In vitro evaluation of acaricidal activity of eugenol and benzaldehyde against Rhipicephalus annulatus.

Economic importance of ticks for both humans and animals is significant primarily because of their involvement in disease transmission. The continuous use of synthetic chemical acaricides on animals and/or in the environment has resulted in the emergence of resistant tick populations. Consequently, there is a compelling need to explore newer natural alternatives that can address their adverse effects effectively.

Morphological and molecular characterization of Rhipicephalus microplus and Rhipicephalus annulatus from selected states of southern India.

Ticks of the genus Rhipicephalus infesting cattle are the primary animal pests responsible for the annual economic loss of billions of dollars. Due to the morphological resemblance among the members of the Rhipicephalus (Boophilus) genus, species identification is very difficult. In this study, the adult R.

Molecular detection of pathogens in the ova and unfed larvae of Rhipicephalus annulatus and Haemaphysalis bispinosa ticks infesting domestic cattle of south India.

This study aimed to investigate the presence of pathogens in the engorged ticks infesting domestic cattle, their ova, and unfed larvae. The engorged female ticks infesting domestic cattle of Wayanad district of Kerala, south India were collected and kept for oviposition. The dead females after the complete oviposition, their egg masses, and unfed larvae were screened for the presence of various pathogens by specific PCRs.

Molecular Characterization of Hemoparasites and Hemoplasmas Infecting Domestic Cats of Southern India.

In the present study, 111 blood samples were collected from apparently healthy cats belonging to four districts of Kerala, southern India, and they were investigated for the presence of hemoparasites and hemoplasmas by light microscopic examination and polymerase chain reaction (PCR). The microscopic examination of the Giemsa-stained blood smears did not reveal any parasites/organisms. However, PCR followed by nucleotide sequencing could detect 10 (9.

Ticks and accompanying pathogens of domestic and wild animals of Kerala, South India.

The objective of the present study was to detect the chosen nucleotide DNA or RNA sequences of the pathogens in ticks of domestic and wild animals of Kerala, South India based on molecular techniques. Among 602 ticks collected, 413 were from bovines (cattle and buffalo), 26 from goats, 101 from dogs and 62 from wild animals. Amblyomma integrum, Am.

Molecular characterization of South Indian field isolates of bovine Babesia spp. and Anaplasma spp.

Ticks and tick-borne diseases (TTBDs) are considered major causes of economic loss in the livestock sector which incur an annual control cost estimated at US$ 498.7 million in India. Among these diseases, babesiosis, theileriosis and anaplasmosis are listed among the top ten livestock diseases in India and cause significant mortality and morbidity among cattle.
