AI Article Synopsis
- The study aimed to evaluate serodiagnosis of hydatid cysts in humans using sheep antigens through ELISA and compare this with a commercial kit.
- One hundred blood samples were collected from patients with severe abdominal pain and were tested with different sheep antigens to detect antibodies, using known positive and negative controls for validation.
- The findings indicated that hydatid fluid antigen was the most effective for detection, showing greater compatibility in the analysis, thus suggesting its potential for further ELISA diagnostic development for hydatidosis in humans.
Article Abstract
Objective: To explore the serodiagnosis of hydatid cyst in human using different antigens of sheep (hydatid fluid, Somatic and Excretory/secretory antigens of protoscolex) by ELISA and compares this result with commercial human ELISA kit.
Methods: One hundred blood samples from patients with history of severe abdominal pain and eosinophilia were obtained. Ten serum samples were obtained from surgically and pathologically confirmed cystic echinococcosis patients from Mashhad university hospital as positive control and 5 serum samples from infant under one year old as negative control. Blood samples were centrifuged at 3 000μg at 20 °C for 15 min and sera were stored at -20 °C. First, these samples were tested for the presence of antibody by commercial human ELISA. Then, ELISA was developed on microplates coated with hydatid fluid, Somatic and Excretory/secretory antigens of protoscolex of sheep.
Results: The results of this study as analyzed by Kappa test showed that, hydatid fluid antigen could be used as a precise source of detection in indirect ELISA test.
Conclusions: Hydatid fluid in comparison with Excretory-secretory and somatic antigens showed more compatibility agreement in kappa test which can be used for further studies in development of any ELISA test for diagnosis of human hydatidosis.

Protective effects of hydatid cyst fluid on inflammation and tissue damage in rat model of type 1 diabetes.

Cystic echinococcosis, caused by Echinococcus granulosus, is a zoonotic disease with immunomodulatory properties attributed to hydatid cyst fluid (HCF). Given the immune-modulating and anti-inflammatory properties of HCF observed in other contexts, its potential therapeutic effects in diabetes remain unexplored. This study aimed to investigate the potential therapeutic effects of HCF on glycemic control, inflammatory cytokines, and tissue histopathology in a streptozotocin (STZ)-induced model of type 1 diabetes.

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.

Article Synopsis
- Hydatid disease, caused by the Echinococcus parasite, is a serious health issue in endemic areas, and breast involvement is notably rare; this case involves a 34-year-old Ethiopian woman initially misdiagnosed with breast cancer.
- The patient presented with a painless swelling in her left breast that persisted for nine months, without symptoms typically associated with cancer, such as discharge or skin changes.
- Diagnostic imaging and tests ultimately confirmed that the mass was a hydatid cyst, highlighting the need for healthcare professionals to consider less common conditions in their diagnosis of breast masses in endemic regions.

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.
