The CD4 cell counts and HIV-1 RNA levels were determined using standardized protocols. HPV status and HPV 16 detection were ascertained respectively by My09/11 consensus primers and type specific primers. Colpocytology was performed at the first or subsequent visit to the service. Among women, 98.6% of them were under antiviral treatment, 92.1% had over 200 CD4 cells/mm3, 62.9% had detectable HIV RNA, 60.7% were HPV infected and 21.2 % harbored the HPV type 16. Normal/inflammatory results were prevalent (57.1%) and 7.9% of the patients had HSIL. Studying demographic data and HIV markers that could affect HPV infection, we found that time elapsed since positive diagnosis of less than four years was a significant factor. First sexual intercourse beginning earlier than 17 years, people younger than 30 years and white ethnicity were also linked to HPV infection. Alcohol use was marginally related to HPV prevalence. Patients with severe immune depression were strongly predisposed to HPV infection (from 90.9% of patients carrying less than 200 cells/mm3 to 45.5% in those with CD4 cell level above 500 cells/mm3) and the development of cervical lesions. There was no relation between HIV immune status and HPV type 16, but HIV seropositive women with abnormal cytology were three times more likely to harbor this HPV type. The high HPV prevalence as opposed to absence of cancer cases was probably due to the moderate immune status of the women studied added to routine cancer prevention exams.

Oncogenic HPV types cause pre-malignant lesions that can progress to cervical carcinoma. In the male genital tract, most HPV infections are sub-clinical and associated with a vicious circle [stet] of treatment-reinfection of women. Nevertheless, HPV pathogenic processes are still poorly understood. The literature suggests that different HPV types can be found among sexual partners. In our study, we aimed to verify HPV infections in female patients as well as in their sexual partners, to test this hypothesis. The HPV DNA prevalence in women with Cervical Intraepithelial Neoplasia (CIN) was 92.5% compared with 25% for normal women, with a statistically significant difference (p<0.001). In male samples, the HPV DNA prevalence in partners from CIN women was 50% and for normal women partners, it was 17.5%. In the group of CIN women, we observed that 20 couples had HPV DNA in both partners. However, only 50% of the couples shared the same HPV type. In the group of normal women, only 6 couples were simultaneously infected by HPV, and from them only 33.3% had the same virus type. These results may be attributed to differences in local immunity and organization of the genital epithelia of each sex. On the other hand, female lesions would not be the result of re-infection by sexual partners, but rather a true recurrence of a latent infection. Finally, such 40% of agreement among all couples leads us to suggest a vicious circle [stet] of infectious processes, perpetuating HPV in the sexually active population.

The hemagglutination inhibition (HI) test is considered to be the standard serology test, for detection of antibodies against Newcastle Disease Virus (NDV). However, HI test tends to give false positive results in serum samples of some species, including ostriches. In this study, kaolin was used to eliminate the nonspecific hemagglutination inhibitors in ostrich serum samples. Twenty-seven non-kaolin-treated ostrich samples reacted to the test and the titres ranged from 2 to 64. However, these samples did not react when they were kaolin-treated. The controls did not show any variance on antibodies titres, regardless of treatment with kaolin. The use of kaolin in the routine serodiagnosis of ND not only relieves adsorption of serum samples with avian erythrocytes, but also contributes to the reduction in the maintenance of red blood cells donor birds.

Human infections associated with the infected animals have been also observed in the area. Specimens of 102 animals were collected in 34 farms in the period May 2006 to October 2007, mainly serum samples and also crusts and vesicular fluids. The clinical specimens were submitted to a plaque reduction neutralization test, reverse transcriptase polymerase chain reaction (RT-PCR) test, electron microscopy examination and virus isolation in a Vero cell line. Orthopoxvirus infection could be demonstrated by at least one of the laboratory methods in 92 animals, and lesions were observed on the udder of dairy cattle and around mouth and nose of calves in contact with infected adults. The orthopoxvirus infections are spreading in the area and may be already considered a important zoonosis, with substantial economic losses in the dairy cattle due to reduction of milk production and permanent lesions in the udder, like losses of teats.
