Molecular Detection and Characterization of Bovine Diarrhea Virus (BVDV) in Aborted Fetuses and Semen Samples from Paraguay.

Bovine viral diarrhea virus (BVDV) is the most prevalent pathogen in cattle and causes significant economic losses due to its severe clinical manifestations. It belongs to the family Flaviviridae and is distributed in species A, B, and H within the genus Pestivirus. The objective of this study was to detect and characterize BVDV using molecular techniques (RT-PCR) in semen and aborted fetuses samples that were sent to the CEDIVEP (Veterinary Diagnostic Center of Paraguay) laboratory. Seventy-three samples of semen from bulls were analyzed, and 54.7% of the samples were positive for Pestivirus A. The presence of Pestivirus A and H was detected in 2/8 spontaneously aborted fetuses. The genotypes of four individual samples of type A and four samples of type H organs were confirmed by partial sequencing of the 5-UTR region. The presence of BVDV was confirmed by molecular techniques for the first time in our country through its detection in different types of samples, as well as the presence of two genotypes. This suggests that the circulation of this virus can cause significant losses in cattle production in Paraguay.

Contraceptive prevalence in Paraguay.

Contraceptive use, source of contraception, history of abortion, current pregnancy intention, and fertility rates are evaluated for a national sample of women using data from the Paraguay Contraceptive Prevalence Survey, conducted in 1977. The survey found that 15.5 percent of all women aged 15--44 and 23.6 percent of ever-married women were using effective contraceptive methods. The urban/rural difference in contraceptive use paralleled fertility differentials: over 40 percent of ever-married women were using contraception in Greater Asuncion and other urban areas compared with 15 percent in rural areas. Overall, the data indicate that high-parity rural women have the greatest need for family planning services in Paraguay.

The craniofacial pattern of the Lengua Indians of Paraguay.

Lateral cephalometric headfilms of 30 male and 30 female Lengua Indians taken in the Chaco area of Paraguay were compared with a sample of 23 male and 25 female South African Caucasoids with excellent occlusion. The most obvious difference noted between the two population groups was the degree of prognathism evident in the Lengua. This was attributed to the generally shorter anterior cranial base in the latter group rather than to the size or forward positioning of their jaws. The significantly larger ANB (Subspinale, Nasion, Supramentale) angle observed in the Lengua was attributed to one or both of two factors, namely, the short anterior cranial base or the clockwise rotation (forward tipping) of the jaws relative to the anterior cranial base. Chinpoint position relative to the anterior cranial base in the Lengua is not much different from that of our Caucasoid sample. The lower incisor teeth in the Lengua, but not the upper ones, are more labially inclined than those of the Caucasoids.

[Paracoccidioidomycosis: an epidemic in the Republic of Paraguay, the center of South America].

The investigation done on the frequency or incidence of Paracoccidioidomycosis in the Republic of Paraguay, with the cases appeared and registered in the Institute of Pathology of Asuncion, presents an incidence rate of 0.46 per 100,000 in the total population; 0.52 per 100,000 in the population at risk. Considering the exposed masculine population the rate is 1.03 per 100,000 and for the feminine 0.02 per 100,000. The age group most affected is within the 50-54 year range with 3.54 per 100,000, the highest rate of all the groups studied. These are the incidence in a strongly exposed population which is controlled and well known. The period of 10 years (1960/69) which has been chosen for this investigation, shows a frequency of the mixed type (lymphatic-visceral or lymphoma-type) which reaches 25% of the total, and a low frequency for the pulmonary form which reaches a mere 12.5%. The mucocutaneous lesion with the involvement of the regional lymph nodes is the dominating form. Considering three consecutive 5 year periods between 1960 to 1974, no cases with proved pulmonary involvement were found until 1964; from 1965 to 1969 the percentage of pulmonary lesions in all the cases considered was 23.0% and from 1970 to 1974 reached to 38.4%. However, mucocutaneous and the lymphatic-visceral or mixed forms do not show significant variations. The rats are small and represent the incidence of this mycosis. It is suggested that a failure of the immunologic system would be found in those affected by the disease and there would be a strong resistence in the majority of the population exposed or within the endemic area of the infection.

Malignant trophoblastic disease in paraguay.

The incidence of malignant trophoblastic diseases from 1960 to 1969 and 1970 to 1974 in the population of Parguay was low, as shown by the analysis of unselected hospital admissions as compared to the total population. Paraguay showed disease characteristics comparable to those of developing countries where malignant diseases of the trophoblast have elevated frequencies. The apparently high frequencies in lower socioeconomic groups appear to be due to the fact that these groups make up a large proportion of the hospital population. The hardship of poverty predisposes to the hospital concentration of pathologic pregnancies from around the country and to the home delivery of grossly normal gestations. Thus, a biased incidence of diseases results.

Oncicola martini sp. n., and other archiacanthocephala of the Chaco Boreal, Paraguay.

Archiacanthocephalans are reported from mammals of Paraguay. Oncicola martini sp. n. is described from Felis geoffroyi. It is most similar to O. lamasi (Freitas et Costa 1964) comb. n., differing in having larger hooks, all except the smallest of which are barbed. Other species recorded are Oncicola oncicola from Felis geoffroyi (new host record), O. paracampanulata from Felis yagouaroundi, O. luehei from Nasua nasua, Oligacanthorhynchus microcephala from Didelphis albiventris, and O. tortuosa from Euphractus sexcinctus (new host and South American records).

Tapeworms of the Chaco Boreal, Paraguay, with two new species.

Mathevotaenia paraguayae sp. n. is described from Euphractus sexcinctus. It differs from M. didelphidis (Rud.) in having a transverse cirrus pouch anterior to the vagina. Monoecocestus mackiewiczi sp. n. was found in Phyllotis sp. It differs from M. parcitesticulatus Rego in having a much smaller scolex, a poral ovary, and a cirrus pouch 360 to 440 micrometers long. Other species reported are Taenia macrocystis, Taenia omissa, Spirometra mansonoides, Spirometra gracilis, Spirometra longicollis, Diphyllobothrium trinitatis, Atriotaenia parva, and Mathevotaenia tetragonocephala.
