The recent transfer of Elthusa parva (Richardson, 1910) from Ceratothoa created a homonymy with Elthusa parva (Nierstrasz, 1915). Elthusa parva (Richardson, 1910) has priority and Elthusa nierstraszinom. n. is proposed as the new replacement name for the junior secondary homonym Elthusa parva (Nierstrasz, 1915).

To study the new antifungal active triterpene glycosides of sea cucumber Holothuria scabra. Triterpene glycosides from Holothuria scabra were separated and purified by silica gel chromatography, reversed-phase silica gel chromatography and RP-HPLC. Their structures were elucidated on the basis of spectral data and chemical evidence. Three triterpene glycosides were identified as scabraside A (1...

Biotic resistance is the process where aspects of the receiving environment inhibit the establishment and invasion of an introduced species. Resistance against an introduced fish can be through strong competition and/or predation from resident fishes. Here, the biotic resistance against introduced topmouth gudgeon Pseudorasbora parva (a highly invasive fish in Europe) by resident carp Cyprinus ...

Experimental transmissions of cloned Theileria parva in cattle with Rhipicephalus appendiculatus ticks were compared to transmissions with uncloned T. parva during studies on the potential for genetic recombination during syngamy of Theileria to produce antigenic diversity for evasion of bovine immunity. Prevalence and abundance of T. parva infection in adult ticks, which resulted from the feed...

This paper reports on some sea cucumbers (Holothuroidea) in the collections of the NHMUK, taken off the coast of Ghana. Most result from collections around Accra during the years 1949-52. A couple of other species are included. Altogether six species are here reported, viz. Holothuria (Holothuria) dakarensis Panning, 1939; Holothuria (Semperothuria) imitans Ludwig, 1875; Holothuria (Vaneyothuri...

East Coast fever caused by Theileria parva parva has been eradicated from South Africa, but tick-borne infections with other species of Theileria still occur, particularly in cattle and African buffalo (Syncerus caffer). One such infection is Corridor disease caused by T. parva lawrencei, which is controlled by restricting the movement of African buffalo. Other species reviewed are T. parva bov...

East coast fever is a disease of cattle caused by Theileria parva and is transmitted by the tick Rhipicephalus appendiculatus. Buffalos are a natural reservoir of the parasite. The objectives of this study were to determine the T. parva infection in buffalo and cattle field samples, to identify genotypes of T. parva infecting cattle and buffalo and finally to investigate the presence of buffalo...
