Intestinal contents of suckling (n = 45) and newly weaned (n = 45) piglets, suffering from diarrhea in the province of Villa Clara in Cuba, were tested for viral, bacterial, and parasitic enteropathogens from May to June 2008. At least one enteropathogen was identified in 53.3 % of piglets and enterotoxigenic Escherichia coli (ETEC; 25.6 %) was the major pathogen; mostly STa(+)/STb(+) or F4(+)/STa(+)/STb(+) ETEC were isolated. The overall occurrence of the rest of pathogens was 10 % for transmissible gastroenteritis virus (TGEV) and Cryptosporidium parvum, 6.7 % for rotavirus A and Isospora suis, 5.6 % for α-toxigenic Clostridium perfringens, 3.3 % for verotoxigenic E. coli (VTEC), and 2.2 % for Salmonella enterica subspecies enterica serovar Newport. TGEV and α-toxigenic C. perfringens were only identified in suckling piglets, while Salmonella Newport and VTEC were only detected in weaned pigs. Porcine epidemic diarrhea virus (PEDV), β-toxigenic C. perfringens, Eimeria spp., and helminths were not identified. Eight kinds of mixed infections were detected in 25 % of enteropathogen positive piglets. ETEC was present in 10 of 12 mixed infections, and TGEV infections were never combined. This survey demonstrates that several enteropathogens are circulating in piggeries located in the province of Villa Clara in Cuba, and that is necessary to improve surveillance, prevention, and control of enteric infections in order to increase production efficiency.
2008年5月至6月,对古巴比那尔德里奥省患有腹泻的哺乳仔猪(n = 45)和刚断奶仔猪(n = 45)的肠道内容物进行了病毒、细菌和寄生虫肠道病原体检测。在53.3%的仔猪中至少鉴定出一种肠道病原体,产肠毒素大肠杆菌(ETEC;25.6%)是主要病原体;分离出的大多是STa(+)/STb(+)或F4(+)/STa(+)/STb(+) ETEC。其余病原体的总体检出率为:传染性胃肠炎病毒(TGEV)和微小隐孢子虫为10%,A组轮状病毒和猪等孢球虫为6.7%,产α毒素的产气荚膜梭菌为5.6%,产志贺毒素大肠杆菌(VTEC)为3.3%,肠炎沙门氏菌亚种肠炎血清型纽波特为2.2%。TGEV和产α毒素的产气荚膜梭菌仅在哺乳仔猪中鉴定出,而纽波特沙门氏菌和VTEC仅在断奶仔猪中检测到。未鉴定出猪流行性腹泻病毒(PEDV)、产β毒素的产气荚膜梭菌、艾美耳属寄生虫和蠕虫。在25%的肠道病原体阳性仔猪中检测到8种混合感染。12种混合感染中有10种存在ETEC,且从未发现TGEV感染合并其他感染。本次调查表明,古巴比那尔德里奥省的养猪场中有几种肠道病原体在传播,为提高生产效率,有必要加强对肠道感染的监测、预防和控制。
