The current prevalence and diversity of cystic echinococcosis in slaughtered animals in Egypt

AbstractCystic echinococcosis is a potential zoonotic helminthic disease affect a broad spectrum of mammals including humans worldwide. The economic impact of the disease interestingly requires updated gathering information on the prevalence in slaughtered animals. Accordingly, in the current study, 573 camels, 4300 sheep, and 1235 pigs were surveyed in four Egyptian municipal abattoirs. Among those, 62 (10.82%) camels, 33 (0.77%) sheep and 3 (0.24%) pigs had cystic echinococcosis in lungs, livers and spleen. The diversity of cysts revealed that positive-cystic echinococcosis animals from all species were detected in El-Basatin abattoir. In El-Monieb abattoir, sheep only were infected. In El-Waraa and Beni-Suef abattoirs, cysts were seen in camels only. Infected animals included both sexes. In camels, lungs were the most affected organs, while in sheep, livers were the most abundant. In pigs, hydatid cysts were detected only in lungs. Moreover, camel cysts were mostly large-sized (diameter  >  10 cm) with smaller cysts are also recorded. In sheep, small-, moderately- and large-sized cysts were equally present. Cysts in pigs were large-sized. Camels showed a higher percentage of fertile cysts (46.77%; 29/62) followed by sheep (21.21%; 7/33). Calcified/degenerated cysts were less in cam els (38.71%; 24/62) than in sheep (75.76%). Non-viable cysts were the less frequent in both species (14.52% in camels and 3.03% in sheep). All cysts recovered from pigs wer...

ConclusionHydatid cyst is one of the differential diagnoses of any cystic lesion in patients from an endemic areas of hydatid disease. Hydatid cysts of the female pelvic organs may be diagnosed initially as ovarian cyst, ovarian tumor, or pelvic infection. Most of the cases are diagnosed during surgery which is the main treatment modality; anthelminthic medications may help to decrease the recurrence rate.

This study presents data from the Kazakhstan Scientific and Practical Center for Sanitary and Epidemiological Evaluation and Monitoring on CE patients treated surgically, with a diagnosis confirmed by pathology. Evaluation of data from 2007 to 2016 indicated that the CE incidence rate decreased during this time period in most areas of Kazakhstan (country-level incidence rate of 5.6 versus 4.7 cases/100,000 population in 2007 and 2016, respectively). Cystic echinococcosis had a higher incidence in southern Kazakhstan, with an incidence rate between 7.0 and 10.5 cases per 100,000 population, whereas northern regions had rate...

Abstract Echinococcosis is a serious zoonotic parasitic disease that could be fatal without diagnosis and treatment in a timely manner. Herein, we present a rapid and label-free method for screening of echinococcosis using surface-enhanced Raman spectroscopy (SERS). Three groups of serum SERS spectra based on porous silicon/silver composites are obtained: one group from healthy volunteers (normal, n = 163) and two other groups from patients with pathologically confirmed echinococcosis (cystic echinococcosis (CE), n = 69 and alveolar echinococcosis (AE), n = 38). The derived characteristic spectrum was analyzed to ...

Authors: Wang W, Zhou X, Cui F, Shi C, Wang Y, Men Y, Zhao W, Zhao J Abstract Cystic echinococcosis (CE), a zoonotic disease caused by Echinococcus granulosus at the larval stage, predominantly develops in the liver and lungs of intermediate hosts and eventually results in organ malfunction or even death. The interaction between E. granulosus and human body is incompletely understood. Exosomes are nanosized particles ubiquitously present in human body fluids. Exosomes carry biomolecules that facilitate communication between cells. To the best of our knowledge, the role of exosomes in patients with CE is not reporte...

Abstract Cystic echinococcosis is a chronic and complex zoonotic disease. The mechanisms underlying the parasite's establishment, growth and persistence are not completely understood, and are thought be modulated by a crosstalk through extracellular vesicles (EVs). Here, EVs were isolated from the hydatid cyst fluid (HCF) of patients with cystic echinococcosis and protoscolex culture supernatant (PCS). Proteomic analysis of these EVs revealed several parasite- and human-derived proteins. Very few studies have performed proteomic analysis of EVs isolated from HCF and PCS. Our proteomic analysis of the EVs derived f...

Conclusion: The serological methods used in the study were found to be important in the early diagnosis of alveolar echinococcosis in the endemic areas, since it could be used in sero-epidemiological studies. PMID: 31591872 [PubMed - in process]

Abstract Detailed post mortem analyses of 68 free-ranging, slaughter-age pigs from two sites in the Banke District of Nepal identified 36% as being infected with Echinococcus granulosus. The cysts ranged from infertile, immature cysts a few millimetres in diameter to fertile cysts>10 centimetres in diameter. PCR RFLP and DNA sequencing identified the cysts as being E. granulosus sensu stricto. The Banke district has recently been identified as having a high prevalence of porcine cysticercosis. These data suggest that cestode zoonoses in this, and possibly other parts of Nepal may be a serious concern for human ...
