“…Reports on prevalence and location of various species of Setaria worms in cattle from India and abroad were recorded. S. digitata adult worms found in the urinary bladder (Alwar and Lalitha 1954;Yoshikawa et al 1976; Thirumurthy et al 1995), eye (Otake 1980, Ohtake et al 1989, epicardium of the heart (Fujita et al 1985) and in the lungs and mesenteric lymph nodes (Ashizawa and Moritomo 1989). S. cervi worms observed in patches of inflammatory reaction in the visceral peritoneum (Sarwar 1945;Chauhan and Pande 1980), liver (Vasudev 1955) and spinal cord (Pachauri 1972).…”

Morphological characters of Setaria sp. collected from cattle and buffaloes were studied. Three species Setaria digitata, Setaria cervi and Setaria labiatopapillosa were identified in the present study. Out of the 500 cattle screened 187 were found to harbour worms. 56.8 % (106) of animals with S. digitata, 24.13 % (45) had S. cervi and 18.96 % (36) had S. labiatopapillosa. Morphological characters of male and female worms of all the three species were studied in detail.

“…Therefore, it seems to be important to ascertain which Setaria species caused cerebrospinal setariosis. Appropriate diagnostic techniques can be developed, however, there are no epidemiological surveys of bovine Setaria species in cattle in Japan since the 1970s [6,10].…”

“…When the results for Aomori Prefecture were compared with those for Kumamoto Prefecture, the frequencies of S. marshalli and S. labiatopapillosa in Aomori Prefecture were high. Yoshikawa et al [10] reported that a total of 148 Setaria worms collected from the cattle in Aomori Prefecture in 1976, all worms were identified as S. digitata. This suggests that the frequencies of S. marshalli and S. labiatopapillosa have increased during the past 30 years in Aomori Prefecture.…”

ABSTRACT. An epidemiological survey of bovine Setaria collected from the abdominal cavities was performed morphologically on the cattle in Aomori and Kumamoto Prefectures, Japan, between August 2005 and July 2006. Fifty Setaria worms were collected from the cattle in Aomori Prefecture and 847 from those in Kumamoto Prefecture. Of these worms, 35 were identified as Setaria digitata, 14 as S. marshalli, and one as S. labiatopapillosa in Aomori Prefecture, while 816 were identified as S. digitata and 31 as S. marshalli in Kumamoto Prefecture. KEY WORDS: Aomori Prefecture, bovine Setaria, Kumamoto Prefecture.

“…Heterotopic parasitism, such as S. digitata on the epicardium of the cardiac ventricle [9] and in urinary bladder [20] of cattle resulting in the formation of granuloma had been reported in Japan. Recently, ocular infection by S. digitata in cattle was reported by Ohtake, et al in Japan [10] and Shin, et al in South Korea [13].…”

ABSTRACT. Setaria digitata and S. marshalli larvae were observed in the cerebrospinal cavity of 2 paralyzed cattle in Taiwan. The 2 affected cattle showed quadriplegia and lumbar paralysis, respectively. At necropsy, which was performed 7 days after the 7-mon th-old cattle became quadriplegic, three and nineteen S. marshalli larvae as well as two female adult worms were found in the cranial cavity, spinal cavity and peritoneal cavity of the cattle, respectively. Necropsy on the other 8-month-old cattle was also performed 3 days after it showed lumbar paralysis, and ten S. digitata larvae were found in the spinal cavity. In both cattle, many mononuclear inflammatory cells mixed with a few eosinophils were seen accumulated in the connective tissue around the root of the spinal nerves. Infiltration of eosinophils and mononuclear inflammatory cells into the epidura and arachnoidea of the brain were also observed. The major inflammatory cell was lymphocytes, but neutrophils and eosinophils were also present. The number of cells in the cerebrospinal fluid collected initially from the two affected cattle were 105/0.01 ml and 143/ 0.01 ml, respectively. This is the first report of cerebrospinal setariosis in cattle associated with S. marshalli. KEY WORDS: bovine cerebrospinal setariosis, cerebrospinal fluid, Setaria digitata, Setaria marshalli, Taiwan.J. Vet. Med. Sci. 65(9): 977-983, 2003 Setaria species are filarial parasites that are commonly found in the peritoneal cavity of cattle and other ungulates. The parasites are generally considered to be nonpathogenic in their natural hosts, but transmission of infective larvae through mosquito and other arthropod vectors to non-permissive hosts such as goats, sheep, or horses, can result in serious and often fatal neuropathological disorder commonly referred to as cerebrospinal nematodiasis [1,11]. Moreover, Setaria cervi (Rudolphi, 1819) [2], S. digitata (Linstow, 1906) [18,19], S. labiatopapillosa (Alessandrini, 1848) [3,14], S. marshalli (Boulenger, 1921) [8,16,18,19], and S. leichungwingi (Chen, 1935) [7] had been reported to parasitize in the peritoneal cavity of cattle without producing clinical signs. However, larvae of S. cervi, which normally parasitized in the deer peritoneal and thoracic cavities as adult worms, had been found in the cerebrospinal cavity of deer resulting in lumbar paralysis of the host [6,15,17]. Our literature search showed that no cases of cerebrospinal setariosis with S. marshalli infection in cattle had ever been reported. We report herein the discovery of S. marshalli and S. digitata larvae from the cerebrospinal cavity of 2 paralyzed cattle in Taichung, central Taiwan. Pathological findings and inflammatory cell counts of cerebrospinal fluid (CSF) of the affected cattle are also presented. MATERIALS AND METHODS Case history:In August and September of 2001, a 7-month-old (case 1) and an 8-month-old (case 2) HolsteinFriesian strain cattle were found to have quadriplegia and lumbar paralysis, respectively, in Taichung, central T...
