Ticks are important ectoparasites and can transmit a wide variety of pathogens to animals and humans worldwide. These ectoparasites are the most important vectors of diseases causing pathogens in domestic and wild animals, and the second for man. In Brazil, Spotted Fever is the only disease transmitted to humans by ticks, while for animals we can highlight babesiosis, ehrlichiosis and anaplasmosis. Although ticks are found in all of Brazil’s biomes, little is known about its diversity and host-relations in the Amazon biome. The existing gaps and the lack of research indicate that the diversity of ticks and their possible pathogens are underestimated in the Brazilian Amazon. Therefore, in order to guide the next studies in the Amazon biome, we present in this chapter a compilation of the records of hard ticks and soft ticks parasitizing wild and domestic animals, and humans. We present the general list of ticks for this biome, their distribution, hosts and importance for public health and veterinary. Finally, the ixodofauna found in the Brazilian Amazon and presented here does not match the vertebrate diversity of this biome, which is one of the largest on the planet. Therefore, more acarologists and epidemiologists are needed in this region.

This study focused on many kinds of ticks distributed in Iraq and on various kinds of domestic and wild animals, and the distribution of ticks affected by the environment such as temperature and humidity,and to identify the diseases caused by ticks where the vertebrates are exposed to many diseases and inflammatory and allergic reactions as a result of a tick bite containing toxins in the saliva of the tick, which causes paralysis and lead to death, authors were able to review most of the local and international studies related to Tick's diagnosis (classification), especially tick species distribution in Iraq. Aim of this study was to create a database and put an important reference for all researchers and authors who plan to study this field more comprehensively in the future.

Nipah virus (NiV) infection - a zoonosis emerging in the 1990s - causes acute encephalitis symptoms in humans and respiratory disease in swine. NiV outbreaks have been reported in the Malay Peninsula, Bangladesh and India. In Malay Peninsula, NiV was transmitted by the fruit bat, the natural host, through swine to humans, creating a threat in both public health and animal health. In Bangladesh, NiV has been transmitted directly from fruit bats to humans and, in some cases, from humans to humans. Epidemiological conditions differ in the two regions, due in part to societal background. To prevent zoonoses - infectious diseases transmitted from a nonhuman animal to a human - such as NiV infection, measures must be taken covering two different aspects; first, against infection originating in wild animals and, second, against infection derived from domestic animals. In wild hosts, chances for the pathogen to move from hosts to humans must be minimized. With domestic animal sources, public health and animal health specialists must strengthen surveillance and detection of suspicious cases, implement common procedures for swift diagnosis, and exchange information on how to deal with outbreaks effectively.

AbstractIn many areas of Africa, recent studies highlighted the great impact of ticks on animal and human health throughout the continent. On the other hand, very limited information on the bacterial endosymbionts of the African ticks and their pattern of co-infections with other bacteria are found in literature, notwithstanding their pivotal role in tick survival and vector efficiency. Thus, we investigated the distribution of selected pathogenic and symbiotic bacteria in hard ticks collected from wild, domestic animals and from vegetation in various ecological zones in Africa and their co-occurrence in the same tick host. Overall, 339 hard ticks were morphologically identified as belonging to the genera Amblyomma, Dermacentor, Hyalomma, Haemaphysalis, Ixodes and Rhipicephalus. Molecular screening provided information on pathogens circulation in Africa, detecting spotted fever group rickettsiae, Anaplasma spp., Ehrlichia ruminantium, Borrelia garinii, Babesia spp., Theileria spp. and Coxiella burnetii. Furthermore, our work provides insights on the African scenario of tick-symbiont associations, revealing the presence of Coxiella, Francisella and Midichloria across multiple tick populations. Coxiella endosymbionts were the most prevalent microorganisms, and that with the broadest spectrum of hosts, being detected in 16 tick species. Francisella was highly prevalent among the Hyalomma species tested and correlated negatively with the presence of Coxiella, showing a potential competitive interaction. Interestingly, we detected a positive association of Francisella with Rickettsia in specimens of Hy. rufipes, suggesting a synergistic interaction between them. Finally, Midichloria was the most prevalent symbiont in Rhipicephalus sanguineus sensu lato from Egypt.

City-scale urban greening is expanding wildlife habitat in previously less hospitable urban areas. Does this transformation also prompt a reckoning with the longstanding idea that cities are places intended to satisfy primarily human needs? I pose this question in the context of one of North America's most ambitious green infrastructure programmes to manage urban runoff: Philadelphia's Green City, Clean Waters. Given that the city's green infrastructure plans have little to say about wildlife, I investigate how wild animals fit into urban greening professionals' conceptions of the urban. I argue that practitioners relate to urban wildlife via three distinctive frames: 1) animal control, 2) public health and 3) biodiversity, and explore the implications of each for peaceful human-wildlife coexistence in 'greened' cities.

Background: Since the 21st century, humans have experienced five public health emergencies: the severe acute respiratory syndrome (SARS), type A H1N1 influenza (H1N1), Middle East respiratory syndrome (MERS), Ebola virus disease (EVD), and the new coronavirus pneumonia (COVID-19). They caused a large number of casualties and a wider psychological crisis, which might cause severe consequences such as post-traumatic stress disorder and suicide. Aims: To reveal the law of formation of public psychological crisis in public health emergencies, and draw lessons from it. To provide ideas for effectively deal with these psychological crisis problems and fundamentally curbing the occurrence of public health emergencies. Method: Through the method of literature research, ‘public health incidents’, ‘psychological crisis’, ‘mental health’, ‘psychological intervention’, ‘SARS’, ‘H1N1’, ‘MERS’, ‘EVD’, and ‘COVID-19’ were used to search literatures in the databases such as PubMed, Springer, and Sciencedirect, and the literatures were summarized, sorted, and studied. Results: (1) The public health emergencies caused a universal psychological crisis. The main manifestations were depression, compulsion, despair, etc. The people involved mainly include patients, suspected isolated patients, medical staff, and the general public in the epidemic situation. (2) People’s psychological state often experienced stress stage, shock stage, acceptance, and reorganization. Only some susceptible individuals couldn’t complete effective psychological reconstruction, resulting in serious psychological disorders. Individual susceptibility is related to genetic factors, adversity, and traumatic stimuli experienced in early life. Conclusion: To reduce these psychological crisis problems, we should establish and improve the psychological crisis intervention or rescue system of public health emergencies, it was still necessary to live in harmony with nature, get rid of the inappropriate habit of preying on wild animals, in order to prevent the cross-species transmission of the virus between wild animals and humans, and to fundamentally avoid the occurrence of major infectious diseases.

Brazilian Spotted Fever

In order to obtain information on Brazilian spotted fever, a study in domestic animals was performed in the County of Pedreira, State of São Paulo, Brazil, where 17 human cases had been notified. Serum samples obtained from animals were tested by indirect immunofluorescence for detectable antibodies to spotted fever-group rickettsiae. Seropositivity was revealed in 12 (36.4%) of 33 dogs and seven (77.8%) of nine horses from the endemic area. For comparison, blood samples from dogs and horses from non endemic area were tested and four (12.9%) of 31 dogs and three (27.3%) of 11 horses were positive. The highest titers of antibodies by IFA (IgG > 1:1024) were found only in three dogs and six horses from endemic area. The results suggest that dogs as horses may serve as environmental sentinels for estabilishing the prevalence of foci of spotted fever in Brazil.

Animals were a permanent element in the landscape of medieval towns. Many residents of the then urban centres lived of animal husbandry. In addition to farm animals (e.g. pigs), they kept domestic animals (e.g. dogs and cats) as well as wild animals. The latter often sought food in garbage and suburbs. Such animals were also kept for entertainment. Authorities of Prussian towns regulated many issues related to the functioning of towns, including those concerning animal husbandry. Animals could pose a threat to the health and life of residents. They were also considered to be pests that destroy crops, orchards, and household appliances. The legislation of the period was focused on determining guilt for crimes and offenses committed by animals. Either an animal, treated as an entity responsible for the harmful act, or its owner was blamed for the misconducts. The presence of animals, especially livestock, was considered to be the cause of considerable sanitary problems in towns, mainly due to animal waste. Town authorities regulated issues concerning cattle herding and grazing. The care over the herd was entrusted to urban shepherds whose service was regulated by town legislation. The problem of the perception of animals by the society of that time was also significant. Although seemingly unwanted, they were the only source of income for many residents. For some, animals were pests, and for others, a guarantee of fragile existence. It was also a time when people began to wonder what exactly an animal is, what role it should play in human life, and how to treat it.

The deer park at Downley is one of many medieval parks known from the county of Sussex (UK), 8km north of Chichester. The park belonged to the Earls of Arundel and there is evidence of its occasional use by high-status figures, such as King Henry VIII. The park perimeter measures 6.6km and covers an area of 261.7ha. During the first season of excavation in 2014 the presence of a substantial lodge building was proven within the pale, the features associated with the lodge contained various archaeological and environmental remains. This paper focuses on the study of zooarchaeological materials recovered from the 16 trenches opened in 2014. All faunal remains were studied, revealing domestic animals such as cattle and sheep, as well as wild animals such as deer and boar. Fallow deer is the most frequent species showing a very complete body part representation, suggesting it was hunted and processed locally. Further work is carried out looking at body part representation, which is particularly important when looking at the ritualised dismemberment of hunted animals. In any hunting milieu dogs/hounds are prevalent, and are represented by some anatomical elements, but also by considerable evidence of gnawing marks on bones that were clearly humanly processed before being fed to the animals.
