Article Abstract
The present experiment was aimed at assessing the application of neostigmine, an acetylcholinesterase (AChE) pseudo-irreversible inhibitor with poor penetration through the hematoencephalitic barrier, and the neurotransmitter acetylcholine (ACh). The experiment was done to evaluate their ability to modulate an infectious disease: tularemia. Mice infected with Franciselle tularensis and exposed to either ACh or neostigmine had a higher mortality and spleen bacterial burden when compared to infected mice exposed to saline solution only. The activated cholinergic anti-inflammatory pathway suppressed pathways necessary for tularemia resolution. Administration of AChE inhibitors to the individuals suffering from tularemia is contra-indicatory. Drugs based on AChE inhibition should be restricted when tularemia or disease with a similar pathogenesis is suspected.

is a vector-borne zoonotic bacterium that causes tularemia, a disease of great importance for animal and public health. Although wild lagomorphs are considered one of the major reservoirs of this bacterium, information about the circulation of in European wild rabbit () and Iberian hare () populations in Europe is still very limited. In Spain, is present in northern central regions, with recurrent outbreaks occurring annually.
Tularemia is a re-emerging zoonosis in many endemic countries. It is caused by , a gram-negative bacterium and biological threat agent. Humans are infected from the wild animal reservoir, the environmental reservoir or by the bite of arthropod vectors.

Infective endocarditis (IE) is a serious health issue, and this study investigates the presence of Coxiella burnetii and Bartonella spp. in heart valves in Iran.
The research examined 146 patients who had heart valve surgery and found C. burnetii in 12 patients and Bartonella quintana in 15 patients, with two new C. burnetii genotypes identified.
The study suggests that more research is needed to improve prevention, diagnosis, and treatment methods for Q fever endocarditis and Bartonella endocarditis.
This report by the European Food Safety Authority and the European Centre for Disease Prevention and Control presents the results of zoonoses monitoring and surveillance activities carried out in 2023 in 27 Member States (MSs), the United Kingdom (Northern Ireland) and 10 non-MSs. Key statistics on zoonoses and zoonotic agents in humans, food, animals and feed are provided and interpreted historically. In 2023, the first and second most reported zoonoses in humans were campylobacteriosis and salmonellosis, respectively.
