Resumo: | The objective of this study was to determine the epidemiological situation of infection by Tritrichomonas foetus and Campylobacter fetus subsp. venerealis in cattle at Brejo Paraibano microregion, Northeastern Brazil, identifying the possible risk factors associated with T. foetus infection. For the study of T. foetus, 349 samples of cervico-vaginal mucus and smegma were collected in beef and dairy cattle (290 females and 59 males) in 31 farms and for C. fetus subsp. venerealis, 273 samples of cervico-vaginal mucus from dairy cows from 19 farms were collected. Polymerase Chain Reaction was used to identify the DNA of the agents and culture with Modified Diamond medium for isolation of T. foetus. For analysis of risk factors associated with Tritrichomonas foetus infection in bovine species, univariate analysis of the variables of interest was performed by the Pearson chi-squared test, or Fisher's exact test, when necessary. Subsequently, logistic regression was performed considering PCR (positive or negative) as the dependent variable for trichomoniasis. Thematic maps were prepared with prevalence distributions in the studied area. The prevalence of C. fetus subsp. venerealis infection in cows was 7.7% (21/273) (CI 95% 4.8% – 11.5%), and 31.6% (6/19) of the farms showed at least one positive animal. The prevalence of T. foetus infection was 3.7% (13/349) (CI 95%, 2.1 - 6.4%). Regarding the gender, a prevalence of T. foetus infection of 4.5% (females) and 0.0% (males) was observed. The percentage of farms that had at least one positive animal for T. foetus was 19.3% (6/31). In culture, no samples were positive for T. foetus. The risk factor associated with T. foetus infection identified in this study was contact of females with bulls of other farms (OR 5.9; CI 1.5 - 22.4). This is the first report of C. fetus subsp. venerealis infection in dairy cows in this region of Brazil and the first in Brejo Paraibano microregion that analyzed T. foetus infection in cattle. To reduce risk of infection, it is recommended to adopt an artificial insemination program on the farms with negative bull semen, as well as a vaccination program against Bovine Genital Campylobacteriosis to stimulate immunity to reduce the occurrence of infection and possible reproductive problems. Contact of females with males of other farms should be avoided, especially when the health status of these bulls is not known regarding these two infections. |

Para pesquisa de T. foetus foram coletadas 349 amostras de muco cérvico vaginal e esmegma em bovinos de corte e leite (290 fêmeas e 59 machos) em 31 propriedades e para pesquisa de C. fetus subsp. venerealis foram coletadas 273 amostras de muco cérvico vaginal de vacas leiteiras procedentes de 19 propriedades. Para a pesquisa do DNA dos agentes utilizou-se a Reação em Cadeia da Polimerase e cultivo com meio Diamond Modificado para isolamento de T. foetus. Para análise dos fatores de risco associados à infecção por Tritrichomonas foetus na espécie bovina, foi realizada uma análise univariada das variáveis de interesse pelo teste qui-quadrado de Pearson, ou Exato de Fisher, quando necessário. Posteriormente foi realizada uma regressão logística considerando como variável dependente para Tricomonose a PCR (positivo ou negativo). Foram elaborados mapas temáticos com as distribuições das prevalências na área estudada. A prevalência da infecção por C. fetus subsp. venerealis em vacas foi 7,7% (21/273) (I.C. 95%; 4,8 - 11,5%) e 31,6% (6/19) das propriedades apresentaram ao menos um animal positivo. A prevalência da infecção por T. foetus foi 3,7% (13/349) (I.C. 95%; 2,1 – 6,4%). Em relação ao sexo, observou-se uma prevalência da infecção por T. foetus de 4,5% (fêmeas) e 0,0% (machos). A porcentagem de propriedades que apresentaram ao menos um animal positivo para T. foetus foi de 19,3% (6/31). No cultivo, nenhuma amostra foi positiva para T. foetus. O fator de risco associado à infecção por T. foetus identificado neste estudo foi contato de fêmeas com touros de outras propriedades (OR 5,9; I.C. 1,5 – 22,4). Este é o primeiro relato da infecção por C. fetus subsp. venerealis em vacas leiteiras nesta região do Brasil e o primeiro na microrregião do Brejo Paraibano a analisar a infecção por T. foetus em bovinos. Para diminuir os riscos de infecção, recomenda-se a adoção de um programa de inseminação artificial nas propriedades com sêmen de touros negativos, bem como um programa de vacinação contra a Campilobacteriose Genital Bovina para estimular a imunidade, com o intuito de reduzir a ocorrência da infecção e possíveis problemas reprodutivos. O contato das fêmeas com machos de outras propriedades deve ser evitado, principalmente quando não se conhece o status sanitário desses touros em relação a estas duas infecções.Submitted by Mario BC (mario@bc.ufrpe.br) on 2018-06-15T12:48:17Z No. of bitstreams: 1 Ruy Brayner de Oliveira Filho.pdf: 2028711 bytes, checksum: c66c5e9d041a3c1b673438d6c412bde8 (MD5)Made available in DSpace on 2018-06-15T12:48:17Z (GMT).

The objective of this study was to determine the epidemiological situation of infection by Tritrichomonas foetus and Campylobacter fetus subsp. venerealis in cattle at Brejo Paraibano microregion, Northeastern Brazil, identifying the possible risk factors associated with T. foetus infection. For the study of T. foetus, 349 samples of cervico-vaginal mucus and smegma were collected in beef and dairy cattle (290 females and 59 males) in 31 farms and for C. fetus subsp. venerealis, 273 samples of cervico-vaginal mucus from dairy cows from 19 farms were collected. Polymerase Chain Reaction was used to identify the DNA of the agents and culture with Modified Diamond medium for isolation of T. foetus. For analysis of risk factors associated with Tritrichomonas foetus infection in bovine species, univariate analysis of the variables of interest was performed by the Pearson chi-squared test, or Fisher's exact test, when necessary. Subsequently, logistic regression was performed considering PCR (positive or negative) as the dependent variable for trichomoniasis. Thematic maps were prepared with prevalence distributions in the studied area. The prevalence of C. fetus subsp. venerealis infection in cows was 7.7% (21/273) (CI 95% 4.8% – 11.5%), and 31.6% (6/19) of the farms showed at least one positive animal. The prevalence of T. foetus infection was 3.7% (13/349) (CI 95%, 2.1 - 6.4%). Regarding the gender, a prevalence of T. foetus infection of 4.5% (females) and 0.0% (males) was observed. The percentage of farms that had at least one positive animal for T. foetus was 19.3% (6/31). In culture, no samples were positive for T. foetus. The risk factor associated with T. foetus infection identified in this study was contact of females with bulls of other farms (OR 5.9; CI 1.5 - 22.4). This is the first report of C. fetus subsp. venerealis infection in dairy cows in this region of Brazil and the first in Brejo Paraibano microregion that analyzed T. foetus infection in cattle. To reduce risk of infection, it is recommended to adopt an artificial insemination program on the farms with negative bull semen, as well as a vaccination program against Bovine Genital Campylobacteriosis to stimulate immunity to reduce the occurrence of infection and possible reproductive problems. Contact of females with males of other farms should be avoided, especially when the health status of these bulls is not known regarding these two infections. |
