Burkholderia Cepacia Complex (BCC): A Review of its Infectious Disease Profile

The Burkholderia cepacia complex (BCC) is a group of bacteria that has been associated with serious respiratory infections in patients, particularly those with underlying health conditions. The BCC has emerged as a worrying opportunistic pathogen, with high potential to cause severe and life-threatening infections.

Characteristics of the BCC

• The BCC is a group of non-fermenting and oxidase-positive aerobic Gram-negative bacilli [1].
• They are commonly found in soil and water [5].
• The BCC is known to be highly resistant to antibiotics, making treatment challenging [9].

Infectious Disease Profile

The BCC has been associated with high morbidity and mortality rates, particularly among patients with cystic fibrosis [9]. Infections caused by the BCC can lead to severe respiratory symptoms, including pneumonia and sepsis.

• The BCC is a known serious threat to patients with cystic fibrosis, in whom it has the potential to cause severe and life-threatening infections [9].
• They commonly affect patients with compromised immune systems or underlying health conditions [7].

Historical Context

The BCC was historically known as a rare and unusual pathogen. However, recent studies have highlighted its increasing prevalence and virulence.

• This group of bacteria has emerged as a worrying opportunistic pathogen, with high potential to cause serious respiratory infections in patients with underlying health conditions [3].
• The BCC is a group of non-fermenting and oxidase-positive aerobic Gram-negative bacilli [2].

Burkholderia Cepacia Complex (BCC) Infectious Disease Signs and Symptoms

The Burkholderia cepacia complex (BCC) is a group of bacteria that can cause serious respiratory infections in patients with underlying health conditions. The signs and symptoms of BCC infection can vary depending on the individual, but here are some common manifestations:

• Respiratory Infections: Pneumonia, bronchiectasis, pyopneumothorax, and other severe respiratory infections have been reported in immunocompetent hosts [2][5].
• No Symptoms to Severe Respirations: BCC can range from no symptoms to severe respiratory infections and septicemia, particularly in patients with cystic fibrosis or chronic granulomatous disease [3][6].
• Gastrointestinal Symptoms: Patients may present with diarrhea, abdominal pain, constipation, weight loss, failure to thrive, presence of granulomas, and perianal and liver abscesses [7].

It's essential to note that BCC is an opportunistic pathogen, meaning it primarily affects individuals with weakened immune systems or underlying health conditions. If you suspect someone has been infected with BCC, seek medical attention immediately.

Based on the provided context, it appears that there are several diagnostic tests mentioned for the Burkholderia cepacia complex (BCC) infectious disease.

• Conventional Polymerase Chain Reaction (PCR): This test is mentioned in search result 2 as a method used to identify Bcc species and assess clonal relatedness.
• Whole-genome sequencing (WGS): Search result 7 mentions the use of WGS to treat persistent Bcc bacteremia. WGS is a diagnostic tool that can provide detailed information about the genetic makeup of an organism, including bacteria like BCC.
• Ceftazidime-avibactam: This antibiotic combination is mentioned in search result 7 as a treatment for persistent Bcc bacteremia.

It's worth noting that while these tests and treatments are mentioned, they may not be relevant to diagnostic tests for obsolete BCC infectious disease. The term "obsolete" suggests that the disease or condition being referred to is no longer current or relevant.

However, based on the context provided, it seems that the focus is on identifying and treating BCC infections in general, rather than specifically targeting an obsolete form of the disease.

Treatment Options for Obsolete Burkholderia cepacia Complex Infections

Burkholderia cepacia complex (Bcc) infections are a serious and often life-threatening condition, particularly in individuals with compromised immune systems. While the exact treatment options may vary depending on the severity of the infection and individual patient factors, here are some general approaches that have been explored:

• Co-trimoxazole: Historically, co-trimoxazole (trimethoprim/sulfamethoxazole) has been a drug of choice for treating Bcc infections [2]. However, its effectiveness can be limited by the emergence of resistant strains.
• Ceftazidime-avibactam: This antibiotic combination has shown promise in treating persistent Bcc infections, particularly those caused by multidrug-resistant strains [1, 4].
• Non-standard antibiotic combinations: Research has also explored the use of non-standard antibiotic combinations to combat multidrug-resistant Bcc bacteria [7].

Important Considerations

It's essential to note that treatment decisions for Bcc infections should be made on a case-by-case basis and may involve a team of healthcare professionals. The choice of antibiotic therapy will depend on various factors, including the severity of the infection, individual patient characteristics, and local resistance patterns.

Burkholderia cepacia complex (Bcc) infections have been a significant concern in the past, particularly among cystic fibrosis patients and those with compromised immune systems. However, with advancements in medicine and increased awareness, the incidence of these infections has decreased.

• Historical context: Bcc infections were more common in the 1990s and early 2000s, especially among individuals with cystic fibrosis (CF) or chronic granulomatous disease (CGD). These patients were often exposed to contaminated water sources, medical equipment, or other environmental factors that facilitated the spread of the bacteria.
• Clinical manifestations: Bcc infections can manifest in various ways, including respiratory tract infections, skin and soft-tissue infections, surgical-wound infections, and genitourinary tract infections. In severe cases, they can lead to septicemia, especially in patients with CF or CGD.
• Diagnostic challenges: Differentiating Bcc from other bacterial pathogens can be difficult due to the similarities in their clinical presentations. However, various diagnostic methods have been developed to aid in the identification of Bcc, including molecular techniques and biochemical tests.

Current status:

While Bcc infections are still a concern for certain patient populations, the incidence has decreased significantly since the early 2000s. This decline can be attributed to:

• Improved infection control practices: Enhanced protocols for sterilization, disinfection, and proper handling of medical equipment have reduced the risk of transmission.
• Increased awareness and education: Healthcare providers are now more vigilant in identifying and managing Bcc infections, which has led to better patient outcomes.
• Advancements in antimicrobial therapy: The development of effective antibiotics and other treatments has improved the management of Bcc infections.
