I photographed this lion at an isolated reserve were lions are bred to replenish/replace those dying from FIV.
FIV is a clear and present danger to African Lions.
FIV stands for Feline Immunodeficiency Virus. It is a virus that infects several species of felines, and is very similar to the HIV virus in humans. FIV attacks a feline's immune system. It is contagious and can be transmitted from one cat to another. There is no cure for FIV. The primary method through which FIV is transmitted is bite wounds. It is also possible for a mother infected with FIV to pass the virus along to her offspring through infected milk. Sexual intercourse is not currently thought to be a major route of FIV transmission.
In domestic cats, the effects of FIV are very similar to the effects of HIV in humans. FIV targets and destroys white blood cells, which are the basis of the immune system. As FIV continues to replicate and destroy more white blood cells, the immune system becomes severely compromised and makes the cat vulnerable to other diseases. In domestic cats, FIV is fatal. Like HIV, death usually occurs as a result of complications from some other disease because of the compromised immune system.
FIV is very common in the Serengeti National Park. Studies done found that 91% of the lions tested (221 out of 243) were FIV positive. FIV is also very common in the Ngorongoro Conservation Area, with 93% of the lions tested (41 out of 44) testing positive for FIV. Similar results were found in Kruger National Park in South Africa, where 91% of the lions tested (50 out of 55) were positive for FIV.
There is no evidence that humans can become infected with FIV. Researchers and veterinarians that have been bitten by FIV positive cats have consistently tested negative for FIV. |

Just added some Unsharp Mask in Photo shop to bring out more details. It is always a good idea to sharpen the photo once being done working on it. Usually i do it several times, while re-sizing the photo for the web. I do my re-size in several steps and apply a tiny amount of USM for each step. In this way i get to keep the details of the shot and the quality loss is less. If i have a shot which is 1800 px wide i first re-size it to 1500 px, apply some USM, then re-size it to 1300 px and apply USM, then 1100 px + USM and fianly 800 px + USM. Usually i set the amount to somewhere between 10-25% when sharpening during the re-size and the radius is set to 0,5 (at all times).
Hope you like it
Regards
