Abstract

Objectives

To characterize the antimicrobial susceptibility, molecular epidemiology and carbapenem resistance mechanisms in Pseudomonas aeruginosa isolates recovered from respiratory tract samples from patients with ventilator-associated pneumonia enrolled in the MagicBullet clinical trial.

Methods

Isolates were collected from 53 patients from 12 hospitals in Spain, Italy and Greece. Susceptibility was determined using broth microdilution and Etest. MALDI-TOF MS was used to detect carbapenemase activity and carbapenemases were identified by PCR and sequencing. Molecular epidemiology was investigated using PFGE and MLST.

Results

Of the 53 isolates, 2 (3.8%) were considered pandrug resistant (PDR), 19 (35.8%) were XDR and 16 (30.2%) were MDR. Most (88.9%) of the isolates from Greece were MDR, XDR or PDR, whereas fewer of the isolates from Spain (33.3%) and Italy (43.5%) showed antibiotic resistance. Three Greek isolates were resistant to colistin. Overall, the rates of resistance of P. aeruginosa isolates to imipenem, ciprofloxacin, ceftolozane/tazobactam and ceftazidime/avibactam were 64.1%, 54.7%, 22.6% and 24.5%, respectively. All isolates resistant to ceftolozane/tazobactam and ceftazidime/avibactam (Greece, n = 10; and Italy, n = 2) carried blaVIM-2. Spanish isolates were susceptible to the new drug combinations. Forty-eight restriction patterns and 27 STs were documented. Sixty percent of isolates belonged to six STs, including the high-risk clones ST-111, ST-175 and ST-235.

Conclusions

MDR/XDR isolates were highly prevalent, particularly in Greece. The most effective antibiotic against P. aeruginosa was colistin, followed by ceftolozane/tazobactam and ceftazidime/avibactam. blaVIM-2 is associated with resistance to ceftolozane/tazobactam and ceftazidime/avibactam, and related to highly resistant phenotypes. ST-111 was the most frequent and disseminated clone and the clonal diversity was lower in XDR and PDR strains.

Abstract

In Italy, B and C are the predominant serogroups among meningococci causing invasive diseases. Nevertheless, in the period from 2013 to 2016, an increase in serogroup W Neisseria meningitidis (MenW) was observed. This study intends to define the main characteristics of 63 MenW isolates responsible of invasive meningococcal disease (IMD) in Italy from 2000 to 2016. We performed whole genome sequencing on bacterial isolates or single gene sequencing on culture-negative samples to evaluate molecular heterogeneity. Our main finding was the cocirculation of the Hajj and the South American sublineages belonging to MenW/clonal complex (cc)11, which gradually surpassed the MenW/cc22 in Italy. All MenW/cc11 isolates were fully susceptible to cefotaxime, ceftriaxone, ciprofloxacin, penicillin G and rifampicin. We identified the full-length NadA protein variant 2/3, present in all the MenW/cc11. We also identified the fHbp variant 1, which we found exclusively in the MenW/cc11/Hajj sublineage. Concern about the epidemic potential of MenW/cc11 has increased worldwide since the year 2000. Continued surveillance, supported by genomic characterisation, allows high-resolution tracking of pathogen dissemination and the detection of epidemic-associated strains.

Abstract

BACKGROUND:

Guillain-Barré syndrome (GBS) is an acute/subacute autoimmune inflammatory polyradiculoneuropathy. Previous epidemiological studies carried out in the province of Ferrara, Italy, from 1981 to 2002 indicated that GBS incidence had tendency of increase in the period considered.

OBJECTIVES:

We aimed at updating the epidemiology of GBS in the years 2003-2017 and carrying on the work started in the 1980s.

METHODS:

We conducted an incidence study, by adopting a complete enumeration approach. Cases were identified from administrative, medical records, and database of the Ferrara Hospital and other provincial structures of the study area. Case ascertainment and definition are analogous to those adopted in previous surveys.

RESULTS:

In the period 1 January 2003 to 31 December 2017, 73 patients living in the province of Ferrara (mean population 353,142) were found to be new cases of GBS fulfilling the NINCDS criteria. Male/female ratio 1.15. The mean incidence rate was 1.38 per 100,000 (95% CI 1.08-1.74), 1.54 per 100,000 for men and 1.23 per 100,000 for women, a nonsignificant difference. During the period considered, the rates had slow increase or mild decrease, without nonsignificant difference. The highest rates were observed for the age groups 70-79 years for both sexes. A half of patients reported infectious events in the weeks before the onset of symptoms.

CONCLUSION:

In line with many epidemiological data, in the whole period 2003-2017, we observed a trend towards increase or decrease in incidence and periods of relative stability. Similar temporal heterogeneity with the comparison to our previous works was found.

Abstract

Blood donation screening for West Nile virus (WNV) was mandatory in the Lazio region in 2017 and 2018 (June-November) according to the national surveillance plan. In these years, all five donations reactive in WNV nucleic acid amplification tests harboured instead Usutu virus (USUV). Clade ‘Europe 2’ was identified in four blood donations and a 2018 mosquito pool. The cocirculation of WNV and USUV in Lazio warrants increased laboratory support and awareness of possible virus misidentification.

Abstract

We report biomolecular evidence of dolphin morbillivirus in 4 wild Eurasian otters (Lutra lutra) from southern Italy; 2 animals showed simultaneous immunohistochemical reactivity against morbilliviral antigen. These cases add further concern and support to the progressively expanding host range of dolphin morbillivirus in the western Mediterranean Sea.

Abstract

Between October 2016 and December 2017, several European Countries had been involved in a massive Highly Pathogenic Avian Influenza (HPAI) epidemic sustained by H5N8 subtype virus. Starting on December 2016, also Italy was affected by H5N8 HPAI virus, with cases occurring in two epidemic waves: the first between December 2016 and May 2017, and the second in July-December 2017. Eighty-three outbreaks were recorded in poultry, 67 of which (80.72%) occurring in the second wave. A total of 14 cases were reported in wild birds. Epidemiological information and genetic analyses were conjointly used to get insight on the spread dynamics. Analyses indicated multiple introductions from wild birds to the poultry sector in the first epidemic wave, and noteworthy lateral spread from October 2017 in a limited geographical area with high poultry densities. Turkeys, layers and backyards were the mainly affected types of poultry production. Two genetic sub-groups were detected in the second wave in non-overlapping geographical areas, leading to speculate on the involvement of different wild bird populations. The integration of epidemiological data and genetic analyses allowed to unravel the transmission dynamics of H5N8 virus in Italy, and could be exploited to timely support in implementing tailored control measures.

Abstract

This paper proposes a new estimate for the number of victims of Spanish flu in Italy and highlights some aspects of mortality closely linked to the First World War. The sources used are official death statistics and the Albo d’oro, a roll of honor of the Italians fallen in the First World War. The new estimate of deaths from the flu is 410,000 for 1918, which should be raised to 466,000 when the numbers are taken up to 1920. Deaths from Spanish flu among the military were about 70,000. The time sequence of deaths recognizes two distinct peaks, one in October and one in November 1918. Between these two peaks, the lowest number of deaths falls in the week of the armistice between Italy and Austria-Hungary (signed 4 November 1918). This suggests links between Spanish flu and WWI that cannot be merely explained in terms of movement of people and contagion.
