Cystic and alveolar echinococcosis are severe zoonotic diseases characterized by long asymptomatic periods lasting months or years. Viable Echinococcus spp. eggs released into the environment through the feces of canids can infect humans through accidental ingestion via hand-to-mouth contact or consumption of contaminated food or water.

The island of Cyprus was a historical endemic area for cystic echinococcosis (CE) in the Mediterranean. During the last decades, Cyprus has been an open-air laboratory and a model for testing and implementing control measures aiming to eliminate CE as a public health problem. Despite control and surveillance measures implemented during last 50 years, molecular characterization of specimens has been never provided.

Article Synopsis
  • Echinococcus multilocularis is a parasitic cestode causing a deadly disease called alveolar echinococcosis, primarily spread by red foxes in Europe.
  • The study investigated genetic diversity among E. multilocularis isolates from 19 European countries, analyzing 4,968 base pairs from five mitochondrial genes and identifying 43 different haplotypes.
  • Findings indicated that most of the isolates shared four predominant haplotypes concentrated in mainland Europe, while Svalbard's isolates were genetically distinct, highlighting the need for more research in underrepresented eastern European regions to understand genetic variability.

Article Synopsis
  • Human cystic echinococcosis (CE) is a parasitic infection caused by Echinococcus granulosus, primarily affecting the liver and lungs, but it can also rarely impact the central nervous system (CNS), leading to cerebral CE (CCE), which poses significant clinical challenges.
  • A case study in a child from near Rome, Italy revealed that the CCE was caused by the E. granulosus s.l. complex, likely transmitted from local sheep, and a literature review highlighted 2,238 CCE cases, predominantly affecting children with a high occurrence of single cysts in the brain.
  • The findings indicate that CCE, though rare, has severe implications for patient health and should be fact

Background: Cystic echinococcosis (CE), a widespread helminthic disease caused by the larval stage of the dog tapeworm Echinococcus granulosus represents a public health concern in humans. Albendazole (ABZ) is the first-line treatment for CE; however therapeutic failure of ABZ against CE occurs because of size and location of formed cysts as well its low aqueous solubility and consequently its erratic bioavailability in plasma. Serious adverse effects have also been observed following the long-term use of ABZ in vivo.

Article Synopsis
  • Cystic echinococcosis (CE) is a neglected parasitic disease caused by Echinococcus granulosus, affecting rural communities in Latin America, particularly in Chile’s Coquimbo region, where many cases go undiagnosed.
  • A community-based study in 2019 used abdominal ultrasound to screen 2,439 residents, revealing a CE prevalence of 1.6%, with higher infection rates in rural areas, older individuals, and those consuming non-potable water.
  • The study indicates that a significant portion of infected individuals were newly diagnosed, with both active and inactive cysts found among different age groups; this research highlights the need for better recognition and management of CE cases in the region.

Among echinococcoses diseases of human interest, two have a global public health impact: cystic and alveolar echinococcosis caused by and , respectively. Cystic and alveolar echinococcosis are neglected infectious diseases epidemiologically and are clinically vastly different with distinct microscopic features. Because of the rareness of these zoonotic diseases, pathologists have limited diagnostic experience in the analysis of the lesions caused by tapeworms.

Article Synopsis
  • - The study investigated the prevalence of cystic echinococcosis (CE), a parasitic disease, in the towns and rural areas of Ñorquinco and Ramos Mexia, Argentina, finding an infection rate of 4.7% among 892 volunteers screened by ultrasound.
  • - Significant risk factors for CE included living in rural areas, being over 60 years old, drinking from natural water sources, frequently touching dogs, and having lived in a rural setting during childhood.
  • - The findings suggest that CE infections are often acquired in childhood and are influenced by ongoing exposure to environmental contamination in rural areas.

Repurposing of approved non-antitumor drugs represents a promising and affordable strategy that may help to increase the repertoire of effective anticancer drugs. Benzimidazole-based anthelmintics are antiparasitic drugs commonly employed both in human and veterinary medicine. Benzimidazole compounds are being considered for drug repurposing due to antitumor activities displayed by some members of the family.

The cestode Echinococcus multilocularis is the causative agent of alveolar echinococcosis, a severe helminthic zoonotic disease distributed in the Northern Hemisphere. The lifecycle of the parasite is mainly sylvatic, involving canid and rodent hosts. The absence of genetic data from most eastern European countries is a major knowledge gap, affecting the study of associations with parasite populations in Western Europe.

A direct enantio-, diastereo-, and chemo-selective high-performance liquid chromatographic method was developed for determining the content, enantiomeric purity, and related substances of the chiral antidepressant drug sertraline HCl in a single chromatographic run. The separation was achieved on a chiral stationary phase based on amylose tris(3-chloro-5-methylphenylcarbamate) under reversed-phase conditions. The method was optimized by evaluating the influence of the temperature and mobile phase composition on the retention and selectivity.

Cystic echinococcosis (CE) is a neglected zoonotic disease caused by Echinococcus granulosus sensu lato. Diagnosis and monitoring of CE rely primarily on imaging while serology is used as a confirmatory test. However, imaging is not always conclusive and currently available serological assays have suboptimal sensitivity and specificity, lack standardization, and are not useful for patients´ follow-up.

Infections with eggs of () can cause cystic echinococcosis in intermediate host animals and humans. Upon ingestion of viable eggs, oncospheres hatch from the eggs and subsequently develop into fluid-filled larval cysts, most frequently in the liver or the lungs. The slowly growing cysts progressively interfere with organ function.
