Test Formulation

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.

Ticks are blood-feeding obligate ectoparasites that belong to order Arachnida with three main families (Ixodidae, Argasidae, and Nuttalleillidae). Ticks transmit viral, bacterial, and zoonotic diseases in humans, and animals (wild and domestic). Ticks directly and indirectly affect the livestock industry which plays an important role in the rural economy of Pakistan. These are the main source of income and a source of food for poor people. The current study was conducted to identify the tick species infesting livestock in Dera Ismail Khan Pakistan. For this purpose, different farms were randomly visited and 130 ticks were collected from 200 scanned animals.  The collected ticks were identified to species level using morphological keys. In the current study, four tick species were identified as Rhipicephalus sanguineus, Hyalomma marginatum, Hyalomma anatolicum, and Dermacentor marginatus were identified. The most dominant species were Hy. anatolicum (35.39%) followed by R. sanguineus (30.00%), Hy. marginatum (23.85%) and D. marginatus (10.77%). Hy. anatolicum was the predominant tick species and accounted for 35.39% of the ticks. Tick infestation was highest in buffaloes followed by cows, sheep, and goats. Tail and ear were the most preferable sites for tick infestation than other body parts.

Global Threat

Tick infestation in humans and animals represents a global threat for different tick-borne diseases. In the present study, the ticks from the Gwalior region of India have been mapped to create a database of tick diversity. We explored 773 ticks collected from domestic animals and vegetation in Gwalior. Animals were screened visually, and ticks were collected manually, whereas the flag-drag method was used to collect ticks from the vegetation. The 16S rRNA and cytochrome oxidase I (COI) genes of tick samples were amplified and purified for sequencing and respective phylogenetic trees were constructed. The ticks were morphologically identified using taxonomical keys, revealing the presence of five genera in the region: Hyalomma, Haemaphysalis, Rhipicephalus, Boophilus, and Nosomma. Hyalomma spp. (Hy. annatolicum and Hy. marginatum) were the most abundant accounting for 69.598% of the total sample, followed by Rhipicephalus sanguineus (17.335%), Rhipicephalus microplus (7.115%), Haemaphysalis sp. (5.692%), and Nosomma monstrotum (0.258%). The tick sequences were submitted to the GenBank database. Phylogenetic analysis confirmed the morphological identification at the species level. The combination of molecular and morphological analyses of the ticks supported the result obtained with each method, thus providing more reliable estimates for continued surveillance studies.

Abstract BackgroundHaematological examination is an important diagnostic tool in the assessment of pig health status. The present study aimed to assess haematological parameters in pigs of different age categories from six farrow-to-finish farms differing in herd health status. The following pig categories were included: 5 age groups of growers (5, 7, 9–10, 11 and 12–13 weeks-old), fatteners and breeding pregnant sows. Individual blood samples for determining complete blood count and white blood cell differential count were taken and group samples of oral fluid and faeces were collected from each animal category in each of the six farms and tested for the detection of Porcine Circovirus Type 2 (PCV2), Porcine Reproductive and Respiratory Virus (PRRSV), and Hepatitis E Virus (HEV) using PCR, RT-PCR, and qRT-PCR protocols. Individual blood samples were analysed using an automated laser-based haematology analyser. The following haematological parameters were reported: white blood cell count (WBC), red blood cell count (RBC), haemoglobin concentration (Hb), haematocrit (Hct), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), platelet count (PLT), and percentage and number of neutrophils, lymphocytes, monocytes, eosinophils, basophils, and "large unstained cells" - LUCs. ResultsOn farms free of PRRSV, PCV2 and HEV, age had significant effect on the following parameters: WBC, Hb, MCH, MCHC, PLT, percentage of neutrophils, lymphocytes and eosinophils and absolute numbers of neutrophils, lymphocytes, monocytes, basophils and LUCs. On farms with PRRS, PCV2 and/or HEV, age significantly affected all observed blood parameters except the percentage of LUCs. The percentages of lymphocytes, MCV and Hct were significantly lower by PRRSV while WBC, PLT, percentage and absolute number of neutrophils, basophils and LUCs increased. Significantly lower percentages of lymphocytes and increased percentages and absolute numbers of neutrophils, eosinophils and basophils were caused by PCV2 presence. Significantly lower percentage of lymphocytes and MCV and increased RBC, Hb, percentage and number of basophils and percentage of neutrophils were caused by HEV. Conclusions Alterations of haematological parameters reflected the health status of pigs of different categories on infected and on non-infected farms. Age-related changes in haematological parameters occurred in clinically healthy and in infected pigs.

Three Phases

ABSTRACT Doxycycline is the treatment of choice for canine monocytic ehrlichiosis (CME), a well-characterized disease and valuable model for tick-borne zoonoses. Conflicting reports of clearance of Ehrlichia canis after treatment with doxycycline suggested that the disease phase during which treatment is initiated influences outcomes of these treatments. The purpose of this study was to evaluate the efficacy of a 28-day doxycycline regimen for clearance of experimental E. canis infections from dogs treated during three phases of the disease. Ten dogs were inoculated with blood from E. canis carriers and treated with doxycycline during acute, subclinical, or chronic phases of CME. Daily rectal temperatures and semiweekly blood samples were monitored from each dog, and Rhipicephalus sanguineus ticks were acquisition fed on each dog for xenodiagnosis. Blood collected from dogs treated during acute or subclinical CME became PCR negative for E. canis as clinical parameters improved, but blood samples collected from dogs treated during chronic CME remained intermittently PCR positive. R. sanguineus ticks fed on dogs after doxycycline treatments became PCR positive for E. canis, regardless of when treatment was initiated. However, fewer ticks became PCR positive after feeding on two persistently infected dogs treated with doxycycline followed by rifampin, suggesting that antibiotic therapy can reduce tick acquisition of E. canis.
