The efficacy of orally administered powdered aloe juice (Aloe ferox) was evaluated against ticks on cattle and against ticks and fleas on dogs. Twelve calves were each infested over a 25-day period with approximately 4000 larvae of Rhipicephalus (Boophilus) decoloratus and allocated to 3 groups of 4 calves each. Three days after the last larval infestation and daily for 22 days thereafter, the calves in 1 group were fed 5 mg / kg body weight and those in another 25 mg / kg body weight of powdered aloe juice incorporated in game maintenance pellets, while the animals in the 3rd group received only pellets. Detached female ticks were collected daily and counted and the weights and the fertility of groups of 50 engorged female ticks collected from the animals were ascertained. The powdered aloe juice in the game maintenance pellets had no effect on the tick burdens of the calves or on the fertility of the ticks. Six dogs, in each of 2 groups, were treated daily for 15 consecutive days, commencing on Day -5 before the 1st tick infestation, with either 0.39 g or 0.74 g of powdered aloe juice, administered orally in gelatin capsules, while a 3rd group of 6 dogs served as untreated controls. All the dogs were challenged with Haemaphysalis leachi on Days 0 and +7, and with Ctenocephalides felis on Days+1and +8, and efficacy assessments were made 1 day after flea and 2 days after tick challenge, respectively. Treatment was not effective against ticks or fleas on the dogs.

The efficacy of a novel topical combination of fipronil 9.8% (w/v) and (S)-methoprene 8.8% (w/v) (Fiprofort® Plus) was tested against ticks and fleas in naturally infested dogs. A total of fifty dogs were allocated in the study with ticks infestation (n=35) and fleas infestation (n=15). On day 0, thirty-five tick and fifteen flea infested dogs received the test formulation, a combination of fipronil 9.8% (w/v) and (S)-methoprene 8.8% (w/v) spot-on solution. Ticks and flea counts were taken on days 0 (pretreatment) and 3, 7, 14, 21, 28, and 35 after treatment. Blood samples were collected for evaluation of haematological parameters on days 0 (pretreatment) and 7, 21, and 35 after treatment. All the adult ticks and fleas collected were identified asRhipicephalus sanguineusandCtenocephalides felis, respectively. The efficacy of spot-on formulation against ticks was 34.00% (day 3), 53.14% (day 7), 62.71% (day 14), 65.48% (day 21), 59.80% (day 28), and 58.82% (day 35), whereas against fleas it was 38.00% (day 3), 64.34% (day 7), 89.67% (day 14), 95.40% (day 21), 100.00% (day 28), and 100.00% (day 35). Haematological parameters for ticks and fleas infested dogs were statistically nonsignificant as compared to control. The combination of fipronil and (S)-methoprene eliminated the existing ticks and fleas infestation and prevented the dogs from flea and tick infestation for four weeks.

AbstractThe tick infestation patterns observed during 1966–73 are described for wild animals and cattle on the northern plateau of north-eastern Zambia, the eastern plateau and the intervening Luangwa valley. The seasonal periodicity of adult Amblyomma sparsum Neum., as observed on buffalo, was similar to that of A. variegatum (F.). Five major depart ures from the patterns of infestation previously found in the Central Province were observed. Boophilus decoloratus (Koch) was partially or totally replaced on cattle by B. microplus (Can.).Rhipicephalus appendiculatus Neum. although present on wild fauna in the valley, was absent from cattle on the eastern plateau. R. evertsi Neum. was absent from much but not all of the northern plateau and occurred in very low numbers only on the cattle of the eastern plateau, yet was present on the wild fauna of the Luangwa valley. Hyalomma marginaturn rufipes Koch was practically absent from cattle on the northern and the eastern plateaux and from the wild fauna, except buffalo, of the valley; H. truncatum Koch was abundant on cattle on the northern plateau and on the wild fauna of the valley, but on the eastern plateau cattle it occurred in low numbers only. A. pomposum Dön, was found on cattle in one area of the northern plateau, the only specimen of Amblyomrna on that particular herd. These anomalous findings are discussed in relation to the situation elsewhere in Zambia and in neighbouring territories.

A cross-sectional survey was conducted to determine tick infestation, and udder and teat damage in 286 lactating cows and heifers at six properties in the smallholder and commercial sectors in Gwanda district of Matabeleland South Province, Zimbabwe. Eight tick species were identified: Amblyomma hebraeum, Hyalomma truncatum, Hyalomma marginatum rufipes, Rhipicephalus evertsi evertsi, Rhipicephalus (Boophilus) decoloratus, Rhipicephalus appendiculatus, Rhipicephalus zambeziensis and Rhipicephalus simus. Overall, 81.5 % of the cattle were tick infested; prevalence of tick-infested cattle was significantly higher on communal land (93.8 %) and recently claimed land (85.1 %) than on commercial farms. The mean tick load on infested cattle on communal land was significantly higher than in the other two sectors. Although 53 % of the sampled cattle had some degree of udder and teat damage, very few farmers (2.6 %) treated their cattle for these conditions. Udder damage was ca. two times and three times, respectively, more likely to occur in cattle on communal land compared to cattle on recently claimed land and commercial farms. The occurrence of R. appendiculatus and R. zambeziensis indicate that the cattle population in the study area is at high risk of a theileriosis outbreak, a tick-borne disease that has not been reported from this area.

Across section, study of tick was conducted to identify types of tick species and determine the Prevalence of tick infestation in small ruminants in and around Dire Dawa Administrative council, Eastern Ethiopia. Collection and identification of the ticks were undertaken from November 2014 to May 2015. The overall prevalence of tick infestation in the study area was 278 (72.39% /384). All visible individual adult ticks were collected from the body of 196 goats and 188 sheep. The prevalence of tick infestation in goats and sheep was found to be 73.9% and 70.7%, respectively. In this study, eight species of ticks, which grouped under four genera, were identified. The most abundant species found in this study were Rhipicephalus pulchellus (34.1%), Amblyomma variegatum (24.5%), Rhipicephalus evertsievertsi (22.1%), Hyalomma truncatum (15.6%), Hyalomma marginatum rufipes (12.2%) and Amblyomma gemma (10.9 according to predominance. Hyalomma dromedari (4.2%) and Boophilus decoloratus was the minor species observed on both goats and sheep in the study area. The difference in prevalence of tick infestation was found statistically significant variation (P < 0.05) between the sex, age exception of Boophilus decoloratus and Hyalomma dromedari in all cases male ticks dominated females.

Ticks were collected at approximately bi-monthly intervals between June 1996 and June 1997 from crested francolins, Francolinus sephaena, and from the vegetation on a mixed cattle and wildlife farm in Limpopo Province, South Africa. The birds were infested with the immature stages of 13 tick species, of which Amblyomma hebraeum, Amblyomma marmoreum and Hyalomma marginatumrufipes were the most numerous and prevalent. Ten ixodid tick species were collected from the vegetation, of which the immature stages of Rhipicephalus appendiculatus, Rhipicephalus (Boophilus) decoloratus and Rhipicephalus evertsi evertsi were the most numerous. No adult ticks were collected from the birds and only two from the vegetation. The restricted home range of crested francolins implies that they could serve as a source of tick infestation only for other animals within the same habitat as the birds.

This study was carried out to determine the prevalence, intensity and management systems associated with tick infestation in sheep and goats from Bui and Donga-Mantung Divisions. A total of 704 animals consisting of 342 males and 362 females (463 adults and 241 young (kids/lambs) were physically examined for tick infestation, of which 383 were goats and 321 sheep aged 5 months to 7 years. Of the 704 animals examined, 651 were found positive with one or more ticks giving an overall prevalence of 92.5%. The highest prevalence was recorded in sheep (99.4%) while 86.7% was recorded in goats. There was a significant difference (p<0.05) in the prevalence and intensity of tick infestation of these ruminants in the study area. The overall intensity of infestation or tick burden was 1302 with the highest intensity observed in Boophilus geygei (416). Six species of ticks were identified which were Boophilus geygei, Boophilus annulatus, Boophilus decoloratus, Rhipicephalus sanguineus, Hyalomma truncatum and Haemophysalis laechi with a high prevalence recorded for Boophilus geygei (29.5%) and the least recorded for Haemophysalis laechi (8.4%). Adults and females were the most infested compared to young stock and male animals. Concerning the various management techniques, the prevalence of tick infestation was higher in tethered animals (97.8%), followed by free-range grazing animals (89.8%). Animals confined in paddocks had the least prevalence (71.6%). This study provides an important step to reduce animal infestation and minimize economic losses in sheep and goats by providing information that will help farmers of these areas to use strategic treatment methods and medicinal plants to reduce parasite infestations on the animals and also to practice the right traditional management techniques

The species-patterns and incidence level of ticks on the larger wild animals and on rodents were examined between 1966 and 1969 in the Southern Province, Zambia. The rodents, except for the elephant shrew, porcupine, and hare, were infrequently infested. The antelopes, except for the eland, had a mean infestation of under nine per individual, the buffalo, zebra, suids and the eland over 20. Twenty species of ticks were found on these hosts. On the ruminants Hyalomma rufipes Koch was absent, and H. truncatum Koch was the most frequent; Rhipicephalus simus Koch, R. tricuspis Dön. and R. pravus group were common. Boophilus decoloratus (Koch) was rare, R. evertsi Neum. infrequent except on zebra and lechwe, and R. appendiculatus Neum occurred on only four of the 15 ruminant species examined. Except on the elephant, Amblyomma was represented solely by A. pomposum Dön.Periodic deticking of cattle, sheep and goats yielded precise quantitative information on the seasonal changes in incidence and species-patterns of ticks. Eighteen species were found on the domestic herbivores. On cattle B. decoloratus was usually numerous and often dominant, except where controlled by dipping or spraying. Compared with infestations on wild animals, H. rufipes was frequent, A. pomposum was replaced by A. variegatum (F.), and R. evertsi and R. appendiculatus were numerous; R. simus, R. tricuspis and the R. pravus group were usually in relatively low numbers.The proportions of the different species on cattle varied widely between the stations and at different seasons. Intensive stocking, with resultant grazing down of the fieldlayer, increased the R. evertsi numbers markedly throughout the year, and depressed the numbers of Hyalomma sp., A. variegatum and of the less common Rhipicephalids during the dry season; except for A. variegatum, their numbers and those of R. appendiculatus rose, however, during the wet season to higher levels than on the less intensively stocked paddocks. Some evidence is presented that Barotse cattle are more heavily infested than Sindhi and Boran cattle.

Aloe ferox Mill. is a widely used medicinal plant in South Africa for the treatment of many ailments including constipation. The present study evaluated the toxicological effect of aqueous leaf extract of the herb at 50, 100 and 200 mg/kg body weight for 7 days on the haematological parameters as well as liver and kidney function indices in loperamide—induced constipated rats. The extract did not cause any significant (p > 0.05) effect on the kidney and liver—body weight ratio as well as the kidney function indices including serum levels of creatinine, uric acid, urea, calcium and potassium ions at all the dosages investigated. Whereas the serum levels of total protein, albumin, bilirubin and gamma glutamyl trasferase (GGT) were not affected, the elevated activities of alkaline phosphatase (ALP), alanine transaminase (ALT) and aspartate transaminase (AST) in the untreated constipated animals were normalized following treatment with extract. The data obtained with respect to the haematological analysis indicated that the extracts had no significant (p > 0.05) effect on the haematological parameters with the exception of lymphocyte count which was increased in the untreated constipated rats. This was however attenuated after administering the herb. The available evidence in this study suggests that A. ferox may be safe as an oral remedy for constipation. Generally, the effect of the extract compared favourably well with senokot, a recommended drug for the treatment of constipation.

Vacuolated cells in the liver of young rats were studied by light and electron microscopy following the administration of vitamin A (200 units per gram of body weight). Their characteristics were compared with similar cells found in untreated animals.In rats given vitamin A, cells with vacuolated cytoplasm were a prominent feature. These cells were found mostly in a perisinusoidal location, although some appeared to be in between liver cells (Fig. 1). Electron microscopy confirmed their location in Disse's space adjacent to the sinusoid and in recesses between liver cells. Some appeared to be bordering the lumen of the sinusoid, but careful observation usually revealed a tenuous endothelial process separating the vacuolated cell from the vascular space. In appropriate sections, fenestrations in the thin endothelial processes were noted (Fig. 2, arrow).

Repeated administration of methyl alcohol to Rhesus monkeys (Maccaca mulata) by intragastric tube resulted in ultrastructural abnormalities of hepatocytes, which persisted in one animal twelve weeks after discontinuation of the methyl alcohol regime. With dosages ranging between 3.0 to 6.0 gms. of methanol per kg. of body weight, the serum levels attained within a few hours averaged approximately 475 mg. per cent.
