Caracterização molecular de cryptosporidium spp. em filhotes caninos

Parasitos do gênero Cryptosporidium pertencem ao filo Apicomplexa, com localização intracelular e extracitoplasmática obrigatória e se desenvolvem principalmente na superfície das células epiteliais de hospedeiros vertebrados. O cão, possível fonte de infecção humana, elimina oocistos fecais deste protozoário com grande potencial zoonótico no ambiente. O presente estudo teve como objetivo caracterizar molecularmente Cryptosporidium spp. obtidos de amostras fecais de filhotes caninos (naturalmente infectados). Um total de 200 cães foram examinados, sendo 100 machos e 100 fêmeas, 111 de padrão racial determinado e 89 sem raça definida (SRD). Destes, 81 animais, 43, 48 e 28 tinham até dois, de dois a três; de três a seis e de seis a doze meses, respectivamente. Conforme sua origem, os animais eram provenientes dos Municípios de Araçatuba e Votuporanga, SP, sendo que 126 eram de domicílios; 11 mantidos em Centros de Zoonoses; 50 de Pet Shops; 12 de um criatório e uma (0,5%) era errante e havia sido adotada. A ocorrência de Cryptosporidium spp. foi de 1% (2/200). Ambas eram fêmeas, SRD, com idade entre 60 e 90 dias. A de origem residencial apresentava fezes pastosas com coloração castanho claro e a outra, resgatada do CCZ, material fecal escurecido de consistência liquefeita. O sequenciamento dos fragmentos amplificados confirmou a presença de Cryptosporidium canis. A partir dos resultados obtidos neste trabalho, é possível concluir que 2% dos caninos analisados eram hospedeiros de C. canis

Parasitos e comensais intestinais em pacientes neoplásicos submetidos à quimioterapia

The objective of this study was to verify the prevalence of intestinal parasites and/or commensals in the neoplastic patients undergoing chemotherapy. Stool samples were analyzed by the method of Lutz (1919) and Rugai (1954), in triplicate. This work was composed of three groups, the first one (GI) formed by neoplastic patients that are not undergoing chemotherapy, the second (GII) comprised patients who were undergoing chemotherapy, and the third group (GIII) consisting of patients who completed chemotherapy. A total of 30 patients (GI-5, GII-18 and GIII-7) were screened at the Assis Regional Hospital of the Unified Health System of Assis, São Paulo.Additional information on antiparasitic treatment and tumor type were obtained by questionnaire. The positivity was 66.7% (20 cases) for intestinal parasites and/or commensals. The helminths were Ascaris lumbricoides (36.7%), Hookworms (20%) and Hymenolepis diminuta (3.3%). Among the highlights are protozoan Giardia lamblia (46.7%), Entamoeba coli (6.7%), E. histolytica /dispar (3.3%), Endolimax nana (3.3%) and Iodameba butschlii (3.3%). The high frequency of intestinal parasites and/or commensals in the neoplastic patients can be attributed to poor personal hygiene and lack of immunity to reinfection and poor knowledge of the prophylaxis of infection by protozoa and helminths. The results indicate the necessity of adopting a new criterion for neoplastic patients undergoing chemotherapy, primarily performing parasitological diagnosis, treatment and monitoring of cure of intestinal parasitic infections in this risk group.

Pesquisa de salmonella em mutuns (mitu mitu) mantidos em cativeiro

We collected 50 samples of curasow feces from the Scientific and Cultural Breeding Center in the city of Poços de Caldas. The samples were enriched in broth medium Tetrationato and Cystine-selenite and plated on Salmonella Shigella (SS), Mac Conkey (MC), endo-C (EC), Brilliant Green (VB) and Eosyn Methilen Blue EMB, remaining at 37 °C for 24h. Colonies suspected of Salmonella were inoculated in tubes containing Agar Triple Sugar Iron (TSI) and again incubated at 37 ºC for 24h. Tubes with characteristic growth were submitted to slide agglutination test with polyvalent somatic and flagellar serum. The medium SS, MC and VB were the most efficient for growing, and 36% of samples were positive for Salmonella spp. As birds are important reservoirs of Salmonella spp and it may represent a high risk to human health, there is a need to implement a cleaning routine in enclosures avoiding contamination between the enclosures and the consequent entrainment of these micro-organisms, by the keepers until their homes or other venues. The presence of Salmonella in breeding centers may be responsible for lower hatchability of eggs, undermining the purpose of the entity, which is to study and maintain the various birds species.

Inorganic and organic trace mineral supplementation in weanling pig diets

A study was conducted to evaluate the s of dietary inorganic and organic trace minerals in two levels of supplementation regarding performance, diarrhea occurrence, hematological parameters, fecal mineral excretion and mineral retention in metacarpals and liver of weanling pigs. Seventy piglets weaned at 21 days of age with an average initial body weight of 6.70 ± 0.38 kg were allotted in five treatments: control diet (no added trace mineral premix); 50% ITMP (control diet with inorganic trace mineral premix supplying only 50% of trace mineral requirements); 50% OTMP (control diet with organic trace mineral premix supplying only 50% of trace mineral requirements); 100% ITMP (control diet with inorganic trace mineral premix supplying 100% of trace mineral requirements); and 100% OTMP (control diet with organic trace mineral premix supplying 100% of trace mineral requirements). Feed intake and daily weight gain were not affected by treatments, however, piglets supplemented by trace minerals presented better gain:feed ratio. No differences were observed at calcium, phosphorus, potassium, magnesium, sodium and sulfur excreted in feces per kilogram of feed intake. Treatments did not affect calcium, phosphorus, magnesium, sulfur and iron content in metacarpals. Trace mineral supplementation, regardless of level and source, improved the performance of piglets.
