Hello

I'm looking for scientific info regarding the closing of artificial waterholes in kruger and maybe the effects that it will have on the lions . I also would like some scientific info on TB in the lion populations in kruger. I have looked in koedoe journals, JSTROR, Science direct and Ebscohost databasis but only found info on TB in Buffalo.

Will you please be so kind in forwaring info for me. Should you nt be able to assist me will you please be so kind in giving me contact details of someone that will have access to info.
Many thanks

Sincerely

50/50 TB lions in Kruger
You might get some info on TB from SABC
Will investigate further for you

Take a look at this thread as well. Starts out speaking about lions' weird eyes, and morphs into some discussion on TB, feline and bovine.

Estimating lion population variables: Prey and disease effects in Kruger National Park, South Africa

Sam M. Ferreira and Paul J. Funston

Abstract: Lion (Panthera leo) populations experience a range of ecological and human influences that affect their demography. Few lion populations have reliable estimates of population size, trends in these, or demographic profiles. We developed a statistically robust approach to estimate selected population variables and evaluated the perceived threat of bovine tuberculosis (BTb) in landscapes of varying prey biomass in the Kruger National Park. Lion population size was stable, but long intervals between present and historical estimates limit this conclusion. Density and survival rates associated positively with prey biomass. Some variation in survival rates associated with prevalence of BTb - survival was higher in areas that had high prevalence of BTb. Male survival was lower than that of females disregarding the effects of prey biomass or BTb prevalence. Body condition of lions was high with scores lower at low to medium prey density. The effect of an exotic disease on the Kruger lion population may be negligible at present. Intra-specific competition in areas where lions live in high densities affects survival rate. However, droughts could disrupt the hierarchical influences of prey biomass and BTb prevalence on lion densities and survival. To evaluate the effect of an exotic disease on lion demography, population surveys should include age- and sex-structure assessments complemented by focal studies of fecundity.

Had a recent disccussion with the Manager of Conservation Services.

He stated that there is currently a decline observed in affected animals in the KNP, certain Buffalo herds had an infection rate of up to 60%, it is now down to 30% infection rate in the Southern Area of the Park, with even much less in the Northern Areas; the number of infected Lions is also reducing, indicating that a resistance against Bovine TB is now being formed - again Mother Nature is taking care - the SURVIVAL of the FITTEST.

Any updates on this?

I didn't see any really bad looking lions in Kruger over the past long weekend.
Was really good to see this post on bTB.

Is the future looking bright?

Hi All,

On my recent trip to KNP I saw quite a large pride of lions not far from Skukuza between the Sabie and Sand low level bridges.

There must have been approx 10 adults, all looking healthy and in good condition. But there was a litter of young cubs that were in terrible condition. Totally emaciated with chunks of fur missing and bones sticking out.

My question is:
Were these cubs in poor condition due to lack of food? The adults looked healthy and well fed though.

Or was it tb? Would tb just affect cubs only and not the adults?

Thanks
Yoda

TB tends to affect old and sick animals the worst, though young ones may also be affected.

I somehow doubt whether this was TB. Always remember that TB is but one of a vast array of negative things that may affect lions.

Young lions in a pride do not get preferential treatment when it comes to feeding, and when a pride goes through a lean period, they are the first to suffer, and may show the most signs of stress.

One can only speculate.

Hey, yoda!

Their mother is probably dead or dysfunctional, and there is no other lactating or willing lioness...

The bad skin often indicates mange, a parasitic infection targeting weak mammals across the spectrum.

As Imberbe says, one can only speculate! :(

Can anyone tell me if the T-shaped mark that I have seen on the flanks of buffalo and lion in KNP is an indicator that they have been tested for BTB? Or that they have BTB? Or that they are BTB-free?

just a question, how does TB in Kruger develop, does it reducing itself, stagnation or what?

I think it was first identified in buffalo in Kruger about 20 years ago. It is possible that it was picked up from domestic cattle on a boundary somewhere. The bacterium can survive in soil for up to several months so I guess it could be picked up by grazing animals Because buffalo are an important food source for lions the disease can be passed along the food chain; an entire pride can come into contact with the bacterium when feeding on a buffalo carcass.

@ salamandA

Did to refer to my Post? Because that didn´t answered my question. My Question is: Does TB is still a Problem or not?
