The coronavirus SARS-CoV-2 (COVID-19) pandemic led to major restrictions in daily life and social contacts in Finland in March 2020. The effect of these restrictions on sexually transmitted infections (STIs) is unclear. The aim of this study was to analyse the incidence and positive rates of sexually transmitted infections in Northern Finland betwe...
Background: Syphilis is a highly contagious, systemic bacterial illness that poses a serious public health threat on a worldwide scale. In addition to being spread sexually, the illness can also be contracted through blood donation. To accurately evaluate the epidemiological pattern and community impact of the disease, this research sought to ascer...
Syphilis is considered one of the greatest imitators which
can mimic any skin disease. Keen examination together with a sound
brain and a high degree of suspicion is required for its diagnosis.
Syphilis, a sexually transmitted disease caused by spirochete Treponema
pallidum pallidum, was more common during the Second
World War. Later, as the human...
Syphilis continues to be a significant global health concern, and understanding the latest advancements in immunology and pharmacological treatment is crucial for effective disease management. This review article provides an in-depth exploration of these advancements, aiming to contribute to the growing body of knowledge on syphilis research. The e...
In this work, we determined that Treponema pallidum subsp. pallidum (TPA) DAL-1 (belonging to Nichols-like group of TPA strains) grew 1.53 (± 0.08) times faster compared to TPA Philadelphia 1 (SS14-like group) during in vitro cultivations. In longitudinal individual propagation in rabbit testes (n = 12, each TPA strain), infection with DAL-1 manife...

... Diferentes abordagens arqueológicas nos trazem evidências dos impactos das ações humanas nos ecossistemas. Estudos bioarqueológicos e biomoleculares, sobretudo de paleopatologias e análises genéticas, podem identificar doenças ligadas a vírus e bactérias no passado (Prümers et al., 2012). Estudos arqueobotânicos e paleoecológicos podem registrar a abertura da cobertura vegetal para fins diversos, transformando completamente comunidades de plantas e consequentemente de animais que estavam naquele local (Brown; Pluskowski, 2014; Kozáková et al., 2014;Watling et al., 2017). ...
Recentes associações entre a emergência da pandemia mundial por conta do
novo coronavírus (2019-nCoV) e sua relação direta com o consumo de animais
silvestres nos motivaram a escrita deste trabalho. Este ensaio busca trazer uma
reflexão sobre a longa e intensa interação que humanos e outros animais mantêm
e como essa proximidade trouxe mudanças bioevolutivas para ambos, sobretudo
nos últimos 10 mil anos. Assim, procuramos discutir alguns exemplos da presença
de morcegos e do consumo de animais silvestres em sítios arqueológicos, buscando
explicitar como as relações entre sociedades, animais e ambientes mudaram
ao longo do tempo e como o avanço acelerado da antropização dos ecossistemas
têm provocado impactos, levando a desequilíbrios que facilitam a transmissão de
patógenos entre diferentes espécies. Desejamos igualmente demonstrar a importante
contribuição dos estudos zooarqueológicos aos debates atuais sobre alternativas
de construção de relações sociedades-natureza.
... Fluctuations in the fish spectrum observed from phases 3 to 4 and 4 to 5 may be related to cultural and/or landscape transformations occurring around 1100 AD in Loma Salvatierra. This is suggested by evidence of reconfiguration of the site and material culture observed by Prümers et al. (2012) and Jaimes Betancourt (2016) [40,41]. ...

Recent evidence suggests the existence of Pre-Hispanic fisheries in savanna areas of the Amazon basin. How these fisheries may have functioned is still poorly known. Although many studies have drawn attention to how Pre-Hispanic inhabitants of these savannas managed to deal with excess water, little attention has been paid to understanding how large and permanent populations were sustained during long periods of drought. In the Llanos de Mojos, one of the largest savannas in South America, the landscape is greatly affected by the impacts of annual, seasonal flooding and inundations, alternating with a dry period that can last 4–6 months. The fishing practices in this area were studied on the basis of analysis of more than 17,000 fish remains recovered at Loma Salvatierra, a monumental mound located in an interfluvial area 50 km from the Mamoré River and occupied between 500 and 1400 AD. In Loma Salvatierra, a network of circular walled ponds connected to a system of canals has been identified, raising questions about a possible use of these structures for fishing. The exceptional conservation of the bone material has enabled precise taxonomic identification of more than 35 taxa, the richest fish spectrum thus far documented in the Mojos region. The dominant fish, swamp-eels (Synbranchus spp.), armored catfishes (Hoplosternum spp.), lungfish (Lepidosiren paradoxa), and tiger-fish (Hoplias malabaricus) are characteristic of shallow and stagnant waters. Our work documents the first zooarchaeological evidence of a dryland, interfluvial fishing system in the Bolivian Amazon that incorporates distinct species and fishing practices, demonstrating that these regions contain year round resources. Research is taking its first steps toward understanding landscape modifications, fish environments, and specific cultural technologies employed on this and other lowland neotropical savannas that differ from those for fishing in open waters and rivers.
Syphilis was perceived to be a new disease in Europe in the late 15th century, igniting a debate about its origin that continues today in anthropological, historical, and medical circles. We move beyond this age‐old debate using an interdisciplinary approach that tackles broader questions to advance the understanding of treponemal infection (syphilis, yaws, bejel, and pinta). How did the causative organism(s) and humans co‐evolve? How did the related diseases caused by Treponema pallidum emerge in different parts of the world and affect people across both time and space? How are T. pallidum subspecies related to the treponeme causing pinta? The current state of scholarship in specific areas is reviewed with recommendations made to stimulate future work. Understanding treponemal biology, genetic relationships, epidemiology, and clinical manifestations is crucial for vaccine development today and for investigating the distribution of infection in both modern and past populations. Paleopathologists must improve diagnostic criteria and use a standard approach for recording skeletal lesions on archaeological human remains. Adequate contextualization of cultural and environmental conditions is necessary, including site dating and justification for any corrections made for marine or freshwater reservoir effects. Biogeochemical analyses may assess aquatic contributions to diet, physiological changes arising from treponemal disease and its treatments (e.g., mercury), or residential mobility of those affected. Shifting the focus from point of origin to investigating who is affected (e.g., by age/sex or socioeconomic status) and disease distribution (e.g., coastal/ inland, rural/urban) will advance our understanding of the treponemal disease and its impact on people through time.
