Aortoenteric fistulas are a very unlikely cause of digestive bleeding. We present the case of a fifty six year old patient with a primary aortoduodenal fistula who consulted because of melena and a pulsating abdominal mass. He underwent three digestive endoscopies without arriving at any diagnosis. A computed axial tomography and an angiography showed an(More)
The objective was to investigate the changes occurring in the activities of the enzymes lactate dehydrogenase (LDH), alkaline phosphatase (ALP) and aspartate aminotransferase (AST) in sheep and goat milk as a result of subclinical intramammary infections (IMI) and to evaluate the use of these enzymes for the diagnosis of subclinical IMI in dairy sheep and(More)
Vaccination of young animals (3-6-month-old sheep and goats) with Rev-1 vaccine for 15 years in Greece, importantly decreased the abortions in sheep and goats as well as the incidence of brucellosis in humans. After the stop of vaccination in 1994, all over Greece, the prevalence of brucellosis in animals and the incidence in humans quickly increased. It(More)
Fluorescence polarization assay (FPA) is a new test for the serological diagnosis of Brucella spp. infection in animals. The FPA is validated for the diagnosis of B. melitensis infection in sheep. For this purpose, 166 sera originated from natural infected sheep (verified by culture) and 851 sera originated from healthy animals (reared in areas where B.(More)
A competitive enzyme-linked immunosorbent assay (cELISA) was validated for the serodiagnosis of Brucella melitensis infection in small ruminants using 2108 positive and 2154 negative reference sera from sheep and goats. The optimum cut-off values, offering the highest diagnostic sensitivity (DSn) and diagnostic specificity (DSp), determined by receiver(More)
The confirmed cases of human brucellosis in the area of Larissa in Central Greece from 2003 to 2005 were analyzed to assess the features of the affected population and to determine the factors influencing the acquisition of infection. Data of patients infected by Brucella spp. concerning age, gender, occupation, date of diagnosis and the observed symptoms(More)
Echinococcosis notification rate in Greece, based on the most recent data, is below 0.25 per 100,000 population. To further investigate the epidemiology of echinococcosis in Greece a study was designed to determine the seroprevalence of Echinococcus granulosus antibodies in the population of Thessaly, Central Greece. Five hundred and forty two left over(More)
Fluorescence polarization assay (FPA) is a relatively new test for the serological diagnosis of Brucella spp. infection in animals. FPA, carried out in 96-well microplate format, was validated here for diagnosing B. melitensis infection in sheep and goats. This study included sera from 1933 sheep and goats, from animals reared in naturally infected flocks(More)
The main objective of this study was to investigate whether cholelithiasis in sheep is related to parasitism or other commonly observed disorders such as liver abscesses. Additionally, the features of the observed biliary calculi are described. The livers of 254 randomly selected clinically healthy adult dairy sheep were used. All visible concretions in the(More)
The serological response of young and adult sheep vaccinated conjunctivally with Rev-1 vaccine was assessed by fluorescence polarization assay (FPA), Rose Bengal test (RBT), complement fixation test (CFT), modified Rose Bengal test (m-RBT), indirect ELISA (i-ELISA) and competitive ELISA (c-ELISA), at different post vaccination intervals. One hundred and(More)
