Humans, like all living things, depend on their environment to meet their health needs, including their needs for food, water, and shelter. Deficiencies can occur due to inadequate resources or inequitable distribution of these resources. This material presents a number of tips that could enable people to adopt healthier lifestyles and thereby improve their quality of life.

Disinfection in animal farms represents an inseparable part of any zoohygienic program, since it constitutes, within disease prevention plans, one of the irreplaceable pillars. This is very important, since disinfection alone should not be seen as the solution to all infectious problems in animal husbandry enterprises, but as an integral part of the hygienic measures aimed at keeping the environment sanitary and thus contributing to the maintenance of the animals' health.

Leptospirose ist eine Zoonose, die durch das pathogene Bakterium Leptospira verursacht wird, das in den Nierentubuli bestimmter Tiere verbleibt. Der Mensch infiziert sich durch den Kontakt mit infizierten Tieren oder einer kontaminierten Umgebung. Die Leptospirose ist endemisch, mit epidemischen Ausbrüchen auf mehreren Kontinenten, und gilt als die am weitesten verbreitete Zoonose der Welt. Die Krankheit ist in verschiedenen Regionen der Welt aufgetreten. Die Verbreitung der Infektionsreservoire und der verschiedenen Leptospira-Serovare ist weltweit; sie tritt in städtischen und ländlichen Gebieten sowohl in Entwicklungsländern als auch in Industrieländern auf. Aus diesem Grund kann die Entwicklung dieser Krankheit auf allen Kontinenten beobachtet werden. In China ist sie endemisch, 74,8 % der Landwirte sind betroffen, wie eine von Hu Jing zwischen 1960 und 1995 durchgeführte Studie zeigt. In Indien ist sie sehr verbreitet. In Lateinamerika und in den Entwicklungsländern ist sie weit verbreitet, wo die sozioökonomischen Bedingungen und die schlechten sanitären Verhältnisse der Krankheit förderlich sind.

Leptospirosis is a zoonotic disease caused by the pathogenic bacterium Leptospira, which remains in the renal tubules of certain animals. Humans become infected when they come into contact with infected animals or with the contaminated environment. Leptospirosis has an endemic behavior, with epidemic outbreaks in several continents, and is considered the most widespread zoonosis in the world. It has been reported in different regions of the world. The distribution of the reservoirs of infection and of the different leptospira serovars is worldwide; it occurs in urban and rural areas, both in developing and developed countries. This is why the evolution of this entity can be observed in all continents. However, it predominates in tropical areas, in Southeast Asia, in China it is endemic, 74.8% of farmers are affected, according to a study conducted by Hu Jing from 1960 to 1995. In India, it is very frequent. In Latin America and in developing countries it is frequent, where socioeconomic conditions and poor sanitary conditions are conducive to the disease.

This book reviews general aspects related to probiotics and prebiotics for animal health, the most used microorganisms and the mechanisms of action described for such effects. It also deals with the most commonly used compounds as prebiotics in animals, emphasizing the results obtained with the use of oligosaccharides such as beta-glucans and fructans in the improvement of health and bioproductive indicators in production conditions.
