The organism is a typical Gram-negative rod, 1.5 to 3 µm in length and 0.5 µm wide. Suspect colonies should be isolated in pure culture and confirmed by a number of tests that characterize the pigment-producing and biochemical properties of P. aeruginosa ( Table 11-3 ).

Streptobacillus is a genus of fastidious microaerophilic Gram-negative bacteria, which grow in culture as rods in chains. [2] Their species associated with infection is S. moniliformis. Their reported susceptibilities and therapies are penicillin and erythromycin.

The bacterium S. moniliformis is a gram-negative pleomorphic rod occurring frequently in chains and tangled filaments with bulbous or Monilia-like swellings. The organism presents phenotypically as being facultatively anaerobic, non-motile, weakly ferments glucose and maltose, is catalase and oxidase-negative, does not reduce nitrate, and ...

2021年4月11日 · Microscopic observation of Gram-negative bacteria cells ranges from rods to bacillus, to cocci to spiral shapes which are the most commonly known shapes. However some exhibit special shapes such as coccobacillus, tetrads, palisades, trichomes, etc.

Streptobacillus moniliformis is a Gram-negative, nonmotile rod of variable length. The individual cells are not regularly shaped or stained, and thus pleomorphism is seen in smears. There is a tendency for spontaneous development of cell-wall-deficient L-forms (see Ch. 2). Consequently, growth on artificial media depends on certain additives ...

2025年1月19日 · Explore the complexities of gram-negative rods, focusing on their pathogenesis, immune interactions, and evolving antibiotic resistance. Gram-negative rods are a diverse group of bacteria that pose significant challenges to human health. They cause various infections, from urinary tract infections to more severe illnesses like pneumonia and sepsis.

Streptobacillus moniliformis is a microaerophilic, gram-negative pleomorphic bacillus transmitted by a bite or scratch from rodents (such as rats, mice, or squirrels) or carnivores that prey on them (such as dogs, pigs, ferrets, cats, or weasels).

革兰氏阴性菌 （英語： Gram-negative bacteria）泛指 革兰氏染色 反应呈红色的 细菌。 在 革兰氏染色 实验中，首先添加了 結晶紫，再添入另一种复染染料（通常使用 番红），从而将所有的革兰氏阴性菌染成 红色 或 粉色。 通过这种测试我们可以区分两种 细胞壁 结构不同的细菌。 [1] 革兰氏阳性菌 在反应后的除色溶液中将呈现結晶紫的颜色。 相較於 革蘭氏陽性菌，陰性菌通常會導致人類疾病——例如最具代表性的 大腸桿菌。 革兰氏阴性菌细胞壁中 肽聚糖 含量低，而 脂类 含 …
