Case report: First report of and coinfection in an immunocompromised patient.

Legionnaires' disease (LD) is a serious type of pneumonia, typically contracted by susceptible people through the inhalation of aerosols contaminated with . In this report, the first case of coinfection with - is described. A possible source of the Lp infection may be the hotel in Paris (France) where the patient had stayed before developing the symptoms.

T Cell Peptide Prediction, Immune Response, and Host-Pathogen Relationship in Vaccinated and Recovered from Mild COVID-19 Subjects.

COVID-19 remains a significant threat, particularly to vulnerable populations. The emergence of new variants necessitates the development of treatments and vaccines that induce both humoral and cellular immunity. This study aimed to identify potentially immunogenic SARS-CoV-2 peptides and to explore the intricate host-pathogen interactions involving peripheral immune responses, memory profiles, and various demographic, clinical, and lifestyle factors.

Increasing Detection of Legionnaires' Disease in a Large Italian Hospital in the Period 2016-2023.

The pandemic marked the beginning of an era of dynamic and rapid changes in the diagnosis of respiratory infections. Herein we describe Legionnaires' disease trend in the years 2016-2023 in a large Italian hospital showing how improvements in diagnostic algorithms impact on its detection.

Nasopharyngeal carriage of Haemophilus influenzae among adults with co-morbidities.

Unlabelled: After the widespread use of Haemophilus influenzae type b (Hib) vaccine, H. influenzae invasive disease is now commonly due to non-encapsulated (NTHi), affecting mostly the youngest and the elderly. The objective of this study was to investigate H.

First evidence of blaNDM-1 and blaOXA-23 carbapenemase genes in human body lice infesting a second-hand T-shirt in a street market in Italy.

Background: The spread of carbapenems resistance is a public health concern. The main group of carbapenemases encoding the β-lactamases activity (bla genes) is the Metallo-β-lactamases (MBLs).

Methods: The presence of carbapenemase blaOXA-23-like, blaOXA-40-like, blaOXA-51-like, blaOXA-58-like, and blaNDM-1 genes was screened by real time PCR in 26 Pediculus humanus insects identified from second-hand clothes in a local market in Central Italy.

Laboratory management for SARS-CoV-2 detection: a user-friendly combination of the heat treatment approach and rt-Real-time PCR testing.

The RNA purification is the gold standard for the detection of SARS-CoV-2 in swab samples, but it is dependent on the availability of chemical reagents. In this study, we evaluated the heat treatment method without RNA extraction as a reliable option to nucleic acid purification.

Plasmodium vivax exflagellated microgametes in human peripheral blood: a potential diagnostic dilemma.

Both malaria and relapsing fever Borrelia are infectious diseases characterized by fever, headache, myalgia, hepatosplenomegaly and tendency to relapse. Exflagellation of microgametocyte in malarial parasites is seen only in the definitive host, i.e.

Primary Whipple disease of the Central Nervous System presenting with rhombencephalitis.

Primary Whipple disease of the Central Nervous System is a rare entity whose outcome might be fatal if not promptly diagnosed and treated. Few cases are reported in the literature with heterogeneous clinical and radiological presentations which often make the diagnosis extremely challenging. We report a case of primary Whipple disease of the Central Nervous System presenting with rhombencephalitis in a female patient in immunosuppressive treatment for rheumatoid arthritis.

Pneumococcal carriage among adults aged 50 years and older with co-morbidities attending medical practices in Rome, Italy.

Background: Data on Streptococcus pneumoniae carriage in adults with co-morbidities are limited. In this study we estimated the pneumococcal carriage among adults with co-morbidities and evaluated socio-demographic and clinical risk factors. The potential coverage of the current pneumococcal vaccines recommended for adults (PCV13 and PPV23) was also investigated.

Report of the human body louse (Pediculus humanus) from clothes sold in a market in central Italy.

Background: Pediculus humanus, the human body louse, is widespread where overcrowding and lack of hygiene are present, in areas of the world affected by poverty, war, famine and presence of refugees. It has recently been considered re-emerging among homeless populations in developed countries. In Italy, it was last reported in 1945.

Meningitis with cranial polyneuritis and cavernous sinus thrombosis by Borrelia crocidurae: First autochthonous case in Europe.

Borrelia crocidurae is endemic in West Africa, where it represents the leading cause of tick-borne relapsing fever (TBRF). TBRF typically presents with high fever and systemic symptoms, followed by recurrent episodes. Neurological complications may occur during febrile relapses.

HPV and Chlamydia trachomatis coinfection in women with Pap smear abnormality: baseline data of the HPV Pathogen ISS study.

Chlamydia trachomatis (Ct) and human papillomavirus (HPV) are the most common sexually transmitted pathogens. Whereas it is well known that infection with oncogenic HPV genotypes increases the risk of cervical cancer (CC), the implication of Ct in the pathogenesis of CC is still controversial. Hence, to investigate the possible implication of Ct infection alone, or with concomitant HPV infection, in the severity of cervical lesions, we conducted a study in 164 Caucasian HIV-negative women with abnormal Pap.

Draft Genome Sequence of Streptococcus suis Strain SsRC-1, a Human Isolate from a Fatal Case of Toxic Shock Syndrome.

is an economically important pathogen in the pig industry and is also an emerging zoonotic agent responsible for severe infections in humans. Here, we report the genome sequence of strain SsRC-1. Specifically, this strain was a serotype 2 and was isolated from a human fatal case of toxic shock syndrome (TSS) in Italy.

Tache Noire in a Patient with Acute Q Fever.

Objective: To describe a rare case of acute Q fever with tache noire.

Clinical Presentation And Intervention: A 51-year-old man experienced acute Q fever showing tache noire, generally considered a pathognomonic sign of Mediterranean spotted fever (MSF) and MSF-like illness, but not a clinical feature of Q fever. The patient was treated with doxycycline 100 mg every 12 h.

Respiratory diphtheria due to Corynebacterium ulcerans transmitted by a companion dog, Italy 2014.

A serious respiratory tract infection due to Corynebacterium ulcerans was observed in a 70-year-old woman. Clinical presentation included pseudomembranes in the upper respiratory tract and lung involvement. C.

Molecular characterization of Babesia and Theileria species in ticks collected in the outskirt of Monte Romano, Lazio Region, Central Italy.

Background: In 2012-2013, an investigation was carried out in the Viterbo province, Lazio region, on ticks and tick-borne Apicomplexan protozoa of the Babesia and Theileria genera. This followed the reporting of high density of ticks by soldiers operating in a military shooting range, and the signaling by owners and local veterinary authorities of several cases of babesiosis among cattle.

Methods: A total of 422 ticks were collected from 35 heads, whereas 96 ticks were collected by dragging.

A fatal case of streptococcal toxic shock syndrome caused by Streptococcus suis carrying tet (40) and tet (O/W/32/O), Italy.

We report the first human fatal case of streptococcal toxic shock syndrome (STSS) caused by Streptococcus suis serotype 2 carrying the tetracycline efflux tet (40) gene and the tetracycline ribosomal protection tet (O/W/32/O) gene. The patient was splenectomized. The case was characterized by multi-organ dysfunction and disseminated intravascular coagulopathy, in accordance with the clinical parameters of STSS.

Mediterranean spotted fever-like illness in Sardinia, Italy: a clinical and microbiological study.

Introduction: Rickettsioses represent a group of emerging infectious diseases in Europe. Climate changes and the anthropization of rural environment have favored vectors' biological cycle and geographic spread. In Sardinia, Mediterranean spotted fever (MSF) is endemic and represents an important public health problem.
