“…It was reported that experimental infection in carnivores is critical. It is thought that they were best differentiated by transmission to dogs whereby the adult stages can be identified (15). Sheep and rabbits are T. multiceps and T. serialis intermediate hosts, respectively, while C. serialis is not recorded in sheep yet (16).…”

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.

“…There have been several reports from Asia of non-cerebral coenurosis in small ruminants, such as in Iran [ 29 , 31 , 82 ], India [ 27 , 79 , 83 – 85 ], Bangladesh [ 86 ] and Pakistan [ 60 , 87 ]. Outside of Asia, non-cerebral coenurosis has been reported in goats in Oman [ 88 ], Sudan [ 89 ], Namibia [ 90 ], Mozambique [ 71 , 91 ], and in sheep (0.008%) and goats (0.3–1.75%) in the United Arab Emirates [ 26 , 92 , 93 ], where previously 16% prevalence was reported in goats [ 28 ].…”

Taenia multiceps coenurosis: a review

et al. 2022

View full text Add to dashboard Cite

Taenia multiceps is a taeniid cestode that inhabits the small intestines of both wild and domestic carnivores. The larval stage, Coenurus cerebralis, is typically found in the central nervous system (CNS) of a wide range of livestock and, to a lesser extent, in the extra-cerebral tissues of sheep and goats. This review covers all aspects of the life cycle of T. multiceps and its epidemiology, molecular characterization, pathogenesis, diagnosis, therapy, control and zoonotic potential. Coenurosis caused by the larval stage of T. multiceps has a worldwide distribution and is often fatal in intermediate hosts, which can result in substantial economic losses in livestock farming. Molecular characterization using the mitochondrial genes cytochrome c oxidase subunit 1 and nicotinamide adenine dinucleotide dehydrogenase subunit 1 of different T. multiceps populations has revealed significant genetic variation and the presence of three major haplotypes. The disease mostly affects young sheep and is referred to as either acute or chronic coenurosis. Acute coenurosis occurs as a result of oncospheres migrating through the CNS, while chronic coenurosis occurs as a consequence of the coenurus maturing, which causes displacement and pressure atrophy of brain tissue. Non-cerebral coenurosis has been most commonly reported in goats. The best diagnostic method for cerebral coenurosis involves the interpretation of clinical signs with accurate localization of the cyst using diagnostic imaging techniques. A vaccine based on recombinant oncosphere antigens has proved to be an effective tool against T. multiceps infection in sheep. Additionally, use of anthelmintics during the parasite’s migration stages reduces the development of cysts in the sheep brain. Surgery is considered the most effective method for the treatment of cerebral coenurosis in small ruminants, but is often not carried out because of the limited finances of many sheep and goat breeders. However, coenurosis can also be controlled effectively through preventative measures, such as anthelmintic treatment of dogs and the proper disposal of intermediate host carcasses. The parasite is also zoonotic, and cases of coenurosis have been reported in humans with coenuri located in the brain, spinal cord and eyes. Graphical abstract

“…The severity of the disease depends on the location and the space occupied by the cyst, and the associated neuropathological lesions (ACHENEF et al, 1999;SHIVASHARANAPPA et al, 2017). Whereas non-cerebral coenurosis, caused by Taenia giageri, is frequently reported in musculature of sheep and goats (CHRISTODOULOPOULOS et al, 2013(CHRISTODOULOPOULOS et al, , 2015EL SINNARY et al, 1999;SAMI et al, 2014;SCHUSTER et al, 2010).…”

This study documented the first outbreak of cerebral coenurosis in goats in Salalah, southern Oman. Deaths of 130 (16.6%) adult native goats in a herd (n=780) were reported from January to June 2017. Affected goats showed various nervous signs ended by death. Investigations for thiamine deficiency, polioencephalomalacia, caprine arthritis encephalitis, and listeriosis were negative. Upon necropsy, multiple (1-4) thin-walled cysts 2-3.5 cm in diameter containing clear fluid with numerous clusters of protoscolices in the cerebrum and cerebellum had replaced the brain parenchyma, causing space-occupying lesions. Parasitologically, the recovered cysts were Coenurus cerebralis, based on the arrangement of protoscolices, and the number and size of their hooks. Morphologically, each protoscolex had four suckers and a rostellum with double-crown hooks. The large and small hooks were 157.7±0.5 µm and 115±0.6 µm in length, respectively. Histopathologically, the parasite destroyed the affected tissues associated with multifocal to diffuse lymphocytic, non-suppurative meningoencephalitis; ischemic neuronal necrosis; and malacia. This is the first report of cerebral coenurosis in livestock in Oman, which should alert the local public health authorities for the application of prevention and control measures.
