid NA), Flumequine (UB), Pefloxacin (PEF),
Norfloxacin (NOR), Ofloxacin (OFX), Ciprofloxacin (CIP), Sulfonamides (SSS), Trimethoprim
(TMP), Trimethoprim / Sulfamethoxazole Chloramphenicol (C), Fosfomycin (FF), Nitofurantoines
(F)).
Out of a total of 2635 samples, of which 264 were taken from the two experimental poultry farms (108
for ELEX1 and 156 for ELEX2), 600 collected from the 12 broiler farms (from the 06 communes of
the wilaya of Constantine) and 1771 collected from patients of CHU of Constantine (hospital and
ambulatory), we obtained 291 of antibiotic-resistant E. Coli strains, including 46 antibiotic-resistant E.
Coli strains to the 06 quinolones (for the two collections of E. coli Experimental), 120/209 of E. coli
strains (for E. coli aviary strains) and 125 of E. coli strains (for E. coli Human strains) to the 40
antibiotics tested.
From the different resistance profiles obtained, the emergence of several resistance profiles follow a
selection pressure for antibiotics by misuse of the latter in veterinary medicine and in human medicine
(upstream) but also to the dissemination of resistance genes by failure to respect hygienic measures
(downstream) and which remain the business of all.Therefore antibiotic resistance monitoring is
required at all levels and at all times by the systematic application of ""broad-spectrum antibiogram »
on commensal and pathogenic bacterial populations.

Sciences VétérinairesTags : Escherichia coli Antibiorésistance Traitement oral Fluméquine uinolones Flore fécale Poulet de chair Index. décimale : 636 Sciences Vétérinaires Résumé : Two moleculs of quinolones (flumequine and enrofloxacin) were administrated by oral form according to
two modes of watering (on a 3 hours and 24 hours period of time) in treatment of experimental poultry colibacillosis
after inoculation of the most pathogenic strain of Escherichia coli (O78:K80) at broiler chickens.
The emergence of antibiotic resistance, just after oral administration on a 24 hours period of watering of
flumequine and Enrofloxacine, allowed be setting obviously the influence of oral treatment on this quinolones
resistance.
In addition of administration mode, an other elements, like antibiotic’s moleculs, bacterial strain, and
animal species, seem to be associated to this antibiotic resistance and let suppose their intervention later, in so far as
factors influencing on level’s resistance.
The emergence of quinolone’s resistance on all bacterial species, were recognized after introduction of
these molecules in therapy and were reported by many studies carried on this family of antibiotic, and so, an
antibiotic resistance surveillance are imperative.

In order to determine the optimal parameters for the plasma jet generation by an AC or pulsed excitation and to ensure maximum exploitation of this latter, we carried out a series of electrical and optical measurements. The effects of the variation of the nature of the excitation signal, the applied voltage amplitude and frequency on the geometry of the jet and the reactive species created in air by this plasma jet were studied.
First, we used our plasma jet created in using argon at atmospheric pressure for the inactivation of Escherichia coli bacterium spread on a solid surface. We have shown that the inactivation capacity of microorganisms by this plasma jet is directly related to the distance jet source – treated surface as well as to the duration of the treatment. The inactivation rate is more significant as the jet source – sample distance is minimal and the treatment duration is high.
Secondly, we treated deionized water contaminated with E-coli bacteria using our plasma jet. We have shown that this treatment allows the creation of ozone, hydrogen peroxide and nitrite. However, the concentrations of these species generated by the plasma jet remain relatively low in order to obtain an effective inactivation of Escherichia coli present in the same amount of deionized water.
These investigations have shown that the composition and the dimensions of the created plasma jet can be controlled by means the nature of the excitation signal, its amplitude and / or its frequency. They have also shown that our plasma jet is more effective for the treatment of solid surfaces than for the treatment of aqueous media.
