Further evaluation of a novel polymeric antimicrobial for the control of porcine postweaning colibacillosis
نویسنده
چکیده
Materials and methods: In an experimental infection study, three groups of 12 weaner pigs received either Chemeq polymeric antimicrobial in the food, a therapeutic dosage of apramycin orally, or no treatment. Three days after weaning, the pigs were challenged orally with cultures of β-hemolytic Escherichia coli O8:K87:K88, then monitored daily and euthanized 11 days after weaning. In a field trial, 148 weaned pigs in a commercial swine herd were divided into five groups, receiving polymeric antimicrobial either in their water or food, apramycin in their water, a commercial E coli PWC bacterin, or no treatment. Postweaning performance was monitored.

Differential diagnoses for diarrhea in weaned pigs include salmonellosis, swine dysentery, porcine proliferative enteropathy (PPE) caused by Lawsonia intracellularis, rotavirus and coronavirus enteritis, postweaning colibacillosis, trichuriasis, coccidiosis,1 and porcine colonic spirochetosis (PCS) caused by Brachyspira pilosicoli.2 Postweaning diarrhea may be associated with multiple concurren...
متن کاملEncapsulation of irinotecan in polymeric nanoparticles: Characterization, release kinetic and cytotoxicity evaluation
Objective(s): Irinotecan is a potent anti-cancer drug from camptothecin group which inhibits topoisomerase I. Recently, biodegradable and biocompatible polymers such as poly lactide-co-glycolides (PLGA) have been considered for the preparation of nanoparticles (NPs). Materials and Methods: In this study, irinotecan loaded PLGA NPs were fabricated by an emulsification/solvent diffusion method to...

Background: The antibiotic resistance is considered as one of the biggest public health concerns in most countries. The aim of this study was to determine antibiotic resistance pattern of Escherichia coli isolated from chickens with colibacillosis in Yazd, Iran. Methods: A total of 200 carcasses of Ross chickens with colibacillosis were collected from farms located around Yazd, central Iran. A...
متن کاملHistomorphometric evaluation of intestinal cellular immune responses in pigs immunized with live oral F4ac+ non-enterotoxigenic E. coli vaccine against postweaning colibacillosis
Enterotoxigenic Escherichia coli (ETEC) infection is the most common type of porcine postweaning colibacillosis (PWC). Among fimbriae of porcine ETEC strains the best studied family of fimbriae are the members of F4 adhesins, existing in at least three variants: ab, ac, ad. Active immunization against porcine PWC is difficult due to: i) ETEC strains are only one of the essential predisposing fa...
متن کاملSwine enteric colibacillosis: diagnosis, therapy and antimicrobial resistance
Intestinal infection with enterotoxigenic Escherichia coli (ETEC) is an important disease in swine resulting in significant economic losses. Knowledge about the epidemiology, the diagnostic approach and methods of control are of fundamental importance to tackle the disease. The ETEC causing neonatal colibacillosis mostly carry the fimbriae F4 (k88), F5 (k99), F6 (987P) or F41, while the ETEC of...
