Paramphistomum sukumum sp.nov. and other stomach-flukes from cattle in the Sukumaland area of the Lake Region, Tanganyika

Abstract

The morphology of Paramphistomum sukumum sp.nov. from Bos indicus in the Lake Region of Tanganyika, East Africa, is described and illustrated.A list is given showing the incidence of nine species of the family Paramphistomatidae and three species of the family Gastrothylacidae found in cattle in the Sukumaland area of the Lake Region of Tanganyika.

Paramphistomes in Matebeleland South Province Zimbabwe and their effect on aspects of blood plasma composition in infected cattle.

“…The percentage of infected cattle from each area is shown in Table 2. Five paramphistome species were identified using keys previously established (7,22,23). These were Calicophoron microbothrium, Calicophoron clavula, Calicophoron calicophorum, Calicophoron raja and Gigantocotyle symmeri infecting 20 %, 2 %, 5%, 2 % and 2% of cattle examined respectively.…”

“…Some parmphistome specimens were flattened dorsoventrally between microscope slides held by rubber bands to facilitate examining diagnostic features like vitelline glands, positioning of testes, esophagus, nature of caeca and uterus. Some were preserved in formol saline or 70% ethanol for median sagittal sectioning in order to determine species using the keys previously established (7,22,23). The prevalence and degree of infection with parasites were recorded.…”

“…Calicophoron raja was recovered from Connochaeters taurinus while Paramphistomum microbothrium (Syn.Calicophoron microbothrium Eduardo 1983) was recovered from Aepyceros melampus, Kobus leche and Taurotragus oryx in Zimbabwe (7). These animals share the same niche with cattle and are susceptible to many parasitic diseases found in cattle (6,8,9).…”

“…P. microbothrium was also recovered from cattle in Mashonaland (9). The distribution of paramphistomes is worldwide (7,9,10,11,12,13). Adult parasites are not normally associated with clinical disease, however, occasional outbreaks of parasite gastroenteritis in susceptible livestock is associated with migration of immature parasites through the upper small intestine.…”

Cotylophoron macrosphinctris sp. n. (Trematoda : Paramphistomata) from the African buffalo, Bubalus (Syncerus) caffer Sparrman

“…1) slightly ben ded to ventral surface; length 5,5-7,2 (6,3), greatest breadth at level of acetabulum 1,5-2,5 (1,9), dorsoventral dimension 2,5-3,0 (2,8). The pharynx is located terminal ly; length 0,8-1,1 (0,9), breadth 0,5-1,0 (0,8), Calicophoron (Dinnik, 1964) type. Oesophagus oblique "J" shaped, dorso-ventral position ; length 1,2-1,5 (1,3), grea test breadth 0,3-0,5 (0,4); poste rior two-thirds of its length usual ly provided with a gradual pro cess of muscular thickening ( fig.…”
