Identification of Rickettsia species in cattle ticks in selected regions of urban Ghana.
Med Vet Entomol
January 2025
Parasitology Department, Noguchi Memorial Institute for Medical Research, University of Ghana, Accra, Ghana.
Ticks continue to invade new regions spreading pathogens of zoonotic and veterinary importance. Diverse tick species have been reported in Ghana due to the continuous trade of livestock. In this study, ticks were collected from cattle in three sites within Southern Ghana.

There is limited information on the occurrence of and ticks, as well as associated and species in Pakistan. Addressing this knowledge gap, the current study aimed at morphomolecular confirmation of these ticks and molecular assessment of associated Rickettsiales bacteria (, and spp.) in Balochistan, Pakistan.

Tick-borne pathogens are a worldwide threat to public health that can only be mitigated by knowledge on tick-host associations coupled with surveillance of their infection by pathogenic microorganisms. This information is not equally available throughout tick vector distribution range and is deficient in some geographical areas. In this study we did a molecular survey of tick-borne pathogens associated with different tick species in Morocco.

Article Synopsis
- Spatio-temporal factors are crucial in understanding the distribution and diversity of microorganisms, impacting the study of their dynamics.
- An invasive tick species in southern France was found to carry various pathogens, with an infection rate of up to 47% identified among 281 collected ticks from February to September 2022.
- The study revealed strong seasonal patterns in pathogen infection rates, particularly linked to temperature increases in summer, suggesting a relationship between temperature stress and the ticks' ability to carry and transmit pathogens.
First molecular diagnosis of the human pathogen Rickettsia raoultii and other spotted fever group rickettsiae in Sudanese ixodid ticks from domestic ruminants.

Central Laboratory, Ministry of Higher Education and Scientific Research, Khartoum, Sudan.
Article Synopsis
- Rickettsial infections are often overlooked by doctors in tropical and subtropical regions, despite new findings and reports highlighting their presence and potential risks.
- This study specifically aimed to identify and characterize spotted fever group (SFG) rickettsiae in ticks found on domestic ruminants in Khartoum State, utilizing PCR methods for genetic analysis.
- The results showed that SFG rickettsiae were present in the examined ticks, identifying four different species, which suggests a risk for human infections, especially in cases of fever with no known cause.
