Monkeypox virus infection in HIV-1- coinfected patients previously vaccinated a...
Brazão, C.; Garrido, P.M.; Alpalhão, M.; Roda, A.; Vieitez-Frade, J.; Ferreira, J.A.; Pelerito, A.; Lopes de Carvalho, I.; Cordeiro, R.; Borrego, M.J.Monkeypox is a zoonotic orthopoxvirus that incidentally causes disease in humans similar to smallpox, although with lower mortality. This virus is endemic to western and central Africa, with outbreaks in occidental countries related to exotic pet trade and international travel. Coincident immunity to monkeypox virus was previously achieved with vaccinia virus vaccination; however, eradicating smallpox and subse...
A Multidisciplinary Approach to the First Autochthonous Case of Tularemia Repor...
Cunha, F.; Lopes de Carvalho, I.; Torres, C.; Gonçalves, R.Francisella tularensis, a Gram-negative coccobacillus, is a highly virulent pathogen responsible for several zoonotic outbreaks in Europe in the last few decades. The authors report the case of a 46-year-old male who developed fever, myalgias and headache a week after having contact with animal feed contaminated by rodents. Serological tests were positive for Francisella tularensis. This first case of autochtho...
Outbreak of monkeypox in an STD clinic in Lisbon
Caldeira, M.; Fernandes, C.; Neves, J.; João, A.; Calado, R.; Pinto, A.R.; Borrego, M.J.; Cordeiro, R.; Machado, J.; Pelerito, A.; Lopes de Carvalho, I.We present the preliminary results of the first 43 patients with a definitive diagnosis of human infection with monkeypox virus, from the dermatovenereology department of Hospital Santo António dos Capuchos, Lisbon, in May 2022 [...].
Effects of stress exposure in captivity on physiology and infection in avian ho...
Norte, A. C.; Araújo, P. M.; Augusto, L.; Guímaro, H.; Santos, S.; Lopes, R. J.; Núncio, M. S.; Ramos, J. A.; Lopes de Carvalho, I.Exposure to environmental stressors, an increasingly recurring event in natural communities due to anthropogenic-induced environmental change, profoundly impacts disease emergence and spread. One mechanism through which this occurs is through stress-induced immunosuppression increasing disease susceptibility, prevalence, intensity and reactivation in hosts. We experimentally evaluated how exposure to stressors ...
Ongoing monkeypox virus outbreak, Portugal, 29 April to 23 May 2022
Duque, M.P.; Ribeiro, S.; Martins, J.V.; Casaca, P.; Leite, P. P.; Tavares, M.; Mansinho, K.; Duque, L.M.; Fernandes, C.; Cordeiro, R.; Borrego, M.J.Up to 27 May 2022, Portugal has detected 96 confirmed cases of monkeypox. We describe 27 confirmed cases (median age: 33 years (range: 22–51); all males), with an earliest symptom onset date of 29 April. Almost all cases (n = 25) live in the Lisbon and Tagus Valley health region. Most cases were neither part of identified transmission chains, nor linked to travel or had contact with symptomatic persons or with ...
Diversity of microorganisms in Hyalomma aegyptium collected from spur-thighed t...
Norte, A.C.; Harris, D.J.; Silveira, D.; Nunes, C.S.; Núncio, M.S.; Martínez, E.G.; Giménez, A.; Sousa, R.; Lopes de Carvalho, I.; Perera, A.Ticks carry a diverse community of microorganisms including non-pathogenic symbionts, commensals, and pathogens, such as viruses, bacteria, protozoans, and fungi. The assessment of tick-borne microorganisms (TBM) in tortoises and their ticks is essential to understand their eco-epidemiology, and to map and monitor potential pathogens to humans and other animals. The aim of this study was to characterize the div...
The Population Structure of Borrelia lusitaniae Is Reflected by a Population Div...
Norte, A.C.; Boyer, P.H.; Castillo-Ramirez, S.; Chvostac, M.; Brahami, M.O.; Rollins, R.E.; Woudenberg, T.; Didyk, Y.M.; Derdakova, M.; Núncio, M.S.Populations of vector-borne pathogens are shaped by the distribution and movement of vector and reservoir hosts. To study what impact host and vector association have on tick-borne pathogens, we investigated the population structure of Borrelia lusitaniae using multilocus sequence typing (MLST). Novel sequences were acquired from questing ticks collected in multiple North African and European locations and were...

A importância dos artrópodes ixodídeos para a Saúde Pública na Região de Saúde ...
Torres, C.; Santos, A.S.; Lopes de Carvalho, I.; Gomes, F.; Serrada, E.; Gonçalo, J.; Codeiro, E.; Menezes de Almeida, L.; Tavares, A.; Santos Silva, M.As doenças transmitidas por vetores têm reemergido → alterações climáticas, demográficas, genéticas nos agentes patogénicos, resistências a inseticidas e mobilidade de populações e bens. Os ixodídeos são um dos vetores com mais impacto na Saúde Pública. Este estudo pretende caracterizar a distribuição de ixodídeos por critérios temporo-espaciais, ambientais e parasitismo, no âmbito da Rede de Vigilância de Veto...
Paralytic Shellfish Poisoning due to ingestion of contaminated mussels: a case r...
Ribeiro, I.; Pelerito, A.; Cordeiro, R.; Vale, P.; Núncio, M.S.; Lopes de Carvalho, I.In Portugal, the potent paralytic shellfish toxins (PSTs) have appeared irregularly since the onset of a national monitoring program for marine biotoxins in 1986. In years where high contamination levels were attained in bivalves, sporadic cases of human poisonings have been recorded, as in 1994 and 2007. The reappearance of high contamination levels led to the appearance of new cases during the autumn of 2018....
