UTI caused by Morganella morganii

Understanding Morganella morganii and Its-Associated UTI

Morganella morganii is an uncommon, but pathogenic Gram-negative bacteria that is capable of causing a variety of urinary tract infections (UTIs). Its ubiquitous presence in the environment, and wide spectrum of symptoms associated with UTIs, can make identification of an M. morganii infection somewhat difficult.

M. morganii is closely related to the more common and pathogenic Enterobacteriaceae family of bacteria, and was initially discovered in 1889 by the US Army Medical Corps. It remains an organism of concern due to its numerous virulence factors which allow it to cause a range of infections including UTI.

Types of UTI

M. morganii can cause both cystitis and pyelonephritis, two types of UTI, but is most common in cases of cystitis. This is mostly due to the fact that M. morganii can colonise the bladder, due to its long-term survival and adaptation in the bladder environment.

Symptoms of UTI Caused by M. Morganii

Patients infected by a Morganella morganii UTI will usually experience a number of different symptoms, these can include:

• A burning sensation when passing urine
• Pain in the lower abdomen
• Frequent and urgent need to pass urine
• Urine that has a bad odor
• Cloudy or bloody urine
• Fever and chills

Diagnosis and Treatment of UTI Caused by M. Morganii

UTIs caused by M. morganii are usually treated in the same way as other UTIs. Initial diagnosis is usually done using a combination of urinalysis and urine culture, with antibiotics then prescribed to eliminate the infection. Commonly used antibiotics include fluoroquinolones, such as ciprofloxacin and levofloxacin, as well as combination therapy with nitrofurantoin and ampicillin.

In order to prevent future recurrences of Morganella morganii UTIs, it is essential to also try to identify any underlying causes. These could include voiding problems, urinary incontinence, or anatomical abnormalities.
