Aujeszky's Disease (Pseudorabies). An old threat in current pig industry? Part II. Epidemiology, Immunity, Prevention and the current situation in Greece
(2011)Aujeszky's disease (AD) (or pseudorabics) is an important viral disease of swine causing neurological signs in neonatal pigs, respiratory problems in fatteners and reproductive disorders in breeding stock. Swine is the ... -
Bacillus cereus: an important foodborne pathogen
(2010)B. cereus is a spore-forming bacterium, frequently found in the environment. Most of the strains can grow at a temperature range of 10 degrees - 42 degrees C. B. cereus grows under aerobic conditions, but anaerobic growth ... -
Bacterial flora and risk of infection of the ovine teat duct and mammary gland throughout lactation
(2007)We collected samples of teat duct material and mammary secretion from ewes in three farms (flock A, polyparous n = 7; flock B, polyparous n = 6, primiparous n = 4; flock C, polyparous n = 4): 14 samples immediately after ... -
Bacterial live vaccines with graded level of attenuation achieved by antibiotic resistance mutations: transduction experiments on the functional unit of resistance, attenuation and further accompanying markers
(1998)At least 10% of spontaneous chromosomal antibiotic resistant mutants of bacteria express a strain-dependent graded reduction of virulence; this correlates linearly with a prolonged generation time. Occasionally, these ... -
Bacteriological and epidemiological findings during examination of the uterine content of ewes with retention of fetal membranes
(2002)We included 92 pairs of ewes with or without retention of fetal membranes in a cohort study of 25 flocks in Southern Greece. We obtained two uterine content samples under aseptic conditions, by introducing a swab into the ... -
Basal cell carcinoma in a dog with chronic solar dermatitis
(2013)A seven-year-old, entire male, American Staffordshire bull terrier was diagnosed with chronic solar dermatitis and basal cell carcinoma, based on physical examination, cutaneous cytology and histopathology. Immunohistochemistry ... -
Bayesian estimation of sensitivity and specificity of serum ELISA and faecal culture for diagnosis of paratuberculosis in Greek dairy sheep and goats
(2006)Latent class models were used to estimate the sensitivity (Se) and the specificity (Sp) of a serum ELISA and a faecal culture (FC) method for the diagnosis of paratuberculosis separately, in sheep and goats. The estimates ... -
Bayesian estimation of variance partition coefficients adjusted for imperfect test sensitivity and specificity
(2009)The variance partition coefficient (VPC) measures the clustering of infection/disease among individuals with a specific covariate pattern. Covariate-pattern-specific VPCs provide insight to the groups of individuals that ... -
Bayesian mixture models for partially verified data: Age- and stage-specific discriminatory power of an antibody ELISA for paratuberculosis
(2013)Bayesian mixture models can be used to discriminate between the distributions of continuous test responses for different infection stages. These models are particularly useful in case of chronic infections with a long ... -
A Bayesian Weibull survival model for time to infection data measured with delay
(2010)Survival analysis methods can be used to identify factors associated with the time to induction of infection In the absence of a perfect test, detection of infection is generally delayed and depends on the duration of the ... -
Benign esophageal stricture in the dog and cat: A retrospective study of 20 cases
(2002)Twenty animals with benign esophageal strictures are presented. Most of the esophageal strictures were thought to be related to gastroesophageal reflux during ovariohysterectomy and were located at the distal portion of ... -
Biological, seasonal and environmental factors associated with Pulex irritans infestation of dairy goats in Greece
(2006)The objectives of the present study were to study the fauna of fleas infesting dairy goats in Greece, the spectrum of hosts each flea species infests, identify risk factors in the environment, and goat management practices ... -
Bone marrow mastocytosis in dogs with myelosuppressive monocytic ehrlichiosis (Ehrlichia canis): a retrospective study
(2006)Background: Bone marrow mastocytosis has been reported rarely in naturally occurring canine monocytic ehrlichiosis (CME). Objectives: The aims of the present study were to estimate the prevalence and magnitude of bone ... -
Canine acral lick dermatitis syndrome
(2012)Canine acral lick dermatitis is a complicated and challenging syndrome occurring in companion animal dermatology. Skin lesions are caused by intense and prolonged licking of a localized area, usually on the lower parts of ... -
Characteristics of non-cerebral coenurosis in tropical goats
(2015)The epidemiological, clinical, and biochemical profile of non-cerebral coenurosis in goats and the morphological characteristics of the responsible metacestodes (cysts) were examined in a cross-sectional survey of slaughtered ... -
Chronic canine ehrlichiosis (Ehrlichia canis): A retrospective study of 19 natural cases
(2004)Nineteen dogs from Greece with chronic ehrlichiosis were studied. The dogs exhibited bicytopenia or pancytopenia, bone marrow hypoplasia, seroreactivity to Ehrlichia canis ( E. canis) antigens, and had no history of drug ... -
Claw histopathology and parasitic load in natural cases of canine leishmaniosis associated with Leishmania infantum
(2010)Histological lesions and the presence of Leishmania spp. amastigotes in claw tissues were investigated in 40 dogs with leishmaniosis, with (16/40 - group A) or without (24/40 - group B) generalized onychogryphosis. Following ... -
Clinical and epidemiological findings during ram examination in 47 flocks in southern Greece
(2001)In a field investigation of 47 Rocks in south Greece, a clinical examination for fertility evaluation was done on 293 rams. In each ram, a general-health examination, examination of the genital organs and libido evaluation ...
