“…[3] However, cases of C. testosteroni resistant to aminoglycosides and those resistant to aminoglycosides, carbapenems, and piperacillin-tazobactam have been reported in 2009 and 2015, respectively. [5] In line with the literature, the antibiogram of our case re- vealed that C. testosteroni was resistant to piperacillin-tazobactam (MIC, >128 µg/mL), imipenem (MIC, >16 µg/mL), meropenem (MIC, >16 µg/mL), and gentamycin (MIC, >16 µg/mL) and susceptible to colistin, levofloxacin, tigecycline, and cefepime.…”

Comamonas testosteroni, previously known as Pseudomonas testosteroni, is a gram-negative, aerobic, motile, pinkpigmented, oxidase-positive bacilli. It rarely infects humans and commonly lives in environments such as soil, water, plants, and animals; however, it also survives for a long time in hospital environments. C. testosteroni infections are often treated in humans, and thus, mortality is rare. To date, among 19 cases of C. testosteroni bacteremia in the literature, only four died owing to underlying diseases. Here we present a case of a 68-year-old male patient with underlying pulmonary malignancy who was positive for C. testosteroni and Staphylococcus haemolyticus in the blood culture and Acinetobacter baumannii in the tracheal aspirate culture. The patient died on the 16th day, despite appropriate treatments against etiological agents. The patient is the 20th bacteremia and fifth mortal case among 38 cases with C. testosteroni infection in the medical literature.

“…Exposure to high levels of endotoxins has been reported to influence immune responses towards Th2-type immune response [1832]. In addition, Gram-negative bacteria are commonly associated with hospital acquired infections in humans [11262842], indicating greater risk to immune compromised subjects. It is also important to note that the majority of microorganisms identified from most farms are linked to nosocomial infections in humans that usually involve antibiotic-resistant microorganisms.…”

Microorganisms found in bioaerosols from animal confinement buildings not only foster the risk of spreading diseases among livestock buildings, but also pose health hazards to farm workers and nearby residents. This study identified the various microorganisms present in the air of swine, chicken, and cattle farms with different kinds of ventilation conditions in Korea. Microbial air samples were collected onto Petri dishes with bacterial or fungal growth media using a cascade impactor. Endotoxin levels in total dust were determined by the limulus amebocyte lysate kinetic QCL method. Prevalent Gram-positive bacteria were Staphylococcus (S.) lentus, S. chromogenes, Bacillus (B.) cereus, B. licheniformis, and Enterococcus faecalis, while the dominant fungi and Gram-negative bacteria were Candida albicans and Sphingomonas paucimobilis, respectively. Considering no significant relationship between the indoor dust endotoxin levels and the isolation of Gram-negative bacteria from the indoor air, monitoring the indoor airborne endotoxin level was found to be also critical for risk assessment on health for animals or workers. The present study confirms the importance of microbiological monitoring and control on animal husbandry indoor air to ensure animal and worker welfare.

“…Now a day, this bacterium has been identified in various hospital devices; however, it has not been recognized as a component of the endogenous human microflora. Because this bacterium has been more frequently encountered (till now around 36 cases), we thought that this case would be beneficial for clinicians and laboratory physicians in their diagnosis and clinical approach[4] [Table 1]. Majority of the infections are community-acquired rather than nosocomial.…”

Bacteremia caused by Comamonas testosteroni an unusual pathogen

Comamonas species are rare isolates in microbiology laboratories and have been infrequently reported as an infectious agent in routine clinical practice. They have a wide range of natural habitats including water, soil, and plants as well as from some hospital devices, such as intravenous lines and the reservoir water in the humidifiers of respiratory therapy equipment. Comamonas testosteroni is rarely recognized as a human pathogen. In spite of its uncommon human pathogenesis, there are few reports where it was reported as an aggressive opportunistic pathogen, and that was mostly related to Testosterone species. Herewith, we are reporting this pathogen from the blood of an immunocompetent female. The aim of this case report is to alert clinicians and laboratory physicians for the potential diagnosis and clinical approach of bloodstream infections caused by such unusual pathogens. This is the first documented case of bacteremia caused by C. testosteroni from India.
