Occurrence of the G3 Indian buffalo strain of echinococcus granulosus in cattle
During a survey carried out to define the occurrence of Echinococcus granulosus in cattle bred in the province of Rieti (Central Italy), molecular diagnostics (PCR amplification and sequencing of a partial region of the mitochondrial C01 gene) showed that 6/10 positive bovines harboured hydatid cysts (No.=16) genetically identical (95.8-100%) to the Indian buffalo genotype G3. As far the location of the 16 cysts, 11 of them were found in the lungs of three animals, whereas 5 cysts were in the liver of three parasitized hosts. The occurrence of genotype G3 in 60% of parasitized bovines living in an area never studied before provides more definite evidence about the existence of the strain in this region, and proves that cattle have to be considered a non-accidental host
Molecular characterization of rotavirus strains from children with diarrehea in Italy, 2007-2009.
The surveillance network RotaNet-Italia was
established in 2007 in order to investigate
the diversity of co-circulating rotavirus strains
in Italy, and to provide a baseline for future
assessment of possible effects of vaccine
implementation in selecting novel versus
common rotavirus strains. A total of 2,645
rotavirus strains from pediatric patients with
acute diarrhea were collected over three consecutive
seasons from September 2006 through
August 2009, and partially characterized by
standardized multiplex RT-PCR. Most of strains
(89.1%) belonged to genotypes G1\u2013G4, and G9,
associated with either P[8] or P[4], commonly
found in humans worldwide. However, in at
least 2.0% of cases, viruses exhibited either a G
or P type typical of animal viral strains, suggesting
gene reassortment events between
rotaviruses of different origin. Mixed infections
with two or more rotavirus strains were
observed frequently (7.6% of patients), and
depended on the frequencies of co-circulating
rotaviruses of one particular genotype. The
numbers and genotypes of likely natural reassortants
of common genotype rotaviruses were
found to be correlated with the observed numbers
and genotypes of mixed infections. Large
variation in the relative frequency of different
rotavirus genotypes was observed between different
seasons and/or areas of Italy, suggesting
independent evolution or differential introduction
of viral strains with respect to both time
and space
