Background: Most cystic echinococcosis cases in Southern Brazil are caused by Echinococcus granulosus and Echinococcus ortleppi. Proteomic studies of helminths have increased our knowledge about the molecular survival strategies that are used by parasites. Here, we surveyed the protein content of the hydatid fluid compartment in E. granulosus and E. ortleppi pulmonary bovine cysts to better describe and compare their molecular arsenal at the host-parasite interface.
Methods: Hydatid fluid samples from three isolates of each species were analyzed using mass spectrometry-based proteomics (LC-MS/MS). In silico functional analyses of the identified proteins were performed to examine parasite survival strategies.
Results: The identified hydatid fluid protein profiles showed a predominance of parasite proteins compared to host proteins that infiltrate the cysts. We identified 280 parasitic proteins from E. granulosus and 251 from E. ortleppi, including 52 parasitic proteins that were common to all hydatid fluid samples. The in silico functional analysis revealed important molecular functions and processes that are active in pulmonary cystic echinococcosis, such as adhesion, extracellular structures organization, development regulation, signaling transduction, and enzyme activity.
Conclusions: The protein profiles described here provide evidence of important mechanisms related to basic cellular processes and functions that act at the host-parasite interface in cystic echinococcosis. The molecular tools used by E. granulosus and E. ortleppi for survival within the host are potential targets for new therapeutic approaches to treat cystic echinococcosis and other larval cestodiases.

Background: Hepatic abscesses represent infections of the liver parenchyma from bacteria, fungi, and parasitic organisms. Trends in both abscess microbiology and management of abscesses (infective collections) have changed over the past decade. There is a paucity of published data regarding the clinicopathological features of liver abscesses in sub-Saharan Africa and other low-income and middle-income countries.

Introduction: Cystic Echinococcosis (CE), caused by Echinococcus granulosus, primarily affects the liver and lungs, particularly in endemic regions. While commonly associated with gastrointestinal manifestations, CE can lead to severe complications that necessitate surgical intervention.
Case Presentation: A 53-year-old female was referred due to a prolonged history of exertional dyspnea that recently worsened.

Introduction: Echinococcosis is a relatively widespread anthropozoonosis in endemic regions, preferentially affecting the liver and lungs. Although rare, it can sometimes be localized in the muscles. The clinical symptoms are insidious and not very indicative, often leading to a delayed diagnosis.
