A topical antibiotic eye ointment should be applied twice daily. Fresh palatable foods and clean water must always be available. Supportive therapy such as propylene glycol should be given to help prevent development of a severe energy deficit and the possibility of pregnancy toxaemia. The overall recovery rate in sheep can be up to 30 per cent when sheep are treated early enough.įig 7: Sheep recovering from listeriosis. High doses of antibiotic are required to achieve appropriate concentrations within brain tissue to kill the bacteria. Recovery of sheep from listeriosis depends on early detection of illness, together with prompt and aggressive antibiotic treatment prescribed by the vet. Listeriosis can be confirmed as the cause of death in sheep by examination of the brain Treatment Gid (coenurosis, tapeworm cyst in the brain)ĭiagnosis of listeriosis is based on veterinary examination of the live animal.Twin lamb disease (Pregnancy toxaemia) in heavily pregnant ewes during the last four weeks of pregnancy.The following diseases can cause some similar signs: There is a drooping ear, deviated muzzle, flaccid lip and lowered eyelid on the affected side.įig 4: Drooping ear, deviated muzzle, flaccid lip on the affected left side of this sheep.įig 6: Sheep may lean against objects. There is profuse, almost continuous drooling with food material impacted in the cheek of the affected side. Initially, affected animals do not eat or fail to come to the feed trough, are depressed, disorientated and may propel themselves into corners and fences, or under gates and feed troughs.įig 1: Initially, affected animals are depressed and disorientated.įig 2: This sheep propelled itself into the corner of the fence - it is not stuck.įig 3: Affected sheep may propel themselves into corners, into fences, or under gates and feed troughsĪffected sheep may lean against objects due to weakness affecting one side of the body, with knuckling of the foreleg. The incidence of coenurosis was 14.4% in males and 15.9% in females.The infection is limited to one side of the brain in most animals hence the one-sided appearance of nerve paralysis. The number of coenurus cysts in morkaraman sheep was higher (15.9%) than that of akkaraman sheep (14.1%). The infection rates according to the age of animals were 15.0% in one-year-old, 21.7% in two-year-old, and 11.4% in 3-year-old or older animals. The disease, according to the season, was more prevalent in October (28.5%) and less prevalent in April (3.1%). The infected heads contained 1-4 coenurus cysts. The cysts were located in the cerebral hemispheres in 96.7% of the cases and in 3.3% in the cerebellum. Clinical symptoms of coenurosis were seen in only 17 of the animals (4.3%). The infection rate of coenurosis was recorded at 15.5% (60/387) in the examined heads. During the study, the breed, age, sex of animals, the location of cysts, numbers, diameters of the cysts, the amount of the fluid, and number of the scolices were recorded. The prevalence of Coenurus cerebralis was investigated for 12 months in 387 slaughtered sheep in the Kars province. Clustering pattern of the phylo-genetic tree showed no effect for the geographic location or the host species. Phylogenetic analysis based on COI and ND1 gene sequences indicated that the generated sequences in the present study and the reference sequences in the database clustered in 4 haplogroups, with more or less similar topologies. On contrast to the nuclear gene marker, considerably low genetic diversity was seen in the analyzed mitochondrial gene markers. Molecular analysis of representative samples of coenuri at ITS1 gene marker showed extensive intra-and inter-sequence diversity due to deletions/insertions in the microsatellite regions. cerebralis cysts in the brain of 111 out of 420 (26.4%), with overall infection rate 3.03% of the involved sheep population. Postmortem examination of these animals after slaughter at local abattoirs indicated to occurrence of C. Out of 3668 animals distributed in 50 herds at localities of Ashmoun and El Sadat cities, El Menoufia Province, Egypt, 420 (11.45%) sheep showed neurological disorders. Species identification and genetic diversity were analyzed based on PCR-sequence analysis of nuclear ITS1 and mitochondrial cytochrome oxidase (COI) and nicotinamide adenine dinucleotide dehydrogenase (ND1) gene markers. Infection rate was determined by postmortem inspection of heads of the cases that showed neurological manifestations. The present study aimed to determine the occurrence and molecular identity of C. cerebralis particularly infects sheep and goats, and pose a public health concerns. Coenurosis is a parasitic disease caused by the larval stage (Coenurus cerebralis) of the canids cestode Taenia multiceps.
