ABSTRACT
We isolated and identified the bacterial pathogen in a pyogenic balanoposthitis patient and investigated the drug resistance and its mechanism of the isolate.Urethral secretions and balanus pustule liquids were collected for microscopic examination after Gram-staining and detection of mycoplasma using Mycoplasma IST 2 kit.The two samples were inoculated on Columbia blood plate,N.gonorrhoeae selective plate and chromID Candida plate for isolation.The obtained colonies were identified by VITEK 2-compact automatic bacterial detection and analysis system.Moreover,PCR was performed to detect 16S rRNA gene of N.gonorrhoeae in the samples and colonies.KB method was applied for detecting susceptibility of five common antibiotics against the isolate.The β-lactamase and extended spectrum β-lactamase confirmatory tests were used to investigate the enzyme production of the isolate as well as drug resistance-associated tetM,TEM,mefA and ermF genes in the isolate were detected by PCR.Results showed that all the clinic samples showed negative for mycoplasma.All the isolating cultivation results of urethral secretions were negative while the balanus pustule liquids provided positive isolating cultivation in the blood and selective plates.The VITEK 2-compact system and 16S rRNA-PCR revealed that the isolated strain belongs to N.gonorrhoeae.The isolate can produce β-lactamases and resist to penicillin G,ciprofloxacin and tetracycline.The tetM,TEM,mefA and ermF genes could be found in the isolate's genome.The patient's balanoposthitis is caused by infection of N.gonorrhoeae.The multidrug resistance of Neisseria gonorrhoeae isolate is closely associated with its carried resistant genes.
ABSTRACT
Infectious pustular vulvovaginitis and balanoposthitis in goats is caused by caprine herpesvirus 1 (CpHV-1), from the Herpesviridae family Alphaherpesvirinae subfamily, sometimes produces abortion, neonatal enteritis and respiratory disease in adult goats. In a herd of 244 dairy and meat goats, physical examinations were performed in does and bucks, presenting vulvar and preputial lesions. Necropsies were done in four discarded animals (one male and two females) and one stillborn; immunohistochemistry (IHC) with bovine herpesvirus 1 (BHV-1) antibodies in prepuce and vulva samples was carried out. Penis and prepuce exfoliative cytology was carried out in six bucks. Prepuce biopsies were collected for electron microscopy and viral isolation. Macroscopically, moderate to severe coalescent multifocal pustular and ulcerative vulvovaginitis was observed; and severe coalescent multifocal pustular and ulcerative balanoposthitis. Microscopically, different degrees of inflammatory lesions with presence of eosinophilic and amphophilic intranuclear inclusion bodies were present. In electron microscopy, the prepuce samples and MBDK cell culture showed several intranuclear viral particles of 150 to 230 nm size. There was slight epithelial cell positivity in IHC with BHV-1 antibodies in vulva and prepuce histological cuts made at necropsy. In the viral isolate was observed a cytopathic effect and the presence of viral particles by microscopy electronic suggesting herpes virus. This is the first documented report suggesting the presence of herpes virus outbreak in caprine herds in Mexico.
La vulvovaginitis y balanopostitis pustular infecciosa en cabras es producida por herpesvirus caprino 1 (CpHV-1), de la familia Herpesviridae subfamilia Alphaherpesvirinae, que ocasionalmente produce aborto, enteritis neonatal y enfermedad respiratoria en las cabras adultas. En un rebaño de 244 cabras de genotipo lechero y cárnico; se realizaron exámenes físicos de hembras y sementales en los que se observaron lesiones vulvares y prepuciales. Se realizó la necropsia de cuatro animales adultos de desecho (dos hembras y un macho) y un neonato muerto; se realizó inmunohistoquímica (IHQ) con anticuerpos de herpesvirus bovino 1 (BHV1) en muestras de prepucio y vulva. Se analizaron las citologías exfoliativas de pene y prepucio de 6 sementales. Se recolectaron y analizaron biopsias de prepucio para microscopía electrónica y aislamiento viral. Macroscópicamente, en las hembras se observó vulvovaginitis pustular y ulcerativa de moderada a grave multifocal coalescente, además de balanopostitis pustular y ulcerativa grave multifocal coalescente en los machos. Microscópicamente, se presentaron lesiones inflamatorias en diferentes grados, con presencia de cuerpos de inclusión intranucleares eosinofílicos y amfofílicos. En microscopía electrónica, las muestras de prepucio y cultivo celular de MBDK presentaron numerosas partículas virales intranucleares de un tamaño de 150 a 230 nm. En los cortes histológicos de prepucio y vulva de las necropsias se detectó una ligera positividad en las células epiteliales con anticuerpos BHV-1. En el aislamiento viral se observó efecto citopático, y la presencia de partículas virales mediante microscopía electrónica sugerentes a herpes virus. Este es el primer informe documentado que sugiere la presencia de herpes virus en rebaños caprinos de México.
