“…Research in Vietnam documented the isolation of the same clone of E. faecalis in a patient's urine and poultry from the same household in which patient had close contact with poultry. In 23% of urinary tract infection cases, pulsed-field gel electrophoresis patterns identical or closely related to those found in poultry were detected (65). In another study carried out in Malaysia, one vancomycin-resistant E. faecium strain isolated from a chicken was found to be clonal to that of humans (23).…”

Enterococci rank as one of the leading causes of nosocomial infections, such as urinary tract infections, surgical wound infections, and endocarditis, in humans. These infections can be hard to treat because of the rising incidence of antibiotic resistance. Enterococci inhabiting nonhuman reservoirs appear to play a critical role in the acquisition and dissemination of antibiotic resistance determinants. The spread of antibiotic resistance has become a major concern in both human and veterinary medicine, especially in Southeast Asia, where many developing countries have poor legislation and regulations to control the supply and excessive use of antimicrobials. This review addresses the occurrence of antibiotic-resistant enterococci in Association of Southeast Asian Nations countries and proposes infection control measures that should be applied to limit the spread of multipledrug-resistant enterococci.

“…During our search through the available literature, we did not find any report in which the prevalence of Enterococci would be higher than that of Staphylococcus aureus, which predominates amongst the Gram-positive microflora [10,11]. There are several potential reasons behind such a high fraction of Enterococci, including severe dental caries [12], insufficient personal hygiene, co-existing urinary tract infection, or contact with poultry/poultry meat [13]. However, the selection of strains resulting from empirical antibiotic therapy, started prior to hospitalization and based mostly on β-lactams, to which Enterococci show natural resistance, seems the most rational explanation.…”

Background. Diabetic foot syndrome (DFS) represents one of the most frequent reasons for lower limb amputation in developed countries. In most cases, it is associated with bacterial infection, requiring optimal antibiotic therapy. Objectives. The aim of this study was to identify the most frequent pathogens responsible for infections associated with DFS, establish the optimal protocol of empirical therapy, and ascertain the clinical variables that may determine the choice of the appropriate antibacterial agent. Material and Methods. The analysis included hospital records of patients treated at the Department between 2008 and 2010. A total of 102 individuals were identified; their material was cultured and tested for antibiotic susceptibility. Results. A total of 199 bacterial strains were isolated. There was a predominance of Gram-positive bacteria, particularly Staphylococcus aureus, Staphylococcus coagulase-negative strains, and Enterococcus faecalis. Of note was the high percentage of E. faecalis infection (16.08%). One can speculate on the potential etiological factors in the case of some bacteria, e.g. patients infected with S. aureus were characterized by higher monocytosis and lymphocytosis as compared to other patients. Analysis of drug susceptibility revealed that ciprofloxacin has the highest (but still only 44%) efficacy of all agents tested as monotherapy, and a combination of piperacillin and tazobactam or amoxicillin and clavulanate with aminoglycosides is particularly beneficial. Conclusions. Staphylococcus spp. predominates amongst the etiological factors of DFS infection; however, the rate of E. faecalis infection is alarmingly high. Monotherapy enables effective treatment in a minority of cases; therefore, at least two-drug protocols should be implemented from the very beginning of the therapy (Adv Clin Exp Med 2014, 23, 1, 39-48).

“…In a study conducted in Vietnam, the bacterium ( Enterococcus [ E .] faecalis ) that was associated with urinary tract infection in humans was identical to the bacterial strain isolated from the flocks of a nearby poultry farm [30]. Conversely, some microorganisms that are non-pathogenic are capable of releasing by-products in the form of toxins (exotoxin, endotoxins and mycotoxins) that are harmful to both humans and animals [183241].…”

Microorganisms found in bioaerosols from animal confinement buildings not only foster the risk of spreading diseases among livestock buildings, but also pose health hazards to farm workers and nearby residents. This study identified the various microorganisms present in the air of swine, chicken, and cattle farms with different kinds of ventilation conditions in Korea. Microbial air samples were collected onto Petri dishes with bacterial or fungal growth media using a cascade impactor. Endotoxin levels in total dust were determined by the limulus amebocyte lysate kinetic QCL method. Prevalent Gram-positive bacteria were Staphylococcus (S.) lentus, S. chromogenes, Bacillus (B.) cereus, B. licheniformis, and Enterococcus faecalis, while the dominant fungi and Gram-negative bacteria were Candida albicans and Sphingomonas paucimobilis, respectively. Considering no significant relationship between the indoor dust endotoxin levels and the isolation of Gram-negative bacteria from the indoor air, monitoring the indoor airborne endotoxin level was found to be also critical for risk assessment on health for animals or workers. The present study confirms the importance of microbiological monitoring and control on animal husbandry indoor air to ensure animal and worker welfare.
