Prevalence of virulence factors in Staphylococcus intermedius isolates from dogs and pigeons.

BACKGROUND: Staphylococcus intermedius has been isolated from healthy dogs and pigeons as well as diseased dogs. Similar to Staphylococcus aureus, S. intermedius is known to carry many virulence factors but most of these factors remain to be studied. In this study, we examined 106 S. intermedius isolates (44 dog isolates and 62 pigeon isolates) for their hemolytic activity, biofilm formation, protease activity, and clumping factor and protein A production. RESULTS: Forty-three dog isolates (97.7%) and all pigeon isolates were hemolytic on sheep RBCs with a mean hemolytic titer of 336.7 and 47.32, respectively, whereas 43 dog isolates (97.7%) and 11 pigeon isolates (17.7%) exhibited a significant difference in their hemolytic activity on rabbit RBCs with a mean hemolytic titer of 11.04 and 3.76, respectively (p < 0.0005). The mean biofilm formation activity for dog isolates was 0.49, which was significantly higher than that (0.33) for pigeon isolates (p < 0.0005). Twenty-four dog isolates (54.5%) and 11 pigeon isolates (17.7%) were protease positive. Twenty-four dog isolates (54.5%) were clumping factor- and protein A- positive. CONCLUSION: S. intermedius strains carrying the virulence factors examined in this study were more prevalent in dogs than pigeons.

Acupuncture for general veterinary practice.

Since the International Society of Veterinary Acupuncture (IVAS) was founded in 1974, acupuncture (AP) has received greater acceptance by veterinary professionals throughout the world. This article introduces some important animal diseases that respond well to AP therapy. These include resuscitation of small animals, treatment of anoestrous gilts and sows, bovine reproductive disease, canine vertebral problems and equine backpain, etc. Conventional medicine considers these to be difficult cases to treat. Veterinarians have become more aware of the benefits of AP especially for those diseases, thanks to the efforts of experienced practitioners and scientists, and the many published reports on veterinary AP that have introduced some good indications for AP therapy in veterinary practice. Possible mechanisms behind the effectiveness of AP are discussed. This article aims to introduce veterinarians to good indications for AP to initiate their interest in the practice of AP. Although this is a rapidly expanding field, a long march must begin with one step. We wish this article to be the shoes for such a march. For more information on veterinary AP, contact IVAS , P.O. Box 1478, Longmont, CO.. 80502, USA (http://www.ivas.org), or your national veterinary acupuncture society (http://www.komvet.at/ ivadkom/vapsocs.htm).

[Ehrlichiosis in Switzerland--significance for veterinary medicine].

Ehrlichiosis is a rickettsial disease of animals and humans caused by various species of Ehrlichia. These obligate intracellular microorganisms infect granulocytes or monocytes of mammalian hosts and are transmitted mostly by ticks. The febrile disease is often undiagnosed and characterized by leukopenia, anemia and thrombocytopenia. The diagnosis of ehrlichiosis is based on clinical findings, tick infestation, direct or indirect detection of the agent, and serology. The role of native and imported ehrlichiae of animals in Switzerland is discussed.

Acupuncture for gastrointestinal disorders.

Acupuncture is best known for its application to various musculoskeletal pain-producing diseases. Acupuncture is, however, used for a large variety of internal medical diseases in humans and other animals. This chapter reviews some of the published literature on the use of acupuncture in gastrointestinal (GI) diseases, describes acupuncture points useful for a variety of GI diseases, briefly reviews how traditional Chinese medicine (TCM) treats GI disease, and gives some case examples of how acupuncture can be used in GI diseases.

Studies with canine sera that contain antibodies which recognize human immunodeficiency virus structural proteins.

In a serological survey, using the immunoblotting technique, we found that substantial numbers of dog sera from both normal and diseased dogs, including dogs with neoplasia, reacted with one or more human immunodeficiency virus (HIV) recombinant proteins. A total of 144 dog sera were tested, and 72 (50%) of them reacted with one or more HIV recombinant structural proteins. Ten dog sera were also tested for reactivity with simian immunodeficiency virus (SIV), feline immunodeficiency virus (FIV), and caprine arthritis encephalitis virus (CAEV). Six dog sera reacted with at least the major core protein of HIV, while one of the dog sera tested reacted with SIV core protein, and there were no reactions with the viral proteins of either FIV or CAEV. Cell extracts from canine peripheral blood lymphocytes cocultivated with human cells and an extract of human cells infected with HIV were immunoblotted against dog sera which previously tested positive or negative on HIV recombinant protein commercially available Western blot strips. Two lymphocyte lysates and the HIV-infected Hut cell lysate reacted with the Western blot strip-positive dog serum; however, no reactions were seen with the Western blot strip-negative dog serum.
