The present review aims at presenting different methods for pregnancy diagnosis. Since these methods are to be used in the herds, precocity, sensitivity, specificity, accuracy to predict pregnant and non-pregnant ewes, and the possibility to determine fetal numbers are carefully analysed. The progesterone assay is accurate as early as day 17th after fecundation; but the fertilization day must be precisely known. The pregnancy specific or associated glycoproteins (PSPB/PAG) assay is highly sensitive and specific at day 22 in blood and at day 32 in milk samples. However, this assay does not allow to predict the fetal number. The ultrasonography B-mode used on 30 days of gestation gives very good or excellent performance in terms of sensitivity and specificity depending on the practitioner. The method is also able to predict the real time fetal number. [less ▲]

Efficient methods of diagnosis and prophylaxis of infectious bovine rhinotracheitis must consider the concept of latency of the etiological agent, infectious bovine rhinotracheitis virus (Bovine herpesvirus 1; BHV 1). The identification of BHV 1 in nasal mucus samples or a rise in specific antibodies have to be cautiously interpreted, because they can signify either a primary infection or a reexcretion of the virus after reactivation. The isolated virus can also either be a vaccine or a virulent strain. Another aspect of BHV 1 infection diagnosis is the detection of latent carriers, which are able to transmit the virus to uninfected animals; delayed hypersensitivity test seems to be a good candidate. The classical methods of prophylaxis protect the animal against the disease, but they should also impede the reexcretion of virulent strains by latent carriers. Since, in several countries, attenuated viruses are used as vaccines, a special emphasis has to be laid on the persistence of these vaccine viruses in a latent form in the bovine population.

Background: Human cytomegalovirus (HCMV) has established itself as the most significant cause of congenital infection in the developed world. The objective of this research was prenatal identification of pregnant women at risk for developing active infection due to HCMV as well as to diagnose congenitally infected newborns. Methods: A diagnostic algorithm based on specific immunoglobulin G (IgG), IgM, and, IgG avidity was used to screen serum from 1131 pregnant women enrolled prospectively from 3 municipalities from Havana City, Cuba during 2007–2008. Qualitative multiplex nested PCR and quantitative real time-based PCR testing for HCMV DNA were performed on urine and saliva specimens from women detected with active infection and from their newborns. Results: Most women were seropositive to HCMV (92.7%), with 2.38% (27 women) having active infection. Primary infection was detected in 20 pregnant women (1.77%) while 7 patients (0.62%) had active nonprimary infection. HCMV DNA was detected in specimens from 9 of the 27 pregnant women by both PCR methods. HCMV congenital infection was diagnosed in 12 (1.06%) of the 26 live children born from 25 mothers with active infection, for a vertical transmission rate of 46.2%. Two fetal deaths were reported from 2 women with active infection; furthermore 2 newborns were symptomatic at birth and 2 showed sequelae during the follow-up done until 6 months age. Conclusions: Mothers with active infection during the pregnancy and with HCMV excretion had significant risks, RR = 1.16 and RR = 1.35, respectively, to have congenitally infected children. [less ▲]

Brucellergene OCB (Rhone-Merieux) was used as an allergen to define the intrinsic parameters of a skin test and to compare its properties with serology for the diagnosis of bovine brucellosis. The skin test was also evaluated for its capacity to solve problems associated with false positive reactions in serological tests. The optimal reading delay for the skin test was 72 hours. The brucellosis allergic reaction was two to three times less intense than the tuberculosis allergic reaction. An increase of 1.1 mm or more in the skin thickness was therefore considered to be an adequate cut-off. The specificity calculated for 1192 brucellosis-free animals (including animals from brucellosis-free herds in which false positive serological reactions had been reported) was 99-83 per cent (95 per cent confidence interval [CI] 99-40 to 99-98 per cent). The sensitivity determined from 27 experimentally infected heifers ranged from 93 per cent (95 per cent CI 76 to 100 per cent) to 78 per cent (95 per cent CI 58 to 91 per cent) when measured respectively one and six months after the infection. Allergic reactions could be detected in vaccinated animals up to four-and-a-half years after the vaccination. On the other hand, no sensitisation was recorded in naive animals after up to eight monthly injections of the allergen. The skin test gave valuable information, in combination with the serological tests, in both acute and chronic brucellosis. The skin test discriminated brucellosis clearly from false positive serological reactions due to infections with Yersinia enterocolitica O9. [less ▲]

AIM: To describe and discuss the merits of various direct and indirect methods applied in vitro (mainly on blood or milk) or in vivo (allergic test) for the diagnosis of brucellosis in animals. METHODS: The recent literature on brucellosis diagnostic tests was reviewed. These diagnostic tests are applied with different goals, such as national screening, confirmatory diagnosis, certification, and international trade. The validation of such diagnostic tests is still an issue, particularly in wildlife. The choice of the testing strategy depends on the prevailing brucellosis epidemiological situation and the goal of testing. RESULTS: Measuring the kinetics of antibody production after Brucella spp. infection is essential for analyzing serological results correctly and may help to predict abortion. Indirect ELISAs help to discriminate 1) between false positive serological reactions and true brucellosis and 2) between vaccination and infection. Biotyping of Brucella spp. provides valuable epidemiological information that allows tracing an infection back to the sources in instances where several biotypes of a given Brucella species are circulating. Polymerase chain reaction and new molecular methods are likely to be used as routine typing and fingerprinting methods in the coming years. CONCLUSION: The diagnosis of brucellosis in livestock and wildlife is complex and serological results need to be carefully analyzed. The B. abortus S19 and B. melitensis Rev. 1 vaccines are the cornerstones of control programs in cattle and small ruminants, respectively. There is no vaccine available for pigs or for wildlife. In the absence of a human brucellosis vaccine, prevention of human brucellosis depends on the control of the disease in animals. [less ▲]

Cyst infection is a diagnostic challenge in patients with autosomal dominant polycystic kidney disease (ADPKD) because of the lack of specific manifestations and limitations of conventional imaging procedures. Still, recent clinical observations and series have highlighted common criteria for this condition. Cyst infection is diagnosed if confirmed by cyst fluid analysis showing bacteria and neutrophils, and as a probable diagnosis if all four of the following criteria are concomitantly met: temperature of >38 degrees C for >3 days, loin or liver tenderness, C-reactive protein plasma level of >5 mg/dL and no evidence for intracystic bleeding on computed tomography (CT). In addition, the elevation of serum carbohydrate antigen 19-9 (CA19-9) has been proposed as a biomarker for hepatic cyst infection. Positron-emission tomography after intravenous injection of 18-fluorodeoxyglucose, combined with CT, proved superior to radiological imaging techniques for the identification and localization of kidney and liver pyocyst. This review summarizes the attributes and limitations of these recent clinical, biological and imaging advances in the diagnosis of cyst infection in patients with ADPKD. [less ▲]

Our study showed the potential of a surrogate of the oesophageal pressure, the jaw motion, and a dedicated automatic analysis to diagnose the obstructive sleep apnoea and hypopnoea syndrome (OSAHS). Twentyfour patients were recorded in hospital settings and the jaw motion of fifteen of them was also recorded at home with an ambulatory device. The apnoea and hypopnoea index (AHI) of the gold standard, AHI_PSG, and the two AHI from the automatic analysis of the jaw motion, AHI_H (hospital) and AHI_A (ambulatory), were compared : AHI_PSG Vs AHI_H showed good correlation (r = 0.97) and under-estimation (slope p = 0.76). AHI_A Vs AHI_H revealed good reliability with r = 0.98 and slope p = 0.99. Finally, AHI_PSG Vs AHI_A showed very good accuracy of the diagnosis with sensitivity of 90% and specificity of 100%.
