“…Cystic echinococcosis is one of the most widespread parasitic zoonoses in the Mediterranean region and constitutes a serious public health problem (Battelli et al 2002;Ecca et al 2002). As in other countries of the region (e. g. Katic-Radivojevic and Popovic 1997;Todorov and Boeva 1999;Sotiraki et al 2003;Varcasia et al 2007;Christodoulopoulos et al 2008), prevalence of cystic echinococcosis according to abattoir surveys ranged from 5% to 75% in Albania, with sheep and cattle usually presenting higher rates of infection than goats and swine (Moskvin 1958;Èrhardova et al 1960;Dizdari 1971;Meshi and Veliu 1973;Melonashi 1975;Papajani 1980;Pandeli 1983;Pepa 1986;Zanaj 1997). In a retrospective survey based on surgical cases and autopsy findings, the incidence of human cystic echinococcosis in Albania was estimated as 2.05 per 100,000 inhabitants for the years 1958-1987 (Zanaj and Elezi 1998).…”

From 2004 to 2009, the digestive tracts of 111 dogs from suburban areas around Tirana, Albania, were examined for intestinal helminths. In addition, rectal faecal samples of all dogs were examined for protozoan infections and 48 faecal samples from dogs >6 months of age were processed with the Baermann technique to test for the excretion of lungworm larvae. The heart and pulmonary arteries of 30 dogs >6 months of age also were examined for nematode parasites. The intestinal parasite fauna of the dogs included three protozoan species (Cystoisospora canis, Cystoisospora ohioensis/burrowsi, Sarcocystis spp.), three cestode species (Dipylidium caninum, Taenia hydatigena, Echinococcus granulosus), five nematode species (Ancylostoma caninum, Uncinaria stenocephala, Toxocara canis, Toxascaris leonina, Trichuris vulpis) and one acanthocephalan (Centrorhynchus buteonis). Rates of infection were: 15.3% for C. canis, 31.5% for C. ohioensis/burrowsi, 1.8% for Sarcocystis spp., 65.8% for D. caninum, 16.2% for T. hydatigena, 2.7% for E. granulosus (genotype G1), 13.5% for A. caninum, 64.9% for U. stenocephala, 75.7% for T. canis, 0.9% for T. leonina, 21.6% for T. vulpis and 0.9% for C. buteonis. Up to six species of gastrointestinal parasites were found per dog. The 63 ≤ 6-month-old dogs harboured significantly (p<0.001) fewer gastrointestinal parasite species concurrently (mean 2.65 ± 1.25 species per animal) than the 48 older animals (mean 3.77 ± 1.45 species per animal). Dogs >6 months of age harboured significantly (p<0.05) more D. caninum, T. hydatigena, A. caninum, U. stenocephala and T. vulpis compared to younger dogs. Conversely, the younger dogs harboured significantly (p<0.001) more T. canis than the older ones. There was no difference in the male and female dogs' counts of individual intestinal helminth species apart from T. hydatigena in dogs >6 months of age: Male dogs harboured significantly (p<0.05) more tapeworms than female dogs. Based on faecal examination, there was no indication for lungworm infection; however, two adult heartworms (Dirofilaria immitis) were found in the right ventricle of one dog.

“…Cerebral coenurosis in small ruminants is still present in countries of North Africa, the Middle East and Asia (Sharma and Chauhan 2006) and recent outbreaks have been described in Switzerland (Schweizer et al 2006), Italy (Varcasia et al 2006, Scala et al 2007) and Greece (Christodoulopoulos 2007, Christodoulopoulos et al 2008.…”

Three hundred carcasses of young goats aged between 3 and 6 months were found to be infested with cysts at routine meat inspection at an abattoir in Dubai in 2008. Two types of cestode larvae were situated in the liver, abdominal cavities, under the skin and between the fasciae of the skeletal muscles. Sixty-two typical coenuri loaded with multiple scolices (between 46 and 474) and situated in clusters (between 6 and 17) at the inner membrane of the bladder were recorded in numbers between one and 12 in 30 animals. The volume of coenuri cysts varied between one and 40 ml. The rostellum of 300-400 microm in diameter carried 26 to 32 hooks arranged in two circles. The average length of larger and smaller hooks was 160 and 114 microm, respectively. All other metacestodes were determined as Cysticercus tenuicollis. Although the structure of coenuri and the measurements of scolices were identical with Coenurus cerebralis, the location of these metacestodes outside the central nervous system, suggests that these larvae might belong to a different strain of Multiceps multiceps or even to a closely related species.

“…In high infections, mortality may occurs, as described by Scala et al (2016) in central Sardinia, Italy, where an acute outbreak of T. hydatigena cysticercosis occurred, causing mortality in 5 of 21 (23.8%) female lambs. In Greek slaughtered sheep, the infection level due to C. tenuicollis was 29.4% (CHRISTODOULOPOULOS et al, 2008). The infection levels in small ruminant carcasses in Brazil are high.…”

This study aimed to determine the prevalence and risk factors for C. tenuicollis among goats and sheep in slaughterhouses in Paraíba. 390 animals (195 goats and 195 sheep) in the municipalities of Patos and Esperança, Paraíba, Brazil, were inspected between February and May 2014. The prevalence of C. tenuicollis was 39% (76/195) in goats and 17.4% (34/195) in sheep. In both species, most of the cysticerci vesicles were located at the omentum and mesentery. The only risk factor found was extensive sheep farming. It can be concluded that C. tenuicollis is highly prevalent in small ruminants in Paraíba, being more prevalent in goats than in sheep. Extensively-reared sheep were twice as likely to develop infection by this parasite.Keywords: Goat and sheep farming, cestode, Taenia hydatigena. ResumoObjetivou-se determinar a prevalência e os fatores de riscos de C. tenuicollis em caprinos e ovinos nos matadouros da Paraíba. Foram inspecionados 390 animais (195 caprinos e 195 ovinos) nos municípios de Patos e Esperança, Paraíba, Brasil, no período de Fevereiro a Maio de 2014. A prevalência de C. tenuicollis em caprinos foi de 39% (76/195) e em ovinos de 17,4% (34/195). Os locais mais acometidos por C. tenuicollis nas duas espécies foram o omento e o mesentério. O único fator de risco encontrado foi a produção extensiva de ovinos. Pode-se concluir que é alta a prevalência de C. tenuicollis em pequenos ruminantes no Estado da Paraíba, sendo mais prevalente na espécie caprina; e que ovinos criados de forma extensiva apresentam duas vezes mais riscos de contrais a infecção por este parasita.Palavras-chave: Caprinovinocultura, cestódeo, Taenia hydatigena.
