2021 ◽  
pp. 1-9

During 2013-2018 A total of 3457 different animals were admitted to the Teaching Veterinary Hospital (TVH), College of veterinary Medicine, University of Bahri . Blood samples were taken from the ear vein and smears were prepared, stained and examined in the laboratory for babesia parasite. A total of 687 (19.87%) samples were positive out of which 433(63.02%) were cattle,55(8.01%)sheep,177(25.76%)goat, 13 (1.89%) camel , 5(0.72%) horses, one(0.15%) donkey, one(0.15%)deer , and 2(0.30%) dogs . Compared to other years, the positive cases of babesosis were higher, 337 (49.05%) during 2017. In cattle, during the study period there was fluctuation amongst different seasons comparing between different years. However, comparing between seasons, generally the prevalence of babesia was significantly higher during summer (p˂0.05) and autumn (p˂0.01).In sheep, comparing between different years there was fluctuation amongst different seasons. However, comparing between seasons, generally the prevalence of babesia was significantly higher during autumn (p˂0.05). In goats, between years there were fluctuations for babesia prevalence in different seasons, while comparing between seasons, winter had significantly (p˂0.05) higher values. It is concluded that, babesiosis is one of the serious health problems in North Bahri that may negatively affect animals’ production mainly cattle and goats. This study also revealed that, babesia showed seasonal fluctuations in its occurrence. Restrict tick control strategies should be implemented by the veterinary authorities . A seroprevalence study should be performed for genetic characterization of babesia in the area. Moreover, studies to investigate drug resistance and epidemiological studies should be conducted amongst animal labors and owners.

SUMMARYThe development of simple, sensitive and rapid methods for the detection and identification ofToxoplasma gondiiis important for the diagnosis and epidemiological studies of the zoonotic disease toxoplasmosis. In the past 2 decades, molecular methods based on a variety of genetic markers have been developed, each with its advantages and limitations. The application of these methods has generated invaluable information to enhance our understanding of the epidemiology, population genetics and phylogeny ofT. gondii. However, since most studies focused solely on the detection but not genetic characterization ofT. gondii, the information obtained was limited. In this review, we discuss some widely used molecular methods and propose an integrated approach for the detection and identification ofT. gondii, in order to generate maximum information for epidemiological, population and phylogenetic studies of this key pathogen.

Fifty Brazilian rabies viruses, collected from many different animal species and several regions of the country, were characterized by partial sequencing of the central, variable region of the P gene, a locus useful for sensitive molecular epidemiological studies. Phylogenetic analysis of the sequences, which included comparison with other rabies strains recovered from throughout the Americas, identified three main groups of Brazilian viruses, arbitrarily designated BRL-1 to BRL-3. BRL-1 was found in terrestrial carnivores and clusters with other American strains of the cosmopolitan lineage. BRL-2 comprised two distinct isolates, recovered from two species of non-haematophagous bats, that had evolutionary links to insectivorous-bat-derived strains of North America. BRL-3 consisted of isolates from vampire bats and from livestock species probably infected via contact with vampire bats. The terrestrial group was further subdivided into three subtypes: BRL-1a was associated exclusively with dogs and cats, while BRL-1b and BRL-1c were found exclusively in hoary foxes. These observations strongly support the role of the Brazilian hoary fox as a rabies reservoir. Screening of representative Brazilian rabies viruses against a collection of anti-rabies monoclonal antibodies (mAbs) identified a small panel of mAbs that could be used to discriminate between all Brazilian subgroups as defined by genetic classification in this study.

Staphylococcus aureus está entre os microrganismos que apresentam as maiores taxas de morbidade e mortalidade em seres humanos e animais. Linhagens de S. aureus resistentes a meticilina podem causar surtos de infecção em todo o mundo, o que contribui para a escassez de arsenal terapêutico. Este trabalho analisou o perfil epidemiológico de estirpes de S. aureus isoladas de pessoas que trabalham em contato com animais em um hospital veterinário com gado leiteiro e também em amostras de leite de vacas acometidas por mastite. As estirpes de S. aureus isoladas foram caracterizadas fenotipicamente por meio de antibiograma, testes de catalase e coagulase, e pelo teste de Voges-Proskauer. As amostras também foram caracterizadas genotipicamente pela técnica de Analise de Restricao de DNA Ribossomico Amplificado (ARDRA-PCR). Das 218 estirpes isoladas, 27 foram identificados como S. aureus (12%). Entre essas, quatro estirpes foram resistentes a oxacilina e duas classificadas como SARM (S. aureus resistente a meticilina). A ocorrência de estirpes de S.aureus isoladas entre o pessoal que trabalha em contato com os animais foi baixa (2%), mas estirpes identificadas como SARM foram encontradas na equipe clínica. As análises de ARDRA realizadas com as enzimas de restrição HindIII e HinfII demonstraram que S. aureus isolados de diferentes indivíduos que trabalhavam com animais foram agrupados no mesmo cluster. Quando a ARDRA foi realizada com HaeIII foi observada formação de dois grupos, mas os isolados não se correlacionaram. Conclusão: a ocorrência de estirpes de S. aureus isoladas foi maior na equipe clínica, apresentando também correlação de 100% nos ensaios bioquímicos e moleculares.

Nineteen isolates of bovine viral diarrhea virus (BVDV) from Brazil were genetically characterized through partial nucleotide sequencing and analysis of the 5'UTR region. The isolates were grouped as BVDV-1 (11/19), BVDV-2 (6/19) or "atypical" pestivirus (2/19). Among the BVDV-1, eight isolates were classified as subgenotype BVDV-1a, whereas most (4 out of 6) BVDV-2 belonged to subgenotype 2b. Two isolates from aborted fetuses were not classified into any genetic group, being considered atypical BVDVs. Genetic diversity among Brazilian BVDV isolates may be responsible for vaccination and diag-nostic failure and therefore may influence the control strategies for BVDV infection in the country.

Tick-borne encephalitis virus (TBEV) was isolated for the first time in Sweden in 1958 (from ticks and from 1 tick-borne encephalitis [TBE] patient).1 In 2003, Haglund and colleagues reported the isolation and antigenic and genetic characterization of 14 TBEV strains from Swedish patients (samples collected 1991–1994).2 The first serum sample, from which TBEV was isolated, was obtained 2–10 days after onset of disease and found to be negative for anti-TBEV immunoglobulin M (IgM) by enzyme-linked immunosorbent assay (ELISA), whereas TBEV-specific IgM (and TBEV-specific immunoglobulin G/cerebrospinal fluid [IgG/CSF] activity) was demonstrated in later serum samples taken during the second phase of the disease.
