Lots of scientific findings have been convinced and advanced the hypothetical ability of some animals, such Primate, to preserve daily well-being, using elements from its environment, especially plants. The aim of this study was to determine the possible relationship between the behavior of one Madagascan Lemur specie, living in Berenty Private Reserve, and their observed zero gastrointestinal parasite prevalence. Behavioral monitoring was conducted on eight adult Propithecus verreauxi: consumed plants were listed/recorded/harvested, its different plant parts were extracted and subsequent chemical families were identified. Lemur stools were also drawn for coproscopy and anthelminthic biological tests of plant extracts were performed. During the tracking, thirty-two plants composed the Berenty adult Propithecus verreauxi diet. Less than half (44.73%) of its extracts exhibited an anthelminthic effect according to the biological tests on Lemurostongylus sp. and 34.21% according to scientific literatures. A proportion of 47.06% of these plant extracts contained saponins. After coprological analysis, no Berenty adult Propithecus verreauxi stool contained gastrointestinal worm, all studied parasitic parameters were zero. Extracts of Berenty Propithecus verreauxi consumed plants demonstrated anthelminthic properties on gastrointestinal parasite: in vivo zero prevalence, in vitro inhibition of hatching egg and larvae paralysis. In addition to the confirmation of zoopharmacognosy theory, these outcomes may allow a possible establishment of natural anthelmintic ingredients for captive Lemurs.

Concern for the welfare of aquatic invertebrates produced on a commercial or industrial scale is gradually extending beyond the realm of science and becoming a requirement of other societal actors. In order to assess the welfare of Penaeus vannamei during the stages of reproduction, larval rearing, transportation, and growing-out in earthen ponds, this paper proposes protocols. It also discusses, based on a review of the literature, the procedures and viewpoints involved in the creation and use of on-farm shrimp welfare protocols. Four of the five areas of animal welfare nutrition, environment, health, and behaviour were the foundations upon which protocols were created. The indicators for the psychology domain were not thought of as belonging to a separate category, and the other suggested indicators only evaluated this domain inferentially. Apart from the three possible scores related to animal experience on a spectrum from positive to very negative, were defined based on literature and field experience. It is very likely that non-invasive methods for monitoring the welfare of farmed shrimp, like those suggested here, will become standard equipment for farms and labs, and that it will get harder to grow shrimp without taking their welfare into account at every stage of the production process.

The skin and mucous membranes of dogs are known to contain S. pseudintermedius, which is also a part of the canine body's typical microbiota. It has also been acknowledged as an opportunistic and zoonotic pathogen that can colonise people and cause serious illnesses, particularly in hosts who are immunocompromised. The most significant development is the emergence of the seriously detrimental to public health methicillinresistant S. pseudintermedius (MRSP), which is inherently multidrug resistant. Reports of its zoonotic transmission and human infections, which have primarily been attributed to the rising prevalence of dog ownership and close contact between dogs and humans, worsen the epidemiological situation. Limited information exists regarding the zoonotic spread of MRSP from pet dogs to humans, including dog owners, small-animal veterinarians, and other individuals who are in close proximity to dogs. Especially as a result of S. pseudintermedius being mistaken for S. aureus. Despite this, since its first documented report in Belgium in 2006, reports on the rising emergence and spread of MRSP in humans have been steadily rising over the years.
