Objective. To confirm the absence of Wuchereria bancrofti autochthonous cases in Manaus, a former focus of lymphatic filariasis in the Western Brazilian Amazon. Methods. A field survey was carried out in 2016 using immunochromatographic rapid tests (ICT card) for the detection of circulating filarial antigens in blood. The sample included a group of 3 000 schoolchildren aged 6 to 10 years enrolled in schools from different urban areas of Manaus (including the former lymphatic filariasis focus in the city) and a group of 709 adolescents and adults, between the ages of 11 and 85 years, born and raised in different areas of Manaus. Results. All of the individuals tested negative for W. bancrofti antigen. Conclusions. Although Manaus was once considered endemic, this focus no longer seems to be active for lymphatic filariasis transmission. The results of this study could support the certification by the World Health Organization of the lymphatic filariasis transmission elimination exercise in Brazil.

Background: The study on lymphatic filariasis (LF) in Igbo-Eze North was conducted to determine the prevalence and predisposing factors to LF among its residents between May and October 2018. Methods: A total of 201 residents who have lived in the area for at least one year were recruited. They were stratified according to age, gender and occupation, and were clinically examined firstly by rapid assessment method for any lymphoedema and hydrocele. At recruitment, blood samples were collected from all volunteered participants for LF test. In addition, demographic information and risk factors of the respondents were captured using a structured questionnaire by oral interview. Results: The overall prevalence for LF was 84 (41.8%). Furthermore, LF prevalence was significant (P < 0.05) in all the studied communities: 61.5% in Umuogbuagu, 48.1% in Aguibege, 32.7% in Umuagama and 21.7% in Umuopu. The sex-related prevalence of LF was higher among females than males, with slight significant difference (P = 0.046). In relation to age and occupation, higher prevalences (P < 0.0001) were recorded among older (≥ 50 years) subjects (49, 61.2%) and traders (55, 57.9%) respectively. The risk associated with LF implicated lack of knowledge, non-use of mosquito nets, as well as visit and proximity to water bodies as major predispositions (P < 0.05). Conclusion: The prevalence of LF in this study was high. Higher prevalence was among females, older people and traders. Notable risks to the disease outcome are environmental, attitudinal and occupational with chances of scaled up prevalence and burden overtime.

Dyckia walteriana is a recently described rupicolous bromeliad, whose only officially known population is located on a basaltic outcrop in the Serra Geral formation, north of Paraná state, Brazil. Unfortunately, the population of the type locality was dramatically reduced in 2018 by an intentional fire. The main objectives of this work were to know the geographical distribution of D. walteriana, seeking the registration of new populations, and, through a rapid assessment, establish the risk of extinction of each one. We selected 40 sites with rocky outcrops located between the third and second plateaus of Paraná state, Brazil, within the Serra Geral formation. Twelve populations of D. walteriana were found occupying “islands” of basaltic rocks. The extent of occurrence of the species corresponds to a polygon of 533 km2, with an occupancy area of 0.71 km2. Of the 12 populations, only four presented no or low risk of extinction, while eight presented medium to extreme risk of extinction in the next 10 years. D. walteriana falls into the category “critically endangered”, demanding urgent measures for the conservation of relictual populations.
