The increased resistance of this pathogen is leading to limited therapeutic options. To investigate the epidemiology, virulence, and antibiotic resistance profile of K. pneumoniae in urinary tract infections, we conducted a multicenter retrospective study for a total of 81 isolates (50 CA-UTI and 31 HA-UTI) in Portugal. The detection and characterization of resistance and virulence determinants were performed by molecular methods (PCR, PCR-based replicon typing, and multilocus sequence typing (MLST)). Out of 50 CA-UTI isolates, six (12.0%) carried β-lactamase enzymes, namely blaTEM-156 (n = 2), blaTEM-24 (n = 1), blaSHV-11 (n = 1), blaSHV-33 (n = 1), and blaCTX-M-15 (n = 1). All HA-UTI were extended-spectrum β-lactamase (ESBL) producers and had a multidrug resistant profile as compared to the CA-UTI isolates, which were mainly resistant to ciprofloxacin, levofloxacin, tigecycline, and fosfomycin. In conclusion, in contrast to community-acquired isolates, there is an overlap between virulence and multidrug resistance for hospital-acquired UTI K. pneumoniae pathogens. The study is the first to report different virulence characteristics for hospital and community K. pneumoniae pathogens, despite the production of β-lactamase and even with the presence of CTX-M-15 ESBL, a successful international ST15 clone, which were identified in both settings. This highlights that a focus on genomic surveillance should remain a priority in the hospital environment.This research was funded by the Research Institute for Medicines (iMed.ULisboa), Faculty of Pharmacy, Universidade de Lisboa (ULisboa).info:eu-repo/semantics/publishedVersio

Key comparison CCQM-K73 amount content of H+ in hydrochloric acid (0.1 mol·kg-1)
This key comparison (KC), CCQM-K73, was performed to demonstrate the capability of the participating National Metrology Institutes (NMIs) to measure the amount content of H+ , νH + , in an HCl solution with a nominal νH + of 0.1 mol·kg-1 . A parallel Pilot Study, CCQM-P19.2, was performed for NMIs that did not desire to participate in the KC. The comparison was a joint activity of the Electrochemical Working Group (EAWG) and Inorganic Analysis Working Group (IAWG) of the CCQM and was coordinated by NIST (USA) and CENAM (México). The method of determination of νH + was left to the individual participant. All participants used either coulometry or titrimetry with potentiometric determination of the endpoint. The agreement of the results was not commensurate with the claimed uncertainties of the subset of participants that claimed small uncertainties for this determination. A workshop on technical issues relating to the CCQM-K73 measurements was conducted at the joint IAWGEAWG meeting at the Bureau International des Poids et Mesures (BIPM), Paris (Sèvres) in April 2010. Several possible sources of bias were investigated, but none could explain the observed dispersion among the participants’ results. In the absence of a specific cause for the dispersion, the IAWG and EAWG decided to assign a Key Comparison Reference Value, KCRV, and standard uncertainty of the KCRV, uKCRV, based on the DerSimonian-Laird statistical estimator. The uKCRV is dominated by the between-laboratory scatter of results in CCQM-K73. The uncertainty estimates from the participants with the lowest reported uncertainties remain unsupported by this KC.Fil: Pratt, Kenneth W.

First Description of Colistin and Tigecycline-Resistant <i>Acinetobacter baumannii</i> Producing KPC-3 Carbapenemase in Portugal
Herein, we describe a case report of carbapenem-resistant Acinetobacter baumannii and Klebsiella pneumoniae isolates that were identified from the same patient at a Tertiary University Hospital Centre in Portugal. Antimicrobial susceptibility and the molecular characterization of resistance and virulence determinants were performed. PCR screening identified the presence of the resistance genes blaKPC-3, blaTEM-1 and blaSHV-1 in both isolates. The KPC-3 K. pneumoniae isolate belonged to the ST-14 high risk clone and accumulated an uncommon resistance and virulence profile additional to a horizontal dissemination capacity. In conclusion, the molecular screening led to the first identification of the A. baumannii KPC-3 producer in Portugal with a full antimicrobial resistance profile including tigecycline and colistin
Isolation of Rasamsonia argillacea species complex in a Cystic Fibrosis Adult Patient - First Case in Portugal
Abstract publicado em: J Fungi. 2021;7(11):263-64 (P176). https://doi.org/10.3390/jof7110916Objectives: Cystic fibrosis (CF) is the most common monogenetic autosomal reces sive disease in the human population. An important fungal biota has been described in
respiratory secretions of patients suffering from CF being Aspergillus fumigatus and Candida albicans the most common fungi found. We report the isolation, for the first time in
Portugal, of the emerging fungal pathogen Rasamsonia argillacea species complex, from a
respiratory sample of an adult patient with CF.
Material & Methods: A 51-year-old male patient with heterozygous CF due to muatations ΔF508/P205S, is being followed in Cystic Fibrosis Reference Center for about 10
years. In the last years, he has been consistently colonized with Methicilin-susceptible
Staphylococcus aureus, Pseudomonas aeruginosa and Aspergillus section Fumigati whereby is
under chronic suppression therapy with two inhaled antibiotics. Recently, there has been
a progressive clinical respiratory functional deterioration. In a periodic evaluation, a miccrobiology control sputum was requested. Sample was cultured, in parallel, for bacteriol ogy and mycology evaluation.
Results: Apart from detection of S. aureus and Raoultella ornithinolytica, after 3-5 days
of incubation at 37ºC, the cultures showed several cream-coloured colonies, powdery to
velvety. Microscopic examination showed hyaline septate hyphae, Penicillium-like conid iophores with rough wall, ovoid to cylindrical phyalides with a narrow neck and cylin drical unicellular smooth-walled microconidia, arranged in unbranched basipetal chains arising from phialides.
The isolate was identified as Rasamsonia argillacea species complex based on its mor phology and confirmed by MALDI-TOF mass spectrometry. As no septate hyphae were
seen on direct examination, a new sample was requested to exclude extrinsic contamina tion. The second sample was inoculated as previously, confirming the persistent presence
of Rasamsonia argillacea species complex in the sputum of this patient. The identification
of this isolate was further confirmed by sequencing the internal transcribed spacer (ITS)
region of ribosomal DNA, showing 100% homology with sequences deposited on data bases. Antifungal susceptibility testing showed high minimal inhibitory concentrations
(MIC) to almost all tested antifungals (posaconazole, voriconazole, amphotericin B) and
low MIC to anidulafungin. The patient had no great exacerbation of his respiratory prob lems and the isolated fungus was interpreted as colonization being the patient under more
frequent surveillance.
Conclusion: Although colonization of the upper respiratory tract in CF patients by
R. argillacea species complex has been described as an emerging situation, the role of these
fungi in clinical or functional deterioration of the disease remains controversial. Indeed,
data about its real prevalence in the CF population are lacking. However, taking into ac count the ability of this species to predominantly affect the lungs, to induce pneumonia and to disseminate to adjacent organs or even to the central nervous system (CNS) in imunocompromised patients, it is essential to promote its accurate identification that is often misidentified as Penicillium spp. or Paecilomyces species. Antifungal susceptibility
testing should be performed for epidemiological purposes and to guide therapy, as Rasamsonia spp. usually presents a marked antifungal resistance profileinfo:eu-repo/semantics/publishedVersio
Survey of extended-spectrum beta-lactamases in Escherichia coli isolates from a Portuguese hospital and characterisation of a novel class 1 integron (In60A) carrying the bla(CTX-M-9) gene
Between November 2001 and November 2004, 231 Escherichia coli isolates resistant to P-lactam antibiotics were identified. In 14 isolates, bla(TEM-24) (2 isolates), bla(TEM-52) (5 isolates) and bla(TEM-26) (7 isolates) were identified. In 145 E. coli isolates with the same M13 fingerprinting profile and the same resistance phenotype, the bla(CTX-M-15) gene was found in association with an insertion sequence ISEcp1. The bla(CTX-M-2) gene was identified in one E. coli isolate (290HSM), and in other E. coli isolate (246HSM) the bla(CTX-M-9) gene was contained in a new complex sull-type class 1 integron (named In60A). This is the first report of three cefotaximases (CTX-M-15, CTX-M-2 and CTX-M-9) in E. coli isolates from a Portuguese hospital. (c) 2006 Elsevier B.V. and the International Society of Chemotherapy.

Subcutaneous phaeohyphomycosis due to Phaeoacremonium parasiticum in a patient with Chronic Granulomatous Disease
Abstract publicado em J Fungi. 2021;7(11):213-14 (P252). https://doi.org/10.3390/jof7110Objectives: Phaeoacremonium parasiticum is a ubiquitous dematiaceous mold that
rarely causes infection in humans. Its spectrum of disease ranges from subcutaneous
infections to disseminated disease. The majority of those reported few cases involve
immunocompromised patients. Chronic granulomatous disease (CGD) is an inherited disorder affecting nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex.
CGD patients are susceptible to a broad spectrum of opportunistic infections, being fungal
infections a major determinant of survival. We report a case of Subcutaneous phaeohyphomycosis due to P. parasiticum in a young adult with CGD.
Material and methods: A 28-year-old male patient with autossomic recessive CGD,
due to mutations in CYBA, is followed in Primary Immunodeficiency Center since childhood. He has been under prophylaxis with itraconazole, cotrimoxazole and IFNg and
tapering oral steroids, started for granulomatous colitits 2 years earlier.
In a regular visit to the clinical center, he complained of persistent pain on his left leg
with no history of recent injury in the affected area and without external inflammatory
signs. An ultrasound was performed after 2 weeks revealing a heterogeneous liquid of
slightly irregular contour in the sinus of the left anterior tibial muscle with heterogeneity of
the adjacent muscle. This piomiositis collection was punctured, under ultrasound control,
with drainage of about 7cm3 of hemato-purulent exsudate that was promptly processed
for bacteriology (aerobic and anaerobic) and mycology studies.
Results: Cultures for bacteria were sterile. Culture on Sabouraud was positive after
5 days of incubation, showing slow growing and initially white colonies. Microscopic
examination showed hyaline, septate mycelium with long, thin conidiophores and curved,
aseptate conidia.The fungus was initially identified as an Acremonium sp. and was sent to
the Mycology Reference Laboratory for molecular identification and antifungal susceptibility testing. Its identification was performed by sequencing the internal transcribed spacer
(ITS) region of ribosomal DNA, being the isolate identified as Phaeoacremonium parasiticum
(100% homology).
After 3 weeks incubation, coloration of the colonies emerged, becoming greyish black
upon subculture, with velvety texture and black reverse. Microscopically, pigmented
hyphae with tapering, funnel-shaped phialides were observed, and conidia were hyaline
and oblong, forming clusters at the tip of the phialides. At this point, macroscopic and
microscopic morphology was consistent with Phaeoacremonium species.
Susceptibility pattern showed low minimal inhibitory concentrations (MIC) to posaconazole and voriconazole, and higher MIC values to anidulafungin and amphotericin B. The
patient has improved under voriconazol therapy (200 mg; bid)
Conclusions: Phaeoacremonium parasiticum is an uncommon infection and its appropriate identification is often difficult because morphologically, the genus Phaeoacremonium
show morphological features resembling both Acremonium and Phialophora genera.
Molecular identification is determinant to confirm morphology, as many species
have indistinguishable characteristics that may lead to incorrect antifungal options. Also,
susceptibility testing should be done for these so rare fungi as optimal treatment has not
yet been clearly defined.info:eu-repo/semantics/publishedVersio
