Aims: Peste des petits Ruminants (PPR) is a major viral disease that poses a challenge to small ruminant farming. Its natural occurrence has been complicated by secondary bacterial infection which has led to an increase in morbidity and mortality rates. This study reports the management outcome of natural PPR-infected goats using two types of antibiotics in Nsukka metropolis of Enugu State Nigeria. Methodology: Goats (N=24) were confirmed to be suffering from PPR based on clinical signs and using polymerase chain reaction (PCR). The animals were divided into two groups. Group A was treated with 20% oxytetracycline (N= 10) and group B with procaine penicillin and streptomycin combination (penstrept) (N= 14) injection. Clinical signs, recovery and survivability, temperature, haematology [Packed cell volume (PCV); haemoglobin concentration (Hbconc); red blood cell (RBC) and white blood cell (WBC) counts] and some serum biochemical profiles [alanine aminotransferase (ALT); aspartate transaminase (AST); total protein (TP); Albumin; urea; creatinine; potassium and sodium] were used to assess the efficacy of the antibiotics using standard techniques. Results: The mean temperature, RBC, WBC and urea values of the PPR-infected goats were above their reference ranges, mean albumin values were below the reference range while mean Hbconc, PCV, AST, ALT, TP and creatinine values were within their reference range before the commencement of treatment. Following treatment, clinical signs cleared in 20% and 35.7% of the goats treated with oxytetracycline and penstrep respectively. Death was recorded in 20% and 15% of goats treated with oxytetracycline and penstrep respectively before the end of treatment. Penstrep-treated group showed improvement in their haematological profile. Conclusion: Based on our findings, the use of penstrep in the management of PPR-infected goats gave a better result.

The study evaluated sub-lethal toxicity of commercial glyphosate-based Di-ammonium formulation commonly known as ‘Touchdown’ on haematological profile of Clarias gariepinus juveniles. A total of two hundred catfish juveniles of mean weight 31.07±1.23g and mean length 19.50 ± 0.50cm were exposed to different  concentrations of Di-ammonium formulation (1.26, 2.52, 5.03 and 0.00 mg/l) for eight (8) weeks. Each concentration was treated in triplicate using a static bioassay system. Physico-chemical parameters of the test water were monitored throughout the study period. Results showed that haematocrit (HCT), red blood cell (RBC), haemoglobin (HGB), Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH), Mean Corpuscular Haemoglobin Concentration (MCHC) and Platelets (PLT) counts decreased significantly (p<0.05) with increase in concentrations of Touchdown. Whereas, white blood cell (WBC) counts increased significantly (p<0.05) with increasing concentrations of the glyphosate-based formulation. Water temperature, pH, Total dissolved solid (TDS) and electrical conductivity (EC) increased linearly with increasing concentration, while dissolved oxygen content decreased significantly (p<0.05). The results from this study indicated that Di-ammonium glyphosate–based formulation had negative consequences on the blood of treated fish. In view of this, the application of Di-ammonium glyphosate-based formulation should be done in a sustainable manner with proper regulations.

Peste des petits ruminants (PPR) is a disease of economic and veterinary importance leading to considerable economic losses. PPR affects small domestic and wild ruminants. Sheep and goats are the natural hosts of PPR but cattle, pigs, African buffaloes and camels are also affected by the PPR virus. Clinical signs seen are mainly fever, mucopurulent nasal and ocular discharges, cough, dyspnoea, gastroenteritis leading to severe diarrhoea. The post mortem lesions seen are congested lungs, congestion of gastrointestinal tract, especially the discontinuous streaks of congestion, which is referred to as Zebra stripes or Zebra markings, oedematous and congested retropharyngeal and mesenteric lymph nodes, linear haemorrhages in the intestinal mucosa and splenomegaly. PPR infection is characterized by a rise in packed cell volume (PCV), increase in haemoglobin concentration (HbC), leukopenia with lymphopenia. The serum alkaline phosphatase, alanine aminotransferase and aspartate aminotransferase activities are elevated, blood urea nitrogen and creatinine concentrations are also elevated. The disease is also characterized by disseminated intravascular coagulopathy (DIC) evidenced by prolonged prothrombin time (PT), prolonged activated thromboplastin time (APTT), thrombocytopenia, and hypofibrinogenemia. In PPR infection, serum biomarkers of oxidative stress such as vitamins A, C, E and glutathione activity decreases while serum catalase, superoxide dismutase, glutathione reductase and xanthine oxidase increase. Diagnostic techniques include histopathology, virus isolation, immunocapture enzyme-linked immunosorbent assay (icELISA), Competitive Enzyme Linked Imunnosorbent Assay (cELISA) and Combined Indirect ELISA (CI-ELISA) agar gel immunodiffusion, real-time polymerase chain reaction (RT-PCR), reverse transcription-loop mediated isothermal amplification assay (RT-LAMP), Luciferase immunoprecipitation system (LIPS) and immunohistochemistry. Therefore, this review focused on the aetiology, epidemiology, pathology, immunology, and disease status in Africa, diagnosis, control, prevention, treatment and control of this disease.

Calves 1-2 months old were experimentally infected with eggs of Taenia saginata and clinical and haematological deviations, development and distribution of cysticerci and pathological changes were recorded. The calves infected with 5 000, 10 000 or 50 000 eggs showed an increase in pulse and respiratory rates. The animals that received 50 000 eggs had significantly increased pulse (p<0.05) and respiratory rates (p<0.005). The symptoms were more severe in young, 30-day-old calves infected with 50 000 eggs. Haemoglobin concentration, haematocrit values and red blood cell count decreased, but white blood cell count increased slightly. Lymphocytes and eosinophils also increased up to 88%and 14% (p<0.05), respectively. Most of the cysticerci were not fully formed 1 month post-infection, but at 2 months the cysts were fully mature and at 4 months, some cysts had degenerated. There was no uniformpattern of distribution of cysticerci in the body of infected calves, but the most commonly affected sites were masseter and heart muscles, followed by diaphragm, tongue and other skeletal muscles. The maximum concentration of 8-14 cysticerci per 10 g of tissue was recorded in masseter muscles and heart. The affected parts revealed tissue reactions that included pressure atrophy, necrosis and fibrosis. Microscopically, the lesions comprised infiltration with lymphocytes, plasma cells, eosinophils and macrophages, fibrosis, necrosis and calcification. The tissue reaction was severe in calves infected with 50 000 eggs. The severity of clinical signs, haematological and pathological changes depended mostly on the age of the animals and dose of infection.

Influenza D viruses (IDV) are known to co-circulate with viral and bacterial pathogens in cattle and other ruminants. Currently, there is limited knowledge regarding host responses to IDV infection and whether IDV infection affects host susceptibility to secondary bacterial infections. To begin to address this gap in knowledge, the current study utilized a combination of in vivo and in vitro approaches to evaluate host cellular responses against primary IDV infection and secondary bacterial infection with Staphylococcus aureus (S. aureus). Primary IDV infection in mice did not result in clinical signs of disease and it did not enhance the susceptibility to secondary S. aureus infection. Rather, IDV infection appeared to protect mice from the usual clinical features of secondary bacterial infection, as demonstrated by improved weight loss, survival, and recovery when compared to S. aureus infection alone. We found a notable increase in IFN-β expression following IDV infection while utilizing human alveolar epithelial A549 cells to analyze early anti-viral responses to IDV infection. These results demonstrate for the first time that IDV infection does not increase the susceptibility to secondary bacterial infection with S. aureus, with evidence that anti-viral immune responses during IDV infection might protect the host against these potentially deadly outcomes.

African grey parrots (Psittacus erithacus) are very popular pets, commonly seen in avian clinical practice. Haematological profiles are critical to the understanding of several disease processes, being particularly useful as diagnostic tools in clinical practice, since birds tend to hide clinical signs of disease. We have previously proposed new haematological reference intervals (RI) for captive African grey parrots, and in the present work the basic data obtained was studied in detail to investigate the influence of factors, such as age and sex, on the haematological profile of this bird species. During an 8-year period (March 2009 to July 2017), animals (n = 239) examined in first consultations or check-ups at the Zoològic Veterinaris (Barcelona) were submitted to blood collection at different time points, rendering a total of 459 blood samples. The haematological testing was performed according to the guidelines of the American Society of Veterinary Clinical Pathology to determine the packed cell volume (PCV), haemoglobin (Hb), mean haemoglobin concentration (MHC), mean corpuscular volume (MCV), mean corpuscular haemoglobin concentration (MCHC), total erythrocyte count (TRBC), total leukocyte count (TWBC), and differential leukogram with absolute and relative counts. All the haematological testing was performed in an in-house laboratory as previously described. Animals with 0 to 4 years of age showed higher values of PCV (P &lt; 0.001), Hb (P = 0.023) and RBC (P = 0.018), and lower values of MCHC (P = 0.008), WBC (P = 0.012) and heterophils (P &lt; 0.001) than older animals. There were significant differences exhibited in the monocytes (P = 0.035) between different age groups. Females presented higher PCV, Hb and RBC values (P &lt; 0.001) compared to males. Our results suggest that the age and sex influence the haematological parameters in a significant manner in African grey parrots and should be accounted for when assessing the health status of individuals from this species.

Present study was carried out to investigate the alterations in the haematological profile of juvenile common carp (Cyprinus carpio var. communis) against acute toxicity of organophosphorous compounds, dimethoate and chlorpyrifos. The fish were divided into 5 different experimental groups for range finding tests on the basis of which the doses for definitive tests were selected. The acute bioassay toxicity tests were carried out in triplicates for 96 hours with a control group run parallel to the experiment. Data obtained was analyzed as per Finney’s probit to determine LC50 values. The mean lethal concentration was found 1.1ppm and 3.8ppb respectively for dimethoate and chlorpyrifos. The samples investigated for various haematological parameters such as haemoglobin concentration (Hb), Red blood cell (TEC) and White blood cell (TLC and DLC) counts the heamatocrit (Ht) level, the mean corpuscular volume (MCV) and the mean corpuscular haemoglobin (MCH). Packed cell volume (PCV) and Erythrocyte sedimentation rate (ESR) showed a negative impact of pesticide treated fishes when compared with control. Hb, TEC and Ht were found lower while as ESR and TLC were recorded higher than the control specimens. MCV and MCH showed statistically insignificant differences when compared with control. In DLC, monocyte lymphocyte, neutrophil and basophils were found increased while as eosinophil count was found unaffected than the normal. Studies suggested that the pesticides are potential toxicants for common carps among which chlorpyrifos was found to elicit profound changes intense than dimethoate.

The study evaluated effects of sub-lethal concentrations (0.00, 1.6, 3.2, 6.4, 12.8 g/l) of ethanolic stem bark extracts of ackee, Blighia sapida on haematological profile of Clarias gariepinus (mean weight, 6.95± 1.02 g; total length 11.7±1.32 cm). Each concentration was treated in triplicate using a static bioassay system. The exposure period was 21 days. Physico-chemical parameters of water were monitored throughout the study period. Results revealed that haematocrit, red blood cell, haemoglobin and mean corpuscular haemoglobin concentration counts were significantly (p<0.05) depleted with increase in extract concentration while white blood cell counts increased (p<0.05) linearly from 198.2, 198.5, 208.8, 219.4 and 241.53 x 103 cells/µl in 0.00, 1.6, 3.2, 6.4 and 12.8 g/l respectively. The levels of water temperature increased with extract concentrations while dissolved oxygen and pH contents decreased. The implications of these results showed that stem bark extract of ackee had negative effects on the blood of treated fish. This may further explain the decline in wild fishery resources in the locality where the plant parts were collected. In view of this, the direct use of this plant in harvesting fish by local fisher folks in Southern Nigeria should be discouraged until information that aid its application in a sustainable manner is made available through further studies.

SummaryAge-related trends in serum free thyroxine (FT4) and free triiodothyronine (FT3) concentrations were measured in 7248 euthyroid subjects (age-range 3 months to 106 years). 5700 were patients referred to hospitals for investigation of suspected thyroid dysfunction, but who were diagnosed euthyroid. 1548 were healthy blood donors (age-range 18-63 years) with no indication of thyroid dysfunction. FT4 concentrations were little affected by the age, the sex or the state of health of the subjects in either group. Serum FT3 concentrations were significantly affected by both age and health factors. The upper limit of the euthyroid reference range for young subjects up to 15 years was about 20% higher (10.4 pmol/1) than for adult subjects older than 25 years (8.8 pmol/1). The change in the upper limits typical of young subjects to that typical of adults occurred steadily over the decade 15–25 years. After this age, little further change occurred, especially in healthy subjects. Additionally, the lower limit of the euthyroid range for FT3 was extended by the inclusion in the reference group of patients referred to hospitals. Compared with the lower limit of the FT3 range for healthy subjects (5 pmol/1), the corresponding limit for referred subjects (young or adult) was 3.5–3.8 pmol/1. Broadening of the FT3 reference range was probably brought about by a significant number of patients in the hospital-referred group with the “1OW-T3 syndrome” of mild non-thyroidal illness. Accordingly, FT3 was inferior to FT4 in the discrimination of hypothyroidism, as FT4 was unaffected by this phenomenon. Effects of age and non-thyroidal illness on serum FT3 concentrations require great care when selecting subjects for a laboratory euthyroid reference range typical of the routine workload. Constraints on the choice of subjects for FT4 reference ranges are less stringent.

Abstract Introduction Herpetic whitlows in infants are rare. Previous authors only reported individual case reports. We present a case series of six infants. Materials and Methods This is a retrospective study of six cases of herpetic whitlows in infants seen by the senior author (MMA) over the past 23 years (1995–2017 inclusive). The following data were collected: age, sex, digit involved in the hand, mode of transmission, time of presentation to the author, clinical appearance, presence of secondary bacterial infection, presence of other lesions outside the hand, method of diagnosis, treatment, and outcome. Results All six infants initially presented with classic multiple vesicles of the digital pulp. In all cases, there was a history of active herpes labialis in the mother. Incision and drainage or deroofing of the vesicles (for diagnostic purposes) resulted in secondary bacterial infection. Conclusion The current report is the first series in the literature on herpetic whitlows in infants. We stress on the mode of transmission (from the mother) and establishing the diagnosis clinically. In these cases, no need for obtaining viral cultures or polymerase chain reaction; and no medications are required. Once the vesicles are disrupted, secondary bacterial infection is frequent and a combination of oral acyclovir and intravenous antibiotics will be required.
