The efficacy of a beef-based, chewable formulation of ivermectin against a mixed infection of Ancylostoma braziliense and A tubaeforme was determined in cats. Ivermectin administered orally at approximately 24 microgram/kg of body weight was 92.8% effective against adult A braziliense and 90.7% effective against adult A tubaeforme. The number of eggs per gram of feces had decreased 98.1% by 7 days after treatment. Clinical signs of hookworm disease also decreased after treatment. Location of adult parasites within the small intestine, percentage of infecting larvae that developed to the adult stage, and egg size in cats with infections of A braziliense and A tubaeforme were similar to those reported for cats with separate infections of either species.

Stray dogs are carriers of several zoonotic diseases such as leishmaniasis and canine monocytic ehrlichiosis (CME) as a result of poor nutrition, low hygienic conditions and lack of veterinary care. Thus, the Veterinary Research Institute (VRI) conducted a survey to determine the parasite pathogens such as blood protozoans, gastrointestinal parasites and ectoparasites in stray dogs with the collaboration of the Kuala Lumpur City Council Pest Control Unit. Skin, organ, faecal and blood samples were analysed and results indicate that Babesia canis, Babesia gibsoni, Ehrlichia canis, Hepatozoon canis and microfilaria of Dirofilaria immittis are the common parasites species found in the blood and organ samples in 2014. The faecal floatation technique showed the presence ofhelminth ova such as Trichuris, Ancylostoma and Toxocara species. All skin samples were positive for Rhipicephalus sanguineus ticks. As strays are closely linked to human habitats such as market and housing areas, it is vital that stray population control is strategically implemented to safeguard these common zoonotic infections from spreading to humans.

Eighteen dogs with naturally acquired helminth infections were used to evaluate the efficacy of nitroscanate against Ancylostoma caninum, Dipylidium caninum, and Trichuris vulpis. Approximately 15 minutes before treatment, the dogs were given 100 to 200 g of canned dog food. Ten dogs were treated with nitroscanate (50 mg/kg of body weight, PO), and 8 dogs were given placebo tablets PO. The dogs were euthanatized and necropsied 10 days after treatment and helminths were recovered from the small intestine and cecum. On the basis of the number of worms recovered from treated dogs vs the number recovered from control dogs, we determined the efficacy of nitroscanate to be 99.6% against A caninum, 99.8% against D caninum, and 0% against T vulpis.

Previous work had indicated that the 2 canine hookworms, Ancylostoma caninum and Uncinaria stenocephala, may differ in their susceptibility to treatment with milbemycin oxime. Thus, the study reported here was to examine the effects of this drug on concomitant infections in experimentally infected dogs. Twenty specific-pathogen-free Beagles were inoculated orally with 500 infective-stage larvae from a mixture of larval A caninum and U stenocephala. Quantitative fecal examinations were performed weekly, beginning the day of infection. The dogs were assigned to 2 equal groups, 1 group that received the compound and 1 that received a placebo. The dogs were treated on postinoculation days 30, 60, and 90. For A caninum, egg counts dropped precipitously after the first treatment, and no eggs of this species were found in the feces of any of the treated dogs after the second treatment. The treatments had no significant effect on the mean egg counts made on U stenocephala, although 2 dogs stopped passing eggs entirely after the second treatment. At necropsy, no A caninum were found in any of the treated dogs; the mean number recovered from the control-group dogs was 56.1. Significant difference was not found in the mean number of adult U stenocephala recovered from the treated and control groups (27.0 and 21.7, respectively).

Rodents particularly those belonging to the Muridae family in Malaysia have been well studied because of their medical and economic importance. Much of the work on rodents has been focusing on the identification of endo and ecto parasites. Parasites in rats (Murids) particularly helminthes belonging to the Nematoda family have been described by many workers for more than a century. This
paper is an attempt to compile 50 papers on rodent nematodes that has been published in various scientific journals over the last
100 years in Malaysia. It is hoped that this literature overview on rodent nematodes will come useful as a reference material for the budding parasitologist and biology scientist.

Searching for new, effective and safe methods of treatment of hookworm disease (ancylostomatidosis) of dogs caused by Ancylostoma caninum and Uncinaria stenocephala was realized in the conditions of the Republic of Belarus on the basis of studying of spices composition and dissemination of Ankilostomatidae, age-specific and seasonal disease dynamics, testing of medical and preventive preparations Univerm and Fenbendazol. In the Republic of Belarus Ancylostoma caninum was stated 4,2% of studied cases and Uncinaria stenocephala – in 14,3%. The maximum intensity of the invasion was stated in summer and autumn periods: in cases of individual keeping – 19,4%; in cases of group keeping the disease transformed into enzootic form with 66,7% affect. In winter period there was the lowest invasion – up to 1,4%. The preparation Univerm administrated twofold with feed in dose of 0,1 mg/kg with 24 hours interval proved to be highly effective therapeutic agent with extensefficiency100%. Anthelmintic Fenbendazol administrated once with feed in dose of 0,005 g/kg proved to be highly effective with extensefficiency 80% and intensefficiency 98,84%. Hematological indexes of sick dogs showed the evidence of erythropenia (4,30-4,80 x 10E12/l), hemoglobinemia (113-119 g/l) and eosinophilia (up to 11%), as well as the increased quantity of leukocytes on 5,46% - 23,61 %, and the lowered quantity of lymphocytes on 15,84 % in comparison with healthy animals indexes
