“…Similar findings were accorded with research findings from the African countries of Ethiopia and Nigeria, and the Indian state of West Bengal (Bangladesh) [ 30 , 31 , 32 , 33 ]. However, several studies also reported contrary statements to our research findings, that insufficient and weakened immune systems in young and elderly livestock were the causes of the increased tick infestation in the young calves and elderly livestock as they were the least cared for, in contrast to the productive adult livestock, which receive the best management treatment [ 34 ]. As a result, they could serve as a holding area for persistent environmental tick infestation.…”

“…As a result, they could serve as a holding area for persistent environmental tick infestation. Furthermore, our study indicated that the most common tick predilection sites on livestock are the neck and groove regions; however, in another study ([ 34 ]), it was revealed that the external genitalia, udder, and perineum were the most infected parts during tick infestation. Our criteria indicated that 52% of the respondents knew enough about ticks to understand their potential role as disease vectors.…”

A Participatory Approach in Assessing the Knowledge, Attitude, and Practices (KAP) of Stakeholders and Livestock Owners about Ticks and Tick-Borne Diseases from Sindh, Pakistan

Ticks and tick-borne diseases (TTBDs) are responsible for significant losses in terms of treatment costs, decreased productivity (such as milk and meat), reduced reproductive ability, and financial crisis to livestock owners. In Pakistan, it is crucial to periodically assess the risk of TTBDs and ecological factors, potential causes of acaricidal resistance in tick fauna, and the intensive increase in the spread of TTBDs. Participatory epidemiological approaches are key to assessing the livestock owners’ and stakeholders’ knowledge, attitude, and practices (KAP) about TTBDs. The current study determined the KAP about ticks and tick-borne diseases of respondents from Sindh, Pakistan. A total of 240 respondents were interviewed from different ecological zones: among them, 42.5% (n = 102) of the respondents practiced the manual removal of ticks from animals, while acaricide usage was indicated by 137 respondents (57.0%) as occurring sometimes, 50 (20.8%) monthly, 41 (17.0%) fortnightly, and 12 (5%) weekly, during the peak infestation season. Ticks were 2.6 times [OR = 2.5 (95% Cl = 1.47–4.06)] and viruses were 1.89 times [OR = 188 (95% Cl = 1.09–2.9)] more likely to cause the development of disease in animals than any other pathogen. Despite the appropriate usage of acaricides, the knowledge of participants was inadequate. The findings of this study emphasize the need to take into account identified knowledge gaps and to take the initiative in carrying out appropriate education activities and extension programs to enhance the adoption of effective tick prevention and control strategies.

“…The prevalence of theileriosis caused by annulata pathogens has previously been reported in different countries; a prevalence rate of approximately 30% has recently been reported in Portugal [ 60 ], about 76.87% has been reported in Pakistan [ 61 ], 23% in India [ 62 ], 64% in Egypt [ 63 ], 18% in China [ 64 ], and 24% in Spain [ 65 ]. There is a dearth of information on the occurrence of T. annulata in South Africa, except for the report of [ 66 ], who reported its occurrence in the country.…”

Genomic Profiling for Piroplasms in Feeding Ixodid Ticks in the Eastern Cape, South Africa

et al. 2020

Importation of tick-infected animals and the uncontrollable migration of birds and wild animals across borders can lead to geographical expansion and redistribution of ticks and pathogen vectors, thus leading to the emergence and re-emergence of tick-borne diseases in humans and animals. Comparatively, little is known about the occurrence of piroplasms in ixodid ticks in the Eastern Cape, South Africa, thus necessitating this study, which is aimed at detecting piroplasms (Theileria and Babesia) from feeding tick samples collected from cattle, sheep, and goats in selected sites in the Eastern Cape, South Africa. A total of 1200 feeding ixodid ticks collected from farm animals at selected homesteads were first subjected to molecular identification using mitochondrial 12S ribosomal RNA (rRNA) gene by PCR and were further tested for the presence of piroplasms through amplification of the 18S rRNA gene via nested-PCR followed by sequencing of the PCR products. The results indicated that 853 (71.1%) corresponded to the genus Rhipicephalus, 335 (27.9%) corresponded to genus Amblyomma, and 12 (1%) corresponded to genus Haemaphysalis. Amblyomma hebraeum and Rhipicephalus appendiculatus were the most common identified ticks from this study. The 18S rRNA nested-PCR revealed that 44 (3.7%) samples were confirmed positive for Theileria. A homology search for the generated sequences revealed a high percentage identity of 98–98.9% similarity to T. buffeli, T. orientalis, and T. sergenti in the GenBank. Based on the results obtained herein, we conclude that there is a big diversity of Theileria species; therefore, we suggest that this research should cover more geographical areas in order to reveal the true prevalence of this pathogen in the studied area because this will be a great step in the possible prevention of an outbreak that could have devastating effects on livestock production and human health in both the studied areas and South Africa at large.

Background: Theileria spp. were targeted for detection and differentiation from clinical samples using PCR in the current investigation and the diagnostic sensitivity of this method was evaluated in comparison to microscopic observations. The clinical characteristics of bovine tropical theileriosis as clinical markers were also analysed based on the PCR data. Methods: On the basis of clinical evaluation and microscopic inspection of blood smears, 200 blood samples from cattle suspected of having theileriosis were examined. To confirm the disease, the PCR method was employed by using 18S rRNA and Cyto b1 gene to confirm Theileria spp. and Theileria annulata respectively in clinical samples. Result: The results showed that microscopic examination detected 65/200 (32.50%), whereas, the PCR assay identified 120/200 (60.00%) for Theileria spp. Of the total 200 samples studied, 77 (38.50.3%) were positive for T. annulata specific PCR. Based on PCR confirmation of T. annulata infection in cattle, the predominant clinical signs were pyrexia, ticks’ infestations, anorexia, enlargement of lymph node, pale mucous membrane, lacrimation, coughing, drop in milk production and emaciation. The other clinical signs were observed as icterus, nasal discharge, salivation, melena and exophthalmia.
