Assessing the role of individual foxes in environmental contamination with Echinococcus multilocularis through faecal samples
Int J Parasitol. 2024 Mar 7:S0020-7519(24)00053-5. doi: 10.1016/j.ijpara.2024.03.003. Online ahead of print.ABSTRACTKey parasite transmission parameters are difficult to obtain from elusive wild animals. For Echinococcus multilocularis, the causative agent of alveolar echinococcosis (AE), the red fox is responsible for most of the environmental contamination in Europe. The identification of individual spreaders of E. multilocularis environmental contamination is crucial to improving our understanding of the ecology of parasite transmission in areas of high endemicity and optimising the effectiveness of prevention and contr...

Identification and exploration of a new M2 macrophage marker MTLN in alveolar echinococcosis
In this study, CIBERSORT and WGCNA algorithms were used to establish a weighted gene co-expression network, and MTLN was identified as a biological marker of M2-type macrophages, which participated in energy metabolism of macrophages and mediated inflammatory response, but the role of MTLN in AE was not studied. In this study, liver tissue samples from AE patients were collected and immunofluorescence co-localization showed the relationship between MTLN and macrophage distribution. E. multilocularis infected mouse model was established to analyze the expression of MTLN, liver fibrosis, and inflammatory reaction after E. mu...

Primary seronegative intermuscular hydatidosis in a child, an infection that should be approached like a tumor: a case report and review of the literature
ConclusionHydatid cysts should always be considered in the differential diagnosis of soft tissue cystic masses in endemic areas, and aspiration or drainage should be avoided as much as possible, even when serological tests are negative and imaging is non-diagnostic. In cases where the diagnosis of a hydatid cyst has been confirmed before the surgery, it is recommended to approach the cyst, like a tumor with chemotherapy using Albendazole both before and after wide cyst excision.

Multiple Cerebral Hydatic Cyst Developed After Operation of Cardiac Hydatic Cyst: A Case Report
Turkiye Parazitol Derg. 2024 Mar 5;48(1):62-65. doi: 10.4274/tpd.galenos.2024.18480.ABSTRACTHydatid cyst is a zoonotic disease and is an important health problem, especially in developing countries. Hydatic cysts are typically observed in the liver and lungs. Cardiac and brain involvement are rare manifestations. Cardiac hydatic cysts are usually located in the left ventricle. Brain involvement is frequently seen as a primary cerebral cyst and is almost always solitary. However, secondary intracerebral cysts are also seen as a result of cardiac cysts rupturing into the left ventricle spontaneously or iatrogenically, and th...

Epidemiology and Clinical Characteristics of Cerebral Alveolar Echinococcosis in the Tibetan Region of Sichuan, China
This study aimed to examine the epidemiology and clinical characteristics of cerebral alveolar echinococcosis in the Tibetan region of Sichuan, China. A retrospective analysis of hospitalized cases of cerebral alveolar echinococcosis from six medical units in the Garze Tibetan Autonomous Prefecture, Sichuan Province, from January 2016 to June 2021 was conducted. The study focused on the characteristics, clinical presentation, and imaging features of the disease. Of 119 cerebral alveolar echinococcosis patients, 76 were male and 43 were female. Occupationally, 62 were farmers, 46 were herdsmen, nine were monks, and two were...

The A2 haplotype of Echinococcus multilocularis is the predominant variant infecting humans and dogs in Yili Prefecture, Xinjiang
In this study, 127 samples were used for haplotypes analysis, including 79 tissues from humans, 43 liver tissues from small rodents, and 5 fecal samples from dogs. Genetic variability in E. multilocularis was studied using complete sequences of the mitochondrial (mt) genes of cytochrome b (cob), NADH dehydrogenase subunit 2 (nad2), and cytochrome c oxidase subunit 1 (cox1), using a total of 3558 bp per sample. The Asia haplotype 2 (A2) was the dominant haplotype, with 72.15% (57/79) prevalence in humans, 2.33% (1/43) in small rodents, and 80.00% (4/5) in dogs, followed by A5, the second most common haplotype, which infecte...
