“…Since the turn of the nineteenth century when the first description of a tick-transmitted infection was made (Smith and Kilborne 1893 ), many tick species are now known reservoirs and vectors of a multitude of pathogens that cause significant morbidity and mortality in both humans and animals. Some of the diseases that have since been described such as East Coast fever and Crimean-Congo hemorrhagic fever are challenging public health, veterinary, and socio-economic threats due to their increasing occurrence, pathogenicity, and economic impact (Adams et al 2016 ; Kuehn 2019 ; Wesołowski et al 2014 ).…”

In Uganda, the role of ticks in zoonotic disease transmission is not well described, partly, due to limited available information on tick diversity. This study aimed to identify the tick species that infest cattle. Between September and November 2017, ticks ( n = 4362) were collected from 5 districts across Uganda (Kasese, Hoima, Gulu, Soroti, and Moroto) and identified morphologically at Uganda Virus Research Institute. Morphological and genetic validation was performed in Germany on representative identified specimens and on all unidentified ticks. Ticks were belonging to 15 species: 8 Rhipicephalus species ( Rhipicephalus appendiculatus , Rhipicephalus evertsi evertsi , Rhipicephalus microplus , Rhipicephalus decoloratus , Rhipicephalus afranicus , Rhipicephalus pulchellus , Rhipicephalus simus , and Rhipicephalus sanguineus tropical lineage); 5 Amblyomma species ( Amblyomma lepidum , Amblyomma variegatum , Amblyomma cohaerens , Amblyomma gemma , and Amblyomma paulopunctatum ); and 2 Hyalomma species ( Hyalomma rufipes and Hyalomma truncatum ). The most common species were R. appendiculatus (51.8%), A. lepidum (21.0%), A. variegatum (14.3%), R. evertsi evertsi (8.2%), and R. decoloratus (2.4%) . R. afranicus is a new species recently described in South Africa and we report its presence in Uganda for the first time. The sequences of R. afranicus were 2.4% divergent from those obtained in Southern Africa. We confirm the presence of the invasive R. microplus in two districts (Soroti and Gulu). Species diversity was highest in Moroto district ( p = 0.004) and geographical predominance by specific ticks was observed ( p = 0.001). The study expands the knowledge on tick fauna in Uganda and demonstrates that multiple tick species with potential to transmit several tick-borne diseases including zoonotic pathogens are infesting cattle.

“…Tick-borne diseases (TBD) are a public health problem in the world [1]. Ticks harbor a great diversity of microorganisms, some of which are pathogenic to humans and other mammals [2]. Ticks are obligate hematophagous ectoparasites associated with the transmission of viruses, bacteria, and protozoa, which affect both human and animal health [3,4].…”

Assessment of bacterial diversity of Rhipicephalus microplus ticks from two livestock agroecosystems in Antioquia, Colombia

et al. 2020

Rhipicephalus microplus is recognized as a tick species highly prevalent in cattle, with a wide pantropical distribution that seems to continue spreading geographically. However, its role as a biological vector has been scarcely studied in the livestock context. In this study, a 16S rRNA next-generation sequencing analysis was used to determine bacterial diversity in salivary glands and gut of R. microplus from two contrasting livestock agroecosystems in Antioquia, Colombia. Both the culture-independent approach (CI) and the culture-dependent (CD) approach were complementarily adopted in this study. A total of 341 unique OTUs were assigned, the richness showed to be higher in the Northern than in the Middle Magdalena region, and a high diversity was found at the phylum and genus levels in the samples obtained. With the CI approach, Proteobacteria, Bacteroidetes, Firmicutes, and Actinobacteria were the most common phylum of bacteria regardless of the organ, or geographic origin of the specimens analyzed. While the relative abundance of bacteria at a phylum level with the CD approach varied between analyzed samples, the data obtained suggest that a high diversity of species of bacteria occurs in R. microplus from both livestock agroecosystems. Bacterial genera such as Anaplasma, Coxiella, and Ehrlichia, recognized for their implications in tick-borne diseases, were also detected, together with endosymbionts such as Lysinibacillus, previously reported as a potential tool for biological control. This information is useful to deepen the knowledge about microbial diversity regarding the relations between endosymbionts and pathogens and could facilitate the future development of epidemiological surveillance in livestock systems.

“…Patient counseling on the signs and symptoms of early Lyme disease should be provided. 9 Chemoprophylaxis can be considered, with a single dose of doxycycline (200 mg), for patients who have had a tick attached to them for more than 24 hours. 4 In Canada, Lyme-endemic areas are found in suitable woodland habitats for ticks, generally the southern parts of each province, with a flare-up of cases from late spring to early fall.…”

A 42-year-old woman presented to the emergency department (ED) with acute onset periumbilical pain and erythema, which started that morning. She felt nauseated but denied vomiting. Her bowel movements were regular and non-bloody. She did not have a fever. She had no significant prior medical history, no recent trauma, and had no previous surgeries.In the ED, she appeared uncomfortable from pain but was not in acute distress. Vital signs upon initial presentation included a heart rate of 120 beats/min, a blood pressure of 145/111 mm Hg, respiratory rate of 16 breaths/min, temperature of 36.8°C (98.2°F), and an oxygen saturation of 99% on room air. Her vital signs two hours later after a fluid challenge and analgesics had improved to a heart rate of 74 beats/min and blood pressure of 132/83 mm Hg, and the remaining vitals were the same. Her abdomen demonstrated periumbilical erythema, with a central clearing; the area was tender to palpation, and warm to touch. Images of her periumbilical region are shown in Figure 1. The rest of the abdomen was soft and non-tender, with no masses or organomegaly. An ED ultrasound was performed to assess for possible subcutaneous abscess, which was not seen. Cardiovascular and respiratory exams were unremarkable.
