Bacteria Weekly

Bacteria of the Week: Ureaplasma urealyticum . . . Founded by: Shapard et al in 1954 . . . Five Fun Facts: 💡Because of the lack of cell wall, this bacterium requires unique physiology and medical treatment 💡Cholesterol is required for its growth 💡The genome size ranges from 0.76-1.17 million base pairs 💡One of this bacterium's genus defining characteristic is the ability to perform urea hydrolysis 💡The infection has been linked to infertility in both males and females Symptoms of Urethritis: - Blood in the urine or semen - Burning pain while urinating - Frequent urination . . .

Bacteria of the Week: Rothia dentocariosa . . . Founded by: Georg and Brown in 1967 . . . Five Fun Facts: 💡The reason for the discovery of this bacterium stems from a case of tooth decay 💡The bacterium is mainly benign but can still cause a disease--though it is very rare 💡There was a single report of fetal fatality in utero despite its harmless nature 💡Infection of this bacterium can be treated with antibiotics like penicillin. 💡Since it is an oral bacteria, it can reduce nitrate to nitrite Symptoms of Endocarditis: - fever - chills - night sweats - headaches - cough - fatigue - shortness of breath - muscle and joint pain . . .

Bacteria of the Week: Ehrlichia ewingii . . . Founded by: Sh. D. Moshkovsky in 1937 . . . Five Fun Facts: 💡The bacterium is sensitive to mechanical stress and changes in osmolarity. 💡It uses host cell machinery to replicate its genome 💡The reason for difficulty in diagnosing in this infection is the symptoms are unspecific. 💡Estimated fatality rate is 1.8% 💡The infection can be determined under blood tests Symptoms of Ehrlichiosis: - fever - headache - fatigue - muscle aches . . .

Bacteria of the Week: Brucella abortus . . . Founded by: Bernard Bang in 1897 . . . Five Fun Facts: 💡Farm workers and veterinarians are at highest risk to B. abortus because work with animals. 💡Animals like cattle, swine and goats are the reservoirs for the disease 💡It's a zoonosis (a disease caused by a pathogen that has the ability to jump from animal to human, vice versa) 💡Common ways humans are infected by this bacterium is drinking unpasteurized milk from infected animals while animals and be infected through one another, leading to livestock abortions if not treated. 💡The bacterium can survive longer in cool temperature and liquids like milk. Symptoms of Brucellosis: - fever - chills - headache - backache - weight loss . . .
