TL;DR
The clinical and epidemiological features of this family cluster and omp28 sequencing and phylogenetic analysis of the index case highlight the public health significance of B. abortus transmission in an underserved urban community and reinforced the need of an integrated One Health surveillance and control program from brucellosis beyond rural areas.
Abstract
Brucellosis is a neglected bacterial zoonosis caused by Brucella spp. with worldwide distribution. Infection typically occurs through direct contact with infected animals or consumption of unpasteurized dairy products, and the global burden of brucellosis is estimated over two million cases per year. In Latin America, brucellosis remains endemic, with important public health and economic consequences. Here, we report a family cluster of brucellosis in Guayaquil, Ecuador, involving six confirmed cases, including pediatric patients. We describe the clinical and epidemiological features of this family cluster and present omp28 sequencing and phylogenetic analysis of the index case, highlighting the public health significance of B. abortus transmission in an underserved urban community. The epidemiological link of this urban family cluster to unpasteurized dairy products reinforced the need of an integrated One Health surveillance and control program from brucellosis beyond rural areas.
Bovine brucellosis is a chronic infectious and zoonotic disease with high prevalence in herds from low and middle-income countries. In these locations, epidemiological and sanitary surveillance is often insufficient to contain high-volume production systems. The etiological agent is the Gram-negative bacterium of the g...

Despite the control of Triatoma infestans in Brazil, other vectors remain implicated in the transmission of Chagas disease, making the maintenance of municipal entomological surveillance and health education actions indispensable. This study reports on the colonization of a home by triatomine bugs in a mattress, eviden...

Echinococcus is a taeniid cestode of public health concern with a cosmopolitan distribution that can be transmitted between animals and humans. Cystic echinococcosis caused by E. granulosus is among the neglected zoonotic tropical diseases highlighted by the World Health Organization, aiming to diminish the disease bur...

Eosinophilic meningitis due to Angiostrongylus cantonensis (AC) is an emerging parasitic disease worldwide but remains endemic in the Pacific region. In New Caledonia, sporadic cases occur each year, and the route of transmission is often unclear. In January 2023, an unusual cluster of three cases occurred in a village...

Simple Summary Leishmaniasis is a neglected tropical disease prioritized by the World Health Organization and transmitted by infected sand flies. Dogs are the primary reservoirs of Leishmania infantum, the parasite responsible for zoonotic visceral leishmaniasis, a severe form of the disease. This study assessed the pr...
