Jobbins et al (2015) reported on the first large-scale assessment of renal carrier states of Leptospira sp among African wildlife in the Chobe national park in Botswana. Employing polymerase chain reaction (PCR) screens 69 different species were examined and 17 species (24.6%) tested positive for renal carriage of Leptospira sp. Findings revealed positive results in 31.4% (11/35) of mammals, 27.8% (5/18) of bird and 6.3% (1/16) of reptile species. The findings of their study revealed that all the positive sequences featured a region specific for pathogenic Leptospira. These were identical to Leptospira interrogans from banded mongoose Genbank :JX254899), and the pathogenic L. interrogans serovars Lai (Genbank:NR-076185) and Copenhageni (Genbank: NR-076199). Renal carriage states in warthog, white-tailed mongoose, Angolan free-tailed bat, African savannah hare, tree squirrel, aardvark, Cape turtle dove, southern ground hornbill, arrow-marked babbler, glossy ibis, barn owl and herald snake are all reported by the authors. A high prevalence of Leptospira sp DNA was also observed in banded mongoose (22.1%, n = 7/77) and brown rats (23.4%, n =18/77). The latter are both established carriers of Leptospira sp. in sub-Saharan Africa. More recently (2015) the authors also reported that, 43.0% of 42 Botswanan mongooses had PCR-positive kidney tissue and renal carriage was also detected in one Selous’ mongoose. East Africa Data has been reported to be scarce with no significant findings reported in wildlife (de Vries et al 2014) apart from a study in Djibouti which revealed a remarkably high seroprevalence in small groups of camels. of Leptospira hardjo in African buffalos (and cattle) was determined by Atherstone et al (2014) in the southwestern Uganda. Positive results were found in both cattle and African buffalo from two locations and the seroprevalence was 42.39% in African buffalo and 29.35% in cattle. Wildlife in the rest of the world A number of studies were published from different regions of the globe. Petrakovsky et al (2014) reviewed the status of leptospirosis in Latin America and the Carribean countries. They reported the following wildlife species to show serological evidence of infection by Leptospira sp. In Argentinia arboreal squirrels, south American gray foxes, wild and domestic carnivore (Leopardus geoffroyi) and pampas deer. In Brazil non-human primates (Cebus paella, Alouatta caraya, Nasua nasua), gray foxes (Cerdocyon thous), rodents (Dasyprocta sp.), capybaras , anteaters , armadillos, wild canids (Cerdocyon thous, Crysocyon brachyurus, Speothos venaticus, Pseudalopex vetulus), raccoons, white-lipped peccaries , collared anteaters, ocelots, marsupials, (Didelphis albiventris) and pumas. In Columbia Rattus rattus, Mus musculus, neotropical primates (Ateles fusciceps, Ateles geoffroyi, Cebus albifrons, Cebus paella, Cebus capuccinos and Saguinus leucopus), Puma, ocelot. (Panthera onca, Leopardus tigrinus). In Peru captive collared peccaries RT (Tayassu tajacu), capybaras, Rattus rattus, Proechymis, marsupials. Central Africa Duikers from five different species were serologically screened in the Ituri forest (in the then Zaire) and 5/61 had a single positive titre whilst 5/61 had positive titres against more than one serovar. The most common serovar was Leptospira interrogans hardjo. The seroprevalence 2016 MARCH 7
