“…In human beings, S. aureus is considered an important primary pathogen causing skin bacterial diseases such as impedigo and staphylococcal scaledskin syndrome. In veterinary dermatology, S. aureus and S. hyicus have been implicated in dermatitis of chickens [20,28] and horses [5,24,27], and in exudative epidermitis of pigs [2], respectively. S. intermedius is one of the causative agents of canine bacterial skin disease such as otitis externa and pyoderma.…”

ABSTRACT. From April 1999 to December 2000, a survey was made on the distribution of Staphylococcus species on the skin of 7 kinds of animals and humans. Staphylococci were isolated from 12 (100%) of 12 pigs, 17 (89.5%) of 19 horses, 30 (100%) of 30 cows, 73 (90.1%) of 81 chickens, 10 (40%) of 25 dogs, 23 (76.7%) of 30 laboratory mice, 20 (52.6%) of 38 pigeons, and 80 (88.9%) of 90 human beings. The predominant staphylococci isolated from a variety of animal species were novobiocin-resistant species, S. xylosus and S. sciuri regardless of the animal host species. The novobiocin-resistant species including S. xylosus and S. sciuri were only occasionally isolated from human skin. The predominant staphylococci found on human skin were novobiocin-sensitive species, S. epidermidis (63.8%), followed by S. warneri (28.8%) and S. hominis (13.8%). The results suggest that the staphylococcal flora inhabiting animal skin are different from those of human skin in regard to the predominant species isolated. In this study, we used pulsed-field gel electrophoresis to examine the chromosomal polymorphisms of S. epidermidis isolated most frequently from human skin. Strains of S. epidermidis showed the greatest genomic diversity in their fragment patterns.KEY WORDS: animal and human skin, pulsed-field gel electrophoresis, Staphylococcus species.J. Vet. Med. Sci. 64(3): 245-250, 2002 Recently, taxonomic studies have shown that the genus Staphylococcus can be divided into at least 36 species and 17 subspecies, consisting of 6 coagulase-positive or coagulase-variable species and 31 coagulase-negative species.Staphylococci are widespread in nature and commonly found living on the skin, in skin glands, and on mucous membranes of humans and other mammals or birds. They are sometimes found in the mouth, blood, mammary glands, and intestinal, genitourinary, and upper respiratory tracts of these hosts.Knowledge of the distribution of the normal staphylococcal flora on the skin is an important factor in understanding the epidemiology of staphylococcal skin diseases in humans and animals. However, ecological studies on staphylococci inhabiting human [1, 12-14, 19, 21] and animal [6,12,16,26] skin have been reported infrequently in the literature. We [26] previously investigated Staphylococcus species on the skin of animals and humans during the period from 1987 to 1990, and found novobiocin-resistant staphylococci to be the predominant species in animals, whereas novobiocinsensitive staphylococci were abundantly present on human skin.In this report, we re-examined the distribution of Staphylococcus species on the skin of healthy animals and humans. We also compared the present results with those of our previous report [26] in terms of the isolation rate of staphylococci from the skin and the dominant species of staphylococci isolated.Among the coagulase-negative staphylococci species, S. epidermidis has been isolated most frequently from the anterior nares [1,9,13] or the skin [13,14] of healthy humans. Many reports have concerned the p...

“…Staphylococcus hyicus can be isolated from the skin of healthy horses but is more common in cases of infectious dermatoses such as pastern and coronary band dermatitis (Devriese et al, 1985;Shimozawa et al, 1997;Knottenbelt, 2009) and in subcutaneous abscesses, including those on the withers (Devriese et al, 1985). It is considered the fourth most important bacteria in equine skin lesions (Devriese et al, 1985).…”

Mammary disorders in mares are rare and usually only one animal per paddock is affected. In this report, two mares with 7 and 9 years old, were concomitantly diagnosis of chronic pyogranulomatous mastitis, associated with the Splendore-Hoeppli reaction, indicative of botryomycosis a rare, chronic suppurative disease with microabscess formation, characterized by in vivo formation of eosinophilic materials around microorganisms or biologically inert material. Various bacteria can cause botryomycosis in horses, and the most frequently isolated one is Staphylococcus sp., particularly S. aureus. This report confirms the role of Staphylococcus sp.; however, specifically S. hyicus and S. cohnii that prior to the current report, had not been associated with cases of botryomycosis.Keywords: equine, mastitis, mammary gland, botryomycosis RESUMO Enfermidades mamárias em éguas são raras e, normalmente, apenas um animal é afetado.

Increasingly infectious diseases of microbial pathogens (including bacteria and fungi) threaten human health a situation that has aroused public health concern around the world. Unfortunately, broad-spectrum antimicrobial agents of non-treatment resistance to date and molecular research on their antimicrobial mechanism are still scarce. Thus, the development of smart agents against microbial infection for surmounting the above dilemmas is an urgent task. In this contribution, we have tactfully designed a family of flexible AIEgens with various alkyl chain lengths and successfully optimized a cationic AIEgen TPA-S-C6-NMe 3 + based on the molecular relay strategy (MRS) for killing both bacteria and fungi in vitro with desired results under white light irradiation, superior to traditional commercial photosensitizers including methylene blue, chlorin e6, and protoporphyrin IX. The cationic AIEgens TPA-S-C6-NMe 3 + were bound to microbial pathogens via electrostatic and hydrophobic forces and exerted antimicrobial pathogens efficacy by virtue of the synergistic effect of alkyl chain length, reactive oxygen species (ROS) generation capability, and double-positive charges.Remarkably, AIEgen TPA-S-C6-NMe 3 + also exhibited a striking antimicrobial activity in vivo, and promoted the
