two new species of ticks from southern africa whose adults parasitize the feet of ungulates: rhipicephalus lounsburyi n. sp. and rhipicephalus neumanni n. sp. (ixodoidea, ixodidae).theiler & robinson (1953) described, as rhipicephalus follis dönitz, 1910, a tick species originating from dordrecht, eastern cape province. a comparison of this tick with the syntypes of r. follis has now shown, though, that these 2 entities are different and it is therefore redescribed below as rhipicephalus lounsburyi n. sp. its adults parasitize sheep and various wild ungulates, attaching primarily on their feet. the hosts of the immature stages are still unknown. it has now been recorded fr ...19902338999
phage types of salmonella enterica serovar enteritidis isolated in south africa from 1991-1995.a total of 615 strains of salmonella enterica serovar enteritidis (se), received from 1991-1995 at the onderstepoort veterinary institute (ovi), were phage typed. most se isolates (54,7%) originated from poultry followed by humans (28,5 %) and poultry eggs (9,6 %). phage type 34 was the most prevalent (40,5 %) of all isolates, followed by phage type 4 (33,8 %). other phage types identified were 1, lb, 4a, 7, 7a, 9a, 14, 24, 24var and 35 (in total 2,4% of isolates). most isolates of se were recei ...200011028749
