Septelici D, Carbone G, Cipri A, Esposito S. Management Strategies for Common Animal Bites in Pediatrics: A Narrative Review on the Latest Progress. Microorganisms 2024; 12:924. [PMID: 38792754 PMCID: PMC11124134 DOI: 10.3390/microorganisms12050924] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2024] [Revised: 04/28/2024] [Accepted: 04/30/2024] [Indexed: 05/26/2024] Open
Abstract
Animal bites are a common reason for children to visit primary care and emergency departments. Dog bites are the most prevalent, followed by cat bites at 20-30%. Other animals such as bats, monkeys, snakes, and rats collectively contribute less than 1% of cases. Hospitalization is necessary in only 4% of animal bite incidents. The main aim of this narrative review is to summarize the main protocols currently followed in pediatrics in cases involving the most common bites from different animal species. Analysis of the literature showed that the management of common animal bites in children presents a multifaceted challenge requiring a comprehensive understanding of the epidemiology, clinical presentation, and treatment modalities associated with each specific species. Effective wound management is paramount in reducing the risk of infection and promoting optimal healing outcomes. Additionally, tetanus vaccination status should be assessed and updated as necessary, and prophylactic antibiotics may be indicated in certain cases to prevent secondary infections. Furthermore, the role of rabies prophylaxis cannot be overstated, particularly in regions where rabies is endemic or following bites from high-risk animals. In addition to medical management, psychosocial support for both the child and their caregivers is integral to the overall care continuum. Future studies exploring the efficacy of novel treatment modalities, such as topical antimicrobial agents or advanced wound dressings, may offer new insights into optimizing wound healing and reducing the risk of complications.

Surgical Management of Multijoint Septic Arthritis due to Rat-Bite Fever in a Pediatric Patient: A Case Study. Case Rep Orthop 2017; 2017:2183941. [PMID: 28255484 PMCID: PMC5306964 DOI: 10.1155/2017/2183941] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2016] [Accepted: 01/12/2017] [Indexed: 11/18/2022] Open
Abstract
In the United States, rat-bite fever is a rare systemic illness principally caused by Streptobacillus moniliformis, an organism found in the nasopharyngeal flora of rodents. Infection through direct exposure to rat excreta such as saliva, urine, or feces can lead to fever, rash, and an asymmetric migratory polyarthritis. As rodents are becoming more popular as pets, more pediatric cases are being documented. We report a pediatric case of delayed onset septic arthritis in the left wrist and right knee due to S. moniliformis from a rat bite. Previously reported pediatric case studies of suppurative arthritis due to S. moniliformis have only involved the hip. This case study demonstrates the importance of a thorough exposure history and consideration of zoonotic infections as a cause of septic arthritis in a pediatric patient that requires antibiotics and surgical intervention.

Rat Bite Fever Resembling Rheumatoid Arthritis. CANADIAN JOURNAL OF INFECTIOUS DISEASES & MEDICAL MICROBIOLOGY 2016; 2016:7270413. [PMID: 27366177 PMCID: PMC4904585 DOI: 10.1155/2016/7270413] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/12/2015] [Accepted: 03/30/2016] [Indexed: 11/20/2022]
Abstract
Rat bite fever is rare in Western countries. It can be very difficult to diagnose as blood cultures are typically negative and a history of rodent exposure is often missed. Unless a high index of suspicion is maintained, the associated polyarthritis can be mistaken for rheumatoid arthritis. We report a case of culture-positive rat bite fever in a 46-year-old female presenting with fever and polyarthritis. The clinical presentation mimicked rheumatoid arthritis. Infection was complicated by discitis, a rare manifestation. We discuss the diagnosis and management of this rare zoonotic infection. We also review nine reported cases of rat bite fever, all of which had an initial presumptive diagnosis of a rheumatological disorder. Rat bite fever is a potentially curable infection but can have a lethal course if left untreated.

Streptobacillus moniliformis bacteremia in a rheumatoid arthritis patient without a rat bite: a case report. BMC Res Notes 2015; 8:694.

Abstract
Background Rat bite fever is a relatively rare infectious disease due to infection with Streptobacillus moniliformis or Spirillum minus mainly via directs bite by rats, mice, or other rodents. If there is no clear bite history, the diagnosis is difficult or may not be made. Case presentation A 72-year-old Asian female with rheumatoid arthritis was admitted for high grade fever and walking difficulty with severe lumbago. Initially, we suspected lumber compression fracture with deterioration of rheumatoid arthritis, but Gram-negative bacilli were isolated from blood culture during hospitalization. The isolated organism was identified as S. moniliformis by 16S ribosomal ribonucleic acid (rRNA) sequencing. S. moniliformis is well known to be a primary causative organism of rat bite fever, but this patient had no history of rat bite. Had S. moniliformis bacteremia not been detected, she might have been treated for rheumatic exacerbation. Conclusion We emphasize the importance of performing appropriate microbial culture testing for identifying potential infectious diseases. We also conclude that S. moniliformis infection can become established with contaminated vehicle contact alone, not only as a direct result of a bite. We must keep mind that those working in places where rodents breed or are at risk of contact with rats or mice might be at risk for contracting this unusual disease.

Abstract
Rat bite fever (RBF) is a bacterial zoonosis for which two causal bacterial species have been identified: Streptobacillis moniliformis and Spirillum minus. Haverhill fever (HF) is a form of S. moniliformis infection believed to develop after ingestion of contaminated food or water. Here the infectious agents, their host species, pathogenicity (virulence factors and host susceptibility), diagnostic methods, therapy, epidemiology, transmission and prevention are described. Special emphasis is given on information from the field of laboratory animal microbiology and suggestions for future research.

Streptobacillus moniliformis septic arthritis: a clinical entity distinct from rat-bite fever? BMC Infect Dis 2007; 7:56. [PMID: 17561996 PMCID: PMC1903360 DOI: 10.1186/1471-2334-7-56] [Citation(s) in RCA: 35] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2006] [Accepted: 06/11/2007] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Streptobacillus moniliformis is a zoonotic agent associated with rodent contacts. Although it is more commonly reported to cause rat-bite fever with reactive arthritides, it can also lead to pyogenic infection of the joints. CASE PRESENTATION We present a lady with past history of osteoarthritis developing streptobacillary septic arthritides of the right knee and left wrist, and required antibiotic and arthrotomy for treatment. We also review 11 previously reported cases of streptobacillary septic arthritis to discuss the characteristics, treatment, prognosis of the infection, and illustrates the differences between streptobacillary rat-bite fever and septic arthritis. Among this patient population, most patients had potential contact with rats (91.6%). The knee is the most commonly affected joint (58.3%), and 83.3% patients having polyarticular involvement. As opposed to rat-bite fever, fever and rash was only present in 58.3% and 16.7% of patients respectively. S. moniliformis bacteremia is uncommon (8.4%) and the prognosis is good. CONCLUSION Arthrocentesis is useful in distinguishing streptobacillary septic arthritis from reactive arthritis of rat-bite fever. The sole use of commercial media containing sodium polyanethol sulfonate may render the bacterial culture negative. A detailed history of possible exposure to rodents should be elicited from patients with arthritis in order to facilitate microbiologic diagnosis.

Abstract
Pet-rat bite fever is a relatively rare disease consecutive to a rat bite or scratch. The authors report a case of septic arthritis following a pet rat bite. Streptobacillus moniliformis was identified in the knee synovial fluid and identified by 16S rRNA sequencing. This is a rapid and efficient tool for identification of fastidious bacterium. The patient was cured by an amoxicillin treatment.

Abstract
Rat-bite fever is a rare zoonotic infection caused by Streptobacillus moniliformis or Spirillum minus, which is characterised by fever, rash and arthritis. The arthritis has previously been described as non-suppurative and isolation of the organism from synovial fluid as very uncommon. This article reports a case of septic arthritis diagnosed as rat-bite fever when the organism was cultured from synovial fluid and reviews another 15 cases of S. moniliformis septic arthritis reported in the worldwide literature since 1985. Articles were included in this review if S. moniliformis was cultured from synovial fluid. Of the published cases, 88% presented with polyarthritis, affecting small and large joints although two had monoarticular hip sepsis. Fever was present in 88%, rash in 25% and 56% had extra-articular features. Synovial fluid analysis revealed high cell counts in all cases (mean 51,000 x 10(9)/l) with a predominance of polymorphonuclear leucocytes, and organisms were found on Gram stain in only 50%. Penicillin was used for treatment in 56% of cases and surgery was required in 30%. All patients recovered. Rat-bite fever arthritis can be suppurative and attempts should be made to isolate the organism from synovial fluid. The diagnosis should be considered when there is arthritis and a high synovial fluid cell count but no apparent organism, especially when the patient has had contact with rats.

Abstract
Rat bite fever, caused by Streptobacillus moniliformis, is a systemic illness classically characterized by fever, rigors, and polyarthralgias. If left untreated, it carries a mortality rate of 10%. Unfortunately, its nonspecific initial presentation combined with difficulties in culturing its causative organism produces a significant risk of delay or failure in diagnosis. The increasing popularity of rats and other rodents as pets, together with the risk of invasive or fatal disease, demands increased attention to rat bite fever as a potential diagnosis. The clinical and biological features of rat bite fever and Streptobacillus moniliformis are reviewed, providing some distinguishing features to assist the clinician and microbiologist in diagnosis.

Abstract
Streptobacillus moniliformis was identified as etiologic agent of arthritis utilizing a 16S rDNA molecular kit in our clinical laboratory. With the increasing of human contacts with rat as pet, this method would appear suitable to identify fastidious Gram-negative rod involved in arthritis specially when the clinical context is not evocative.
