Background: Twenty-five percent to 50% of acute gastroenteritis (AGE) cases remain etiologically undiagnosed. Our main aim was to determine the most appropriate list of enteric pathogens to be included in the daily diagnostics scheme of AGE, ensuring the lowest possible diagnostic gap.

Methods: Two hundred ninety seven children ≤6 years of age, admitted to hospital in Slovenia, October 2011 to October 2012, with AGE, and 88 ≤6 years old healthy children were included in the study.

Paediatric acute gastroenteritis is a global public health problem. Comprehensive laboratory investigation for viral, bacterial and parasitic agents is helpful for improving management of acute gastroenteritis in health care settings and for monitoring and controlling the spread of these infections. Our study aimed to investigate the role of various pathogens in infantile diarrhoea in Bulgaria outside the classical winter epidemics of rotavirus and norovirus.

Mammalian orthoreoviruses (MRVs) are known to cause mild enteric and respiratory infections in humans. They are widespread and infect a broad spectrum of mammals. We report here the first case of an MRV detected in a child with acute gastroenteritis, which showed the highest similarity to an MRV reported recently in European bats.

Pigeon circovirus (PiCV) was detected by real-time PCR in cloacal swabs, pharyngeal swabs, and serum samples taken from 74 feral pigeons (Columba livia var. domestica) that were caught at various locations in the city of Ljubljana, Slovenia. PiCV infections were detected in the majority of the tested birds.

Fourteen avian paramyxovirus type 1 (APMV-1; Newcastle disease) viruses isolated from dead free-living and domestic pigeons in Slovenia between 2000 and 2008 were analyzed by a molecular characterization of a part of the fusion protein gene, which included the region encoding the fusion protein cleavage site. Phylogenetic analysis indicated that the Slovene pigeon paramyxovirus type 1 (PPMV-1) viruses do not cluster together but instead are divided into two groups--4bi and 4bii--of sublineage 4b. Nine Slovenian strains were placed in group 4bii.

Newcastle disease virus (NDV), also designated avian paramyxovirus type 1 (APMV-1), is a serious pathogen of poultry, causing highly contagious Newcastle disease (ND), with high morbidity or mortality, depending on the strain. Accordingly, rapid and reliable detection of APMV-1 and differentiation between vaccine and virulent strains is of crucial importance for ND diagnosis and plays an important role in effective control of the disease. In this study, two real-time reverse transcription polymerase chain reaction (real-time RT-PCR) assays using minor groove-binding (MGB) probes were developed for broad range detection and simultaneous pathotyping of APMV-1.
