“…In the present study, the average size in diameter was 1.98 cm for coenurus cerebralis cysts and 1.75 cm for cysticercus tenuicollis cysts. Coenurus cerebralis cysts are considered to be typically 2–5 cm in diameter, and occasionally exceed 10 cm [ 13 ]. In a necroscopy, two cysts (49 and 23 cm 3 ) were found in the brain of a bull in Italy [ 28 ].…”

“…Coenurosis and abdominal cysticercosis are usually fatal to livestock and cause huge losses to the economy due to condemnation of infected muscle and offal [ 9 , 21 ]. Human cases of coenurosis mostly result from accidental infections, and this disease has been found in South Africa, Europe, India, the USA, Brazil and Israel [ 13 ]. However, to date, only one human case of abdominal cysticercosis was recorded, which came from a Chinese four-year-old boy suffering from a stomach ache [ 31 ].…”

Genetic characterization of three mitochondrial gene sequences of goat/sheep-derived coenurus cerebralis and cysticercus tenuicollis isolates in Inner Mongolia, China

Taenia multiceps and Taenia hydatigena are widely distributed tapeworms of canids. Due to a lack of genetic information on these two parasites in China, in this study we analyzed six coenurus cerebralis and two cysticercus tenuicollis cysts from goats or sheep in Inner Mongolia, northern China by amplifying three mitochondrial genes (cox1, nad4, and cytb). Two haplotypes were obtained at each locus for either of the two Taenia cestode species, with ten nucleotide sequences being novel. The degrees of genetic variations were 1.18%, 0.61% and 0.52% for coenurus cerebralis, and 0.24%, 0.46% and 0.35% for cysticercus tenuicollis at the cox1, nad4 and cytb loci, respectively. This is the first molecular description of animal-derived metacestodes of T. multiceps and T. hydatigena in Inner Mongolia, China. Novel nucleotide sequences might reflect endemic genetic characterization of the two cestodes. The present data are useful to explore the biological and epidemiological significance of intra-specific variations within both Taenia cestodes.

“…Eggs hatch, lodge into subcutaneous tissue, eyes or brain, and coenuri develop over approximately 90 days. [ 64 ] It is suggested that the larvae enter the eye by way of ciliary arteries or direct inoculation to the conjunctiva. Coenurus can develop in the vitreous humor and may affect retina and choroid.…”

Ocular lesions are frequently associated with different parasitic infections. The classes of infection include protozoa, nematodes, cestodes, and ectoparasites. Ocular parasitic infections can manifest in any part of the eye; the disease manifestations are frequently characterized as either posterior or anterior eye disease. Parasite-induced lesions may be due to damage directly caused by the parasite, indirect pathology caused by toxic products or the immune response initiated by infectious parasitism. This review characterized the parasite-induced lesions in the posterior segment of the eye. Prompt diagnosis and early treatment of these lesions can reduce ocular morbidity. The method of the literature search was conducted on PubMed, Elsevier Scopus database, and Google Scholar with no limitation on the year of publication databases. It was limited to English articles published for ocular lesions in clinical studies and was focused on parasitic infections of the eye.

“…One breast cyst of T. serialis larvae was detected in a 38-year-old Caucasian female. Cysts in human were presented in the CNS, muscles, and subcutaneous tissue (6). Coenurus serialis cysts in human are rare and only about 100 cases (C. multiceps and C. serialis) were recorded until 2008 (7) with the most cases from Africa (8).…”

Coenurus serialis in Northeastern Iran: A Probable Danger to Human

et al. 2018

Background: Coenurosis is a zoonotic disease caused by the larval stage of Taenia multiceps or Taenia serialis species. Objectives: The current study aimed at reporting the entity of Coenurus serialis in Iran. Methods: The five dead rabbits found in Sarakhs city, Northeastern Iran, were inspection carefully. Coenurus serialis cysts recovered from their muscles were inoculated orally into a four-month-old Spitz/Terrier dog. Results: Based on the current study, 40% of the inspected rabbits in Northeastern Iran had C. serialis. The eggs appeared in the feces 58 days post-inoculation (dpi). Cestodes length was 15-25 cm and the total number of scolex hooks was 30 ± 1. The mean length of large and small hooks was 140 and 90 µm, respectively. Discussion: Taenia multiceps and T. serialis in dogs were morphologically indistinguishable in the current study. The disease exists in Northeastern Iran in animals and is the potential danger as a zoonotic disease. The current study established the first experimental infection of C. serialis in Iran. Neurosurgeons should consider the probability of the disease in this region.
