AI Article Synopsis
- A 78-year-old farmer developed a corneal abscess caused by Listeria monocytogenes, a pathogen that is resistant to certain antibiotics.
- Initial treatment included multiple antibiotics, but Listeria was identified only after two days of lab culture, revealing its resistance to some of the prescribed medications.
- The case highlights the importance of considering Listeria in ocular infections for high-risk populations like farmers and emphasizes the need for thorough microbiological analysis to guide effective treatment.
Article Abstract
Purpose: To report a farmer's corneal abscess caused by an unusual pathogen: Listeria monocytogenes fluoroquinolone resistant.
Methods: A 78-year-old farmer presented a central corneal abscess associated with 1-mm hypopyon and decreased visual acuity evolving since 2 weeks. First an antibiotic therapy associating oral ofloxacin and topical ciprofloxacin, vancomycin and ceftazidime was started. Different samples of the abscess were performed and sent to different microbiological laboratories.
Result: Listeria monocytogenes was isolated after 2 days of culture. Antibiotics sensitivity showed resistance to ciprofloxacin, fosfomycin and fusidic acid. Ceftazidime was changed for gentamicin, and after 1 month of treatment the abscess decreased considerably.
Conclusion: This case demonstrated that even if Listeria is rarely involved in ocular abscess, it must be evocated for people with risk factors as farmers. This suspicion should lead to an extended incubation to identify the pathogen. The analysis of Listeria resistance is essential to start an efficient therapy.

The process of discovering new drugs related to microbes through traditional biological methods is lengthy and costly. In response to these issues, a new computational model (NRGCNMDA) is proposed to predict microbe-drug associations. First, Node2vec is used to extract potential associations between microorganisms and drugs, and a heterogeneous network of microbes and drugs is constructed.

During the 2019 Chinese National Microbiological Food Safety Surveillance program, was detected in ice cream samples produced by Manufacturer A. By comparing the sequences of isolates derived from the ice cream with those of isolates derived from humans, we identified one human-derived isolate that was genetically indistinguishable from one ice cream-derived isolates. The patient was hospitalized with listeriosis in Beijing, China in March 2019.

Abortion is one of the major causes of economic losses in livestock production worldwide. Because several factors can lead to abortion in cattle, sheep and goats, laboratory diagnosis, including the molecular detection of pathogens causing abortion, is often necessary. Bacterial zoonotic diseases such as brucellosis, coxiellosis, leptospirosis, and listeriosis have been implicated in livestock abortion, but they are under diagnosed and under-reported in most developing countries, including Botswana.

In the absence of data on the reporting of resistance to antibiotics, we sought to determine which clonal complexes (CCs)/sequence types (STs) circulate in the food chain in Kosovo and to determine their antibiogram profiles to a panel of 18 antibiotics. From a total of 114 isolates, 21 different typical STs were identified by multilocus sequence typing (MLST). Each isolate derived from the food categories was subjected to tests to verify its susceptibility to the selected antibiotics according to the designed Sensititre GPN3F panel.
