Langues : Anglais (eng) Catégories : Bactéries -- Identification Catabolisme Le catabolisme est l'ensemble des réactions de dégradations moléculaires de l'organisme considéré. Il est le contraire de l'anabolisme, ensemble des réactions de synthèse. Le catabolisme et l'anabolisme sont les deux composantes du métabolisme. Les réactions de catabolisme sont des oxydations (ou des déshydrogénations) et elles sont thermodynamiquement favorables, c'est-à-dire qu'elles sont exergoniques (cédant de l'énergie chimique, produisant de l'énergie). Les réactions du catabolisme des protides, glucides, lipides, acides nucléiques, etc., sont toutes intimement liées. Il s'agit d'un enchaînement de réactions chimiques.

Hence, the goal of this study was to examine members of the family Enterobacteriaceae on soaked sheepskins and cattle hides treated with antibacterial agent. In this study, bacterial species belonging to the family Enterobacteriaceae on five soaked sheepskins and ten cattle hides were identified using API® 20E test kits and the other biochemical tests. While Citrobacter freundii, Citrobacter koseri, Cronobacter sakazakii, Enterobacter amnigenus, Enterobacter cloacae, Kluyvera intermedia, Morganella morganii, Proteus mirabilis and Providencia rettgeri were isolated from the soaked sheepskins, Citrobacter koseri, Cronobacter sakazakii, Ewingella americana, Kluyvera intermedia, Morganella morganii, Providencia rettgeri, Serratia marcescens, Serratia plymuthica and Serratia rubidae were obtained from the soaked cattle hides. A fairly high percentage of soaked skin and hide samples contained Enterobacteriaceae members which have catabolic activities for deterioration of skins and hides. The presence of the members of Enterobacteriaceae on the soaked skin and hide samples was thought to be related to faecal contamination, the animal itself, environmental sources and inadequate preservation. As a conclusion, efficient antibacterial treatments should be applied in soaking process to kilt Enterobacteriaceae members which may adversely affect leather quality.

Examination of multidrug-resistant enterobacteriaceae isolated from salted cattle hides and sheep skins / Meral Birbir in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. CXI, N° 9 (09/2016)

Antibiotic resistance profiles of 27 cattle hide and 28 sheep skin isolates, obtained from five salted cattle hide and five skin samples originating in different countries such as Dubai, Turkey, Israel, Australia, Lebanon, U.S.A. and South Africa, were examined by disc diffussion susceptibility method using 24 different antimicrobial agents. Seventy percent of the salted hide isolates and sixty-eight percent of the salted sheep skin isolates exhibited resistance to three or more of 24 antimicrobial agents used. Less than 50% of the isolates was resistant to tobramycin (13%), cephalothin (16%), tetracycline (16%), amoxycillin-clavulanate (25%), ampicillin-sulbactam (29%), piperacillin-tazobactam (38%), cefoxitin (20%), ceftriaxone (45%), ceftazidime (33%), cefuroxime sodium (45%), trimethoprim-sulfamethoxazole (25%), ampicillin (45%), chloramphenicol (35%) and nalidixic acid (42%). Although 71% of isolates exhibited resistance to aztreonam, all isolates were susceptible to norfloxacin. Resistance to amikacin (5%), streptomycin (9%), kanamycin (9%), gentamicin (5%), imipenem (4%), meropenem (2%), ciprofloxacin (5%) and ofloxacin (2%) was not very common among the isolates. Our research results showed that multidrug-resistant Enterobacteriaceae were common on both salted cattle hide and sheep skin samples. Therefore, we suggest effective antibacterial applications during salt curing of hides and skins to eradicate these multidrug-resistant bacteria in the leather industry.

Identification and metabolic activities of bacterial species belonging to the enterobacteriaceae on salted cattle hides and sheep skins in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. CX, N° 6 (06/2015)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. CX, N° 6 (06/2015) . - p. 186-199 Titre : Identification and metabolic activities of bacterial species belonging to the enterobacteriaceae on salted cattle hides and sheep skins Type de document : texte imprimé Année de publication : 2015 Article en page(s) : p. 186-199 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Bactéries -- Identification Cuirs et peaux -- Analyse Cuirs et peaux de bovins Cuirs et peaux de moutons Entérobactériacées Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The detailed examination of the Enterobacteriaceae on salted hides and skins offers important information to assess faecal con-tamination of salted hides and skins, its roles in hide spoilage, and efficiency of hide preservation. Hence, salted cattle hide and skin samples were obtained from different countries and examined. Total counts of Gram-negative bacteria on hide and skin samples, respectively, were 104-106 and 105-106 CFU/g; of Enterobacteriaceae 104-105 and 105-106 CFU/g; of proteolytic Enter-obacteriaceae 103-105 and 105-106 CFU/g; of lipolytic Enterobacteriaceae 102-105 and 104-105 CFU/g; and of each species be-longing to Enterobacteriaceae 102-105 and 103-105 CFU/g. Moisture contents of the hide (between 17% - 29%) and skin samples (between 18% - 39%) were low, and salt saturations of most hide and skin samples were fairly high (100%), but these microor-ganisms were isolated from the samples in high numbers. Although 16 bacterial species belonging to genera of Cedecea, Enterobacter, Escherichia, Ewingella, Klebsiella, Proteus, Raoultella, Serratia and Yersinia were isolated from the hide sam-ples, 16 bacterial species belonging to genera of Citrobacter, Enterobacter, Escherichia, Klebsiella, Proteus, Raoultella, Serra-tia and Yersinia were isolated from the skin samples. These species were identified using API® 20E Test Kits. Although Cede-cea lapagei, Serratia rubidaea and Yersinia enterocolitica were the most prevalent microorganisms on the hide samples, Esche-richia coli, Serratia rubidaea and Serratia plymuthica were the most prevalent bacterial isolates on the skins. The most com-mon bacterial species isolated from both hides and skins was Serratia rubidaea. The presence of the members of Enterobacteri-aceae on the hides and skin samples in high numbers was evidence of faecal contamination and inadequate preservation. Ac-cording to biochemical test results, isolates exhibited catabolic activity to break down carbohydrate, lipid and protein which may adversely affect leather quality. Hide and skin samples contain different species of Enterobacteriaceae which may cause deterioration of hides and skins; therefore, effective antibacterial applications should be applied to hides and skins to eradicate these microorganisms and prevent substantial economical losses in leather industry.

Therefore the antibiotic resistance of Enterobacteriaceae isolated from soaked sheepskins and cattle hides was investigated. The antibiotic resistance of soaked skin isolates (Citrobacter freundii, Citrobacter koseri, Cronobacter sakazakii, Enterobacter amnigenus, Enterobacter cloacae, Morganella morganii, Proteus mirabilis, Providencia rettgeri) and soaked hide isolates (Citrobacter koseri, Cronobacter sakazakii, Morganella morganii, Providencia rettgeri, Serratia marcescens, Serratia plymuthica, Serratia rubidae) towards 24 different antibiotics were examined using the disc diffusion method. Among thirteen skin isolates, the percentages of resistance against antibiotics used were aztreonam 92%, ampicillin 69%, ceftriaxone 69%, streptomycin 62%, cephalothin 62%, amoxicillin/clavulanate 62%, ceftazidime 61%, nalidixic acid 54%, ciprofloxacin 54%, chloramphenicol 46%, piperacillin/tazobactam 46%, cefuroxime sodium 46%, tetracycline 31%, sulfamethoxazole-trimethoprim 15%, cefoxitin 15%, ampicillin/sulbactam 15%, kanamycin 15%, tobramycin 8%, meropenem 8% and imipenem 8%. Among ten hide isolates, the percentages of resistance against antibiotics were, ampicillin 80%, amoxicillin/clavulanate 80%, tetracycline 70%, cefuroxime sodium 70%, streptomycin 60%, aztreonam 50%, ceftriaxone 40%, chloramphenicol 30%, ceftazidime 20%, cephalothin 20%, nalidixic acid 30%, cefoxitin 20%, ampicillin/sulbactam 20%, piperacillinitazobactam 20%, ciprofloxacin 20% and kanamycin 10%. While all skin isolates were susceptible to amikacin, gentamicin, ofloxacin, and norfloxacin, all hide isolates were susceptible to amikacin, gentamicin, tobramycin, meropenem, sulfamethoxazole-trimethoprim, norfloxacin pnd ofloxacin. As a conclusion, the species of the family Enterobacteriaceae which were resistant to the antibiotics used in human and veterinary medicine were detected on the soaked skins and hides in the leather industry.
