Biology of the non-parasitic phase of the cattle tick Rhipicephalus (Boophilus) microplus in an area of Amazon influence.

Background: Rhipicephalus (Boophilus) microplus is the most important tick species affecting cattle in the world. Under field conditions, the non-parasitic phase of R. (B.

Evaluation of a combination of Citrus aurantium var. Dulcis essential oil and albendazole for the treatment of sheep gastrointestinal nematodes.

Citrus fruits are consumed all over the world and their by-products are used for animal feed and essential oils production. This study aimed to evaluate the in vitro and in vivo activity of Citrus aurantium var. Dulcis essential oil (CaEO) combined with ABZ against benzimidazole resistant Haemonchus contortus.

Seroprevalence of Neospora caninum and risk factors associated with infection in water buffaloes (Bubalus bubalis) from Maranhão State, Brazil.

The aim of this work was to determine the seroprevalence of Neospora caninum in buffaloes (Bubalus bubalis) from Maranhão State, Brazil, and identify risk factors associated with infection. In total, 338 buffaloes of different ages and both sexes from four farms were randomly selected. Information about the study region, animals and management was collected using an epidemiological questionnaire.

Nemabiome metabarcoding reveals differences between gastrointestinal nematode species infecting co-grazed sheep and goats.

Our current understanding of differences in the epidemiology of gastrointestinal nematode (GIN) species in co-grazed sheep and goats is inadequate with reference to the development of sustainable control strategies. The next-generation metabarcoding sequencing method referred to as the 'nemabiome' allows some of these differences to be explored to describe the intensity of co-infecting GIN species. We applied this platform to study sheep and goats that were co-grazed on Guinea grass pasture in northeastern Brazil.

A review on the occurrence of Cochliomyia hominivorax (Diptera: Calliphoridae) in Brazil.

Cochliomyia hominivorax (Coquerel, 1858), the New World screwworm, causes primary myiasis in wild and domestic animals in tropical and subtropical regions of Brazil. Although this species is considered to occur throughout the country, organized information about its recorded distribution has not been available until now. This article aimed to provide a comprehensive review of the historical and current data published on both immature (myiasis) and adult stages of C.

Theileria sp. in water buffaloes from Maranhão State, northeastern Brazil.

Anaplasma marginale and piroplasm species are widespread among Brazilian cattle herds. Both of these tick-borne pathogens hamper livestock production and cause a significant economic impact. Although buffaloes have demonstrated a high level of adaptability, data on tick-borne pathogens are scarcely reported in Brazil.

In vitro and in vivo activity of hydrolyzed Saccharomyces cerevisiae against goat nematodes.

Haemonchus contortus is the most prevalent nematode in tropical and subtropical regions and is responsible for significant losses in small ruminant production systems. Control of this parasite is based on the use of synthetic anthelmintics; although effective, prolonged and indiscriminate use can select for populations of resistant nematodes. Hydrolyzed yeast can help prevent populations of nematodes and is low in cost.

First identification of Cryptosporidium parvum subtype IIaA20G1R1 in water buffalos (Bubalus bubalis).

Cryptosporidium can infect a wide variety of vertebrate animals, including mammals, birds, amphibians, reptiles, and fish. There are few molecular characterizations of Cryptosporidium isolated from water buffalo. Thus, the present study investigated the occurrence and molecular characterization of Cryptosporidium spp.

Hemotropic mycoplasmas infection in water buffaloes (Bubalus bubalis) from northeastern Brazil.

Two species of hemotropic mycoplasmas (HM) are known to infect large domestic ruminants, Mycoplasma wenyonii and 'Candidatus Mycoplasma haemobos'. Although HM has been described in cattle worldwide, data in water buffaloes (Bubalus bubalis) remain scarce. Accordingly, the aim was to determine the occurrence of HM in water buffaloes from northeastern Brazil.

[Anthelmintic activity of aqueous and ethanolic extracts of Morinda citrifolia fruit on Ascaridia galli].

The anthelmintic activity of aqueous and ethanolic extracts of Morinda citrifolia fruit (noni) was evaluated in chicken naturally infected by Ascaridia galli. The anthelmintic activity in vitro was determined in adult parasites. The aqueous and ethanolic extracts were used in the following concentrations: 1.

[Ectoparasites in goat and sheep folks from Alto Mearim and Grajaú Microregion, State of Maranhão].

Goat and sheep folks from Alto Mearim and Grajaú microregion, State of Maranhão, were examined by inspection and by feeling to collected ectoparasites. The specimens were kept in individual bottles for each host sampled with alcohol 70 degrees GL as preserver liquid. The identification was carried out at Universidade Estadual do Maranhão at the laboratory of parasitology.
