Analysis of canine parvovirus (CPV) isolates with a panel of monoclonal antibodies showed that after 1986, most viruses isolated from dogs in many parts of the United States differed antigenically from the viruses isolated prior to that date. The new antigenic type (designated CPV type 2b) has largely replaced the previous antigenic type (CPV type 2a) among(More)
Composites of chondrocytes and polymerised fibrin were supplemented with insulin-like growth factor-I (IGF-I) during the arthroscopic repair of full-thickness cartilage defects in a model of extensive loss of cartilage in horses. Repairs facilitated with IGF-I and chondrocyte-fibrin composites, or control defects treated with chondrocyte-fibrin composites(More)
A cross-sectional study was undertaken to determine the prevalence of Giardia sp. (G. duodenalis group), Cryptosporidium parvum and Cryptosporidium andersoni (C. muris) [corrected] in dairy cattle in three different age groups, and to evaluate the association of age and season with prevalence. One hundred and nine dairy farms, from a total of 212 farms, in(More)
A cross-sectional study was conducted to determine the prevalence of Cryptosporidium in wildlife in the New York City (NYC) Watershed in southeastern New York State. A total of 6227 fecal samples were collected and evaluated from 5892 mammals (38 species), 263 birds (14 species), 2 reptiles (2 species), 8 amphibians (4 species), and 62 fish (15 species).(More)
REASONS FOR PERFORMING STUDY Crib-biting is an equine stereotype that may result in diseases such as colic. Certain breeds and management factors have been associated. OBJECTIVES To determine: breed prevalence of crib-biting in US horses; the likelihood that one horse learns to crib-bite from another; and owner perceptions of causal factors. METHODS An(More)
Serial ultrasonographic examinations were performed on 8 Beagle bitches from 20 to 60 days pregnant to determine time of first detection, appearance, and sizes of selected features of pregnancy. Gestation was timed from the day of the preovulatory luteinizing hormone surge. Findings related to gestational age were consistent among bitches. Gestational ages(More)
Accurate prediction of parturition date is useful for clinical management of canine parturition. For nearly all normal canine pregnancies, parturition occurs 64-66 days from the LH peak, the timing of which cannot be differentiated from the initial sharp rise in serum progesterone (P4) concentrations. We sought to determine by retrospective analysis if(More)
Overuse tendon injuries are common among elite and recreational athletes. Tendon healing may be enhanced at the cellular level through the use of exogenous growth factors; however, little is known about the endogenous expression of growth factors in healing tendon. This study describes the temporal expression of insulin-like growth factor-I (IGF-I),(More)
Stem cells indigenous to the cancellous spaces of the bone bed in an acute injury provide an important source of pluripotent cells for cartilage repair. Insulin-like growth factor-I facilitates chondrogenesis of bone marrow-derived stem cells in long-term culture and may enhance chondrogenesis in healing cartilage lesions in vivo. This study examined the(More)
OBJECTIVE To identify intrinsic, management, nutritional, and environmental risk factors associated with equine motor neuron disease (EMND) and to determine whether epidemiologic evidence supports oxidative stress as a risk factor for developing EMND. DESIGN Case-control study. ANIMALS 87 horses with EMND and 259 control horses. PROCEDURE Information(More)
