Expansion of Tick-Borne Rickettsioses in the World
microorganisms Review Expansion of Tick-Borne Rickettsioses in the World Mariusz Piotrowski * and Anna Rymaszewska Institute of Biology, University of Szczecin, 70-453 Szczecin, Poland; [email protected] * Correspondence: [email protected] Received: 24 September 2020; Accepted: 25 November 2020; Published: 30 November 2020 Abstract: Tick-borne rickettsioses are caused by obligate intracellular bacteria belonging to the spotted fever group of the genus Rickettsia. These infections are among the oldest known diseases transmitted by vectors. In the last three decades there has been a rapid increase in the recognition of this disease complex. This unusual expansion of information was mainly caused by the development of molecular diagnostic techniques that have facilitated the identification of new and previously recognized rickettsiae. A lot of currently known bacteria of the genus Rickettsia have been considered nonpathogenic for years, and moreover, many new species have been identified with unknown pathogenicity. The genus Rickettsia is distributed all over the world. Many Rickettsia species are present on several continents. The geographical distribution of rickettsiae is related to their vectors. New cases of rickettsioses and new locations, where the presence of these bacteria is recognized, are still being identified. The variety and rapid evolution of the distribution and density of ticks and diseases which they transmit shows us the scale of the problem. This review article presents a comparison of the current understanding of the geographic distribution of pathogenic Rickettsia species to that of the beginning of the century. Keywords: Tick-borne rickettsioses; Tick-borne diseases; Rickettsiales 1. Introduction Tick-borne rickettsioses are caused by obligate intracellular Gram-negative bacteria belonging to the spotted fever group (SFG) of the genus Rickettsia. -
Don't Let Sleeping Dogs Lie: Unravelling the Identity and Taxonomy of Babesia Canis, Babesia Rossi and Babesia Vogeli

Penzhorn1,2* Abstract For most of the 20th century the causative agent of canine babesiosis, wherever it occurred in the world, was com- monly referred to as Babesia canis. Early research, from the 1890s to the 1930s, had shown that there were three distinctly diferent vector-specifc parasite entities occurring in specifc geographical regions, that host response to infection ranged from subclinical to acute, and that immunity to one stock of the parasite did not necessarily protect against infection with other stocks. This substantial body of knowledge was overlooked or ignored for 50 years. In this review the frst records and descriptions of the disease in four geographical regions were traced: sub-Saharan Africa, Europe, North Africa and Asia. Research leading to identifcation of the specifc tick vector species involved is docu- mented. Evidence is given of the growing realisation that there were substantial biological diferences between stocks originating from diferent geographical regions. Etymological provenance for Babesia vogeli is proposed.

E-mail: [email protected], Telephone: +2348053349321; +2347033369355 ABSTRACT Oviposition patterns of engorged adult females of dog ticks: Rhipicephalus sanguineus and Haemaphysalis leachi leachi were studied at various photoperiods under constant temperature and relative humidity in the laboratory. The ticks were subjected to six different photoperiods throughout the period of oviposition and eggs were removed six hours. There were no significant differences in the mean pre-oviposition period, duration of oviposition and the number of eggs laid by R. sanguineus and H. leachi leachi in all the photo- periodic conditions. The pre-oviposition periods of R. sanguineus and H. leachi leachi sampled every six hours (disturbed group) were significantly lower (p<0.05) than those sampled every 24 hours (undisturbed group). No significant differences existed in the duration of oviposition of the disturbed (8.0±1.78 and 8.0 ±1.11) and undisturbed (8.6±1.79 and 8.9±0.23) groups. Also no significant difference occurred in the number of eggs laid per mg body weight of the disturbed and undisturbed groups for R. sanguineus and H. leachi leachi respectively. Oviposition started during the scotophase in all the experimental ticks and egg collection started at 24 hours. -

Some morphological characterizations about the R. microplus species in Cuba have been published, however, molecular studies are lacking. Molecular phylogenetic analyses have revealed a common ancestor for R. annulatus, R. australis and three clades of R. microplus within the Boophilus subgenus. These ve clades were grouped in a complex named R. microplus. The present study aimed the accurate taxonomic classication of R.
