ABSTRACT
Turnip mosaic virus (TuMV) was found infecting cultivated brassicas and wild and cultivated ornamental Brassicaceae plants in different regions of Spain. Five new TuMV isolates, originating from different host plant species (Brassica cretica, Brassica juncea, Brassica napus, Eruca vesicaria subsp. sativa and Sisymbrium orientale), have been identified. The nucleotide sequences of the coat protein (CP) genes of the five isolates were determined. Phylogenetic analysis of the CP sequences showed that the five isolates grouped into two different clusters. The three isolates from the central region of Spain clustered with a previously reported Pisum sativum isolate from southeastern Spain, whereas the other two isolates from the eastern region clustered with two Italian and two Greek isolates. Both clusters were genetically distinct and belonged to the multi-lineage group OBR. The OBR group contains mainly TuMV isolates from hosts other than Brassica spp. and Raphanus sativus and mostly originating from Mediterranean countries. These new sequences provide further phylogenetic resolution of the OBR group. Although new TuMV isolates have been found in Spain, they were not associated with any serious disease outbreaks.

The prevalence of HCV infection in Spanish prisons is very high (38.5%). The characteristics of the infected patients, particularly the high rate of HIV coinfection, makes it very likely that the morbidity and mortality produced by serious liver disease secondary to this infection will increase considerably in the coming years. A group of Spanish experts with experience in patients who are inmates has been invited to establish a series of recommendations for the diagnosis and treatment of chronic hepatitis C infection in Spanish prisons.
ABSTRACT
La prevalencia de la infección por el virus de la hepatitis C (VHC) en las prisiones españolas es muy elevada (38,5%). Las características de los pacientes infectados, especialmente la elevada coinfección con el virus de la inmunodeficiencia humana (VIH), hacen probable que la morbilidad y mortalidad producida por enfermedad hepática grave secundaria a esta infección aumente de forma considerable en los próximos años. Un grupo de expertos multidisciplinar con experiencia con pacientes internados en prisiones españolas ha sido invitado a establecer una serie de recomendaciones para el diagnóstico y tratamiento de la hepatitis C en las prisiones españolas

We cloned the Penicillium chrysogenum trpC gene from a genomic library by complementation of an Escherichia coli trpC mutant lacking phosphoribosylanthranilate isomerase activity. The gene encodes a 2.7 kb poly(A)+ RNA. We localized the gene by sequence analysis in a 2.9 kb DNA insert found in the smallest plasmid selected from the library. Sequence data strongly suggest that the organization of the gene is similar to that described in other Ascomycetes. We found that a DNA fragment which codes only for the carboxy-terminal portion of the polypeptide is sufficient for complementation of the E. coli trpC9830 mutation.
