obsolete opportunistic Moraxellaceae infectious disease

Obsolete Opportunistic Moraxellaceae Infectious Disease

The term "obsolete opportunistic Moraxellaceae infectious disease" refers to a type of infection caused by bacteria belonging to the family Moraxellaceae, which is no longer considered a significant or current health concern.

• Formerly known conditions: In the past, infections caused by Moraxellaceae were referred to as "Moraxellaceae infections," "Psychobacter infections," and "Infection, Moraxellaceae" (1).
• Current understanding: The family Moraxellaceae now includes several genera, including Moraxella, Psychrobacter, and Acinetobacter. While some members of this family can still cause infections in humans, the specific condition referred to as an "obsolete opportunistic Moraxellaceae infectious disease" is no longer considered a significant health concern (2).
• Replaced by more accurate terminology: The use of the term "obsolete opportunistic Moraxellaceae infectious disease" has been replaced by more specific and accurate terms that describe the actual conditions caused by these bacteria, such as infections with Acinetobacter or Moraxella catarrhalis (3).

Based on the provided context, it appears that there are several diagnostic tests that can be used to identify infections caused by Moraxellaceae, an order of bacteria that includes opportunistic pathogens such as Moraxella catarrhalis and M. osloensis.

• Molecular identification: The 16S rRNA gene sequencing method has been reported as a successful method for accurate identification of M. osloensis [5]. This technique can be used to confirm the presence of Moraxellaceae bacteria in clinical specimens.
• Biochemical tests: While conventional biochemical methods may not always be sufficient to identify M. osloensis, they can still be useful in distinguishing it from other bacteria [14].
• PCR and RT-PCR: The addition of PCR (Polymerase Chain Reaction) to conventional diagnostic methods increases the probability of finding the causal agent in CNS infections [3]. More specific tests such as viral isolation, in situ hybridisation, and reverse transcription-polymerase chain reaction (RT-PCR) are required to confirm H5N1 infection [4].
• Culture collection strains: Culture collection strains of Neisseriaceae and Moraxellaceae were studied to identify established human pathogens and emerging causes of opportunistic infections [10].

It's worth noting that the diagnostic tests mentioned above may not be specific to obsolete opportunistic Moraxellaceae infectious diseases, but rather can be used to identify these bacteria in general.

Molecular analysis based on DNA hybridisation or 16S rDNA sequence comparisons has established its phylogenetic position as a member of the Moraxellaceae and shown that it is ...

Based on the provided context, it appears that you are looking for a differential diagnosis for an obsolete opportunistic Moraxellaceae infectious disease.

Possible Differential Diagnoses

• Dry eye disease [10]

Note on Moraxellaceae Infections

Moraxella catarrhalis, a member of the Moraxellaceae family, has been reported to cause various infections, including otitis media, sinusitis, and respiratory tract infections. However, it is worth noting that some sources consider this bacterium to be an opportunistic pathogen, which may have led to its classification as obsolete in certain contexts.

Relevance of 16S rDNA Region

According to a study by D. Harmsen [3], the 16S rDNA region is more suitable than the partial 23S rDNA for the molecular diagnosis of Neisseriaceae and Moraxellaceae. This information may be relevant in identifying the causative agent of an infectious disease.

Other Considerations

It's also worth noting that members of the Genus Bacteroides are mostly nonpathogenic commensals, living in the human GI tract; some are opportunistic pathogens [8]. However, this information does not seem directly related to Moraxellaceae infections.
