Atypical presentation of entomophthoromycosis caused by Conidiobolus coronatus

A male patient from Guinea-Bissau was admitted to Egas Moniz Hospital, Lisbon, complaining of fever and exhibiting a productive cough with mucopurulent discharge and weight loss. He had been using empirical medication with dexamethasone to treat his generalized facial swelling.

Unusual coexistence of opportunistic lung infections in a human immunodeficiency virus positive patient suffering from persistent pneumocystis jirovecii pneumonia: A case report

It is well-established that HIV patients are at high risk of opportunistic infections (OI), like the ones caused by Pneumocystis jirovecii, a worldwide pathogen implicated in interstitial pneumonia (PcP). We present a case of a newly diagnosed HIV-1 patient with multiple OI, including a persistent form of PcP, an invasive aspergillosis (IA), cytomegalovirus and Mycobacterium xenopi lung infection. We describe the combination of laboratorial screening, surgery and antimicrobial therapy which were crucial for patient recovery.

Pneumocystis jirovecii multilocus genotyping in pooled DNA samples: a new approach for clinical and epidemiological studies.

Specific single-nucleotide polymorphisms (SNPs) are recognized as important DNA sequence variations influencing the pathogenesis of Pneumocystis jirovecii and the clinical outcome of Pneumocystis pneumonia, which is a major worldwide cause of illness among immunocompromised patients

Population structure of Pneumocystis jirovecii isolated from immunodeficiency virus-positive patients

Pneumocystis jirovecii pneumonia (PcP) is an important opportunistic infection among immunocompromised patients. Genetic characterization of P. jirovecii isolated from HIV-positive patients, based on identification of multiple nucleotide sequences at eight distinct loci, was achieved by using PCR with DNA sequencing and RFLP.

Identification of relevant single-nucleotide polymorphisms in Pneumocystis jirovecii: relationship with clinical data

Pneumocystis jirovecii is a poorly understood pathogen that causes opportunistic pneumonia (Pneumocystis pneumonia (PcP)) in patients with AIDS.

The demise of multidrug- resistant HIV-1: The national time trend in Portugal

Despite a decreasing mortality and morbidity in treated HIV-1 patients, highly active antiretroviral treatment (HAART) can still fail due to the development of drug resistance. Especially, multidrug-resistant viruses pose a threat to efficient therapy. We studied the changing prevalence of multidrug resistance (MDR) over time in a cohort of HIV-1-infected patients in Portugal.

Decreasing population selection rates of resistance mutation K65R over time in HIV-1 patients receiving com- bination therapy including tenofovir

The use of tenofovir is highly associated with the emergence of mutation K65R, which confers broad resistance to nucleoside/nucleotide analogue reverse transcriptase inhibitors (NRTIs), especially when tenofovir is combined with other NRTIs also selecting for K65R. Although recent HIV-1 treatment guidelines discouraging these combinations resulted in reduced K65R selection with tenofovir, updated information on the impact of currently recommended regimens on the population selection rate of K65R is presently lacking.

Lymphogranuloma venereum serovar L2b in Portugal

Chlamydia trachomatis, serovar L2, is the causative agent of lymphogranuloma venereum (LGV), which during recent years has been responsible for various outbreaks reported among men who have sex with men (MSM) in Western Europe, America, Canada and Australia.

Angola’s 2013 dengue outbreak: clinical, laboratory and molecular analyses of cases from four Portuguese institutions

Dengue virus (DENV) is the arbovirus with the widest impact on human health. In Africa in general, and in Angola in particular, the epidemiology and public health impact of DENV is far from clear. However, rapid population growth, unplanned urbanization, increased international travel, and the presence of virus major vector (Aedes aegypti) in the country suggest that DENV transmission may occur.

Insights on the genotype distribution among Cryptococcus neoformans and C. gattii Portuguese clinical isolates

This study provides a comprehensive picture of the C. neoformans/C. gattii molecular types most often associated with human cryptococcosis in Portugal and assesses the impact of C. gattii in these infections. One hundred and twenty-two clinical isolates, from distinct patients, were identified as C. neoformans and genotyped by URA5-RFLP, with the molecular types VNI (45.5 %) and VNIII (30.9 %) being the most commonly found ones.
