Background: Human brucellosis, otherwise known as undulant fever, is one of the most widespread zoonotic diseases in the world. Even though 9%-15% of stillbirths are known to be caused by infectious diseases, the study of the link between human and the termination of births in humans is a topic that has received little attention. This study examines if there was an association between infection of undulant fever, an endemic zoonotic disease in the Maltese Islands from 1919 until 1954, and reproductive loss through stillbirths.
Methods: A univariate descriptive analysis was used to show the temporal trend of undulant fever time, as well as the age and sex distribution. Time series analysis was used to assess the relationship between time (months) and undulant fever cases with stillbirth proportions.
Results: On the island of Gozo, the majority of undulant fever cases for both males and females occurred in their reproductive period between 15 and 45 years of age. Based on regression analysis, undulant fever had a statistically significant effect on the stillbirth rate for males ( = 2.8986, = 0.0039). The effect of undulant fever on stillbirths was not significant for females ( = 0.9103).
Conclusion: This paper highlights the importance of undulant fever as having implications for the health burden in pregnant women and potential fetal loss through stillbirths in the contemporary context.

The Brucella abortus A19 attenuated live vaccine poses potential infection risks during practical applications and interferes with serological diagnostics, thereby affecting quarantine measures and the establishment of disease-free zones. Consequently, this study aimed to reduce its potential virulence, enhance its protective efficacy and differentiate it from wild-type strains by knocking out the immunosuppressive virulence gene btpB in the A19 strain. Using homologous recombination, we successfully obtained the A19ΔBtpB deletion strain.

Background: Brucellosis is a zoonotic infection transmitted to humans by ingestion of contaminated unpasteurized dairy products or via direct or indirect contact with infected animals. It is characterized by nonspecific symptoms like fever and joint pain, and laboratory findings including anemia, leukopenia, thrombocytopenia, or rarely pancytopenia. Here we report a case of brucellosis with thrombocytopenia that did not improve despite anti-brucella treatment and required intravenous immunoglobulin treatment.

Brucellosis is a neglected zoonotic infection in Nepal that is often underdiagnosed, particularly in regions considered to have low prevalence. Its presentation can mimic autoimmune or hepatic disorders, complicating timely diagnosis and management. Coexistence with hereditary conditions such as Gilbert syndrome can further obscure the clinical picture.

Many species from the genus are causative agents of the bacterial zoonosis brucellosis. Until recently, it was generally believed that these bacteria exhibit strict host specificity; however, recent findings suggest otherwise. is an atypical species, no threat to humans, with a broad host spectrum, primarily found in wildlife and rodents, and is the only species isolated from soil, aquatic environments, and frogs, suggesting its environmental persistence and adaptability to diverse ecological niches.

Background: Brucellosis is a zoonotic and multisystemic disease that is widespread worldwide and can present with many different clinical conditions, ranging from asymptomatic to serious and fatal conditions. Brucellosis may be linked to renal tubular and acute kidney damage, nephrotic syndrome, and various types of nephropathies.
Objective: Our research was carried out prospectively to investigate the relationship between brucellosis and various biochemical markers and particularly to investigate the role of renal tubular damage biomarkers.
