Cystic echinococcosis has been considered one of the major parasitic zoonoses which is associated with severe economic losses. The present study was undertaken to investigate the occurrence, organ distribution, cyst fertility, and viability of cystic echinococcosis in slaughtered camels and cattle from various abattoirs in Assiut Governorate, Egypt. The work also involved morphological, morphometric, and molecular identification of the parasite. The occurrence of hydatid cysts was investigated in total number of 100 lungs of camels and 574 liver and lungs of cattle admitted to three slaughterhouses at Assiut Governorate, Egypt. Moreover, several individual variable factors, including organ involvement, age, sex, and hydatid cyst characteristics, were studied to identify their possible association with the occurrence of the disease. Genomic DNA was extracted from the hydatid cysts, followed by molecular identification of the parasite through amplification of ribosomal DNA internal transcribed spacer (ITS) regions. Hydatid cysts were found in 6 camels (6%) out of 100 inspected camels, while 5 hydatid cysts (0.87%) were detected in a total number of 574 cattle examined. The parasite was detected exclusively in lungs of camels, while lungs were the main organ infected by the parasite in cattle and one hydatid cyst was found in the liver (0.17%). In camel, 66.7, 16.65, and 16.65%of detected cysts were fertile, sterile, and calcified, respectively, while in cattle, these percentages were 60, 20, and 20%, respectively. None of the studied variable factors were significantly associated with the occurrence of the disease in camels, with the exception that all cysts were found in the lung. Conversely, we found a significant association (P < 0.05) between the age and sex of the slaughtered cattle and the occurrence of hydatid cysts. In this respect, the rate of infection was higher in female cattle and those cattle more than 5 years (P < 0.05). The morphological, morphometric, and molecular studies confirmed the presence of the parasite. Taken together, our results concluded that camels and cattle play a potential role in maintaining the transmission cycle of this zoonotic parasite.

Background: Cystic echinococcosis, a major public health and economic concern, is a zoonotic helminth infection with worldwide distribution. This study was conducted to investigate the genetic characteristics of hydatid cysts isolated from human and livestock in Hamadan region, western Iran during 2016-2017. Methods: Ten human hydatid cysts and 40 animal hydatid cysts including 32 sheep, 5 cattle and 3 goats were genotyped by PCR amplification of two mitochondrial genes, cox1 and nad1. Genetic identification of the isolates was performed by using bioinformatics software and mtDNA nucleotide sequences of the parasite, available in GenBank database. Results: The PCR amplification was successfully carried out on 50 hydatid cyst isolates and then the nucleotide sequencing was conducted. The sequence analysis of the samples found that the isolates belonged to E. granulosus sensu stricto including G1 (42/50, 84%), G2 (4/50, 8%) and G3 (4/50, 8%) genotype. The G1 genotype was detected in human (8/10, 80%), sheep (26/32, 81%), cattle (5/5, 100%) and goat (3/3, 100%) hydatid cysts. The G2 and G3 genotypes were found only in sheep and human isolates. Alignment analysis of the cox1 and nad1 gene sequences revealed thirteen and ten sequence types, respectively. Conclusion: G1 was the prevailing genotype of E. granulosus in the area and dog-sheep transmission cycle should be considered when implementing hydatidosis control programs. In addition, high genetic diversity was detected among the hydatid cyst isolates.

Adventitial Layer

Cystic echinococcosis is a worldwide zoonosis caused by the cestode Echinococcus granulosus. Two types of hydatid cysts occur in intermediate hosts: fertile cysts that generate protoscoleces from the germinal layer of the cyst, and infertile cysts that do not produce protoscoleces and are unable to continue the life cycle of the parasite. The adventitial layer, a host-derived fibrous capsule surrounding the hydatid cyst, is suggested to play an important role in local immune regulation during infection and in fertility of the cysts. Fasciola hepatica, another important parasite of cattle, induces a characteristic Th2-like immune response that could modulate the immune response against E. granulosus. Natural co-infection of both parasites is common in cattle, but no reports describe the local immune response against E. granulosus with F. hepatica infection in the same host. This study analyzed the number and distribution of T and B cells in the adventitial layer of liver and lung cysts and the relationship with cyst fertility and F. hepatica co-infection. T lymphocytes were the predominant cell type in the adventitial layer of infertile hydatid cysts and were more numerous in infertile hydatid cysts. B lymphocyte numbers were not associated with hydatid cyst fertility. Mast cells were infrequent in the adventitial layer. The number of T and B cells was not associated with F. hepatica co-infection. The present study contributes to the understanding of local immune responses in bovine cystic echinococcosis.

AbstractFew molecular studies have identified the current status of cystic echinococcosis in Egypt. The present study aimed to ascertain the genotype(s) of Echinococcus granulosus responsible for human hydatidosis in different Egyptian governorates (regions). Animal isolates were collected from 40 camels, 5 pigs and 44 sheep. 27 human isolates were included in the present study. Specific PCR was performed and followed by DNA sequencing for mitochondrial 12S ribosomal RNA gene and BLAST analysis.The sheep cysts were not hydatid cysts. G6 genotype (camel starin) predominates in human, camel and pig isolates. G7 genotype (pig strain) was detected in two human isolates and one pig isolate. G1 genotype (sheep strain) was detected in one human isolate from Yemen and in no animal isolates. This is the first record of G7 in Egypt and G1 in Yemen.

Cystic echinococcosis (CE) is of increasing public health and socio-economic concern because of the large morbidity rates and produced high economic losses in the livestock industry. The objective of the current research was to study the reliability of indirect ELISA in detecting CE, based on two dif-ferent types of crude antigens of camel origin; protoscolex and germinal layer antigens from hydatid cyst. Blood samples were collected from 284 (125 slaughtered and 159 live camels). Out of 125 slaughtered camels examined visually, 55 (44%) were found to have hydatid cysts. Of them, 52/125 (41.6%) and 3/125 (2.4%) harboured hydatid cysts in lungs and livers respectively. Fertile lung cysts were 32.8%; 26.9% were sterile, while 40.3% of lung and liver cysts were calcified. The sensitivity of ELISA was 83% and 46.5% when protoscolex and germinal layer antigens were used, respectively. The respective specificity of antigens of protoscolex and germinal layer was 70.3% and 41.7%. The protoscolex antigen showed higher accuracy (73.6%) compared to the germinal layer antigen (52.8%). The cross reactivity of these antigens were evaluated with antigens and hyperimmune sera of CE and Fasciola spp. and Haemonchus contortus using ELISA. The results showed also weak immunogenic potency of each antigen with Fasciola spp. hyperimmune sera at dilution 1:50 while hyperimmune sera of Haemonchus contortus did not bind any antigen.

Epidemiological Situation

The purpose of this article was to present current data on cases of cystic echinococcosis in humans and animals in Poland. Cystic echinococcosis, caused by Echinococcus granulosus, is one of the most important parasitic zoonoses occurring globally. In many regions of the world, the disease is an important epidemiological problem. The life cycle of Echinococcus involves hoofed farm animals and dogs. Among its species and genotypes ascertained in the world, two (G1 and G7) have been confirmed in sheep and pigs as intermediate hosts in Poland. Molecular examinations of postoperative parasitic material from patients established that the porcine strain G7 is the cause of human cystic echinococcosis in Poland. Data on post-slaughter examinations of pigs identified as intermediate hosts of E. granu-losus suggest that the number of cases reported in humans (approx. 40 annually) is probably underestimated. In the last two years, the prevalence of hydatid cysts in pigs in Poland has been estimated at 0.3%, with the highest number of infected animals in central Poland (0.4%-1.2%). This indicates the presence of infection in dogs and the risk of echinococcosis for humans.

Background. Most cases of hydatid cysts form in the liver and lung and other tissues are considered as unusual locations in hydatid cysts. The current study aimed to find out the rate and features of hydatid cysts in uncommon locations in Fars Province, Southern Iran, over a 15-year period. Methods. The hospital records of patients who underwent surgery for hydatid cysts in university-affiliated hospitals in Fars Province, Southern Iran, from 2004 to 2018, were retrospectively reviewed. For each patient, clinical and demographical data were recorded. Results. During a 15-year period, a total of 501 patients were surgically treated for hydatid cysts, and out of these, 46 (9.2%) were presented with the unusual locations of hydatid disease. Males constituted 28 (60.9%) of these patients while 18 (39.1%) of the patients were females. The patients’ age ranged from 5 to 80 years (mean = 40.49; SD = 20.37). The size of the cysts ranged from 2 to 20 cm (mean = 8.69, SD = 4.59). The most common unusual location for the hydatid cyst was the spleen with 30.4% of cases, followed by the pelvic cavity (15.2%). Out of 46 cases with unusual location of the hydatid cyst, 10 (21.7%) cases had lung, 22 (47.8%) cases had liver, and 5 (10.9%) cases had both liver and lung hydatid cysts, simultaneously with cysts in unusual locations. Conclusion. In cystic echinococcosis- (CE) endemic areas, hydatid disease can affect any organ, from head to toe, in humans. The disease should be considered in the differential diagnosis of any cystic entities anywhere in the body.

Abstract Background Hydatid cysts are parasitic zoonoses that often occur in the liver. Pancreatic hydatid cysts are very rare and are usually misdiagnosed as pancreatic cystadenomas. At present, surgical resection combined with albendazole administration is the standard treatment for pancreatic hydatid cysts. However, making accurate preoperative diagnoses and avoiding intraoperative cystic rupture are challenges for surgeons. Case presentation A 28-year-old woman from the pastoral area presented to the surgical office complaining of abdominal pain and new-onset jaundice that began 9 days earlier. An enhanced computed tomography scan demonstrated a 6.0 × 5.3 cm pancreatic head cystic mass that compressed the common bile duct and induced choledochectasia. The preoperative diagnosis was pancreatic head cystadenoma, and laparotomic pancreaticoduodenectomy was initiated successfully. The intra- and postoperative diagnosis was pancreatic hydatid cyst. The patient was discharged uneventfully 7 days after the operation. A 1-year course of albendazole (15 mg/kg/day) was admitted. Conclusion Pancreatic hydatid cysts are rare and often misdiagnosed as other types of cysts. History of living in an area in which the causative organism is endemic and positive anti-echinococcus IgG antibody status could help with the diagnosis. Radical resection combined with oral albendazole administration is the standard treatment for pancreatic hydatid cysts. Avoiding perioperative cystic rupture and abdominal echinococcosis implantation metastasis is crucial for the success of the operation.

The Status

Cystic echinococcosis (CE) is a significant zoonosis, and is endemic in some parts of the world including Iran. Hydatid cyst in Iran has been studied from different aspects and has been reported from most parts of the country. But there is no comprehensive report on the appearance of pollution in the country. This study was conducted to investigate the approximate status of infection from 1985 to 2019. In this review article, various reports on hydatid cysts were collected from 1985 to 2019. According to three criteria, i.e. the rate of infection of dogs with adult worms, the rate of infection of livestock, and the rate of infection of humans with hydatid cysts, the articles were summarized and presented to approximate the status of infection in Iran. In this study, the average infection among 11593 dogs was estimated to be 11.28%. In the case of livestock, according to this review, the maximum infection of sheep was in Ardebil with 74.4%, goats and cattle were in Sari with 37.8% and 40.1%, camels in Khorasan Razavi with 40.40%, and Tabriz had the highest amount of infection in buffaloes. Out of 70907 people tested, the summary of seroepidemiological studies shows that the average infection in humans is 5.57%. The information obtained from this review article shows that despite the efforts of health organizations and veterinary organizations, the rate of infection in Iran is still high compared to some countries.

AbstractLung hydatidosis can remain latent for a long time, and symptoms may occur when the cysts grow to a certain size or when symptoms arise secondary to complications such as rupture or superinfection with bacterial organisms or fungi. A variety of signs denoting different appearances of complicated and/or uncomplicated pulmonary hydatid cysts have been described on chest radiographs and computed tomography scans. Aspergillosis is one of the most common fungal infections associated with pre-existing pulmonary cavities. The coexistence of aspergillosis and hydatid cyst is rare. Citrobacter infections usually occur in patients with underlying co-morbidities or immunosuppression. We presented a case of pulmonary echinococcosis with multiple bilateral cysts in which several consecutive episodes of cysts rupture and concomitant Aspergillus and Citrobacter pulmonary infections have been documented.
