Opis:
Hepatitis E virus (HEV) genotype 3 is widespread in industrialized countries and widely recognized as a serious public health issue. HEV genotype 3 is excreted in both human and animal stools, having the potential to be introduced in aquatic environments through wastewater discharge. For this reason, waterborne transmission of the HEV genotype 3 is drawing increasing attention from the scientific community. Although studies in Portugal have shown that HEV circulates in both humans and swine, no study has yet focused on the presence of HEV in wastewater. Hence, a total of 60 water samples (influent and effluent) from 15 Wastewater Treatment Plants (WWTP) of different regions of Portugal were tested for the presence of HEV using a broad spectrum real-time RT-PCR with amplification within the ORF2 region of HEV genome. Positive samples were retested by nested RT-PCR with amplification within the ORF1 region, sequenced followed by phylogenetic analysis. HEV sequences were retrieved from two influent samples collected in December 2013 from WWTPs of North and Central of Portugal and classified in subgenotype 3i and 3f. This is the first study showing the presence of HEV in aquatic environments of Portugal.

Opis:
Introduction and objectives. The parasite Cryptosporidium spp. is an intracellular protozoa which has a broad range of hosts and zoonotic potential. It presents a serious health risk for agricultural workers and veterinarians. The aim of the study was to identify the species and subtypes of Cryptosporidium occurring in a veterinary student who came into contact with calves on a farm. Materials and method. The Ziehl-Neelsen staining technique was employed to confirm the presence of Cryptosporidium oocysts. ELISA test was applied to detect coproantigen in faecal specimens. Nested PCR was used to amplify a small ribosomal subunit (SSU rRNA) and sequencing of the GP60 gene served to identify the zoonotic subtypes. Results. The nested PCR allowed to confirm the C. parvum species; subsequently, the IIdA15G1 zoonotic subtype was identified. Conclusion. This is the first confirmed case in Slovakia of human cryptosporidiosis caused by the unique subtype IIdA15G1.

Opis:
The present study was undertaken to detect the presence of Chlamydophila psittaci antibodies in captive birds at the Wildlife Rescue Center, Ninoy Aquino Parks and Wildlife Nature Center, Quezon City, Philippines. Blood was collected from 36 birds of different species and the presence of antibodies against C. psittaci was detected using an ELISA-based test kit. 25% of the samples demonstrated antibodies against C. psittaci. The results of this study confi rmed the presence of C. psittaci antibodies among the captive birds examined.

Opis:
The presence of Anaplasma phagocytophilum, a tick-transmitted zoonotic pathogen, has been reported in Italy in humans and several animal species, including dogs, but data concerning its prevalence in the Italian canine population are lacking. The aim of this study was to determine the prevalence of A. phagocytophilum infection in hunting dogs which live in geographic areas of central Italy where the infection had been previously detected in wild animals. Sera from 215 hunting dogs were tested by indirect immunofluorescence antibody test (IFAT) to detect antibodies to A. phagocytophilum. Buffy coat samples from the same 215 animals were submitted to a polymerase chain reaction (PCR) assay specific for the A. phagocytophilum 16S rRNA gene. Thirty-two (14.8%) dogs proved to be seropositive with antibody titres from 1:40–1:2,560. The highest seroprevalence was observed in dogs 6–10-year-old. Two seropositive (0.9%) animals were also PCR positive. Sequencing of PCR products revealed gene sequences of A. phagocytophilum in both cases. These results confirm the presence of A. phagocytophilum in the Italian areas studied; thus, the zoonotic potential of this agent should be considered particularly for people, as hunters, at risk of exposure to tick bites.
