Rat bite fever is a bacterial zoonosis transmitted through the bite of rats. One of the two etiological agents that cause rat bite fever is Streptobacillus moniliformis. Rat bite fever is rare and very likely under diagnosed but occurs worldwide.

What causes Streptobacillus moniliformis?
Streptobacillosis is a more common form of rat-bite fever, and it is also known as epidemic arthritic erythema. It is caused by Streptobacillus moniliformis and is transmitted by rat bite or ingestion of contaminated products usually milk (Haverhill fever).
What causes Streptobacillus?
Rat-bite fever (RBF) is an infectious disease caused by two different bacteria: Streptobacillus moniliformis, the only reported bacteria that causes RBF in North America (streptobacillary RBF) Spirillum minus, common in Asia (spirillary RBF, also known as sodoku)
Do all rats carry Streptobacillus moniliformis?
Rats are thought to be the reservoir hosts for Streptobacillus moniliformis, and usually carry this organism asymptomatically. It can be found in both Rattus rattus, the black rat, and R. norvegicus, the Norwegian rat, which is the ancestor of most laboratory and pet rats.
Which creature spread rat fever?
Epidemiology. Rat-bite fever (RBF) is a zoonotic disease that was first reported in la Réunion, France in 2009. It can be directly transmitted by rats, gerbils, and mice (the vectors) to humans by either a bite or scratch or it can be passed from rodent to rodent.
Where is Streptobacillus found?
Streptobacillus is a genus of fastidious Gram-negative bacteria having forms that include filaments, chains, and curved rods. Streptobacillus moniliformis is predominantly found in the upper respiratory tract of rat, and is known as the main pathogenic cause of rat bite fever [1].
What does Streptobacillus look like?
Morphology. Streptobacillus moniliformis is a highly pleomorphic, filamentous, gram-negative, nonmotile, and non-acid-fast rod. It usually appears straight but may be fusiform and may develop characteristic lateral bulbar swellings. The organism is typically arranged in chains and loosely tangled clumps (Fig.
Is Streptobacillus harmful?
Less commonly the infection can cause pneumonitis, endocarditis or meningitis. As these symptoms are common to many febrile diseases, this is often classified as a fever of unknown origin (FUO). If untreated, death will occur in approximately 10% of cases.
What is Streptobacillus?
: any of a genus (Streptobacillus) of nonmotile gram-negative rod-shaped bacteria in which the individual cells are often joined in a chain especially : one (S. moniliformis) that is the causative agent of one form of rat-bite fever.
What happens if rat bites to human?
Rat bites usually look like a small, single puncture wound or a number of small cuts. They also tend to bleed and cause painful swelling. If the bite becomes infected, you might also notice some pus.
What happens if a rat bites me?
The common symptoms of a rat bite are pain, redness, swelling around the bite and, if secondary infection occurs, a weeping, pus-filled wound. Other rat bite symptoms may include those associated with bacterial infections known as streptobacillary rat bite fever and spirillary rat bite fever.
Are rats carriers of rabies?
Small rodents (like squirrels, hamsters, guinea pigs, gerbils, chipmunks, rats, and mice) and lagomorphs (including rabbits and hares) are almost never found to be infected with rabies and have not been known to transmit rabies to humans.
What is Sudoku disease?
Sodoku (鼠毒) is a bacterial zoonotic disease. It is caused by the Gram-negative rod Spirillum minus (also known as Spirillium minor). It is a form of rat-bite fever (RBF).
Can pet rats give you rat bite fever?
However, few, if any of the pet rats sold are tested for the bacteria that cause rat-bite fever. The prevalence of the bacteria in rats can vary, from as few as 10% to as many as 100% of rats in a breeding colony or laboratory that are infected.
Which disease is spread by rats?
There are disease concerns with both wild (rats, mice) and pet (rats, mice, hamsters, gerbils, guinea pigs) rodents and rabbits. They can carry many diseases including hantavirus, leptospirosis, lymphocytic choriomeningitis (LCMV), Tularemia and Salmonella.
