Summary: Ticks in Africa remain a major obstacle in the livestock industry due to tick-borne pathogens. This study conducted a systematic review and meta-analysis to examine the distribution and prevalence of these pathogens in African ticks. The highest prevalence was found for Rickettsia spp., R. africae, R. conorii, A. marginale, E. ruminantium, and E. canis. The prevalence of C. burnetii was low, but higher for Coxiella spp. and Coxiella-like endosymbionts. The study also identified the effect of tick genera, tick species, country, and other variables on the epidemiology of these pathogens in ticks.

Summary: This study aimed to describe the occurrence of ticks and tick-borne pathogens in different land use types in southern Africa. Through molecular techniques, 1716 ticks were screened for infection, revealing multiple pathogen species across seven tick species collected. The findings suggest that tick species and the pathogens they carry may vary according to land use, highlighting the importance of comprehensive surveillance in understanding the diversity and ecology of tick-borne pathogens.

Summary: The study revealed a high diversity of ticks and tick-borne pathogens associated with camels and co-grazing sheep in northern Kenya. In addition, the findings suggest that camels and/or the ticks infesting them serve as reservoirs for zoonotic diseases, posing a public health threat to pastoralist communities.

Summary: There is no updated information on the spread of Rickettsiales in Italy. A study identified 36 species of microorganisms belonging to Rickettsiales, with certain species found in human tissues. Pathologies caused by microorganisms transmissible by bloodsucking arthropods in humans are not well characterized.

Summary: Tickborne intracellular bacterial pathogens such as Anaplasma, Coxiella burnetti, Ehrlichia, and Rickettsia were detected in Haemaphysalis flava ticks from hedgehogs in Central China. The prevalence of these pathogens varied among different developmental stages of ticks, with the highest infection rate observed in dead engorged females.

Summary: The ability to genetically manipulate pathogens is crucial for understanding host-pathogen interactions and developing treatment strategies. Methods for modifying obligate intracellular bacterial pathogens have been limited, but significant progress has been made in the past few decades. This review highlights recent genetic achievements and developments for several important pathogens and discusses future research directions. Overall, the future looks promising for unraveling the molecular pathogenic mechanisms of these significant pathogens.

Summary: Tick-borne pathogens were investigated in cattle in the Rabat-Sale-Kenitra region of Morocco, revealing a high prevalence and diversity of tick species, with Anaplasma/Ehrlichia spp. having the highest infection rate. Risk factors for pathogen abundance included crossbreeds, females, older age, and high tick infestation. Locations with the highest prevalence of tick-borne pathogens were Jorf El Melha, Sidi Yahya Zaer, Ait Ichou, and Arbaoua.

Summary: This study describes the presentation, clinical signs, parasitemia levels, laboratory findings and treatment of dogs infected with B. negevi. Treatment with imidocarb dipropionate was helpful for recovery from clinical disease but did not facilitate parasite elimination, and it is therefore recommended to treat canine B. negevi infection with the combination of atovaquone and azithromycin.

Summary: In many parts of the northern hemisphere, different species of deer, small mammals, and birds coexist and their composition can strongly influence the outbreak potential of tick-borne pathogens. This study investigates how the abundance and composition of vertebrate communities affect the basic reproduction number R0 of tick-borne pathogens, and shows that species composition plays a substantial role in the outbreak potential of tick-borne diseases.

Summary: Published data on tick-borne pathogens in camels worldwide have been collected, providing an overview of their global prevalence and species diversity. Evidence of natural infection of camels with certain tick-borne pathogens is limited, particularly because most of the camels were considered healthy at the time of sampling. More research is needed to understand the role of camels in maintaining and transmitting these pathogens.
