Cheetah

지구상 가장 빠른 육상 동물로, 아프리카와 이란의 초원에서 단거리 질주 시 시속 112km에 달하는 속도를 낸다. 깊은 가슴, 긴 다리, 독특한 흑색 눈물 줄무늬를 가진 날씬한 체형이 특징이다. 다른 대형 고양이과와 달리 치타는 지저귀는 소리와 그루링 소리를 낸다. 서식지 파편화와 대형 포식자와의 경쟁으로 인해 약 7,000마리만 남아 있으며 취약종으로 분류된다.

Clostridium tertium is an aerotolerant, endospore-forming bacterium in the family Clostridiaceae notable among clostridia for its ability to grow in the presence of atmospheric oxygen, despite being classified within the genus of strictly anaerobic organisms. Its relative aerotolerance distinguishes it from most genus members and contributes to its occasional isolation from clinical sources. C. tertium is considered an opportunistic pathogen, causing bacteremia primarily in immunocompromised patients including those undergoing chemotherapy, with neutropenia as a key risk factor. The bacterium has been isolated from soil, water, and the gastrointestinal tract of animals and humans. Despite causing bacteremia and occasionally more invasive infections, C. tertium does not produce recognized exotoxins comparable to the major histotoxic clostridia, and its pathogenic mechanisms involve host immune evasion rather than direct toxin-mediated tissue destruction. Clinically, C. tertium bacteremia carries significant mortality in neutropenic patients but responds to beta-lactam antibiotics unlike C. difficile or C. perfringens infections. Its natural aerotolerance makes it unusual within the Clostridium genus and raises evolutionary questions about the anaerobic ancestry of this lineage.
