Parasites of South African wildlife. XI. Description of a new race of Cooperia rotundispiculum Gibbons and Khalil, 1980

During surveys of the helminths of South African wildlife, a Cooperia sp. that closely resembles Cooperia rotundispiculum Gibbons & Khalil, 1980, was recovered from several antelope species. This nematode has spicules 0,140-0,248mm long and has 18-20 longitudinal cuticular ridges, whereas typical C. rotundispiculum has spicules 0,179-226 mm long and has 14 ridges. In view of the few differences between the 2 helminths, the Cooperia sp. is described here as a race of C. rotundispiculum.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

Some helminth and arthropod parasites of the grey duiker, Sylvicapra grimmia

Sixteen grey duikers were culled on the farm Riekert's Laager in the central Transvaal at irregular intervals from May 1979 - March 1981. One trematode species, 3 cestode species and 16 nematode species were recovered from these animals. Of these the following are new helminth records for this antelope: Cooperia hungi, Cooperia neitzi, Cooperia pectinata, Trichostrongylus axei, Trichostrongylus colubriformis, Trichostrongylus falculatus, Trichostrongylus instabilis, Impalaia tuberculata, Nematodirus sp. and Paramphistomum sp. In addition, 6 species of ixodid ticks were collected. These, in order of abundance, were Amblyomma hebraeum (55,9%), Rhipicephalus appendiculatus (36,6%), Rhipicephalus evertsi evertsi (5,1%), Boophilus decoloratus (2,3% ), Boophilus microplus (0,05%) and Haemaphysalis sp. (0,05%). Only 60 (2,8%) of the 2 118 ticks that were collected were adults. Of the 3 species of lice that were recovered, Linognathus zumpti zumpti was most abundant (58,9%), but, out of a total of 1 498 collected, 1 496 occurred on 1 animal only. Linognathus breviceps constituted 29,5% and Damalinia lerouxi 11,6% of the total. A total of 277 specimens of the hippoboscid fly Lipoptena paradoxa were collected from 12 of the 16 animals examined. Trends in the seasonal fluctuation of Haemonchus, Trichostrongylus, Impalaia, Lipoptena and the immature stages of Amblyomma and R. appendiculatus are graphically illustrated.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

The haemocytology and histology of the haemopoietic organs of South African freshwater fish. III. The leucocytes, plasma cells and macrophages of Clarias gariepinus and Sarotherodon mossambicus

The various leucocytes, plasma cells and macrophages are described and illustrated. Eosinophils and basophils are lacking in Clarias gariepinus but present in Sarotherodon mossambicus. The leucocytes of C. gariepinus resemble those found in mammals, as do the plasma cells and macrophages of both species. A possible mechanism for their formation is postulated.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

Feed selection and water intake of indigenous goat wethers under stall-feeding conditions

Six indigenous (Pedi) goat wethers (18 months old) with an average body mass of 25.1 kg were fed five diets, consisting of a mixture of lucerne (Medicago sativa) and teff (Eragrostis teff) in a cafeteria style arrangement (Trial 1). The diets were formulated to be iso-caloric with crude protein (CP) levels of 7, 9, 11, 13 and 15%. In Trial 2, the 15% CP diet was excluded. Intake of DM was highest on the highest CP diet and declined rapidly on the diets where the CP content was lower. Water was available ad lib. leading to an average daily water intake of 1.4 ± 0.4 litres in both trials. It was concluded that goats have the ability to select for a higher protein diet and can utilise less water than sheep.Ses inheemse (Pedi) bokkapaters (ouderdom 18 maande) met 'n gemiddelde liggaamsmassa van 25.1 kg is vyf diete in 'n kafeteria-stelsel aangebied. 'n Mengsel van lusern (Medicago sativa) en tef (Eragrostis teff) is voorberei om isokalories te wees met ruproteieninhoude (RP) van 7, 9, 11, 13 en 15% (Proef 1). Die 15% RP-dieet is tydens die tweede proef weggelaat. Die DM-inname was die hoogste op die hoogste RP-dieet en het verminder met 'n daling in RP-inhoud. Water was ad lib. beskikbaar en het gelei tot 'n gemiddelde daaglikse waterinname van 1.4 ± 0.4 liter vir beide proewe. Die gevolgtrekking is dat die bokke die potensiaal besit om 'n hoer proteien dieet te kan selekteer en minder water as skape te gebruik.https://www.sasas.co.za/resources/sa-journal-animal-sciencehj2020Anatomy and Physiolog

A revision of the genus Impalaia Mönnig, 1924

A revision of the genus lmpalaia Monnig, 1924 forms the subject of this report. Besides the type species, lmpalaia tuberculata Monnig, 1924, there are 2 valid species, viz., I. nudicollis Monnig, 1931and I. okapiae (Van den Berghe, 1937). I. tuberculata longispiculata (Wetzel & Fortmeyer, 1960), I. somaliensis (Crovieri, 1929) and I. aegyptiaca Soliman, 1956 are synonymous with I. tuberculata. I. taurotragi (LeRoux, 1936) appears to be an aberrant form of/. nudicollis. A parasite/host checklist is included.The articles have been scanned in colour with a HP Scanjet 5590; 300dpi.

Paracooperia horaki n.sp. (Nematoda: Trichostrongylidae) from the nyala Tragelaphus angasi Gray, 1849.

A new species of Paracooperia Travassos, 1935 was found in small numbers in the small intestines of 36 out of 68 nyala Tragelaphus angasi Gray 1849 in the Mkuzi, Ndumu and Umfolozi Game Reserves, Natal. The worms, for which the name Paracooperia horaki is proposed, can be differentiated from the closely related Paracooperia devossi Boomker & Kingsley, 1984 by the absence of ridges on 1 of the branches of the spicules, the slightly longer branches of the tips of the dorsal ray and the large hemispheric knobs on the ends of the spicules. Furthermore, the branch of the spicules that bears the hook-like process is about two thirds the length of the spicule in P. devossi and almost the entire length of the spicule in P. horaki. The ovigerous females of P. horaki have 2 or 3 expanded ridges in front of the vulva that form vulvar flaps. The females without eggs resemble those of P. devossi and have only a single vulvar flap.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

Parasites of South African freshwater fish. II. Redescription of the African species of the genus Phyllodistomum Braun, 1899 (Trematoda: Gorgoderinae) and the description of a new species

During 1980 a survey of the parasites of freshwater fish was conducted in the Sabie and Crocodile Rivers in the southern part of the Kruger National Park, Transvaal. A new species of Phyllodistomum, Braun, 1899, for which the name Phyllodistomum bavuri is proposed, was found in the urinary bladder of many of the catfish, Clarias gariepinus (Burchell, 1822), examined. The new species resembles Phyllodistomum linguale Odhner, 1902 and Phyllodistomum vanderwaali Prudhoe & Hussey, 1977, but may be differentiated from the former species in that the ovary and the vitellaria are smooth, while those of P. linguale are irregularly lobed. The ovary of P. vanderwaali is irregularly lobed while that of P. bavuri never has more than 3 indistinct lobes. In addition, P. bavuri is much larger than P. vanderwaali. P. bavuri is readily differentiated from the other 4 African species of Phyllodistomum, namely, Phyllodistomum spatula (Odhner, 1902), Phyllodistomum spatulaeforme (Odhner, 1902), Phyllodistomum ghanense Thomas, 1958 and Phyllodistomum symmetrorchis Thomas, 1958. For comparative purposes the African species are briefly redescribed and illustrated. P. bavuri occurred throughout the year and their numbers do not appear to fluctuate seasonally in the Kruger National Park.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.
