Biological Performance

Dipping trials with two supelcooled melt formulations of DDT, in which the DDT concentrations were raised progressively to four times the usual strength, showed that whilst more DDT was deposited both on the hair of calves and on bush ticks (Haemaphysalis bispinosa Neumann) as the DDT concentration was increased and the dip aged, the toxicity to ticks of both formulations increased only during the early stages of each trial. Clearly the size and shape of the DDT crystals which developed in both dips and the degree of crystal aggregation were important factors which influenced the deposition of DDT and its toxicity. Of the forms of DDT present, the toxicity is attributed mainly to microcrystals of colloidal dimensions. Additions of formulation would serve to maintain but not increase the concentration of these microcrystals. Differences in performance of the dips is ascribed to the composition of the soaps (i.e. surface active agents) in the formulations. The experiments emphasize the importance of the nature of the deposit, and indicate that increases in dip concentration will not necessarily give better biological performance.

Tick cell cultures have been widely used as an important tool for the study of tick-associated microorganisms, specifically for medically important bacteria or viruses that may be difficult to isolate or culture in axenic conditions. In this study, primary embryonic tick cell cultures were initiated separately from each of the egg batches laid by 10 female ticks belonging to the hard tick genus Haemaphysalis. All cultures were maintained at 28°C. After 10 months, 4 healthy cultures were identified with the potential for developing into continuous tick cell lines. These cultures comprise large cells predominantly forming floating cell clumps with multicellular vesicles, which are morphologically similar to cell lines derived from the soft tick Ornithodoros moubata. Subculture has not yet been performed due to the low cell density at the time of writing. Amplification and sequencing of a fragment of the 16S rRNA gene from DNA extracted from the parent ticks showed 99%-100% similarity to published sequences of Haemaphysalis bispinosa. This is the first report of the initiation of embryonic cell cultures from Haemaphysalis ticks found in Malaysia. Such tick cell cultures will be useful for studies of tick-borne pathogens in this region, where recent studies have shown that Haemaphysalis ticks are highly represented and harbor medically important bacteria.

Controlled Conditions

Haemaphysalis bispinosa has been shown to reproduce by obligatory parthenogenesis. Male ticks were found to be scarce in both experimental and natural infestations, occurring in the ratio of one to approximately every 400 females. Dissections of five males showed that these produced no spermatozoa, irrespective of whether they were fed or not. Rates of development of the non-parasitic stages under controlled conditions are recorded.

A study was carried out on 60 cattle and 34 (56.66%) were found infested with ticks and lice. Mean parasitic burden was 2.26 ± 0.37 per square inches in cattle. Two species of arachnids, Haemaphysalis bispinosa (31.66%) and Rhipicephalus sanguineus (28.33%) lice, Linognathus vituli (23.33%) were identified. Mean parasitic burden was high in case of R. sanguineus (4.33 ± 0.48) followed by H. bispinosa (2.89 ± 0.62) and least in L. vituli (1.28 ± 0.16). Prevalence of ectoparasites were relatively higher in young animals aged > 1 - 3 year (66.66%) followed by in calf aged ± 1 year (50%) and lowest in adult aged > 3 year (44.44%) in cattle. The mean parasitic burden was higher in case of young (2.8±0.60) followed by adults (1.75 ± 0. 41) and calves (1.5 ± 0.34). Infestation was higher in female (64.10%) than the male (42.85%). Prevalence of ectoparasites were relatively higher in summer (75%) followed by in winter (55%) and lowest in rainy season (40%). The mean parasitic burden was highest in summer (1.93 ± 0.64) followed by in winter (1.72 ± 0.54) and lowest in rainy season (1.5 ± 0.50). Bangladesh J. Zool. 46(2): 137-145, 2018

Transstadial transmission of Theileria annulata with Hyalomma anatolicum anatolicum, H. dromedarii and H. marginatum isaaci, and Haemaphysalis bispinosa, Rhipicephalus haemaphysaloides haema-physaloides and Boophilus microplus was determined.It was found that the infection was successfully transmitted by H. a. anatolicum from larva to nymph and nymph to adult in all attempts. When larvae were fed on an infected calf the succeeding adults transmitted the infection when the intervening nymphs fed on a rabbit (nonsusceptible host) but not when fed on a calf (susceptible host). Infective adult ticks transmitted the parasite during the first 24 h of feeding on a calf. When the feeding was interrupted after 24 h, and the tick transferred to another calf, the infection was transmitted to the latter as well.H. dromedarii successfully transmitted the infection from larva to nymph and from nymph to adult.Larvae of H. marginatum isaaci did not feed on calves but the infection was successfully transmitted from nymph to adult.Haemaphysalis bispinosa, Rhipicephalus h. haemaphysaloides and Boophilus microplus did not transmit Th. annulata from larva to nymph to adult.

A cross section survey was carried out during the period from April to September, 2009 in different villages of Bogra district in Bangladesh to know the prevalence of ticks and lice in relation to age, sex, breed and body condition of cattle.  Out of 250 randomly selected cattle, 142 (56.8%) were found infested with one or more species of ticks and lice.  Among ticks, the prevalence rate was highest in case of Haemaphysalis bispinosa (31.2%) followed by Rhipicephalus sanguineus (29.2%), Boophilus microplus (27.2%) and only one species of louse Haematopinus eurysternus (23.2%). The range of parasitic burden was 1 to 16 per four square inch of heavily infested area of affected cattle. Mean parasitic burden was high in case of Haematopinus eurysternus (4.71 ± 0.35) followed by Rhipicephalus sanguineus (4.56 ± 0.29), Boophilus microplus (4.25±0.15) and Haemaphyalis bispinosa (2.85 ± 0.17). Results indicated that prevalence was significantly (P<0.01) higher in young cattle aged >1-3 years (68.0%) than calves aged ?1 year age (46.15%) and adults aged >3 years (45.2%). Infestation of tick and lice was significantly higher (P<0.05) in female (64.63%) than the male (41.86%). Infestation was more prevalent in local (72.32%) breed than the crossbred (44.2%) cattle. Cattle with poor body condition were found to be significantly (P<0.01) more vulnerable to such parasitic infestation than of cattle having normal body condition. It is concluded that tick and lice prevalence is alarming and threatening to the cattle population and host determinants play a vital role in the frequent occurrence of these ectoparasites in the study area.DOI: http://dx.doi.org/10.3329/pa.v22i1-2.16468 Progress.

Background: Ecto-parasites namely ticks, lice and flea are important due to their blood sucking habit, skin damage and acting as vectors for various disease pathogens in both livestock and humans. The aims of this study were to estimate the prevalence and identify potential factors associated with ecto-parasitic infestations at Mymensingh sadar, Mymensingh. Methods: A cross-sectional study was undertaken during July 2019 to June 2020. The data on risk factors was recorded using a questionnaire. Ecto-parasites were collected from randomly selected 173 goats and examined by preparing permanent slides. The potential factors were identified by univariable analysis. Main results: The overall prevalence of ectoparasitic infestation was 60.1% (104/173). The identified ecto-parasites were Damalinia caprae (83, 47.9%), Linognathus stenopsis (42, 24.3%), Haemaphysalis bispinosa (36, 20.8%) and Ctenocephalides canis (16, 9.3%). Female (70.7%) goats were 2.9 times more prone to ecto-parasitic infestations than male goats (48.2%). Significantly highest infestations was recorded in adult goats (72.7%), followed by the young goats (52.7%) and the lowest in kids (46.3%). Also, prevalence was significantly (p< 0.001) higher in poor conditioned (76.4%) and anemic (72.9%) goats than that of good conditioned (34.3%) and non-anemic (44.2%) goats, respectively. Furthermore, acaricides /insecticides use in goats greatly influenced the prevalence of ecto-parasitic infestations. Prevalence was higher in those goats that never treated with acaricides and/or insecticides (70.78%) than those goats regularly treated with acaricides/insecticides (27.91%). Conclusions: A very high prevalence of ecto-parasitic infestation was recorded in goats of Mymensingh district. Farmers awareness should be increased to control ectoparasitic infestations especially in female, adult and goats with poor body condition.
