Intensive contact between herdsmen and their livestock, together with the use of pastures without fencing, allows contact between wildlife, domestic animals and humans, thus creating ideal conditions for epizoonoses and zoonoses. Consequently, ticks and TBPs cause significant medical, veterinary, and economical concern. This review summarizes the current state of knowledge about this zoonotic problem in Mongolia, focusing on tick species from the genera Ixodes, Haemaphysalis, Dermacentor, Hyalomma, and Rhipicephalus, which are associated with particular vegetation zones of the country. The most important tick species of medical and veterinary concern are Ixodes persulcatus and Dermacentor nuttalli, which are found in northern boreal forests and central steppes, respectively. These tick species transmit a wide variety of TBPs, including tick-borne encephalitis virus, Borrelia, Anaplasma, and Rickettsia bacteria, and Babesia parasites infecting rodents, wild ungulates, livestock, and humans. Despite basic characteristics of the biology of ticks and TBPs in Mongolia bei...

This study aims to assess the prevalence, distribution, and etiological profile of intestinal parasitism in children living in periurban areas in Cachoeiras de Macacu, Rio de Janeiro, Brazil. A community-based cross-sectional survey (n = 479) was carried out. Prevalence of infection with G. duodenalis and E. histolytica/E. dispar was 8.6% (n = 41) and 13.4% (n = 64), respectively. Infection with G. duodenalis was significantly more frequent among children living in poor families (24/187 (12.8%) vs. 16/272 (5.9%); prevalence ratio (PR) = 2.18; 95% confidence interval (...

Conclusion: Comprehensive health education related to zoonotic diseases is recommended to improve overall knowledge, including routes of transmission, symptoms and consequences of diseases, and antibiotic usage. In addition, guidance should be provided to farmers on how to treat sick animals, the appropriate use of antibiotics, and waste management. Local veterinarians and health workers are important contact points and should work closely with the farmers to prevent zoonotic diseases. PMID: 32733124 [PubMed]

Authors: Mhlanga A Abstract To better understand the dynamics of zoonotic diseases, we propose a deterministic mathematical model to study the dynamics of zoonotic brucellosis with a focus on developing countries. The model contains all the relevant biological details, including indirect transmission by the environment. We analyze the essential dynamic behavior of the model and perform an optimal control study to design effective prevention and intervention strategies. The sensitivity analysis of the model parameters is performed. The aim of the controls is tied to reducing the number of infected humans, through he...

Conclusion: This study may be useful for the implementation of future adequate measures and controls. Getting rid of leishmaniasis requires a comprehensive approach by acting on the sources of contamination through good continuous surveillance, appropriate management, effective vector control, and awareness-raising strategies.
