Human cytomegalovirus glycoprotein B genotypes in immunocompetent, immunocompromised, and congenitally infected Italian populations

Summary. Human cytomegalovirus (HCMV) strains, obtained from immunocompetent and immunocompromised Italian hosts, were typed with glycoprotein B (gB) gene restriction analysis. A predominant circulation of HCMV strains with gB type 2 and 3 was detected in both the immunocompetent host with a primary HCMV infection and the immunocompromised host with or without HCMV disease. No association between gB types and subjects with different risks of developing HCMV disease was found. All four gB genotypes were capable of causing congenital infection in Italian babies, with gB type 1 accounting for 50% of the strains examined in symptomatic infants and a remarkable incidence of gB type 4 viruses.

A novel VIM-type metallo-beta-lactamase (VIM-14) in a Pseudomonas aeruginosa clinical isolate from a neonatal intensive care unit.

A Pseudomonas aeruginosa highly resistant to carbapenems was isolated in a neonatal intensive care unit in Palermo, Italy. The strain was found to carry a novel VIM-type enzyme, classified as VIM-14. The novel enzyme differs from VIM-4 in a G31S mutation. VIM-14 was harboured in a class 1 integron with a new organization. The integron carried the genes aac7, blaVIM-14, blaOXA-20 and aac4 in that order.

Visiting Friends and Relatives (VFRs) travelers and imported malaria in the Palermo district (Sicily)

INTRODUCTION Although Italy has been malaria-free since 1970, the infection is commonly introduced into the country by travelers and immigrants from endemic areas. The term VFRs refers to immigrants from malaria-endemic countries who are regularly resident in a malaria-free area, and who travel to their countries of origin to visit friends and relatives (VFRs). This group is at special risk of malaria as they are unaware of having lost their transitory immunity to the disease. METHODS We conducted a retrospective study at the International Travelers Department of Palermo (Italy), examining records of malaria cases (67) reported over the period from 1998 to 2013. RESULTS VFRs represent the highest number of cases (77.6%), followed by workers (16.4%) and tourists (6.0%). All female patients and patients under the age of 18 were VFRs. Plasmodium falciparum was the most frequently-identified species. In all cases, chemoprophylaxis was not taken or was incomplete. CONCLUSIONS VFRs are at high risk of contracting malaria. This is probably related to an inequality in health care available to immigrants, as well as to ethnic and cultural conditions.
